Abstract
本发明马氏体不锈钢片综的热处理，原材料为带材，热处理过程为连续作业，在氨分解的保护气氛中进行加热，紧接着在带有水冷压板中进行淬火，再在回火后经过拉辊进行定型，最后再进行冲制成型。或者采用在其他还原气氛中加热。淬火加热温度范围为970-1080℃。本发明也适用于其它马氏体不锈钢带材的热处理。The heat treatment of the martensitic stainless steel sheet heald of the present invention, the raw material is a strip, and the heat treatment process is a continuous operation, heating is carried out in a protective atmosphere of ammonia decomposition, followed by quenching in a water-cooled pressing plate, and then after tempering, it is drawn The rollers are shaped and finally punched into shape. Or use heating in other reducing atmospheres. The quenching heating temperature range is 970-1080°C. The invention is also applicable to the heat treatment of other martensitic stainless steel strips.
Description
What the present invention relates to is a kind of Flat Steel Heald material hot treatment, especially a kind of thermal treatment that is used for the martensitic stainless steel sheet of high speed water jet loom.The metallic substance thermal treatment class field that belongs to textile machinery.
Flat Steel Heald in the technical background is used existing history for many years, is particularly useful for the Flat Steel Heald of high speed water jet loom, because wearing and tearing and anti-corrosion problem, all the year round, the professional is devoted to material and heat treated research.Find that through literature search existing part document mentions that its Flat Steel Heald is to make of stainless steel, Grobinox and Draw stainless steel Flat Steel Heald are wherein arranged, but its price is still high.Domestic now using through the austenitic stainless steel of cold working hardening made Flat Steel Heald, but its wear resistance and work-ing life are lower.Utilize Martensite Stainless Steel to be made into Flat Steel Heald, and it is heat-treated,, do not find the thematic literature introduction of this respect in literature search fashion to obtain good wear resistance and solidity to corrosion.
The objective of the invention is to overcome deficiency of the prior art, proposed the heat treated new technology of martensitic stainless steel sheet, improved its work-ing life significantly.
Technical scheme of the present invention mainly is to utilize the martensitic stainless steel belt material through specific heat treatment to make Flat Steel Heald, in order to use properties and the work-ing life of improving martensitic stainless steel sheet.Its thermal treatment process embodiment is as follows: the starting material Martensite Stainless Steel is a band; heat treatment process is for working continuously; its flow process is: band heats in the protective atmosphere that ammonia decomposes; and then in having the water-cooled pressing plate, quench; after tempering, finalize the design again, perhaps adopt in reducing atmosphere and heat by withdrawing roll.Quenching temperature can be controlled in 970-1080 ℃.Carry out punch forming after the band thermal treatment again.
The present invention has significant effect and substantial progress, and its wear resistance improves more than 2 times than austenitic stainless steel Flat Steel Heald, and hardness has very strong practical value at HV460-600.
Further describe below with reference to embodiment:
Embodiment one:
Band heats in the protective atmosphere that ammonia decomposes, and temperature is 970 ℃, carries out quenching and tempering again.Last impact briquetting.To be its wear resistance of HV460 improve 2 times than austenitic stainless steel Flat Steel Heald to hardness, solidity to corrosion through salt-fog test greater than 96 hours.
Embodiment two:
Band heats in the protective atmosphere that ammonia decomposes, and temperature is 1000 ℃, carries out quenching and tempering again.Last impact briquetting.Hardness reaches HV530, and its wear resisting property improves more than 4 times than austenitic stainless steel Flat Steel Heald, solidity to corrosion through salt-fog test greater than 72 hours.
Embodiment three:
Band heats in the protective atmosphere that ammonia decomposes, and temperature is 1080 ℃, quenches then and tempering.Last impact briquetting.Hardness reaches HV600, and its wear resisting property improves more than 5 times than austenitic stainless steel Flat Steel Heald, solidity to corrosion through salt-fog test greater than 48 hours.
