• The development of large diameter scraper basically meets the technological requirements of rolling mill

    Txoj kev loj hlob ntawm loj diameter scraper yeej tau raws li qhov thev naus laus zis yuav tsum tau ntawm dov zeb

    Qhov ua tiav ntawm sab nraud ntawm txoj kab uas hla ntawm cov raj taub raj uas xuas tes xuas tes los ua tsis taus. Yog tias cov embryo tube tuab heev, nws tsis yooj yim kom tau raws li qhov yuav tsum tau muaj ntawm lub tshuab dov. Vim tias txheej txheem sab nraud ntawm lub raj yog tuab heev thiab cov khoom embryo dhau los sib sib zog, nws tsuas yog ua los ntawm cov cuab yeej siv hnyav. Thaum pib, tsuas yog ib lossis ob daim tuaj yeem muab laij tawm tau. Tom qab ntawd, cov haujlwm ua haujlwm tau raug txhim kho nyob rau hauv peb lub tuam txhab kev tsim khoom lag luam. Kev txhim kho ntawm rau, yim daim thiab loj qhov loj ntawm daim tawv nqaij scrapers yog yeej nyob rau hauv txoj kab nrog cov txheej txheem ntawm cov dov zeb xav tau.
