Three types of binding agents commonly used in refractory castables

Refractory castable is composed of refractory aggregate and matrix powder, adding a certain amount of binding agent and additives together. At the time of construction, water is added for mixing to make it have good fluidity, and further after molding and maintenance to make it coagulate and harden. Because of its high construction efficiency, simple […]

How to distinguish between graphite recarburizer and coal recarburizer

Different recarburizers have different qualities. For example, there are graphite recarburizers and coal-based recarburizers. Although they are all recarburizers, they are different in basic characteristics, absorption coefficients, prices, advantages and disadvantages, etc. It is not very large, but if it is not used properly, it will also affect their recarburization effect. 1.The raw materials of
