Nyob rau hauv cov txheej txheem ntawm lub kaum sab xis steel, lwm qhov ib puag ncig ib puag ncig kuj yog qhov tseem ceeb uas cuam tshuam rau nws qhov kev tsim khoom zoo, thiab ntawm ntau qhov chaw sab nraud, qhov kub thiab txias muaj kev cuam tshuam zoo. Yog li, qhov kub thiab txias cuam tshuam li cas rau kev tsim ntawm lub kaum sab xis steel?
Feem ntau, lub kaum sab xis steel forging kub yog to taub raws li qhov siab tshaj plaws tso cua sov kub ntawm cov hlau los yog hlau nyob rau hauv lub qhov cub cua sov. Raws li ib txwm muaj, ua ntej tshem tawm qhov khoob ntawm lub qhov cub cua sov thiab xa mus rau cov khoom siv forging pib forging, qhov khoob muaj qhov kub thiab txias ntawm ob peb degrees mus rau kaum ob degrees raws li qhov loj ntawm qhov khoob, txoj kev thauj cov dawb paug thiab qhov kev ncua deb ntawm lub qhov cub cua sov thiab cov khoom siv forging.
Uas yog hais tias, qhov kub ntawm lub kaum sab xis steel tiag tiag pib forging yog me ntsis qis, yog li qhov kub poob ntawm qhov khoob yuav tsum tau txo kom tsawg li ntau tau ua ntej pib forging. Txij li thaum kub kub ntawm cov hlau yog li ntawm 100-150℃qis dua lub melting point, thiab lub superheating kub yog hais txog 50℃qis tshaj qhov overheating kub, qhov pib forging kub ntawm steel feem ntau yuav tsum tau qis dua lub melting point ntawm 150-200 degree.
Tsis tas li ntawd, cov ntsiab lus carbon muaj qhov tseem ceeb tshaj plaws nyob rau sab sauv forging kub ntawm cov hlau, yog li qhov pib forging kub ntawm lub kaum sab xis steel txo qis nrog qhov nce ntawm cov ntsiab lus carbon, yog li feem ntau qhov pib forging kub txo qis dua nrog qhov nce ntawm cov ntsiab lus carbon, thiab cov ntsiab lus carbon hauv cov khoom siv raw yuav tsum tau tswj.
Los ntawm kev soj ntsuam saum toj no, nws tuaj yeem pom tau tias qhov ntsuas kub xav tau rau lub kaum sab xis steel yog qhov sib txawv thaum nws mus los ntawm cov txheej txheem ntau lawm, yog li tus neeg teb xov tooj yuav tsum tau hloov kho qhov kub thiab txias tas li, txhawm rau xyuas kom meej tias cov hlau tiaj tus zoo dua forged thiab nws zoo dua.
