Solutions to steel leakage between upper and lower slide gate plate
1.The "tongue damage" produced by the surface of lower slide gate plate causes the steel to be clamped, and causing steel leakage.
2. An annular cold steel ring is generated around the "filling hole" of the slide gate plate to cause steel leakage.
Combine the smelting conditions to improve the quality of the slide gate plate. Improve its anti-oxidation and erosion resistance. At the same time, reasonably mix the composition of the filling hole and its surrounding refractory materials
, and increase the firing temperature of the slide gate plate to reduce the relative shrinkage of the filling hole material and its surrounding materials during the steel casting process.
