Wide Application of Lightweight Castable Refractory
Depending on the working conditions, you can choose whether to contact fire:
As thermal insulation lining: linings of kilns, thermal equipment, flues and smoke windows in the metal, machinery, petrochemical, power and building materials industries
As working linings that directly contact the flame: waste incinerator, circulating fluidized bed boiler, petrochemical industry heating furnaces, ethylene cracking furnaces, hydrogen production conversion furnaces, heating furnace convection sections, flues and other equipment. Do not contact with the melt or solid medium in the furnace for a long time. Visit more details on Kerui Pinterest.
Advantages about Insulating Castable Refractory
Strong Operability
The initial setting time and operability time of lightweight castable are longer. Because this product has good fluidity. Workers can ensure that the masonry mortar joints are dense and full.
Energy saving
The pores of lightweight castable can effectively store heat to save fuel consumption. In addition, this product has good sealing properties, which can effectively improve the performance of the kiln.
Extend the Service Life
Lightweight castable is an excellent furnace lining, which can effectively reduce the load and overall pressure of the kiln. In addition, during the operation of the kiln, the temperature changes frequently, and lightweight castable can better adapt to these changes and reduce cracks and spalling caused by thermal shock.
