Silicon carbide RBSIC ceramic tube burner nozzle / burner pipe for gas tube furnace
with the features of high temperature resistance,extreme cold and heat resistance,long service life,no cracking and easy to process into various shapes,it is an ideal fire kiln furniture for tunnel kiln,shuttle kiln and roller kiln, also widely used in industrial furnaces with direct fire heating and radiant tube indirect heating system. Silicon carbide burner nozzle is an ideal combustion chamber for various industrial furnaces such as gas and fuel furnaces.Reaction sintering silicon carbide burner nozzle is composed of α-SIC powder, graphite powder,mixed additives and organic binders,and sintering in a 1700 degree vacuum furnace to fully react the silicon carbide powder with carbon.The final porosity is almost 0,in particular, some customers' burning substances are kerosene, diesel, etc.Low porosity can prevent oil leakage,our silicon carbide burner nozzle have helped many customers solve the problem.
