Tall wear-resisting Leng Zunmo provides process of steel heat treatment

Tall wear-resisting Leng Zunmo provides steel is tall carbon tall chromium steel commonly, have on behalf of steel grade: CR12, Cr12MoV, Cr12Mo1V1, Cr12W, Cr12V, LD(7Cr7Mo2V2Si) , ER5(Cr8MoWV3Si) , GM(9Cr6-W3Mo2V2) . Above steel is Lai body steel for the most part, have in the organization many in all brilliant carbide, after vacuum quenchs, have a large number of in all brilliant carbide exists, wearability is tall, bear the weight of muscularity, often use at making the cold working that works below tall wear-resisting condition use a pattern. Portant; MAX-WIDTH: 100%; PADDING-BOTTOM: 0px; PADDING-TOP: 0px; PADDING-LEFT: 0px; MARGIN: 0px; LINE-HEIGHT: 26px; PADDING-RIGHT: 0px; TEXT-INDENT: The heat treatment that 32px"> chooses this material correctly is plain bearing liner makes medium key. Ever was opposite in polyvinyl alcohol (the plain bearing liner of the job in PVA) size made vacuum low oil is low a craft and statistic of heat treatment distortion, the plain bearing liner in the article is in polyester (of the job in PET) size, use temperature is higher, in 350 ℃ left and right sides, the use temperature of size of prep above PVA (be in about 100 ℃ ) , plan to use Gao Cuigao to answer heat treatment craft to this plain bearing liner. The treatment working procedure of plain bearing liner forgings to issue makings → → ball changes anneal → machine to machine → vacuum to quench temper → grinding. The microstructure after this experiment changes anneal and Gao Cuigao to answer craft to handle to ball of classics of plain bearing liner and hardness and quantity of heat treatment distortion had observation and test, so that be,this kinds of dimension before the craft of material is adjusted and quenching will machine allowance to provide reference henceforth. At present Cr12 kind the 50% above that material heat treatment occupies Leng Zunmo to have treating capacity, grasp the heat treatment technology with this kinds of different material and microstructure feature and distortion pattern, the production of pattern of the industry in be being produced to scientific research has active direct sense.

Moving condition is slashing, workmanship is complex, the Cr12MoV steel of production plain bearing liner is in except the requirement below constant temperature condition outside the hardness that keeps taller, still must have wear-resisting caustic, anti-corrosive, fight oxidation, good measure stability and better can be waited for by processability.
