How many types of the bonding methods about refractory casta

How many types of the bonding methods about refractory castable binder? Refractory castables can be combined in the following ways: 1. Hydration binding – binding occurs by means of hydration reaction between binder and water at room temperature to produce hydration products. 2. Chemical bonding takes place by means of a chemical reaction between a…

How is the graphitization achieved in graphite electrode pro

How is the graphitization achieved in graphite electrode production? Graphitized carbon materials are carried out at a high temperature of 2200 ~ 3000 ℃, so the industry can only be achieved by electric heating, generally resistance heating or induction heating. In resistance heating furnaces, Acheson graphitization furnaces, directly energized internal heat tandem (LWG) graphitization furnaces…
