A blast furnace is a vertical furnace used for iron making. From top to down a blast furnace is divided into throat, upper stack, middle stack, lower stack, belly, bosh, hearth and bottom. Different part of blast furnace features different nature of refractory lining wearing. As to throat and upper stack, for instance, the abrasion of the incoming burden makes the main contribution to wearing. While in area such as lower stack, belly and hearth of blast furnace, where temperature is significant higher, chemical corrosion of alkali, zinc vapor, molten iron and slag become the main wearing factors. 
Yanmu provides a complete product series of shaped and unshaped refractory products for blast furnace, which are carefully engineered to fit various operation circumstance inside the furnace, in order to extend the campaign life of blast furnace in an economic way. 
We are ready to provide our know-how and consultation service regarding refractory material design for the whole blast furnace.
