REFRACTORY USED FOR PRODUCING MOLTEN PIG IRON AND MOLTEN STEEL

摘要

PROBLEM TO BE SOLVED: To obtain a refractory capable of raising the strength of a refractory by making a platy aggregate always present in the refractory and suppressing the erosion or spalling and used for producing the molten pig iron and molten steel. SOLUTION: This refractory is obtained by adding 4-50 wt.% of a platy aggregate 11 having 2.5 and <=60 mm longest side and >2 and <=8 mm thickness to a refractory raw material 12.
