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.
Advantages:
High density, high strength, high purity, excellent erosion resistance to molten steel and high temperature resistance.
