refractory

Refractory material has many molding methods, in addition to compression molding, including vibration molding, compaction molding, plastic molding, slip casting molding, casting molding, hot pressing and hot die-casting molding.

1. Vibration molding

Vibration molding is to use mud material under the action of vibration, dynamic friction instead of static friction, mud slurry and slurry material greatly reduce the friction between the mold wall, the sludge particles have good fluidity filled mold parts. At the same time, small particles can be filled into the gap of larger particles in order to achieve the purpose of density.

2. Compaction molding

Compaction molding is the use of hammer compaction mud material, to obtain a certain shape and density of the molding method. Tamping machine is usually pneumatic or electric drive, can also be manually compacted. When playing, the sludge is added to the layered model, which in turn will be wrapped on each floor. Crushing method for semi-dry sludge production of different products. The method of labor intensity, noise is also large.

3. Plastic molding

Plastic molding is a good plastic clay into the model or extrusion molding extrusion molding method. Plastic slurry containing high water content, the mass fraction is usually more than 15%. In the refractory industry, it is usually used in the manufacture of rough, more for mullite, bauxite clinker and other raw materials production.
