Firebrick production process, raw material selection, powder preparation (crushing, crushing, screening) - ingredients, mixing proportion, blocking molding, drying, sintering, inspection, packaging.

1 Ingredients

Each batch of raw materials into the factory need to issue a product quality guarantee, at the same time in accordance with the quality guarantee on the index of three sampling tests: index test, physical and chemical performance test, refiring furnace firing test, qualified before the production can be put into production, must be pickling, iron absorption secondary finishing treatment, so that the quality of raw materials to achieve the production of products in a better state.

2. Mix and train

The raw material preparation personnel shall prepare the raw material in strict accordance with the requirements of the technical department. In the preparation process, it is necessary to accurately weigh and mix on time. The specific operation is: less than 100 mesh fine powder needs to be premixed first, and through 24 mesh sieve twice, the binder needs to be soaked for more than 24 hours, the cumulative mixing time should not be less than 20 minutes, and it is necessary to use the same material on the same day, so as to avoid residual mixing, and to achieve on-site sanitation and cleaning to ensure the purity of raw materials.

3, molding and inspection in the molding process to take what forming means to formulate according to the structure of the product, but no matter what kind of molding means, in the mold installation process pay special attention to the structure of the product, in the molding process of the front block of the semi-finished product must be inspected before the production can continue. And in all semi-finished products on the product model, net weight and production date, the logo should be clear, in order to carry out quality follow-up inspection, while the operator must do self-inspection, self-pick, take the initiative to eliminate waste and defective products, can not be shoddy, quality inspectors should be in accordance with the drawing size one by one check to ensure that the size is correct, At the same time, the semi-finished products should be inspected whether there are lamination, porosity, segregation, cave, incomplete corners and other phenomena, find problems, timely solution, to ensure the yield of semi-finished products, after passing the inspection, by the biotechnical Department with a re-burning furnace test refractory sample brick, can be dried after passing the test, under the premise of ensuring quality, and must ensure the production schedule, in order to deliver on time.
