Refractory Brick's forming 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 development does not need basically external forces.
The molding of refractory brick, firstly is to satisfy the using demand of the products, when refractory brick masonry, the requirement of products must have a certain shape, precise
size, and enough strength. Secondly, molding is also the efficient way to improve the physical and chemical properties of products, by shape can improve the organizational
structure of products. Refractory Brick has a lot of forming ways, the traditional processing ways according to how much moisture content can be divided into:
1. Semi-dry way: its blank moisture is around 5%, suitable for blank of different clinker content(50% 100%).
2. Plastic way: its blank moisture is around 15%, suitable for manufacturing large or complicated shape of the products.
3. Grouting way: its blank moisture is around 40%, is suitable for all kinds of hollow thin-walled refractory materials in production.
The modeling ways of refractory brick have a lot, the common used forming ways contain organic pressure forming, vibration forming, extrusion forming, ramming forming,
isostatic pressure forming, casting forming, grouting, etc.
Choose what kind of forming way, mainly according to the nature of the plaster, body shape, size and other technical requirements. In addition to most of the refractory brick is
made of machine pressure forming, vibratory forming is used for special-shaped body, the extrusion forming is generally used in tubular blank, slip casting forming is used for
thin wall body shape.
