Quick repair material for the tap hole of the converter

With sintered magnesia and synthetic magnesia as the main raw materials, modified powdered asphalt and phenolic resin as binders, nitronaphthalene as glidant, and appropriate amount of wetting agent, a large-surface repairing converter has been developed. material. The test results show that the repair material has good high-temperature fluidity, fast automatic leveling, short hardening time, high bonding strength, long service life, and low environmental pollution.
