What is the difference between refractory castable and refractory cement? For customers who do not know about refractory castable and refractory cement, these two different products may be confused, especially foreign customers. Today we are talking about refractory castable and refractory cement. What kind of products are introduced to facilitate you to better understand and purchase refractory castables and refractory cement.
Refractory castable is a kind of unshaped refractory. It is made by mixing and mixing refractory aggregates, powders, binders and admixtures. The refractory castables are made of different aggregates and binders. The functions are also different. There are many types of refractory castables, and the corresponding castables can be selected for lining according to the environment of the industrial kiln.
When RongSheng castable manufacturers produce refractory castables, they usually recommend reasonable refractory castables according to the refractory castable index provided by the customer or according to the industrial kiln environment provided by the customer and customize the processing to ensure high quality and meet industrial requirements. The use requirements of the kiln.
Refractory castables are usually used as kiln integral lining products. During on-site construction, the castables and binders need to be pre-mixed, then appropriate water is added, and then poured into the installed lining mold after uniform mixing. The vibrating rod is formed by vibration and can be put into use after curing, demoulding and baking.
Refractory cement is a kind of refractory material used as a binder and refractory powder when making refractory castables. It uses high-quality bauxite and lime as raw materials and mixes it into a certain proportion of raw materials. After sintering, it is obtained as aluminate The clinker, which is the main component, is then ground into fine powder to produce a fire-resistant hydraulic cementitious material called refractory cement. Refractory cement is divided into aluminate cement, dolomite cement, calcium magnesium aluminate cement, etc. according to the different components.
Refractory cement is different from common ordinary cement. Refractory cement is used as a binder for refractory castables under high temperature conditions. It has good binding properties and will not affect the high temperature performance of refractory castables. Refractory cement has the characteristics of fast hardening speed, high bonding strength, strong plasticity and convenient construction.
Through the above introduction, we know that refractory castable is a kind of refractory product, which is used in the lining of industrial kilns, and refractory cement is used as a binder or refractory powder when making refractory castable, which can make the castable Quickly combine and promote coagulation.
