A slag blocking cone is a refractory product similar to a cone with a smaller diameter tilting rod, and has three steel tapping grooves. By using slag blocking cones, the composition of molten steel can be stabilized, the phenomenon of phosphorus recovery in molten steel can be reduced, the quality of molten steel can be improved, the absorption rate of alloy elements can be increased, and the consumption of refractory materials can be reduced. Therefore, slag blocking cones are very popular.     Working principle (3 steps)   Density difference suspension: Steel slag density<slag blocking hammer density<molten steel density, automatically floating at the interface between steel slag and molten steel.   Suppressing eddy currents: The hammer groove disperses the molten steel vortex, preventing steel slag from being drawn into the steel outlet.   Final sealing: put into operation when the steel tapping reaches 90% -95%; When the molten steel is running out, the hammer head sinks to block the steel outlet, leaving only the molten steel flowing out of the groove, and the steel slag is completely intercepted.      A slag blocking ball is a core metallurgical refractory material used in the steelmaking process of a converter to physically intercept slag during the tapping stage and prevent steel slag from flowing into the ladle. It is also a key component for achieving "slag free tapping".    

Core wire originated in the 1980s as an external refining technology developed from jet metallurgy. The original technology was to throw alloy blocks into steel and molten iron, sprinkle powder, and remove impurities from the steel, which could lead to problems such as high burning loss and low alloy recovery rate. The dust is large and does not meet the national environmental standards. Workers are required to operate it ,There are safety hazards in the working environment. The reaction is uneven and the quality is difficult to control. And the core wire solves these pain points, replacing extensive feeding. Core wire is a thin steel strip used to wrap deoxidizers, desulfurizers, and alloy powders (such as silicon calcium, calcium iron, carbon, rare earths, etc.), and then rolled into large coils. When working, a wire feeder is used to drive the steel deep into the molten steel, causing the steel strip to melt at high temperatures and release the wrapped material into the steel and molten iron for reaction, resulting in Impurities float to the surface and turn into slag, which is then scraped off. Thereby improving the purity of the molten steel. The advantages of core wire are also obvious: Significantly improve alloy yield Powder reacts more thoroughly deep in molten steel Wire feeding machine, easy to control operation process Small dust, environmentally friendly and safe operating environment   The technical specifications of our factory's core wire are: (1) Steel wire diameter: 13-13.5mm (2) Thickness of steel: 0.4 mm 0.2 mm (3) Powder content: 225g/m 10g/m (4) Powder/steel: 60/40. (5) Wire length: 5000-5500m. (6) Coil weight: 1000-1800kgs. (7) Coil width: 600-800 mm (8) Steel wire winding: horizontal (9) Packaging: In a plastic covered steel cage   The packaging method of our factory's core wire: 1. Vertical coils in steel cages on wooden (or steel) pallets, plastic shrink wrap, marked. Or according to customer requirements 2. The core wire is first packaged with steel strip, then wrapped with waterproof plastic film and protected with steel cage, and then wrapped with outer packaging

In the continuous casting process of steel production, a seemingly inconspicuous material — ladle drainage sand — plays a crucial "gatekeeper" role. At present, chromium-based drainage sand commonly used by domestic steel mills has become a key auxiliary material, along with insulating covering powder, to ensure smooth production and improve efficiency due to its high automatic pouring rate. Core components and structure: three layers of "defense line" ensure controlled outflow of molten steel.Chromium drainage sand is mainly composed of chromite sand, quartz sand, and specific additives. When it is put into the bottom nozzle of the ladle and comes into contact with high-temperature molten steel, a unique three-layer structure will quickly form... Molten layer: The topmost layer formed by the melting of some sand particles in contact with the molten steel. This layer must have a moderate thickness, thus placing extremely high demands on the high-temperature resistance of the drainage sand.Sintering layer: The intermediate layer is formed by high-temperature sintering, which is dense and strong. It effectively prevents excessive infiltration of molten steel downwards, and natural pouring relies on the self weight pressure of the molten steel to break through this layer. Therefore, this layer requires high sintering temperature and appropriate thickness.Loose layer: the lowest layer that maintains the original particle state. It requires optimized particle ratio and excellent fluidity to ensure smooth outflow when needed, and to open the water outlet.Performance requirement: Multi dimensional indicators create high efficiency and reliabilityTo perform its functions perfectly, high-quality drainage sand needs to meet a series of rigorous comprehensive performance indicators:Physical properties: It is preferable for the particle shape to be close to circular to ensure good fluidity; Simultaneously, it needs to have low thermal conductivity and low expansion value to prevent explosion when heated.Chemical and thermal performance: It must have strong chemical stability and not undergo violent reactions with molten steel; High fire resistance, able to withstand high temperature impact; And it has moderate sintering properties and excellent thermal insulation performance.Usage status: Keep fully dry to avoid safety hazards caused by water evaporation.In summary, although drainage sand is not the final product, its perfect balance of dryness, flowability, chemical stability, thermal insulation, sintering suitability, and fire resistance directly determines whether the ladle water inlet can achieve reliable and automatic opening, thereby ensuring the safety, efficiency, and continuity of steel production. The 'big science' in this' small material 'is precisely the microscopic manifestation of the refined and efficient operation of modern steel industry.

