Any machine or equipment has its service life. Of course, as the darling of the forging industry, the induction melting furnace also has its service life. But don’t panic. As the saying goes, “Three points are used, seven points are raised.” As long as you have good habits and proper use methods in the process, you can extend the life of your induction melting furnace for several years. Today I will teach you How to use the induction melting furnace to extend its life.

A, the molten iron should be emptied when the furnace is stopped

During the use of the induction melting furnace, occasional failures such as failures and power outages may cause the induction melting furnace to stop for a long time. Then during this period of furnace shutdown, the molten iron remaining in the furnace must be emptied, so as to avoid damage to the furnace lining due to the cracking of the furnace lining during a long period of time when the molten iron is condensed; Condensation began. At this time, if the condition of the furnace lining cannot be determined, the furnace should be cut off and then disconnected to prevent greater damage and reduce the service life of the induction melting furnace.

B, the furnace should be cooled down evenly

Everyone knows that heating and cooling will destroy the structure of metal. Therefore, when the furnace needs to be stopped for cooling after high-temperature operation of the induction melting furnace, sudden cooling must be avoided, and an empty furnace cooling should be performed. And in order to avoid that the temperature difference between the upper, middle and lower parts is too large during the cooling process of the furnace lining and cracks are generated, the furnace cover needs to be covered, so that the furnace lining is cooled uniformly up and down, thereby extending the service life.

C. Preheating of the cold furnace

The car needs to be warmed up in advance to extend the life of the engine, as is the induction melting furnace. Induction melting furnaces will inevitably have vertical cracks when the furnace is cold. At this time, if the cold furnace is started, it must be preheated at a low temperature, and then the temperature is gradually increased for the melting operation. This can make the previous cold furnace appear The cracks are closed first, which can prevent the molten iron from penetrating into the cracks and causing the cracks to continuously expand.

D. Please check carefully for daily use

Inspection is the work to be performed when almost all equipment and machines are used. Good inspection habits can avoid many incidents and indirectly extend the life of equipment. The inspection of the induction melting furnace should be done "once every three days and the wall every day." This means that the furnace low should be measured every three days, and the condition of the furnace wall should be observed every day.

E. Maintenance is also important

Except of course. The maintenance of induction melting furnaces is also very important to extend their life. For example, it is necessary to regularly clean the coil and clean up the debris on the coil, which can effectively prevent the breakdown of the coil. Therefore, the occurrence of furnace dismantling due to equipment failure can be reduced, and the service life of the crucible can be significantly improved.

F. The new furnace process should be done well

The reason that the new iron pan needs to be opened is that the process of using the new furnace can effectively adapt the induction melting furnace to the working environment. Here are some points to note during the use of the new furnace

1. In the first furnace of the new furnace, only 50% of the water from the first furnace should be melted. This can effectively avoid defects such as cracking of the furnace lining after the water is quenched after all the water is discharged.

2. In the process of using the new furnace, whenever it is unloaded, it should be handled as lightly as possible to avoid the impact of heavy objects on the bottom or the wall of the furnace, which will cause the lining to peel off.

3. When the new furnace is first used, try to perform long-time melting at one time. This can effectively shorten the period of the melting and the furnace body temperature is suddenly cold and hot, which will cause cracks. The editor here recommends continuous melting for at least 6 days, which can effectively improve the life of the induction melting furnace.

G, excessive temperature should be avoided

During the use of induction melting furnace, try to avoid excessively high temperature melting operations. Because the high temperature will cause the crucible to react with the molten iron and the furnace lining. Causes certain damage to the stove. Generally, it should be controlled between 1490 ° C and 1510 ° C. At the same time, after the water is discharged, the power is turned off to keep the induction melting furnace at a relatively low temperature. When the water is ready to be discharged, the temperature is increased according to the temperature of the previous pack of water. This can reduce excessive erosion of the furnace lining by the high temperature molten iron. Can reduce power consumption, can save energy, and at the same time increase the life of the furnace.

H. Smelting workers should be careful

In addition to some tips that can prolong the service life, during the daily use of the induction melting furnace, good operating habits can also effectively increase the service life of the induction melting furnace. For example: due to the rapid heating process of the induction melting furnace, the smelter should pay attention to the phenomenon of "bridge bridging" of the furnace material and cause the furnace lining to have a local high temperature, even exceeding the refractory temperature of the furnace lining; When the temperature is too high, the lining may be melted and damaged; therefore, the smelter must be hard-working during the melting process, and the front-end worker must adjust the temperature of the molten iron according to the color of the molten iron at any time to adjust accordingly to ensure the safety of the lining.

The above are some tips to extend the life of the induction melting furnace Only if any equipment is well maintained, can it better serve people and bring their greater value into play.
