Taphole Blocks is a high-performance refractory block that lines the tapping hole of a metallurgical furnace (like a blast furnace or submerged arc furnace).
It forms the durable channel for tapping molten metal and slag.
Raw Materials:
Manufactured from high purity, low-silicon, high calcium fused magnesia, combined with large flake high purity graphite.
Adding various additives like metal and boride, bonded with phenolic resin.
High density, high strength, high purity, excellent erosion resistance to molten steel and high temperature resistance.
