Magnesia spray coating for EAF/ converter
Used for spraying repair of slag line or impact area, after 5 min sintering, the spraying layer has the following characteristic: highadhesion strength, low resilience, easy sintering and corrosion resistance. it can prolong the service life of the electric furnace , improve the work efficiency of electric furnace and reduce the maintenance time of the furnace.
Sag stopping plug for converter
In the process of converter steelmaking , the oxidizing slag produced per ton of steel is about l0o kg l50 kg. The slag stoppingplug produced by FUHAO Can effectively remave slag , ensure the quality of molten steel and prolong the service life of taphole andladle.
