Description
Technical field
The utility model relates to the EAF Technology field.
Background technology
Electric arc furnaces (electric arc furnace) is to utilize the high melt ore of electrode arc generation and the electric furnace of metal.Energy was very concentrated when gas discharge formed electric arc, and arc district temperature is more than 3000 ℃.For smelting metal, electric arc furnaces is larger than other converter technological flexibilities, can effectively remove the impurity such as desulfuration, phosphorus, and furnace temperature is controlled easily, and occupation area of equipment is little, is suitable for the melting of superior alloy steel.Electric arc furnaces can be divided into the types such as three-phawse arc furnace, consumable electroarc furnace, single-phase arc funace and resistor electric arc stove by electrical arc.The body of heater of electrical arc furnace is comprised of bell, fire door, lander and shaft, and build by laying bricks or stones with basic refractory or acid refractory furnace bottom and furnace wall.
Refine at present lateritic nickel ore industry development, need electric arc furnaces to refine.And at present electric arc furnaces is used for producing common straightcarbon steel in a large number.Existing electric arc furnaces is used for refining lateritic nickel ore and has complex structure, is not easy to the problem of discharging.
The utility model content
The utility model provides a kind of rotary kiln electric arc furnaces of direct refinement lateritic nickel ore, and the utility model has solved existing electric arc furnaces and had complex structure for refining lateritic nickel ore, is not easy to the problem of discharging.
For addressing the above problem, the utility model adopts following technical scheme: a kind of rotary kiln electric arc furnaces of direct refinement lateritic nickel ore comprises preheating rotary kiln 1 and electric arc furnaces 6; The curved bottom of electric arc furnaces 6 is arranged at above the electric arc furnaces bearing 7; Electric arc furnaces 6 internal upper parts arrange electrode 4, and electric arc furnaces 6 left and right sides have respectively electric arc furnaces charge door 3 and electric arc furnaces outlet 5; The rotary kiln outlet 2 of preheating rotary kiln 1 is communicated with electric arc furnaces charge door 3.
Further, the utility model also comprises cylinder 8, and cylinder 8 is arranged at below, electric arc furnaces 6 left sides, and the piston rod 9 of cylinder 8 withstands on the position, edge of electric arc furnaces 6.
Advantage of the present utility model: simple in structure, easy-unloading.
