Kub -}}}} poll1mov alloy steel round pib nrog melting cov khoom siv raw hauv lub tshuab hluav taws xob tsim hluav taws xob. Lub Molten Steel yog ces muab pov rau hauv cov tsiaj ua haujlwm. Cov nyiaj no rov qab ua kom haum rau qhov ntsuas kub uas haum, ib txwm muaj qib 1000 degree, thiab dhau los ntawm ib qho cross- seem thiab tsim cov duab puag ncig.
Cov qauv tsim rau 12cr1mov tsom rau kev tswj tshuaj lom neeg. It must contain specific amounts of chromium (0.9 - 1.2%), molybdenum (0.25 - 0.35%), and vanadium (0.15 - 0.30%), along with carbon (0.08 - 0.15%) and other elements. Cov khoom siv neeg kho tshuab kuj tseem nruj me ntsis saib xyuas. Lub zog tensile yuav tsum yog tsawg kawg yog 490 MPa, thiab cov txiaj ntsig lub zog tsawg kawg 245 MPa. Tsis- Qhov kev sim siab, xws li ultrasonic thiab iCocegraphic xeem, feem ntau nqa tawm los xyuas cov khoom siv sab hauv. Kev kho cua sov tom qab dov tawm, zoo li norolling thiab templiging kom ua tiav micrastred micros {14} -}}}}}} kub ripelines.
