Maintenance of frequency furnace
The maintenance of medium frequency induction furnace is very important in production. It can find all kinds of hidden dangers in time, avoid major accidents, prolong service life, ensure production safety, improve casting quality and reduce cost. Regularly record relevant electrical parameters, cooling water temperature and temperature of key parts of furnace body (such as furnace bottom, furnace side, induction shell copper bar, etc.) to monitor the operation of electric furnace at any time. Start the diesel generator regularly to ensure its reliable operation.
1. Regular maintenance, lubrication and fastening of electric furnace shall be carried out according to the specified time (such as dedusting the sensing ring, copper bar, electric control cabinet, etc. with anhydrous compressed air, and lubricating and fastening bolts on the lubricating parts).
2. Observe the water pressure gauge, water temperature gauge and check the aging degree of rubber hose every day; Regularly check the flow of each cooling water branch to ensure that the pipeline is not blocked and the pipe joints are not leaking, especially the cooling water connector in the solid power supply cabinet. If water leakage is found, tighten the pipe joint clamp or replace the clamp; regularly check the water in the spray tank and expansion tank of the water tower, and store water in the power cabinet and water tank, and supplement them in time; and check frequently For the condition of standby pump, the standby pump should be used every 3-5 days to ensure the absolute reliability of the standby pump.