Driven by high-end manufacturing and energy transformation, the application of silicon carbide (SiC) products, including black silicon carbide and green silicon carbide, is constantly penetrating into multiple core industrial fields, becoming a key refractory material for improving equipment durability, production efficiency, and system reliability. With its excellent wear resistance, high temperature resistance, corrosion resistance, and high thermal conductivity, silicon carbide plays an important role in both traditional heavy industry and emerging high-tech industries.Traditional industrial field: wear-resistant and anti-corrosion, significantly extended service lifeIn industries such as steel, mining, and power, silicon carbide products have become the preferred material for high wear and high corrosion environments. For example, equipment such as blast furnace slag conveying pipelines, dust removal systems, and exhaust fans used in thermal power generation can have a service life of 5 to 10 years, significantly reducing replacement frequency and maintenance costs, and improving production continuity and economic benefits. High tech fields: entering the semiconductor, new energy, and aerospace industriesWith technological iteration, silicon carbide has entered the high value-added industry chain. In semiconductor manufacturing, its high rigidity, low thermal expansion, and corrosion resistance make it suitable for precision components such as wafer transfer and etching chambers; In the fields of new energy such as photovoltaics and lithium batteries, silicon carbide materials help improve energy conversion efficiency and equipment stability; In fields such as aerospace and nuclear energy, its lightweight, high strength, and high temperature resistance make it an ideal choice for engine components and thermal protection systems.Future Trends: Material Optimization, Cost Reduction, and Sustainable RecyclingFaced with the growing market demand, the silicon carbide industry is developing in three directions: first, through process improvement and large-scale production, further reducing costs; Secondly, conduct research on material modification to improve its brittleness and processability; Thirdly, we will continue to expand our applications in emerging fields such as communication, electric vehicles, and national defense. Meanwhile, driven by the concepts of green manufacturing and circular economy, environmentally friendly silicon carbide products and their recycling technologies will also become a key issue for the sustainable development of the industry.

Silicon carbide (SiC) products, including black silicon carbide and green silicon carbide, are playing an increasingly critical role in high-tech fields such as semiconductors, new energy, and aerospace due to their excellent performance as a refractory material. This compound composed of silicon and carbon has become an irreplaceable material in many extreme environments due to its ultra-high hardness close to diamond, stability to withstand ultra-high temperatures and strong corrosion, and excellent thermal conductivity.Super performance: Hardness comparable to diamond, heat resistance up to 2700 ° CThe hardness of silicon carbide exceeds Mohs 9, and its wear resistance is more than ten times that of alloy steel. At the same time, its melting point exceeds 2700 ° C, and it can work stably for a long time at 1600 ° C. Its high thermal conductivity (over 12W/m · K) also makes it an ideal choice for high-temperature heat dissipation scenarios. Production challenge: High hardness accompanied by high brittleness, process difficulty drives up costsThe preparation of silicon carbide products relies on high-temperature sintering or hot pressing technology, which requires precise control of temperature, pressure, and time to ensure material density. However, its extremely high hardness also brings significant processing difficulties - cracks are prone to occur in fine machining, which places strict requirements on equipment and processes, resulting in high production costs and long production cycles.Widely applicable: from semiconductors to aerospace, playing a key role in multiple fieldsAt present, silicon carbide has been widely used in the fields of electronic control systems for new energy vehicles, photovoltaic inverters, 5G communication base station heat dissipation components, high-end wear-resistant devices, and aerospace high-temperature resistant components, helping equipment operate stably in efficient, high-temperature, and highly corrosive environments.Future prospects: Technological breakthroughs drive application expansionWith the continuous optimization of preparation processes and advances in processing technology, the cost of silicon carbide products is expected to gradually decrease, and its penetration rate in clean energy, electronic information, and defense technology fields will further increase, becoming one of the key materials supporting industrial upgrading.
