Product Description
Feature
Working principle
Specification
Sponge iron ore is one of the primary iron ore deposits. It is a red natural multi mineral mixture with hydrous iron oxide as the primary component. Its iron content is not high, so it is a non essential iron ore. The hematite powder with particle size of less than 10mm and moisture content of less than 15% is mixed with pulverized coal of 0.8 to enter the rotary kiln. The drying, magnetization and desulfurization process of hematite are completed in the same reverse kiln, and the speed of reverse kiln is 0.8 rpm; The flame temperature and flame shape in the sponge iron rotary kiln should be adjusted frequently to meet the needs of practical production.
1. Support equipment: the main shaft layout is selected, and active temperature measurement equipment and electric heating equipment are set, with movable supports for selection.
2. Block wheel equipment: divided into mechanical wheel and hydraulic thrust block wheel. The hydraulic block wheel equipment is equipped with a hydraulic control system.
3. Transmission equipment: equipped with single transmission or double transmission. DC motor or variable frequency adjustable speed motor controls the speed, which is reliable, energy-saving and efficient.
4.High quality materials are used for production, and the operation parameters are reasonably designed. Therefore, while ensuring the better quality of the equipment, its operation is more stable, the failure rate is reduced, and the service life is extended by more than 5 times;
5.Fully responding to the call of "green environmental protection", the equipment adopts advanced design idea to basically control dust and noise pollution within the specified range.
(1) The raw material (dolomite) is crushed by crusher to qualified material (30-40mm).
(2) It is sintered in a rotary kiln and calcined into calcined white.
(3) It is cooled by a cooler.
(4) Then it is ground into powder by ball mill.
(5) Then it is pressed into a ball by a ball pressing machine.
(6) After crushing, it is evenly mixed with ferrosilicon powder (containing 75% silicon) and fluorite powder (containing gaf2)=95% to form pellets.
(7) Put it into a heat-resistant stainless steel reduction tank, put it in a reduction furnace, and reduce it at 1200-1250 ℃ and 1.33pa vacuum to produce crude oil.
(8) After flux refining, ingot casting and surface treatment, the finished magnesium ingot is obtained.
