Usage and Maintenance of High Temperature Electric Heating Radiant Tube
1. Usage
(1) Prohibit long-term over-temperature and over-load use;
(2) When the furnace temperature is at a high temperature of 400℃, no rapid cooling is allowed;
(3) Do not touch the radiant tube during loading and discharging;
(4) When the furnace is working, always pay attention to whether the traffic lights on the control panel are normal, and the traffic lights should be exchanged once after a period of time during heat preservation to avoid burning the radiant tube due to the failure of the control switch;
(5) Pay attention to the working conditions of the instrument at any time, and analyze and deal with it in time when the furnace temperature and the indicator indication are found to be abnormal;
(6) For furnaces with a capacity of more than 100KW, each heating zone should be equipped with an ammeter for inspection, and each phase of the three-chamber high-temperature electric furnace should be equipped with an ammeter.
2. Maintenance
(1) After three to four months of use, take out the radiant tube, pour out the dust in the radiant tube, and turn the radiant tube 180° over and use it;
(2) Pay attention to the positive and negative poles of the radiant tube, and exchange the positive and negative poles every three to four months;
(3) After pulling out the radiant tube, when disassembling the terminal, be careful not to hit or knock the lead rod;
(4) The bolts leading out the terminal clamp are prone to oxidation and loosening, and should be checked and tightened regularly.
