Refractorybrick in the production process cannot do without the help of the size and quality of mold, mold determines the quality of refractory brick molding, the following is the principle of making refractory brick shaping mould:

1, the form must be smooth surface, smooth, and have higher hardness.

2, installation of formwork should taper, under the mouth small, big, catchy symmetry, and to ensure that qualified size refractory brick. Taper model after installation is generally 5/1000.

3, uneven surface should be made into a hopper.

4, as far as possible to make the maximum area of the refractory brick as the compression face.

Ditch edge at 5, within the model with radian, template at a corner with L - 2 mm arc.

6, in the event of a mould bottom protruding part, try to make the survival of wedge.

7, the scaling length ratio. The general is according to different kind of brick and clay, is determined by the actual test. At present, China's production of brick, scaling rate is generally 3-4%; length ratio put clay brick for 1-2.5%.

8, thick skin: refractory brick more than 150 mm, should consider two pressures.

Through the above simple introduction I hope can help to you, we produced the high quality and low price firebrick , please contact us if you have the need.
