Silicon carbide beams and rollers are used as loading frames in porcelain producing kilns, and which can replace normal oxide bonded silicon plate and mullite post as they have good advantages like save spaces, fuel, energy and also short the firing time, and the life time of this materials is several times of others it is very ideal kiln furniture. Silicon carbide beam is mainly used as the load carrying members of tunnel kiln, shuttle kiln and double channels kiln. It can also be used as the kiln furniture in ceramic and refractory industry. RBSiC (SiSiC) has excellent thermal conductivity, so it is available to save energy with less weight of the kiln car. Beams with high - temperature bearing capacity of large, long-term use without bending deformation, especially suitable for tunnel kilns, shuttle kiln, in two - layer roller kiln and other industrial furnace load - bearing structure of frame. Clubs apply to daily - used ceramics, sanitary porcelain, Building Ceramic, Magnetic material and high temperature firing zone of roller kiln.
