Casting yard-iron trench

Hefeng Company provides iron ditch aluminum silicon carbide carbon castables, iron ditch preforms and gunning materials, hot repair materials and other products used in iron casting yards.

Tiegou aluminum silicon carbide carbon castables are made of dense corundum, brown corundum, silicon carbide, high-purity calcium aluminate cement, asphalt and other raw materials. Using ultra-low cement bonding technology, it has good thermal shock resistance and erosion resistance. Convenient for on-site pouring and molding, suitable for large blast furnace tapping plants. The iron ditch preform made of ASC low-cement refractory castable has good erosion resistance, high temperature resistance, and thermal shock resistance in the use of the tap ditch, and can effectively resist the corrosion of molten iron and molten slag.

Hefeng company adopts ASC series of materials to develop and produce blast furnace taphole gunning materials, which have high adhesion rate, high bonding strength, slag erosion resistance, peeling resistance and thermal shock resistance. The semi-dry gunning method has the advantages of cold and hot construction, suitable for rapid baking, and repairing can be completed in the gap between two taps, which can effectively extend the service life of the main ditch of the blast furnace and reduce refractory materials per ton Consumption. The iron trench quick repair material made of aluminum silicon carbide carbon has good slag erosion resistance, spalling resistance and thermal shock resistance. It has the advantages of hot construction, adapting to rapid baking, and repairing in the gap between two taps, which can effectively extend the service life of the main ditch of the blast furnace and reduce the consumption of refractory materials per ton of iron.
