Product Description

3 Phase SiC Rod Heating Element For Glass furnace 1550℃

Silicon carbide rod heating element is a kind of non-metal rod or tube shape high temperature electric heating element. It is made of selected super purity green hexagonal silicon carbide as main material, which is made into blank and silicon crystal under high temperature of 2400ºC. In oxidizing atmosphere, its service temperature can reach 1450°C and continuous use life can reach 2000 hours.

Types: U, W, H, Gun, H, Single Spiral, Double Spiral, Dumbbell, Door like and other irregular shapes
