Intermediate frequency furnace heating steel set an intermediate frequency furnace principle answer: medium frequency induction furnace works: PS series power supply adopt ac - Dc - Ac frequency conversion way, by a ( Or two) Three-phase bridge rectifier three-phase alternating current into direct current, and then by a single-phase bridge inverter dc into intermediate frequency alternating current (ac), and intermediate frequency ac induction coil, when passing a medium frequency induction coil produces alternating alternating current (ac). Consult, steel wire after into the intermediate frequency furnace heating, why into the intermediate frequency furnace heating steel shall be a: intermediate frequency furnace heating is recrystallization annealing, to enter the cooling water tank for cooling is to prevent blue brittleness and deformation, such as temperature is too high, or steel wire internal injuries, there will be a wire broken wires, away from the water after the failed to timely did not add rust inhibitor in cooling water, dry will rust. What is the intermediate frequency furnace? What are doing? Intermediate frequency furnace heating steel set a: medium frequency furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency ( More than 300 hz - 1000 hz) Induction coil, power supply units, deserve to go up and compensation capacitor, applied the principle of electromagnetic induction heating equipment, widely used in non-ferrous metal melting, heating. Such as molten pig iron practice, ordinary steel, stainless steel, tool steel, copper, aluminum, gold, silver and alloy, etc. ; Diathermy forging purposes. How steel furnace heating a: steel heat source mainly include physical and chemical physics hot mainly electricity, stoves with electric arc furnace LF ladle refining furnace and so on chemical intermediate frequency furnace mainly carbon oxygen exothermic reaction, hot stove have AOD furnace VOD furnace of converter and so on. Intermediate frequency electric furnace steel shell, the working principle of the citric acid made answer: intermediate frequency furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency ( More than 300 hz - 1000 hz) Power supply device, the three-phase alternating current (ac) power frequency, after rectification into direct current, then laid adjustable intermediate frequency electric current, direct current supply by capacitance and induction coil in through the intermediate frequency alternating current, generate high density magnetic field lines in the induction coil, induction coil, and cut in. Steel is heated to 900 degrees Celsius is what state of intermediate frequency furnace heating steel set answer: it depends on the steel grade and decide if it is high temperature resistant alloy steel that is slightly red, few strength hardness drop if is the relatively common carbon steel and low carbon becomes very soft can free forging. Intermediate frequency furnace steelmaking process, and the relevant matters needing attention! 2: feeding by furnace of work completed, at the time of loading, dropping material, melt faster, pay attention to have a seal can't add, of cold water as much as possible in the oven baked first, and pay attention. Steel pipe end annealing of intermediate frequency furnace is how to work? A: heat the steel to a certain temperature and heat preservation for a period of time, and then make it slowly cooling, called annealing. Steel pipe annealing is a heat the steel to the phase change or part of the phase transition temperature, slow cooling after heat preservation heat treatment method. : the purpose of annealing is to eliminate defects, improve the organization make composition uniformity and fine grains, increase mechanical properties of the steel. Intermediate frequency furnace also calculate the microwave a? Answer: heating principle of intermediate frequency furnace and microwave oven are completely different. Intermediate frequency furnace is generated by electromagnetic induction eddy current to heat metal, mainly used in the heating of the steel. And microwave is using molecular vibrations caused by heating, mainly applied in the field of non-metallic, especially the food. 1 acid lining material: carbon steel smelting. Quartz sand ( 20/40) 40%, quartz sand, 50/100) 5 ~ 2% ( Plus) 2%, water ( Plus) 。 Quartz sand should be magnetic separation, remove the ferromagnetic material. Alkaline lining: for alloy steel smelting. Magnesia ( A 4 x 4 mm sieve) 96%, refractory clay, No. 100. Intermediate frequency furnace heating steel technical data set what is the difference between electric arc furnace and intermediate frequency furnace answer: 1, the electric arc furnace, big volume are generally not more than 3 tons, have a certain scale of the enterprise to use the electric arc furnace, smelting steel is more pure. Intermediate frequency furnace: relative electric arc furnace steelmaking cost lower, suitable for small and medium enterprises, refining the steel material, high carbon steel coming out is not so pure. 2, electric arc furnace with electric power frequency; Intermediate frequency electric furnace used. What kind of work efficiency high and moderate frequency medium frequency electric furnace heating furnace of steel set a: intermediate frequency electric furnace is a kind of will power frequency 50 hz alternating current into intermediate frequency ( More than 300 hz - 10000 hz) Power supply device is controlled by frequency conversion device, furnace, furnace before such a few parts. Chinese intermediate frequency electric furnace equipment principle of three-phase power frequency alternating current into direct current advantage after rectifying element layout reasonable coordination, easy maintenance features low temperature around the stove.
