The principle of intermediate frequency furnace steelmaking technology encyclopedia why casting steel to choose medium frequency furnace?
Using the electromagnetic induction principle to make heating furnace charge ontology, thus fast heating and melting period is short, high thermal efficiency;
Heat energy is clean, not a lot of flame and gas emission in the process of heating and low pollution, reduce the investment of environmental protection equipment;
Due to electronic technology.
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.
What is the difference between the electric arc furnace and intermediate frequency furnace principle of intermediate frequency furnace steelmaking answer: 1, the electric arc furnace, big volume are generally not more than 3 tons, have a certain scale enterprises 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
? Answer: that the future of the intermediate frequency furnace steelmaking with development, the government is now advocating environmental protection, coal, diesel oil, liquefied petroleum gas not only doesn't conform to the requirements of environmental protection, and the price and also not economic sense;
Saving energy and reducing consumption, reduce costs will become small and medium-sized enterprise is very pressing issue, and electricity induction heating is not only stable and reliable in operation, high efficiency and energy saving and safety.
Want to ask, steel mills in medium frequency furnace, no matter what type, all answer: comrade, full name is called the intermediate frequency induction refining furnace, intermediate frequency furnace is by the current into a magnetic field, with a magnetic field can be converted into electrical current, to produce the principle of heat to melt scrap steel.
Electrode is used for?
That are used to produce the electric arc, so the intermediate frequency furnace is without electrode.
So no matter what type of intermediate frequency furnace are not used electrode.
How intermediate frequency furnace steelmaking desulfurization answer: no points?
That will simplify the answer change slag, build new slag.
Have divided the detail then and say, I don't know right oh, but doing so is bound to desulfurization.
First, must have a lot of people know, high temperature desulfurization for medium frequency, the temperature is above 1600.
Second, the desulfurization is to have a reducing atmosphere, so the slag adding aluminum powder or.
Why countries advocate with medium frequency induction heating furnace steelmaking answer: one is the chemical composition adjustment is not easy.
ZGMn13Cr2MoVTi afraid of a steel grade, such as smelting in medium frequency furnace smelting, is more difficult.
When all molten steel, sampling to do during the test, high temperature molten steel to the harm of lining is larger, that is to say, the test time is very short, and test after adjusting chemical composition is not easy.
The second is the limited capacity of intermediate frequency furnace.
The difference between induction medium frequency furnace and electric furnace, which make steel?
The advantages and disadvantages?
The principle of intermediate frequency furnace steelmaking answer: actually not steelmaking with medium frequency furnace, is to melt the steel, the impurities in the steel can't take out, can only rely on slag.
This is a disadvantage.
Advantage is that it turns out that some elements of the steel basic don't loss, can reduce the amount of valuable elements to add, reduce the cost.
Arc furnace can be burnt up all the impurities in the steel scrap and precious metals, and then add the various elements as required.
Can intermediate frequency electric furnace steelmaking?
Need the original material.
A: intermediate frequency electric furnace steelmaking, not right, it's just done 'melting' real steel is' smelting, refining can't use the intermediate frequency furnace.
The prospects of intermediate frequency furnace steelmaking?
The principle of intermediate frequency furnace steelmaking answer: it depends on what steel smelting, you now transformer application is not good, nor too encouraging countries to this field, because it is high energy consumption.
Special steel this country is not too limit, but the market is saturated, the competition is fierce.
Money takes up a lot of, it is difficult to see earnings, money takes up on goods, there is customer YaKuan above, do not charge money so.
The principle of intermediate frequency furnace steelmaking technology data of eia in the intermediate frequency furnace steelmaking why must have a spare stove a: intermediate frequency furnace steelmaking power consumption related to many factors, such as the stand or fall of the filial piety of scrap steel and medium frequency furnace furnace working technology and frequently lazy and so on.
Generally speaking, the power consumption between 550 ~ 750 degrees, large-tonnage stove and lower power consumption, small tonnage.
Intermediate frequency furnace steelmaking to drop the principle of intermediate frequency furnace steelmaking answer: sulfur acid furnace, is can't use lime, from raw materials on hand, only can use limestone saltiness furnace.
There are a lot of businesses today that are very much in demand and one of them is a electric melting furnace aluminum.
With comprehensive knowledge on aluminum smelting furnace,why not visit the highly recommended site Induction furnace, Induction melting furnace manufacturer, induction furnace manufacturers to get a full appreciation of the best ?
To offer abundant options of product is an important factor to a company, such as continous casting machinecoreless type induction furnace to afford high-quality products for customers.
Equipping induction electric furnace with innovative technology and updated processes will simplify daily compliance duties so that they can focus on attracting, retaining, and developing the most engaged workforce possible.
A wholesaler should have many cast iron melting furnace based products that could help you if you have a induction heating furnace with automatic feeder problem. It is better to treat the problem early rather than have to deal with it later. Foshan Hengyang Furnace Manufacturing Co.,Ltd. is your best choice.
