How to solve the lining problem of crucible induction melting furnaces

This Video shows the process of how to make the lining for the crucible induction melting furnaces. Let me introduce the step how to do it. 1. Spread the asbestos cloth. 2. Knotting the bottom of the furnace, usually the height of the first layer of the crucible bottom is about 80-100mm, and each subsequent layer is 40-50mm, and the final layer should be 20-30mm higher than the bottom of the furnace. , Do not pile up, so as not to separate the size particles of the material. To avoid delamination, use a cutting fork to break up and smooth the freshly knotted surface layer before each addition. Knotting should be hammered vertically, not swinging from side to side. At the same time, pay attention not to damage the heat insulation layer when knotting. When knotting, it should be light first and then heavy. 3. The order of knotting is the edge first and then the center, and knots are tied row by row in order. Shovel off the excess after hitting with a flat hammer, and keep the bottom of the furnace leve
