Safe operation of complete set of medium frequency quenching and tempering production line
1、 Precautions before opening
The electric equipment, water cooling system, inductor copper pipe, etc. must be inspected before the start of the medium frequency electric furnace. The furnace can be started only when these equipment are in good condition to ensure the safety of heat treatment. Otherwise, it is forbidden to start the furnace. The personnel specially responsible for power transmission and start-up shall be determined, and the personnel in charge shall not leave the post without permission. During the work, the external conditions of the inductor and crucible must be checked Condition supervision shall be carried out to prevent someone from touching the inductor and cable after power transmission, affecting the normal operation of medium frequency electric furnace or causing safety accidents.
2、 Precautions after opening
After the medium frequency electric furnace is opened, when charging, the furnace charge shall be checked to avoid mixing with inflammable, explosive and other harmful substances. In order to prevent the phenomenon of capping, it is strictly prohibited to directly add cold and wet materials into the molten steel, and do not add bulky materials after the molten liquid is filled to the upper part; in order to avoid explosion accidents, it is necessary to ensure that the pouring site and the pit in front of the furnace are free of water and obstacles; while in the process of pouring, it is necessary to cooperate with two people, and the remaining molten steel can only be poured in the designated place, not in the designated place Fall everywhere.
3、 Precautions for maintenance
During the maintenance of intermediate frequency electric furnace, the room of intermediate frequency generator shall be kept clean, and it is strictly prohibited to stack inflammable and explosive materials. The furnace with excessive melting loss shall be repaired in time. During furnace repair, iron chips and iron oxide shall not be mixed to ensure the compactness of the crucible.
