Oil filler lining plate being lower in surface roughness, smaller in machining allowance and higher in strength, as well as preparation method thereof

Abstract

The invention discloses an oil filler lining plate being lower in surface roughness, smaller in machining allowance and higher in strength. The oil filler lining plate is characterized by comprising the following components in parts by weight: 500-550 parts of limonite, 50-70 parts of siderite, 400-480 parts of pyrite, 10-20 parts of chalcopyrite, 5-6 parts of hydromica, 8-9 parts of malachite, 10-14 parts of maghemite, 5-6 parts of sphalerite, 2-3 parts of cassiterite, 1-2 parts of jamesonite, 5-6 parts of chalcocite, 6-7 parts of ilmenite, 2-3 parts of wolframite, 3-4 parts of tantalorutile, 20-30 parts of copper-nickel sulfide ore and 200-260 parts of a nickel ore biological metallurgy catalyst. According to the oil filler lining plate disclosed by the invention, the nickel utilization ratio is improved by adopting the biological metallurgy technology, and the mechanical properties of parts are improved by adopting a plurality of machining processes.

Description

Technical field [0001] The invention relates to the field of machining of mechanical parts, in particular to a fuel filler liner with reduced surface roughness, reduced machining allowance and improved strength, and a preparation method thereof. Background technique [0002] Since the emergence of machinery, there have been corresponding mechanical parts. But as a discipline, mechanical parts are separated from mechanical structure and mechanics. With the development of the machinery industry, the emergence of new design theories and methods, new materials and new processes, mechanical parts have entered a new stage of development. Theories such as finite element method, fracture mechanics, elastohydrodynamic lubrication, optimization design, reliability design, computer-aided design (CAD), solid modeling (Pro, Ug, Solidworks, etc.), system analysis and design methodology have gradually For the research and design of mechanical parts. To better realize the integration of multi...

Problems solved by technology

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
