Insulating charging hole cover |
摘要 |
A coke oven charging hole cover which includes a cylindrical wall section and a lower horizontal layer of a cast-in-place castable refractory material which is relatively dense and which contains a random dispersion of fine stainless steel fibers or similar fibers. A layer of an insulating material such as insulation board or a lightweight castable insulating refractory material is superimposed over the dense refractory material to enhance the overall insulating effect while avoiding damage due to carbon impregnation. A means for holding the refractory in the wall section such as a wire mesh which is fixed to the wall section and cast into the lower layer of the refractory is also provided.
