Arc furnace for sale: 1 ton to 120 tons are available, as well as super power.
In industrially developed countries, some electric arc furnace steels are general steel grades, and electric arc furnace steelmaking has become an important conventional production technology,
not just a special production technology for producing special steel and alloy steel.
The rapid development of this technology is suitable for the following main conditions:
(1) The smelting cycle is shortened to 60~100min.
(2) Sufficient electric energy, stable electricity price, and electricity consumption per ton of steel is not more than 375KW·h.
(3) Electric furnaces tend to be large-scale and ultra-high-power, and cooperate with out-of-furnace refining, the smelting process is strengthened, and the productivity is greatly improved.
(4) The temperature and composition of molten steel are easy to control, and the variety adaptability is wide.
Arc furnace for sale is an electric furnace that smelts ores and metals using the high temperature generated by an electrode arc.
When the gas discharge forms an arc, the energy is very concentrated, and the temperature of the arc zone is above 3000 °C.
For smelting metal, the electric arc furnace is more flexible than other steelmaking furnaces, and can effectively remove impurities such as sulfur and phosphorus, and the furnace temperature is easy to control.
It’s suitable for the melting of high-quality alloy steel.
The arc furnace for sale has also become a big market demand.
Advantage
Advantages of electric arc furnace steelmaking:
Electric furnace steelmaking is the main method for producing special steel in countries all over the world.
It has the following advantages:
①The equipment investment of electric furnace steelmaking is low and the infrastructure construction speed is fast;
②The heat energy of steelmaking comes from the arc, the temperature can be as high as 4000~6000°C, and it acts directly on the charge, and the thermal efficiency is relatively high, generally above 65%.
In addition, high alloy steels such as refractory elements W and Mo are contained in the smelting;
③Electric furnace steelmaking can remove the inclusions and harmful gases contained in the steel, as well as desulfurization, deoxidation, coalescence, etc., so as to smelt high-quality special steel;
④Electric furnace steelmaking can use hot charging or cold charging, which is not limited by the charge;
⑤It has strong adaptability and can be produced continuously or intermittently.
Arc Furnace For Sale
In the past 20 years, oxygen technology for electric arc furnace steelmaking has made remarkable progress.
The utilization of oxygen has jumped from the initial decarburization reaction to become the second heat source of the electric arc furnace, partially replacing the relatively expensive power source.
The oxygen supply of modern electric arc furnace steelmaking is 20~40m3/t, or even higher.
The chemical energy it provides to the molten pool accounts for 30% to 40% of the total input energy.
Advanced electric arc furnaces widely use technologies such as enhanced oxygen supply, foamed slag smelting, and scrap steel preheating, so the smelting time of electric arc furnaces is greatly shortened.
The consumption is not more than 375kW·h, and the consumption of electrodes per ton of steel is not more than 1.5kg.
Modern steelmaking processes are mainly converter processes and electric furnace processes.
No matter what type of smelting furnace, we can provide corresponding plans and design drawings according to the specific requirements of customers, and arc furnace for sale.
