What is the appropriate monthly salary for intermediate frequency furnace maintenance workers?

Nothing is absolute. It is said that it costs more than 9,000 yuan in January, 1000 in January and 45,000 yuan in January, mostly around 3,000-4,500 yuan. The key depends on the number of furnaces to be maintained and the operation mode of the electric furnace, whether it is continuous for 24 hours, at least 4500 yuan for two furnaces and 6000 yuan for more than four furnaces.
