1T intermediate frequency melting furnace equipment acceptance procedure
The acceptance of the 1T intermediate frequency melting furnace is carried out twice, the first time is the pre-acceptance, and is carried out at the supplier's factory; the second is the final acceptance, which is carried out at the place where the equipment is used. 1, 1T medium frequency melting furnace factory acceptance (pre-acceptance) 1) Simulation test. A. The simulation test is completed by the technicians of the supplier and the supplier. B, making analog sensors C. The equipment reaches the rated power, and the frequency meets the scope specified by the equipment design specifications. D. The equipment is operated continuously for 1 hour at 90%-110% of the rated power of the test. E. The equipment is frequently started for 1 hour at 90%-110% of the rated power of the test (10 seconds of operation for 10 seconds). F. Provide a simulated test report. 2) Dynamic test of 1T medium frequency melting furnace A. The dynamic test is completed by the technicians of the supplier and the supplier. B. The tester provides two kinds of test steel pipes, each of which is not less than 2m in length. C. The supplier provides working sensors (3 specifications). D. The supplier simulates the arrangement of the field equipment, completes the static diathermy process test by using the test steel pipe, and calculates whether the heating power source meets the process requirements by detecting the heating temperature, heating time and heating power of the steel pipe. E. Provide a dynamic test report. 3) 1T intermediate frequency melting furnace factory acceptance record A. The continuous operation record of the equipment under rated working conditions. B. The frequent start record of the equipment under rated conditions. C. Dynamically simulate the process parameter record of the diathermy test. D, cooling water system operation record. E. Equipment appearance quality record and modification record. 2. Equipment site acceptance (final acceptance) 1) Acceptance criteria A. The equipment has the ability to meet the requirements of the user's process (Part 2) B. The intermediate frequency induction heating power supply reaches the third part of the main technical indicators. 2) 1T medium frequency melting furnace acceptance method The acceptance of the user is the final acceptance. 3) Guaranteed value A, reach the nominal power of the device B. Meet the requirements of continuous work system C, meet frequent start / stop requirements
