Product Detail


In order to remove hydrogen in the aluminum liquid, silicon nitride hollow degassing rotor is used to feed nitrogen or argon, and the gas is dispersed by high-speed agitation, and finally achieve the effect of neutralizing and discharging hydrogen.

 

Compared with graphite rotor, silicon nitride rotor will not be oxidized under high temperature environment. So it will not contaminate aluminum liquid, and will definitely improve the purity of aluminum liquid.

 

The property of high thermal shock resistance ensures that silicon nitride degassing rotor will not break during frequent intermittent operation.

 

Because of its high density, high strength and excellent resistance to high temperature, silicon nitride degassing rotor can still maintain good performance in high-speed rotation under 1200° high temperature environment.

 

The normal use of silicon nitride degassing rotor is ten times the life of graphite. Silicon nitride degassing rotor has its non-wetting properties and is resistant to various acid and alkali corrosion. It greatly reduce slag adhesion during operation. So the time cost loss caused by replacement of spare parts or cleaning of aluminum slag is greatly reduced, which improve industrial production efficiency and reduce material consumption.

 

Our company's patented degassing rotor is designed specifically for the degassing process of liquid aluminum, and specifically designed degassing rotors of full silicon nitride structure that can crush bubbles in the aluminum liquid six times.

 

To reduce costs and increase revenue, products can be customized according to the needs of customers’ specific application or designed by our company.
