How does the induction melting furnace melt?
1. If the molten steel remaining in the furnace of the induction melting furnace is greater than 3t, after charging, the power can be adjusted to the maximum allowable power load after power transmission; if there is no molten steel remaining in the furnace or the remaining steel volume is less than 3t, load ingots or others After a large piece of heavy material, the power should be gradually increased at a certain time interval, and it is strictly forbidden to adjust the power to the maximum allowable load within the first 10-15 minutes.
2. During the power supply process of the induction melting furnace, the furnace condition should be observed at any time. When bridging or material stacking occurs, it should be handled in time to avoid accidents caused by excessively high temperature of the molten steel at the bottom, and to avoid waste of power consumption.
3. In order to prevent the exposed molten steel from being oxidized by the air, during the melting process, a certain amount of pre-melted synthetic slag is added to the part where the molten pool is formed (or exposed to the molten steel), and the total amount added to each furnace is controlled at 10-20kg. After cleaning, the power should be appropriately reduced, and 1-2 bags of covering agent should be added at the same time.
4. After confirming that the steel ingots or the returned raw materials in the furnace are all melted, perform temperature measurement. Except for confirming the molten alloy, the temperature can reach 1600℃ before sampling. Before sampling, the laboratory should be notified of the type of returned materials in the furnace and quantity. After the ingredients are determined, the refining section and scheduling must be notified immediately.
5. During the melting process, it is necessary to observe whether the liquid level in the furnace has crusts at any time, especially in the upper low temperature area. If crusts are found, immediately power off for treatment to avoid accidents.
