内容简介

The lining of blast furnace may be damaged partly, so that gunning repair is needed. The bonding strength of boundary surface between the repairing layer and remained lining of blast furnace has been studied by thermal simulation. The factors influencing the bonding strength are the ingredient gunning repair temperature, remained lining condition and water content of gunning refractory. The bonding strength decreases with the increases of remained lining temperature.
