Production method of plating steel belt for household gas wares

Abstract

Provided is a production method of a plating steel belt for household gas wares. The method comprises the steps that a DC03 hot-rolled pickling coil serves as a raw material, repeated cold rolling is conducted, and then degreasing is conducted; primary annealing is conducted; belt making is conducted, specifically, uncoiling and striping are conducted and burrs are removed; an Ni-Co alloy is electroplated; conventional washing and drying are conducted; physical vapor deposition is conducted; ion implantation is conducted; secondary annealing is conducted; and the plating steel belt is obtained by winding after being naturally cooled to the room temperature. The tensile strength of the steel belt is 500-550 MPa, ductility is 34-38%, the surface roughness is 0.04-0.07 micrometer, the specular reflectance is 99.2-99.7%, and the gloss loss is not more than 0.2% after the steel belt is exposed for 4000 days at the indoor atmosphere environment; and for the steel belt needed by a gas ware panel, the tensile strength is 400-450 MPa, ductility is 42-47%, the surface roughness is 0.02-0.05 micrometer, the specular reflectance is 99.55-99.95%, and the gloss loss is not more than 0.3% after the steel belt is exposed for 3600 days at the indoor atmosphere environment.

Description

technical field [0001] The invention relates to a production method of a steel strip, in particular to a production method of a coated steel strip used for producing household gas appliances. Background technique [0002] Gas appliances generally refer to daily household appliances that use coal gas, liquefied petroleum gas, and natural gas as the main fuel, mainly including gas stoves, water heaters, wall-hung boilers, etc. With the rapid development of the national economy, people's quality of life continues to improve, and the requirements for the safety and cultural taste of household gas appliances are also increasing. Taking high-end stoves as an example, the industry generally uses high-quality stainless steel as raw materials for production, and different parts have different requirements for raw material performance. Because the internal ignition device is close to the fire source, for safety reasons, it is required that the steel used as raw material must have g...

AI Technical Summary

Problems solved by technology

However, there are two obvious deficiencies in high-quality stainless steel: based on the need to achieve product performance, a large amount of alloying elements are added to the raw material steel, which on the one hand leads to a sharp increase in raw material costs; on the other hand, it also causes raw material smelting, rolling, The difficulty of heat treatment and product forming has increased significantly

Although the product has good surface properties, electrical conductivity, and thermal conductivity, the coated steel strip uses the precious metal Au, which is more expensive and difficult to promote for the production of household gas appliances.

In addition, the coated steel strip has low hardness and poor wear resistance

In particular, the Au-Sn binary alloy is composed of many brittle and hard intermediate phases, and the processing and forming properties of the product are insufficient.
