Hot metal leaking from induction melting furnace
Hot metal leaking from induction melting furnace
Liquid iron leakage accidents can easily cause equipment damage and even endanger humans. Therefore, it is necessary to do the maintenance and maintenance of the furnace as much as possible to avoid liquid iron leakage accidents.
(1) When the alarm bell of the furnace lining thickness measuring device rings, the power supply should be cut off immediately, and the surroundings of the furnace body should be inspected to check whether the molten iron leaks. If there is any leakage, dump the furnace immediately and finish pouring the molten iron.
(2) If the molten iron has been found, evacuate the personnel immediately and pour the molten iron directly into the pit in front of the furnace;
(3) The molten iron leakage is caused by the destruction of the furnace lining. The smaller the thickness of the furnace lining, the higher the electrical efficiency and the faster the melting speed. However, when the thickness of the furnace lining is less than 65mm after wear, the entire thickness of the furnace lining is almost always a hard sintered layer and a very thin transition layer. There is no loose layer, and small cracks will occur when the lining is slightly subjected to rapid cooling and heating. The crack can penetrate the entire furnace lining and easily cause the molten iron to leak out.
(4) When furnace leakage occurs, the safety of personnel should be ensured first. When considering equipment safety, the equipment mainly considers the protection of induction coils. Therefore, if furnace leakage occurs, the power supply should be turned off immediately and the cooling water should be kept unblocked;
