High Quality Ceramic Fiber side feed nozzle For casting machine
Ceramic Fiber side feed nozzle are the key parts of the continuous aluminum trip casting machine which directly effect the quality of aluminum sheets. The tips for casting can be divided into many types according to different casting machines. Ceramic Fiber side feed nozzle produced by our plant is compounded by ceramic fiber and some other refractory materials. The opening surface and the coating of the working surface are smooth and it can resistant to the corrosion of the liquid aluminum , guarantee the purity of the aluminum sheet .
Ceramic Fiber side feed nozzle with excellent non-wetting properties, low thermal conductivity, high temperature stabilities, uniform density, smooth surfaces and close tolerance, is superior products for continuous aluminium strip casting.
