Sintering recovery device and process for industrial metal scraps

Abstract

The invention relates to the technical field of sintering and recycling devices for metal scraps, in particular to a sintering and recycling device and process for industrial metal scraps, and provides the following scheme that the sintering and recycling device comprises a base, a first supporting plate and a second supporting plate are fixedly connected to the top face of the base, and a first conveying device is arranged above the first supporting plate; the bottom of the first conveying device is fixedly connected with a first rod, a second groove is formed in the top face of the first supporting plate, the first rod is located in the second groove and slidably connected with the second groove, a third spring is arranged between the bottom end of the first rod and the bottom face of the second groove, and a second conveying device is arranged above the second supporting plate. A third rack is fixedly connected to the bottom of the second conveying device, a first groove is formed in the top face of the second supporting plate, and the first conveying device is matched with the second conveying device. The purpose of preparing a flux mixture with a certain mass according to the mass of the nickel-chromium-iron waste is achieved.

Description

Technical field [0001] The present invention relates to the field of sintering recovery device for metal scrap, in particular a sintering recovery device and process for industrial metal scrap. Background [0002] China's steel production has ranked first in the world, the demand for stainless steel and production capacity has also increased significantly, steel must contain more than 16% of chromium, more than 8% nickel content, chromium and nickel is the basic additive element of the production of stainless steel, China needs to produce a large number of ferrochrome and ferronickel every year, steel companies in the process of producing and processing metal parts will produce some metal scrap containing nickel, chromium, iron, need to recycle these scraps, generally are these wastes and coke powder and other flux mixture mixed balling, put into the sintering furnace for calcination recovery , in the mixing of the waste and coke powder and other flux needs to be mixed in accord...

AI Technical Summary

Problems solved by technology

[0002] my country's steel production ranks first in the world, and the demand and production capacity of stainless steel have also increased significantly. Steel must contain more than 16% of chromium and more than 8% of nickel. Chromium and nickel are basic additive elements for the production of stainless steel. my country needs to produce a large amount of Ferrochromium and ferronickel. Steel companies will produce some metal scraps containing nickel, chromium, and iron during the production and processing of metal parts. These scraps need to be recycled and processed. Generally, these scraps are mixed with coke powder and other fluxes. After mixing and pelletizing, put it into the sintering furnace for calcination and recovery. The waste material needs to be mixed with coke powder and other fluxes according to a certain ratio. Generally, technicians are required to make ingredients according to the quality of the waste material. Because the waste material produced each time The amount is not fixed, and it is necessary to manually weigh the ingredients before recycling and sintering, which is relatively cumbersome. For this reason, the present invention proposes a sintering recovery device and process for industrial metal waste
