Problems solved by technology

However, many surface treatment methods such as mechanical grinding, chemical treatment, etc. will cause damage to the surface of the product, not only the product specification will be affected, but also the performance of the product itself will be affected.
[0004] Aiming at the shortcomings of ordinary surface-treated products such as easy damage and inconsistent specifications, Publication No. 105088292A discloses a method of copper plating on the metal surface to improve the corrosion resistance and wear resistance of the product without damaging the product surface
However, copper itself is a metal that is easily corroded, and it is easy to form copper rust in a humid air environment, which is also unacceptable in terms of improving product life.

Embodiment 1

[0027] Ingredients: Weigh the raw materials according to the ingredients and mass percentages of the above-mentioned high-strength metal shelves, including Tl: 8%, Si: 1.5%, Ba: 0.15%, C: 0.6%, Co: 6%, Pb: 4%, Sn : 2.5%, Te: 2.5%, the balance is Fe and impurities, where the impurities include P<0.055%, S<0.065%, and O<0.01%.

[0028] Melting: Put the raw materials into an intermediate frequency induction furnace to form alloy steel liquid.

[0029] Forging: Injecting molten alloy steel into a mold to form alloy steel ingots, and then upsetting, elongating, shaping and cooling the alloy steel ingots at 1250°C to obtain alloy steel plates. The specific cooling is: adding 0.5% pertechnetate to the cooling water, and then pour the cooling water from top to bottom on the shaped alloy steel plate, and circulate it many times until the temperature of the steel plate drops to room temperature, during which the cooling water is replenished in time Technetate maintains its concentration.

Abstract

The invention discloses a machining method of a high-strength metal shelf, and belongs to the technical field of metal machining. The machining method of the high-strength metal shelf includes the steps: raw material smelting; forging; forming; surface treatment. The raw material components of the metal shelf comprise, in weight percent, 5-10% of Tl, 1-2% of Si, 0.1-0.2% of Ba, 0.4-0.8% of C, 4-8%of Co, 3-5% of Pb, 1-4% of Sn, 2-3% of Te and the balance Fe and impurities. The impurities comprise, in weight percent, less than 0.055% of P, less than 0.065% of S and less than 0.01% of O. According to the machining method, deformation process is performed in a forged manner, so that grain refinement is facilitated, so that comprehensive performances of the metal shelf are improved, a uniformand compact protection film is formed in a laser surface alloying manner, and the anti-rust capability of the metal shelf is enhanced by sprayed paint.

Description

Technical field [0001] The invention relates to a processing method of a high-strength metal shelf, belonging to the field of metal processing. Background technique [0002] Shelves are widely used as indispensable items in life. The materials of shelves can generally be divided into wood, alloy, and polymer materials. Because of its good strength and hardness, the number of alloy shelves far exceeds that of other materials. At the same time, how to do a good job in metal surface protection is also very important. [0003] Surface treatment is a process of artificially forming a surface layer on the surface of the substrate material that is different from the mechanical, physical and chemical properties of the substrate. The purpose of surface treatment is to meet the product's corrosion resistance, wear resistance, decoration or other special functional requirements. For metal castings, our more commonly used surface treatment methods are mechanical polishing, chemical treatmen...
