[0003] It is reported that the sources of elemental iron that are better and widely used at present are mainly pig iron powder and direct reduced iron powder, as well as briquettes made of cold-rolled thin steel plate scraps produced in the production of car bodies in the automobile and motorcycle industries. Since pig iron powder and direct reduced iron powder have many impurities, the impurities are mainly SiO2, Cr, Cu, Ni, Sb, Nb and Pb and other elements, such quality raw materials are used as reducing agents in chemical and pharmaceutical production. Quality suffers and costs are high
[0004] The thickness of cold-rolled thin steel plate leftovers produced in the production of automobile and motorcycle industries is about 1.5 mm. The resulting briquette is composed of several irregular thin steel plates. The size of the briquetting block is 200mm*200mm*500mm , with a unit weight of about 70kg, this raw material is used as a reducing agent in chemical and pharmaceutical production, and the reaction speed is relatively slow, and the dissolution time is usually about 6-7 hours. Not only will energy consumption be increased during production, but the production cycle is longer, and the unit time Low output, relatively high production cost

Abstract
The invention discloses a preparation method of a steel wire in a waste rubber tire of a car and an application thereof in chemical engineering and pharmacy. The steel wire in the car waste rubber tire can better meet the requirements of chemical engineering and pharmacy enterprises on raw materials compared with raw iron powder, reduced iron powder and a coldly-rolled thin steel plate leftover pressing block; and the source is wide and the market price is lower than that of the raw iron powder, the reduced iron powder and the coldly-rolled thin steel plate leftover pressing block. The production investment is lower and no environment pollution is caused; and the preparation method belongs to reutilization of waste material resources, is more economical and environment-friendly, can greatly improve production costs of the chemical engineering and pharmacy enterprises, and can improve the economic benefit. The application of the steel wire in the car waste rubber tire in the chemical engineering and pharmacy enterprises accords with scientific ideas of energy saving and emission reduction, low carbon and environmental friendliness, which are globally and vigorously advocated; and the steel wire is a very ideal raw material upgraded and updated product of current chemical engineering and pharmacy enterprises of China, even the whole world.
Description
technical field [0001] The invention belongs to the field of chemistry, and in particular relates to the application of a steel wire in automobile waste rubber tires as a reducing agent in chemical industry and pharmacy. Background technique [0002] At present, elemental iron is widely used as a reducing agent in my country's chemical, pharmaceutical and other industries. For example, in the production process of titanium dioxide, in order to reduce ferric ions in the solution to ferrous ions, elemental iron needs to be added as a reducing agent. In the pharmaceutical production process, elemental iron is often used as a reducing agent for synthesis reactions. [0003] It is reported that the sources of elemental iron that are better and widely used at present are mainly pig iron powder and direct reduced iron powder, as well as briquettes made of cold-rolled thin steel plate scraps produced in the production of car bodies in the automobile and motorcycle industries.
