Abstract
The present invention relates to a heat treatment method for martensitic stainless steel heddle. The present invention uses strips as raw materials, and the heat treatment process is in a continuous operation mode. The raw materials are heated in a protective atmosphere decomposed by ammonia, and then the raw materials are quenched in a press plate with water cooling function; after tempering, the raw materials are shaped by pull rollers; finally, the shaped raw materials are punched for molding. The raw materials can also be heated in other reducing atmosphere, and the temperature range for quenching heating is 970 to 1080 DEG C. The present invention is also suitable for 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.
