Abstract：According to the requirements of a steel rolling mill,Shannai Wanglv developed a kind of self-flow fast-drying explosion-proof castable for water-cooled beams,which is prepared by taking high alumina bauxite clinker as the main raw material,calcium aluminate cement as the binding agent,and the substrate is introduced with high-quality alumina micropowder and silica micropowder.The effects of different particle size gradation,different grades and amount of silica micropowder,cement and alumina micropowder on the fluidity,flexural compressive strength and post-firing line change of this castable were analyzed.According to the test results and customers'demands,Shannai Wanglv preferred ZKF-6 castable formula from the comprehensive consideration of water addition,fluidity,strength,anti-explosion performance,solidification time and post-burning line change,and the castable for water-cooled pipe of steel rolling furnace has been put into use in a rolling mill,which fully meets the production requirements.
