1. Tshem tawm Oxides thiab impurities los ntawm cov hlau kub
Cov txheej txheem steel zeb ntau lawm ua rau muaj ntau ntawm cov hlau kub kub oxides thiab impurities. Yog tias cov oxides thiab impurities tsis raug tshem tawm tam sim ntawd, lawv yuav cuam tshuam nrog cov txheej txheem dov, ua rau tsis sib xws los yog tsim cov nplai ntawm qhov chaw. Yog li ntawd, ua ntej dov, kub hlau oxides thiab impurities yuav tsum tau muab tshem tawm kom huv si.
2. Tswj lub Rolling Kub
Kev tswj qhov kub ntawm cov hlau yog qhov tseem ceeb. Yog hais tias qhov kub dov siab dhau lawm, nws tuaj yeem yooj yim ua rau qhov tsis sib xws ntawm qhov zoo lossis cov qauv tsis ruaj khov. Yog tias qhov kub dov qis dhau lawm, cov nyhuv dov yuav raug cuam tshuam. Yog li ntawd, lub dov kub yuav tsum tau tswj kom zoo thaum lub sij hawm dov txheej txheem.
3. Khaws cov Rollers huv si
Rollers yog cov cuab yeej tseem ceeb tshaj plaws hauv cov txheej txheem steel dov. Yog hais tias impurities los yog ntxhib nto ntawm cov chais yog tam sim no, lawv yuav cuam tshuam rau qhov zoo thiab nto tiav ntawm cov hlau. Yog li ntawd, cov rollers yuav tsum tau ua kom huv si, tsis tu ncua tshuaj xyuas kev puas tsuaj, thiab khaws cia kom sai.
4. Saib xyuas Rolling Parameters
Rolling parameters xa mus rau cov tsis xws li quab yuam, ceev, thiab yob qhov sib txawv thaum lub sij hawm dov. Mastering cov kev txwv no tuaj yeem ua kom cov dov zoo thiab qhov chaw tiav. Yog li ntawd, thaum lub sij hawm dov txheej txheem, cov dov tsis yuav tsum tau saib xyuas ntau zaus thiab kho raws sijhawm.
