An industrial furnace is an industrial heating device that heats materials and makes them undergo physical and chemical changes.https://www.vacfurnace.com/technology-frontiers/heat-treatment-of-dz4-alloy-in-high-pressure-gas-quenching-vacuum-furnace/In 1794, a straight-tube cupola for melting cast iron appeared in the world. In 1864, the Frenchman Martin used the principle of the regenerative furnace of the British Siemens to build the first steel-making open-hearth furnace heated by gas fuel. He used the regenerator to preheat the air and gas at high temperature, thus ensuring the temperature above 160OC required for steelmaking. Around 1900, the power supply was gradually sufficient, and various resistance furnaces, electric arc furnaces and core induction furnaces were used.

Then came the electron beam furnace, which used electron beams to impinge solid fuels to intensify the surface heating and melting of high melting point materials.
