Abstract

The invention provides a six phase electrode electric melting furnace, relating to an electric melting magnesium smelting device, solving the problems of slow temperature rise of furnace temperature, high energy consumption and low yield which exist in current three phase electrode electric melting furnace. In the six phase electrode electric melting furnace, the furnace body is a six-prism body; the six phase electrode is inserted and arranged in the furnace body; the first electrode, the second electrode and the third electrode are arranged in a row with uniform spacing; the fourth electrode, the fifth electrode and the sixth electrode are arranged in a row with uniform spacing; the two rows of electrodes as a whole form a parallelogram; four equilateral triangle hot zones are respectively formed by the first, second, fourth electrodes, the second, fourth, fifth electrodes, the second, third, fifth electrodes, and the third, fifth, sixth electrodes. In the smelting process, the six phase electrode electric melting furnace forms four triangle hot zones, thus achieving concentrated heat, rapid heating of magnesium stones, steady reaction, dramatic lowering of electricity consumption, high speed of temperature rise of furnace temperature which can reach 3500 DEG C, uniform and stable product quality, energy saving and consumption lowering, high yield and good benefit.

Description

Six phase electrode electric melting furnace

Technical field

The invention relates to a kind of fused magnesia smelting equipment.

Background technology

At present, electric-melting magnesium manufacturing enterprise three-phase electrode electric smelter commonly used comes the production electric-melting magnesium, its structure as shown in Figure 1, the electric smelter of this structure only forms a triangle thermal treatment zone by three electrode A, B, C in smelting process, furnace temperature heats up slow, and the highest furnace temperature can only reach 2750 ℃, directly influences product yield and quality, cause electric-melting magnesium produce power consumption high, yield poorly, of poor benefits.

Summary of the invention

In order to solve the problem of above-mentioned existence, the invention provide a kind of power consumption less, six phase electrode electric melting furnace that output is high; The purpose of the invention is achieved through the following technical solutions: six phase electrode electric melting furnace, comprise body of heater, electrode, it is characterized in that: described body of heater is a hexagonal prism, six-phase electrode is inserted in the body of heater, first electrode, second electrode, third electrode equidistantly is placed to a row, the 4th electrode, the 5th electrode, the 6th electrode equidistantly is placed to a row, the whole parallelogram of two row's electrodes, respectively by first electrode, second electrode, the 4th electrode, second electrode, the 4th electrode, the 5th electrode, second electrode, third electrode, the 5th electrode, third electrode, the 5th electrode, the 6th electrode constitutes four equilateral triangle heating regions.

The beneficial effect of the invention: said structure is adopted in the invention, and body of heater is changed into the six phase electrode electric melting furnace of hexagonal prism by original three-phase electrode circle electric smelter.Has following advantage: the first, because six phase electrode electric melting furnace forms four triangle thermals treatment zone in smelting process, make heat concentrate the fast and reacting balance of magnesite heating, stopped to smelt spray stove phenomenon, reduce power consumption greatly, output is produced by one class and was calculated in 10 hours, average hourly output is 1.25 tons, and a ton power consumption does not surpass 2800 degree electricity, compares with the three-phase electrode electric smelter and produces electric-melting magnesium per ton 200 degree that can economize on electricity.The second, six phase electrode electric melting furnace furnace temperature quick heating, furnace temperature can reach 3500 ℃, and thermal conductivity is strengthened in the abundant reagentia of the high favourable raw material of furnace temperature, and reduce electrical property such as electric current leakage value, make uniform in quality stable, the finished product height.Three, compare with three-phase electrode electric smelter traditional handicraft, the six phase electrode electric melting furnace new technology is low to the giobertite grade requirement, impurities removal mass-energy power is strong, percentage of product and the yield rate that can utilize the low-grade giobertite of many impurity to smelt the fused magnesite that all increase, improved the utilization rate of magnesium resource, limited resources are fully utilized.Four, six phase electrode electric melting furnace new technology because of the high sufficient reacting of its furnace temperature, obviously reduces its dust that outwards discharges; Simultaneously,, reduced electrode erosion, made the consumption rate of electrode reduce by 20%, reduced the consumption of material because of the six phase electrode electric melting furnace arc stability is good.In a word, the six phase electrode electric melting furnace new technology is three-phase electrode electric smelter traditional handicraft production electric-melting magnesium relatively, promptly saves the energy, resource, material, improves the quality of products again, output.
