Medium Frequency Furnace Leakage Furnace, Cause and Prevention

Medium Frequency Furnace


Medium Frequency Furnace Leakage Furnace, Cause and Prevention 



When a safety accident occurs, it should be reported to the leader or accident emergency team immediately. The medium frequency furnace body is leaking in a common accident. If no accident occurs, the coil copper tube will be broken, and the molten iron will contact with the coolant to cause an explosion. Therefore, the cause of the accident may be caused. Precautionary measures and plans for emergency measures should be given after the accident.


Causes of Leakage and Furnace Accidents


1. The cooling time of the molten iron is too long and the cover is closed, and it is thermally expanded again. The extrusion lining causes cracks in the lining. During the melting process, the molten iron passes through the crack, causing the furnace to pass through, or ejecting from the knot, causing the furnace accident.

2. As the medium frequency furnace age increases, the volume of the lining becomes larger, the amount of molten iron in the furnace increases and the furnace lining is thinner. Partially unable to withstand the pressure of molten iron caused the furnace to be worn, the lining of the lining did not meet the requirements or partially brought in impurities and was not found, resulting in the smelting from the above defects. The lining is quenched to produce cracks that pass through the crack during the smelting process.

Precaution:


From the beginning of the medium frequency furnace construction, special personnel must be strictly managed to ensure that each furnace lining is consistent. No debris is allowed to fall into the lining during knotting. Before each feeding, it is necessary to observe whether there is crack in the lining, and the perforation may cause the phenomenon of wearing the induction furnace. If there is a problem, it must be treated. During the smelting process, due to equipment failure or other factors, it is impossible to open the furnace for a long time. The molten iron should be turned out of the furnace to prevent the cover. The clean water pump can't work. When the production water stops, the lower water pump valve is opened, and the lower water pump is used to supply water to the furnace body. However, the pump water pump valve should be adjusted to reduce the water in the furnace body, and then the large well is low. The water intake valve opens.

Troubleshooting of Medium Frequency Furnace

Troubleshooting of Medium Frequency Furnace This article introduces the faults and solutions of medium frequency furnace. 1. Fault phenomenon: large DC current, low DC voltage, and if the voltage, dull equipment sound, over-current protection. Analysis and treatment: the thyristor with one arm of the inverter bridge may be short-circuited or open-circuited, resulting in the operation of the three-arm inverter bridge. Use an oscilloscope to observe the voltage drop waveform of the thyristor on the four bridge arms of the inverter bridge. If the voltage drop waveform of the thyristor on one bridge arm is a line, the thyristor has been through; if it is a sine wave, the thyristor has not been through. Replace the through thyristor; find out the reason why the thyristor is not turned on. 2. Fault phenomenon: when the heavy load cold furnace is started, all electrical parameters and sounds are normal, but the power cannot be raised, and overcurrent protection. Analysis and

Advantages and Disadvantages of Electric Arc Furnace and Induction Furnace Steelmaking

Electric Arc Furnace VS Induction Furnace Steelmaking Comparison of advantages and disadvantages of electric arc furnace and induction  furnace steelmaking 1. The induction furnace heats up quickly and has high thermal efficiency. The heat is generated inside the charge (steel liquid), so the heating is fast. In the arc furnace, the heat of the arc after the material is cleared must be transferred to the molten steel through the slag, which is indirect heating. Thermal efficiency is poor. The furnace is in the shape of a basin, and a large part of the heat of the arc is lost through the furnace cover and the furnace wall. 2. The oxidative burning loss of elements in induction furnace steelmaking is less. Because there is no ultra-high temperature action of the arc in the induction furnace steelmaking, the burning rate of the elements in the steel is low. 3. In the induction furnace steelmaking, the composition and temperature of the molten steel are relatively uniform.
