Intermediate frequency furnace usage rate

Xiaobian will give you a brief introduction.To improve the utilization rate, the following points should be done: 1. Selected materials with high purity (SiO2 content> 98%), no iron, polygonal or round sand grains, and moderate particle size; 2. Fine knotting and reasonable ratio , so that the density of the knotted furnace lining can reach 2kg/m3, the knots are uniform, and layering and sparseness are not allowed; 3. Careful use, the temperature should be raised slowly during the oven, and the phase change process should have sufficient holding time. Make sure the phase transition is sufficient.In the first furnace smelting, a high temperature holding stage is required to form a complete inner wall sintering layer.When adding materials, it is necessary to prevent the furnace wall and shed from being damaged.During heat preservation, the slag is prevented from being crusted and sealed. When the melt in the furnace is less than half of the furnace, low-voltage power supply is required for heat preservation.When the furnace is shut down, cover the furnace mouth and slowly cool down.When restarting, refill in small batches and slowly heat up.If the furnace is repaired using the cold patching method, attention should be paid to hidden dangers, the slag layer should be removed, and the knots should be finely knotted.Tangshan Fengrun District Baojun Power Equipment Manufacturing Factory tsbjdy.cn
