Induction furnace operation on several matters needing attention

Induction furnace operation on several matters needing attention

1) induction furnace blow-in must first inspection before pushing, discharging device, water, air pressure is normal, limit switch, automatic and manual switch position is in the required position, check whether the workbench billet conform to the requirements of the forgings. Cooling water is the lifeline of induction furnace, the cooling water must always focus on, export water temperature shall not exceed 60 ℃.
2) start after the induction furnace, heating parameters, after waiting for heating parameters stable heating can be normal production.
3) cold furnace condition under-burnt clinker for the first time at work, should not be used immediately rated power, should use the normal power from 60% to 75% for low temperature heating, can avoid lining cracks, lining uniform temperature reaches 90 ℃, can enhance power to normal process power, formally began forging operations.
4) to correctly put billet in the process of loading, all burrs or deformation of big billet after processing must take place before furnace charging, and want to pay attention to loading method, place "horseshoe" upward, so as to avoid stuck very bad lining.
5) before the furnace and the work should not be on stage at the same time there are two parts of billet, residual billet heated furnaceman must under the shift into the container, indicating the billet size and status, the red material should finish forging furnace. Induction furnace is a kind of electric heating furnace, there are a lot of advantages: warming faster, less oxidation and decarburization, good working conditions, easy to realize mechanization and automation. But the size of billet shape change adaptability is strong enough. When the size of the blank shape changes within the specified requirements, such as shortening the length or added new billet size, etc., it can't just casually discharging pushing, must be conducted in accordance with the requirements of the design of the sensor discharging pushing related calculation, so as to ensure the quality of billet heating, otherwise will produce heat.
