Abstract
The utility model relates to a triple-frequency induction electric arc furnace which has a structure that two holes are arranged on a refractory sealing furnace cover of a triple-frequency induction furnace; two graphite electrode bars respectively pass through the two holes; an electrode bar arcing space adjusting mechanism is arranged on the triple-frequency induction furnace; the triple-frequency induction electric arc furnace adopts power sources which are special power sources for direct current controlled triple-frequency transformers. The utility model has advantages of temperature rising quickness, high temperature, short smelting period, electricity saving, long service life, easy operation and capacity of directly rising up temperature of slags, and can be used for melting various kinds of high-quality steel. No existing electric arc furnace or existing induction furnace can be comparable with the utility model.
Description
The utility model relates to induction heater or arc discharge heating furnace technical field.
Smelting furnace has electric arc furnaces and power frequency induction furnace at present, and electric arc furnaces is fit to steel-making, but complex structure, smelting time is long, and general 0.5T stove needs 4 hours; Power frequency induction furnace power consumption is big, and the slag temperature is low, and smelting time is shorter than electric arc furnaces, and general 0.5T stove needs 2.5 hours, but the steel-making weak effect can not be used to refine many variety steels, high-quality steel, and lining durability is short, and use is closed by general 2 All-China Federation of Taiwan Compatriots, the cost height.
The purpose of this utility model provides a kind of frequency tripling induction arc funace, and it not only has quick heating, smelting time is short, and the temperature height, can be used for smelting many kinds high-quality steel, and power savings is very remarkable simultaneously.
The utility model is achieved in that a kind of frequency tripling induction arc funace, it is characterized in that having a frequency tripling electric induction furnace, cover at the refractory material Sealing furnace of this electric furnace and to be provided with two holes, two starting the arc graphite electrode rods pass two holes, and being provided with electrode bar starting the arc spacing guiding mechanism, the power supply of the power supply of two electrode bars and frequency tripling electric induction furnace is DC control frequency tripling transformer power source special.
Above-mentioned electrode bar spacing guiding mechanism can be bolt adjustable type or leading screw adjustable type etc., manually or electrodynamic type etc.
In order to reduce volume, it is coaxial staggered relatively or oblique staggered relatively etc. that handled easily, two above-mentioned root graphite electrode rods are preferably level, and the centre has starting the arc spacing, is easy to adjust.
For life-saving, the refractory material of above-mentioned sealing bell can use the aluminum-spinel agglomerated material, about 2000 ℃, forms with the special sintering furnace sintering of inventor's patent applied for, can establish the crucible cover sheet below bell.
The most handy aluminum-spinel sintered crucible of above-mentioned crucible, special sintering furnace is made.
Because the utility model is to have increased frequency tripling graphite electrode rod electric arc structure on the basis of the inventor's patent, so the advantage that shows when melting is very outstanding, thereby it is long to have solved the original arc melting time effectively, power frequency induction furnace power consumption is big ... difficult problem that can not many kinds of melting high-quality steel, the concrete advantage of the utility model is: 1, quick heating, smelting time is short, and is also shorter than power frequency induction furnace; 2, temperature height can directly make slag heat up, and the melting quality is good, can refine the high-quality steel, many variety steels; 3, power savings is remarkable, and for example the molten steel ton power consumption of electric arc furnaces is 600-700 kilowatt-hour, and the utility model can reach 550-600 kilowatt-hour; 4, lining durability is long.The characteristics that this also is to use the induction furnace of inventor's frequency tripling induction furnace power source special patent to have.The stove cost reduces, and economic and social benefit is remarkable.
Be described further below in conjunction with embodiment and accompanying drawing, but not as to qualification of the present utility model.
Fig. 1 is its structural representation.
Among Fig. 1; 1 is the frequency tripling electric induction furnace, and 2 are sealing bell, the 4th, loose sealed material; 5 is the aluminum-spinel agglomerate; 6 is the hole on the bell, and coaxial graphite electrode rod passes the safe starting the arc in arc chamber in 3,7 holes; 8 are starting the arc electrode bar bolt governor motion; 9 is crucible high temperature protection cover plate, is preferably made by the aluminum-spinel sintering, or uses other exotic materials.10 is slag, and 11 is inductor, and 12 is the electric arc furnaces fixing bracket body.Electric arc rod and induction furnace power supply all use 60 or 300KVA frequency tripling electric induction furnace power source special (patent No. is ZL94216295.1), can produce 3000 ℃ electric arc, make slag be warmed up to 2000-2200 ℃, so improved the steel-making quality.Furnace lining also can be brought up to the 600-800 heat by 200 original heats.The refining one heat steel can be no more than 2 hours, and power savings is very remarkable.
