Refractory fire assay clay crucible refers to the refractories greater than 1580℃, can be used as refractory clay and bauxite used as refractory. In addition to their high refractoriness, they can maintain volume stability under high temperature conditions, and have slag resistance, resistance to cold and heat, and a certain mechanical strength, so they are unusually firm after calcination. Refractory clay is mainly used in the metallurgical industry, as a raw material for the production of shaped refractories (bricks of various specifications) and non-shaped refractories, the amount of which accounts for about 70% of all refractories.
How to make a crucible A crucible is a tool used to smelt metal, glass and other substances. Its making method can be simply divided into the following steps: selecting materials, making a crucible mold, making the crucible body, and firing the crucible. The production method of each step will be introduced in detail below. Selecting materials is the first step in making a crucible. Commonly used crucible materials include ceramics, graphite and quartz. Ceramic crucibles are suitable for low-temperature melting, while graphite crucibles are suitable for high-temperature melting. Choose appropriate materials according to actual needs. The second step is to make the crucible mold. The crucible mold is used to make the shape of the crucible. Commonly used materials include gypsum, sand, etc. First, design the shape of the crucible, and then make the mold according to the design. When making the mold, attention should be paid to ensuring the accuracy and smoothness of the mold to facilitate subsequent
