Motheo wa moqolo wa morago ke go thekga moqolo wa mošomo, wo o ka fokotšago bophara bja moqolo wa mošomo le go godiša go tia ga moqolo wa mošomo ka go kgoma seripa sa go kgokologa. roll ya morago ke karolo ya bohlokwa tšhilong ya go kgokologa, yeo e šomišwago go thekga roll ya mošomo goba moqolo wa magareng go thibela go koba le go ama dimelo tša godimo, dimelo tša godimo tša go koba le boleng bja go swana le bja boleng. Thata go swana, tebileng thatafatsa lera la moqolo 'mele, matla a molemo le thata ya moqolo molala le 'mele le 'mele . boleng litšobotsi tsa back-up meqolong e phahameng apara ho hanyetsa, molemo spalling ho hanyetsa le matla kotsi ho hanyetsa.
The morao-up moqolo ke karolo ea bohlokoa ka rolling tšilo, e leng e sebediswa ho tšehetsa mosebetsi moqolo kapa moqolo mahareng ho thibela mosebetsi moqolo ho tloha koba le ama dipholo tsa poleiti le hlobolisa . boleng litšobotsi tsa back-up moqolo ke phahameng holim'a thata, molemo thata junifomo, tebileng thatafala lera la moqolo 'mele le thata ea moqolo le 'mele le 'mele le 'mele le 'mele le 'mele le 'mele le 'mele, Kganetšo le go ganetša kotsi ka maatla. Ka tlhabollo ya tšhilo ya go tonya ya go tonya le ya go fiša go leba lebelo le legolo, tekanyo ye kgolo le go nepagala mo go phagamego, nyakego ya di-back-up roll e bile e oketšega. go tšwa go dinyakwa tša meqolo ya morago ya go tonya le ya go fiša ya go sepela ka morago go dilo tše di bonagalago, go kgokologa ga mmele ka thata, botebo bja legato le le thatafetšego le kgatelelo ya go swana le ya go šoma ya go swana le ya tšhipi ya go swana le ya tšhipi ya go swana le ya tšhipi. back-up roll, the forged steel back-up roll has the characteristics of uniform material, better wear resistance and anti-spalling. Large forged steel back-up roll is a high value-added product, because of its high technical requirements, complex process, difficult manufacturing, production process, long cycle and other reasons, only a few enterprises in China can produce, its output can not meet the market demand, resulting in modern cold and hot tandem rolling mill enterprises used large forged steel back-up roll e swanetše go ithekga ka ditšweletšwa tša ka ntle.
