いくつかの形式があります pre-forging heating equipment?

1. Flame heating: using solid (coal, coke, etc.), liquid (heavy oil, diesel, etc.) or gas (gas, natural gas, etc.) as the main fuel, the heat energy generated by the combustion of the fuel heats the inner cavity of the furnace, and then from the inside The hot air flow radiation in the cavity heats the blank.

This kind of flame heating forging heating equipment burns in the furnace to generate high temperature furnace gas (flame), through furnace gas convection, furnace wall (furnace wall and furnace roof) radiation and furnace bottom heat conduction, etc., the metal billet is heated and heated . In low temperature (below 650℃) furnaces, metal heating mainly relies on convection heat transfer, and in medium temperature (650-1000℃) and high temperature (above 1000℃) furnaces, metal heating is mainly by radiation.

2. Electric heating type heating: Electric heating type is a heating method that converts electric energy into heat energy, and there are two categories: resistance furnace and induction heating furnace. The resistance furnace is also to heat the furnace to the design temperature and then conduct it to the billet, while the induction heating is to achieve the purpose of heating by the electromagnetic induction of the billet itself.

Resistance furnaces generally include box-type resistance furnaces, trolley-type resistance furnaces, pit-type resistance furnaces, salt bath resistance furnaces, carburizing furnaces, etc.; induction furnaces include intermediate frequency furnaces, intermediate frequency electric furnaces, intermediate frequency melting furnaces, melting furnaces, diathermy furnaces, etc. Furnace, intermediate frequency heating furnace, heating furnace, intermediate frequency billet heating furnace, intermediate frequency quenching and tempering heating furnace, steel pipe perforation heating furnace, steel plate heating furnace, etc.
