dvantages steelmaking furnace

High power electric arc steel melting furnace has outstanding advantages, but must have the following conditions in order to give full play to the role: ① strong supply network. Short circuit capacity should be more than 80 times the maximum capacity of the furnace transformer. Or install a huge capacitor compensation device (the high cost of doing so) to reduce voltage fluctuations on the network, so affect the normal operation of other electrical equipment. ② high power electrodes. UHP unit time input energy is much higher than ordinary power electric arc furnace, which is the same cross-section of the general power of the electrode is not competent. Increase the electrode sections will make it support, drive and even bulky structure of the entire furnace, but also cause difficulties for the control system. High power electrode is a material needle pitch, the electrode having a crystal structure orientation. Its electrical conductivity, thermal conductivity, oxidation resistance, strength and other properties are better than ordinary power electrode of the same section. ③ efficient production management system. High power electric furnace for 19 survey results indicate that about 20% to the effects of ultra-high-power, 60% played only 60 to 70 percent of capacity, while 20% are not functioning. Among them, the production organization and management is extremely important, not simply that, with a large capacity electric arc furnace transformer will be able to achieve the desired objectives.
As a result of high power electric arc steel melting furnace and various refining method, an arc steel melting furnace melting apparatus serving as a simple trend; steel and configuration adapted to the production and refining equipment, the use of the furnace transformer in order to fully ability to improve steel production.

Aluminum Melt furnace Introduction

Aluminum Melt furnace is based on the aluminum smelting process and the development of a new energy-efficient aluminum melting furnace, mainly used for melting and holding of aluminum ingots, which can satisfy the aluminum smelting process. Aluminum Melt furnace by melting furnaces, crucibles, heating elements, lid lifting mechanism, automatic temperature control system and other electrical components. Housing made of steel and steel plate welded into a cylindrical shape. The front end of the lower portion of the furnace body has a hole for the formation of the crucible due to corrosion, oxidation of the crack drips case, can melt in the crucible furnace body through which the flow to the furnace will not be damaged so that the studio.

steel melting furnace classification

There BOF steel melting furnace, open-hearth, electric furnace steelmaking other vacuum induction furnace, vacuum arc, electron bombardment furnace.
BOF is molten iron, scrap, ferroalloys as the main raw material, without the aid of external energy, relying on their physical heat of molten iron and molten iron to produce a chemical reaction between the components of the heat in the converter steelmaking process is completed. BOF divided by acidic and basic refractories, by gas blown into the furnace site has top blowing, bottom blowing and side-blown; according to the type of gas for the sub-air converter and oxygen converter. Basic oxygen top blowing and the top and bottom blowing converter due to its production speed, yield, high single furnace yield, low cost, low investment, is currently the most widely used steel-making equipment. Converter is mainly used for the production of carbon steel, alloy steel and copper and nickel smelting.
Open-hearth open-hearth steelmaking operation process raw materials as follows: ① steel materials such as pig iron or molten iron, scrap; ② oxidants such as iron ore, industrial oxygen, artificial bonanza; ③ slagging agents such as lime (or limestone), fluorite, iron bauxite; ④ deoxidizer and alloy additives.
The main advantage of electric arc furnace steelmaking heat, electric arc zone in temperatures up to 4000 ℃. Smelting process is generally divided into the melting period, the oxidation and reduction of the period, not only can cause oxidation in the furnace atmosphere, but also result in a reducing atmosphere, so dephosphorizing high desulfurization efficiency.
