北单比分zhibo:Measures to solve the difficulty of high alumina refractory bricks
When we are in the production of high-alumina refractory bricks, we all know that after years of production experience, we have summarized some difficult integrations in the production of ingredients, understand these, we are in production There will be fewer detours.
1. In its current production, the semi-dry pressing method is generally adopted, which requires that the blank of the paving brick should have sufficient bonding, so the binding component should be contained in the ingredients;
2. The chemical composition of high-aluminum refractory bricks must meet the requirements of its professional requirements, and should be higher than the requirements of paving slabs. In the chemical composition, it includes the content of main components of paving slabs, the total amount of fusible impurities and harmful impurities. Provision of the amount of permission;
3, high alumina refractory brick raw materials contain ingredients and discretionary ingredients, so that there is a conversion relationship between raw materials, ingredients and chemical composition.
