Description
Jiangsu Liangyi is professional manufacturer of 1.2327,86CrMoV7 open die forging parts and seamless rolled steel forged rings from china
Following is the shape of 1.2327,86CrMoV7 forging steel material that we could do is:1.2327 Forged Steel round bars square bars Flat bars Rectangles Bars Rods,1.2327,Forged forging steel rings seamless rolled rings,86CrMoV7 Forged Forging Steel Hubs housing shell Sleeves Bushes Bushing Cases Hollow Bars,1.2327 forging forged steel Forged Forging Steel Cold mill work rolls roller straightening rolls roller, back-up rolls Rollers Leveller rolls rollers,86CrMoV7 Forged Forging Steel Discs Disks Blocks plates,1.2327 Forged Forging Steel Pipe Tubes Tubings Piping Shells Casings Case barrels Housings.
1.2327,86CrMoV7 is used as semiconductors in the state of high temperature for the production of forged cold-rolling rolls with barrel diameters up to 700mm, resistance roll shirts, dies and other parts of hot and cold rolling mill. They differ from other tool steels in the chemical composition, which consists of Chromium, Vanadium, high carbon content, and in one species of Molybdenum especially.

FOllowing is manufacturing process flow of 1.2327,86CrMoV7 straightening roll : electrosmelting → external refining → ingot casting → rolling electrode → electrode roughing → esr → ingot casting → expansion hydrogen anneal process → forging → conditioning heat treatment → UT (Ultrasonic Testing)+high macroscopic examination → roughing → modified thermal treatment → semi-finishing → final thermal treatment → precision work → finished product.
Heat treatment way of 86CrMoV7 forging steel rolls is as followings
expansion hydrogen anneal process technology is: go into stove → 880-920 ℃ of insulation → 700-740 ℃ of insulation → stove for≤400 ℃ and be chilled to the 300-500 ℃ of air cooling of coming out of the stove.
spheroidal annealing process is: go into stove → 850-880 ℃ of insulation → 700-740 ℃ of insulation → stove for≤400 ℃ and be chilled to the 300-500 ℃ of air cooling of coming out of the stove.
quenching-and-tempering process is: 890-910 ℃ of oil quenching and 630-650 ℃ of high tempering.
final thermal treatment process is: 960-980 ℃ of line-frequency induction quenched and 200-250 ℃ of low-temperature tempering.
