Problems solved by technology

[0003] In the process of pyrometallurgy, ore and coal are added to the smelting furnace, the metal in the ore is extracted and becomes a molten state, and the impurities in the coal and ore form waste slag, and the molten metal flows out from the discharge port, but in the metal When flowing out, the waste slag is easy to flow with the metal, and then block the discharge port
Secondly, because the ore volume is generally larger, it takes longer to restore the metal in the ore, which takes a long time

Embodiment Construction

[0027] The reference signs are: frame 1, stepping motor 11, cutting motor 12, turntable 13, combustion cylinder 2, smelting furnace 3, collecting tank 31, slag retaining ring 32, chute 33, outer gear ring 34, slag outlet 35, cover body 36, outer tube 4, cutter 5, chute 6.

[0028] like figure 1 As shown, a smelting method adopts a fast-melting metallurgical furnace for smelting. The smelting furnace includes a frame 1 and a cutting mechanism and a smelting mechanism arranged sequentially from top to bottom. The cutting mechanism includes a cutter 5, a cutting motor 12 and an outer cylinder. 4. Outer cylinder 4 is positioned at cutter 5 periphery, and cutting motor 12 is fixed on the frame 1 and is positioned at the top of outer cylinder 4, and the output shaft of cutting motor 12 is welded with cutter 5 middle parts. The inner wall of the outer cylinder 4 is integrally formed with an annular rotating groove, and both ends of the cutter 5 are inserted into the rotating groove...

Abstract

The invention relates to the field of metallurgy, and particularly discloses a smelting method. A smelting furnace which can carry out smelting quickly is used for conducting smelting. The smelting furnace comprises a rack, a cutting mechanism and a smelting mechanism. The cutting mechanism comprises a cutter, a cutting motor and an outer cylinder, wherein the cutting motor can drive the cutter torotate. The smelting mechanism comprises a smelting furnace body, a stepping motor and a burning cylinder, wherein the burning cylinder is located on the periphery of the smelting furnace body, and the stepping motor can drive the smelting furnace body to rotate. The smelting furnace body is fixedly provided with a collection tank, the smelting furnace body is internally and fixedly provided witha slag blocking ring, the middle portion of the slag blocking ring protrudes towards the center of the smelting furnace body, and the lower portion of the smelting furnace body is provided with a slag outlet. The smelting method comprises the first step of material mixing, the second step of pre-heating, the third step of smelting, the fourth step of discharging and the fifth step of cleaning. Bymeans of the scheme, metal in ores can be rapidly reduced.

Description

technical field [0001] The invention relates to the field of metallurgy, in particular to a smelting method. Background technique [0002] Metallurgy is the process and process of extracting metals or metal compounds from ores, and using various processing methods to make metals into metal materials with certain properties. There are various methods of metallurgy, among which the traditional metallurgical method is pyrometallurgy, which is a metallurgical process carried out under high temperature conditions. Part or all of the minerals in the ore or concentrate go through a series of physical and chemical changes at high temperatures to form another form of compound or element, which is enriched in gas, liquid or solid products respectively to achieve the metal and gangue to be extracted and other purposes of impurity separation. [0003] In the process of pyrometallurgy, ore and coal are added to the smelting furnace, the metal in the ore is extracted and becomes a molte...
