Nut connecting piece made from high-nickel alloy material and manufacturing method of nut connecting piece

Abstract

The invention discloses a nut connecting piece made from a high-nickel alloy material. The nut connecting piece made from the high-nickel alloy material is characterized by comprising, by weight, 500-550 parts of siderite, 300-310 parts of pyrite, 10-12 parts of asbestos ores, 8-9 parts of bornite, 1-2 parts of smithsonite, 7-8 parts of ilmenite, 30-40 parts of boehmite, 4-5 parts of galena, 4-6 parts of tantalum rutile, 3-4 parts of nontronite, 2-3 parts of hydromica and 10-11 parts of violarite. According to the nut connecting piece made from the high-nickel alloy material, the ores are pre-processed through an acid leaching technology and a pressure leaching technology, so that the extraction efficiency of trace metals in low-grade ores is improved, the purity of trace alloys in the alloy material is improved, and the material quality of parts is improved.

Description

technical field [0001] The invention relates to the field of machining of mechanical parts, in particular to a nut connector made of a high-nickel alloy material and a preparation method thereof. Background technique [0002] As the foundation of the automobile industry, auto parts are a necessary factor to support the sustainable and healthy development of the automobile industry. In particular, the current independent development and innovation in the auto industry, which is in full swing, requires a strong component system to support it. Automobile self-owned brand and technological innovation need parts and components as the basis, and the independent innovation of parts and components will generate a strong impetus to the development of the whole vehicle industry. Without the support of a strong component system, it will be difficult for independent brands to grow stronger.

Problems solved by technology

[0003] During the processing of auto parts, the key to the problem affecting the quality is the material of the product. Therefore, in the casting process, whether high-quality steel materials can be obtained is the key. The casting technology in the prior art has a lot of smelting impurities, which leads to the The strength does not meet the needs, and it causes a waste of ore and a waste of energy

[0004] In addition, trace metals such as nickel metal are difficult to extract, the extraction rate is also low in efficiency, and the utilization rate of ore is low, resulting in waste of raw materials in the production and processing process, and it is difficult to guarantee the quality of cast products. Central South University published in March 2011 A doctoral dissertation "Research on the Theory and Technology of Sulfuric Acid Leaching of Low-grade Nickel Laterite Ore and the Comprehensive Utilization of Leach Slag" pointed out that with the rapid growth of my country's economy, the growth rate of nickel consumption has reached an average annual growth rate of more than 25% in recent years, and has remained unchanged. It has become the world's largest nickel consumer, but the self-sufficiency rate of nickel resources is less than 30%. Accelerating the development of international nickel resources is the key to solving the problem of insufficient nickel resources in my country

In this paper, aiming at the mineral characteristics of low-grade nickel laterite ore in different layers in a nickel laterite deposit in a mining area in Southeast Asia, a new hydrometallurgical process was chosen to study the theory and technology of comprehensive extraction of valuable metals such as nickel, cobalt, and iron. The clean and efficient treatment of ore provides a reliable basis, but the paper only gives the nickel extraction process, and does not give perfect guidance for the actual mechanical processing application in the later stage
