Description

technical field

[0001] The invention relates to the field of iron trench castables, in particular to a method for preparing iron trench castables containing graphene oxide. Background technique

[0002] The blast furnace iron trough is a channel for guiding high-temperature molten iron and slag, and its refractory lining is subjected to high temperature, mechanical and chemical erosion of molten iron and slag. With the development of large-scale blast furnace smelting technology, the temperature of molten iron is higher, the amount of iron passing is increased, the time of iron passing is prolonged, the interval between tapping iron is shortened, and the oxidation of slag and iron is enhanced, which makes the high temperature molten iron and slag scouring and wearing the refractory Increase, which puts forward more stringent requirements on the erosion resistance, thermal shock resistance, burst resistance and erosion resistance of refractory materials.
