Use of electric furnace metallurgical furnace heating effect - SG electric stove. Electric equipment are usually sets of experimental furnace electrical equipment including electric furnace (EAF transformer, rectifier, inverter, etc.), opening and closing, a subsidiary auxiliary appliances (chokes, capacitors and other compensation), vacuum equipment, measurement and control instrumentation (electrician instrumentation, thermal instrumentation, etc.), automatic control system, furnace machinery and equipment (access to materials machinery, furnace tilting devices, etc.). Large electric power equipment and measurement and control instrumentation generally concentrated in the electric power supply room. Compared with fuel stove. Furnace Advantages are: easy to control the furnace atmosphere, or even evacuated; material fast heating, the heating temperature is high, the temperature is easy to control; the production process easier to achieve mechanization and automation; good industrial hygiene; high thermal efficiency; good product quality, etc. . Metallurgical industrial furnace is mainly used for smelting iron and steel, ferro-alloys, non-ferrous metals, the heating and heat treatment. Appeared in the late 19th century industrial-scale furnace, since the 1950s 1600 degrees laboratory furnace, because of the high level of metallurgical products and electricity demand growth with the development of the electric power industry and the decline in the metallurgical furnace scale furnace equipment increased year by year. Furnace can be divided into resistance furnace, induction furnace (EAF SG), electric arc furnace, plasma furnace, electron beam furnace, laboratory furnace use and classification applied to today's small batch of experiments and with universities, industrial and mining enterprises. Many different types of laboratory furnace, but can be roughly classified in the following aspects: 1 from the hearth shape can be divided into: Box resistance furnace and tube resistance furnace; two from the procedure can be divided into: manual programming resistance furnace and intelligence resistance furnace; three necessary conditions from the experimental atmosphere can be divided into: oxidizing atmosphere and vacuum resistance furnace resistance furnace atmosphere. 4. From the maximum temperature can be divided into: low-temperature resistance furnace (600 ℃ or less) high temperature laboratory furnace, furnace temperature resistance (600 ℃ -1000 ℃), high temperature resistance furnace (1000 ℃ -1700 ℃), ultra-high temperature resistance furnace (1800 ℃ -2600 ℃). Tube type laboratory furnace, laboratory furnace, laboratory furnace provided by Longkou Longkou Furnace experiment.
