Refractory materials have many forming methods, in addition to pressure molding method, contain the vibration forming, ramming forming, plastic forming, slip casting forming,
casting forming, hot press forming and hot die casting forming, etc.
1. Vibration forming
Vibration forming is to use the mud material under the action of vibration, dynamical friction instead of static friction, inner mud material and mud material greatly reduce the
friction between the die wall, sludge particles have good liquidity to fill the mould parts. At the same time, small particles can fill into the gap of the larger particles to reach the
purpose of the density.
2. Ramming forming
Ramming forming is to use hammer to compact mud materials, in order to make it obtain a certain shape and density of molding method. Rammer commonly used pneumatic or
electric drive, can also be artificial compacted. When playing, adding sludge in layered model, in turn play will be packed on each floor. Ramming method is suitable for the half-dry
sludge to produce big different products. The method of the intensity of labor is larger, the noise is also bigger.
3. Plastic forming
Plastic forming is to put good plasticity mud materials into model molding or by squeezing machine extrusion molding method. Plastic mud materials contain high water, mass
fraction is usually above 15%. In refractory industry, it is commonly used to make blank, more used in mullite, bauxite clinker and other raw materials production.
4. slip casting forming
Slip casting forming is after plaster mold absorbing water slurry solidifying to obtain green body. In order to get the hollow products, after part of the slurry curing, pouring out the
central part of the solidified mud dehydration. In order to improve the quality of grouting speed and green body quality, can take the pressure grouting, centrifugal grouting
casting forming, hot press forming and hot die casting forming, etc.
