Spread in outer working face corundum castable fragment of brick, and the sealing of spray refractory powder.
Nozzle is connected using internal thread with supply lower branch line.
Above-mentioned technical proposal of the present utility model has the beneficial effect that：
In such scheme, compared with prior art, it is not necessary to just change entirety when the resistance to material of tedge has been damaged, but
A part for damage can be selectively changed, resistance to aptitude source can be significantly saved, non-damageable rising is improved
The service life of pipe top half, and substitute mode is simply effective.Simultaneously solve current RH refinings exist it is exposed
The problem that steam line is easily damaged by high-temperature molten steel splash.
