CH refractories series high grade and middle grade non-baking ladle shroud has the advantages of good thermal shock resistance, strong steel erosion resistance, good slag resistance, etc.
The ladle shroud is a refractory material which connects the steel ladle with the tundish. The ladle shroud has the functions of stabilizing the flow state of liquid steel, preventing liquid steel from oxygenation and splashing. CH refractories series high grade and middle grade non-baking ladle shroud has the advantages of good thermal shock resistance, strong steel erosion resistance, good slag resistance, etc. What's more, ladle shroud has been rapidly promoted due to its characteristics of convenient operation and improved operating conditions substantially.
