Crucible resistance furnace is developed for industrial and mining enterprises, research institutes and laboratories for metal, ceramic firing, when heated to dissolve the analysis and small steel heat treatment. Crucible resistance furnace cycle mode of operation trolley furnace, crucible resistance furnace furnace shell made of high quality steel plate welded cylinder, inside lining made of silicon carbide or high alumina refractories gather light. Firing from inside the lining alloy wire heating element made resistance furnace crucible furnace door hinge fixed on the electric panel, door open and flexible. Crucible resistance furnace temperature rating of a number of options within the 1000 ~ 1600 ℃. Use of electric furnace metallurgical furnace heating effect - SG electric stove. Electric equipment are usually sets of 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 (electrical instruments, 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 heat treatment furnace, 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; Product Quality good. 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 electric box furnace, since the 1950s, due to 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, trolley furnace, furnace, laboratory furnace provided by Longkou Longkou Furnace experiment. Longkou experiment Furnace (www.lk-dianlu.com) strong, credible, in Yantai, Shandong electric equipment industry has accumulated a large number of loyal customers.
