Complete Equipment For Chromium Slag Refining Furnace ISO9001 Certified

Product Specification

Complete equipment for refining furnace of chromium slag

Technological process of production:

Description of the process:

  The main raw materials of the special refining furnace are calcium-free chromium slag, calcium-vanadium slag, carbonite and silica, which are calculated according to the ingredients of raw materials on site, accurately weighed by an electronic balance according to a certain ratio, and reasonably batted and dried, and then sent to the top silo of the 13.5-meter platform of the electric furnace by a inclined bridge loading trolley.          Through the circular distribution system at the top of the electric furnace, it is put into the top bin, and through the feeding pipe in the furnace, it is continuously sent to the submerged arc melting. The slag and hot metal are discharged through the iron outlet, injected into the hot metal and slag bag, and some of the slag is removed by water quenching method. After the oven is finished, the hot metal package car is opened to the casting stage, after sedation, the scum is lifted to the water quenching slag chute for slag discharge, the remaining hot metal is poured into the ingot mold, the alloy is slightly cooled and pry up, after natural cooling and crushing, the crane is lifted to the iron box, and the cooling is put into the storage.
The flue gas of the electric furnace enters the bag dust collector, is treated, discharged after reaching the discharge standard, and the dust dust is returned to the raw material workshop.

Structure type of equipment:
1) The use of fully water-cooled horizontal jacking hydraulic cylinder pressure ring, so that the copper tile force uniform, balanced and uniform conduction;
2) The use of new water-cooled cable technology and forged copper shingles, water-cooled cable and copper pipe connection selection of button-type connection, which can reduce the contact resistance;
3) The new short network structure of one to one between the transformer outlet and the copper tile makes the equipment more advanced and the operation rate is high;
4) The short-net design uses the three-phase electrode triangular connection method, which has good short-net compensation, low impedance, low three-phase unbalance coefficient, high power factor and significant power-saving effect;
5) Adopt full hydraulic lock, PLC control, to achieve voltage discharge, improve the operation rate of the electrode system;
6) The large current carrying conductor is made of non-magnetic steel, which can greatly reduce the power loss;
7) The insulation system of the entire equipment is at least twice insulated;
8) According to the smelting characteristics of special refining furnaces, the automatic electrode regulator adopts the more mature PLC+ proportional valve automatic regulation technology on steel furnaces at present;
9) The furnace structure adopts a unique furnace form, which greatly improves its reliability (lining life), and the power saving effect is obvious.
Special refining furnaces using the new technology and equipment are currently at the leading level in China.
