INSULATING MATERIAL FOR MOLTEN STEEL SURFACE

Title:

INSULATING MATERIAL FOR MOLTEN STEEL SURFACE

Document Type and Number:

Japanese Patent JPH0833960

Kind Code:

A

Abstract:

PURPOSE: To provide an insulating material which surely prevents contamination of molten steel occurring due to air oxidation and the reaction of insulating material and has a sufficient insulating function without damaging and eroding refractories.

CONSTITUTION: This insulating material for molten steel surface is formed by incorporating hollow sintered compacts, having the content of CaO and Al2O3 below 0.5 or over 2.0 by CaO/Al2O3 by 5 to 90wt.%, into the liquid phase insulating material which is specified in the content of CaO and Al2O3 to 0.5 to 1.0% by CaO/Al2O3, the content of MgO to ≥5 to <30% and the content of SiO2 to ≤10%.
