As a kind of high alumina refractory brick, mullite brick can be used in a wide range. What are the main applications of mullite brick?
Mullite brick is a refractory brick with mullite as the main crystal phase. It has high load softening temperature, low high temperature creep rate, good thermal shock resistance, and strong acid slag erosion resistance. Mullite bricks are based on the application industry. Classification mainly includes the following aspects:
1. Ironmaking industry
Mullite bricks are used in the suspension and orifices of hot blast pipes of hot blast stoves, pipe standpipes and straight pipes with higher temperature, onlookers and temperature stable parts. The grades of mullite bricks used in different areas are different; the parts of torpedo tankers that are impacted by molten iron , Slag line area.
2. Glass ceramic industry
Mullite bricks are used in the main material channel of glass kilns, regenerators, and clarification tank walls; mullite bricks are used to make saggers and kiln furniture in ceramic industrial kilns.
3. Building materials industry
Mullite bricks can be used for the lining of cement and lime rotary kilns.
According to different bulk density, mullite bricks are divided into light mullite bricks and heavy mullite bricks. The main applications of light mullite bricks are: the partition of industrial kilns in metallurgy, petrochemical, building materials, ceramics and other industries. Thermal layer, such as heating furnace, soaking furnace, heat treatment furnace, tunnel kiln, roller kiln, shuttle kiln, etc.
Mullite bricks have a wide range of applications, but the choice of refractory bricks for industrial kilns still has to meet the needs of the kiln. Secondly, the economic benefits are considered, and the selection of mullite bricks is comprehensively considered.
