Rear door left hinge reinforcing plate with good-corrosion-resistance easy-to-weld welding zone and preparation method thereof

Abstract

The invention discloses a rear door left hinge reinforcing plate with a good-corrosion-resistance easy-to-weld welding zone. The rear door left hinge reinforcing plate is characterized by comprising the following components in parts by weight: 500-550 parts of siderite, 400-480 parts of alferric minerals, 10-20 parts of chalcocite, 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, 2-3 parts of scheelite, 5-6 parts of bonamite, 3-4 parts of tantalorutile, 2-3 parts of ilmenite, 20-30 parts of pentlandite and 200-260 parts of a nickel ore biological metallurgical catalyst. The rear door left hinge reinforcing plate is good in wear resistance and is resistant to corrosion; and the easy-to-weld welding zone is good in corrosion resistance.

Description

technical field [0001] The invention relates to the field of mechanical parts processing, in particular to a rear door left hinge reinforcing plate with good corrosion resistance and easy welding in the welding zone 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 construction 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 research and design of mechanical parts. To better realize the synthesis o...

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
