Kaedah rawatan kemalangan kebocoran besi cair dalam relau peleburan logam
Kaedah rawatan kemalangan kebocoran besi cair dalam relau peleburan logam
1. Kemalangan kebocoran besi cecair berkemungkinan menyebabkan kerosakan pada relau peleburan logam malah membahayakan tubuh manusia. Oleh itu, adalah perlu untuk melakukan penyelenggaraan dan penyelenggaraan relau peleburan logam sebanyak mungkin untuk mengelakkan kemalangan kebocoran besi cecair.
2. When the alarm bell of the alarm device rings, immediately cut off the power supply and inspect the furnace body to check whether the molten iron leaks out. If there is any leakage, dump the furnace immediately and finish pouring the molten iron. (*Note: Usually, there must be an emergency spare molten iron ladle whose capacity should be greater than the maximum molten iron capacity of the metal smelting furnace or keep the molten iron emergency pit in front of the furnace dry and free of other flammable and explosive materials.) If there is no leakage, follow the leaking furnace alarm inspection procedure Carry out inspection and processing. If it is confirmed that the molten iron leaks from the furnace lining and touches the electrode to cause an alarm, the molten iron must be poured out, the furnace lining should be repaired, or the furnace should be rebuilt. If a large amount of molten iron flows out and damages the induction coil to cause running water, the molten iron should be poured out in time, the water should be stopped, and the water should not be in contact with the molten iron to prevent explosion.
3. The molten iron is caused by the damage of the furnace lining. The thinner the thickness of the furnace lining, the higher the electrical efficiency and the faster the melting rate. However, when the thickness of the lining is worn less than 65mm, the entire thickness of the 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. This crack can rupture the entire interior of the furnace lining and easily cause the molten iron to leak out.
4. Pembinaan relau yang tidak munasabah, penaik, kaedah pensinteran, atau pemilihan bahan pelapik relau yang tidak betul akan menyebabkan kebocoran relau dalam beberapa relau pertama lebur. Pada masa ini, peranti penggera relau yang bocor tidak boleh penggera. Beri perhatian khusus kepada fakta bahawa jika peranti penggera relau bocor tidak penggera, semak penggunaan relau dengan kerap mengikut pengalaman penggunaan, kerana elektrod relau bocor tidak dipasang dengan betul atau sentuhan tidak baik. Relau peleburan logam tidak boleh penggera dengan tepat, yang menjejaskan pemeriksaan relau peleburan logam untuk menyelesaikan masalah dalam masa untuk memastikan keselamatan.
