Silica Bricks Manufacturing Process. Silica bricks are made of silica rock with SiO2 content more than 96%, combining iron sale or lime milk mineralizer and molasses, lignosulfite binder. The silica bricks are formed through the process of mixing, molding, drying and firing thereafter. The most harmful impurities in the silica bricks manufacturing process are Al2O3, K2O, Na2O and so on, which seriously reduce the degree of refractoriness of refractory

Refractory manufacturing involves four processes: raw material processing, forming, firing, and final processing. Figure 11.5-1 illustrates the refractory manufacturing process. Raw material processing consists of crushing and grinding raw materials, followed if necessary by size classification and raw materials calcining and drying. The processed raw material then may be dry-mixed with

Silica refractory brick belongs to acid refractory material and has strong resistance to acid slag erosion and oxides of CaO, FeO and Fe2O3. But silica fire brick is easily damaged by Al2O3 oxide when eroded strongly by alkali slag. Expansibility Silica refractory bricks’ thermal conductivity and bulk increases with the service temperature rising. There is no linear after contraction during the baking process. During the baking process,

HTL can optimize the heat treatment process for the production of refractory materials. This in particular concerns shaped refractory products which are produced via the powder route. Starting from drying of the green bodies through binder burnout or pyrolysis up to the sintering process, efficient methods for the identification of optimal process parameters are available for all heat treatment steps. The basis for the process

03/02/2015 The majority of refractory bricks are normally produced by the extrusion process. The soft mud or plastic moulding process is particularly suitable for refractory mix containing too much water to be extruded by the stiff mud process. Refractory mixes are mixed to contain 20 % to 30 % of water and then formed into shapes in molds.
