Molding and Methods of Refractory Material

Writer:Mr. Roger SunNumber of visits: Date:2/8/2017

Refractory bricks molding in the manufacturing process , refers to the refractory raw materials recuring to outside force and the model, making the blank will be processed into specified dimension and shape. However, the flow castable's construction of the latest devlopment does not need basically external forces.

The molding of fused cast AZS, firstly is to satisfy the using demand of the products, when refractory brick mansonry , the requirement of products must have a certain shape,precise size , and enough strength. Secondly, molding is also the efficient way to improve the pyhysical and chemical properties of products , by shape can improve the organizational structure of products. Refractory brick has a lot of molding methods , the traditional processing methods according to hou much moisture content can be divided into :

1.Semi-dry method:its blank moisture is around 5% ,suitable for blank of different clinker content ( 50% - 100% ).

2.Plastic method: its blank moisture is around 15% , suitable for manufacturing large or complicated shape of the products.

3.Grouting method: its blank moisture is around 40% , is suitable for all kinds of hollow thin-walled refractory materials in production.

The modeling methods of refractory brick have a lot,the common used molding ways contain prganic pressure molding , vibration molding , extrsuin molding , ramming forming , isostatic pressure molding , casting molding , grouting , etc.
