What is the production process of ladle magnesia carbon brick?

Ladle magnesium-carbon brick is generally non-fired refractory brick, the production process mainly includes: batching, mixing, molding, heat treatment. Amorphous refractory

1, the batching is the first process of making magnesia-carbon bricks, and the raw materials of magnesia-carbon bricks are proported in strict accordance with the formula requirements.

2, the mixing process is to affect the quality of magnesia carbon brick and finished magnesia carbon brick, mixing, first add no coarse particles, medium particles into the mixing, and then add the binder low speed mixing, so that aggregate and binder fully uniform, and then add graphite high speed mixing to aggregate, graphite and binder fully uniform, and then add magnesia fine powder, additives and so on to continue mixing. When the graphite and magnesia particles are fully mixed with fine powder and additives, the mixing ends.

3, magnesia carbon brick forming need to use a high pressure press by high pressure pressing, so that magnesia carbon brick brick density is greater, to ensure that magnesia carbon brick has high volume density and low apparent porosity, strict control of the weight of a single brick.

4, brick heat treatment first put the brick at room temperature 5-6 hours, so that it fully volatilized. Then the heat treatment is carried out at 150℃-200℃, the time is not less than 32 hours, and the room temperature is less than 80℃, the time is not less than 16 hours.
