Roll induction umatshini wokuqina

Unyango olushushu lwemiqulu yomsebenzi eqengqelekayo luhlala luthatha ukucima kunye nokuthoba ubushushu obuphantsi, iindlela zokucima ezifana nokucinywa komphezulu wokungeniswa kunye nokucinywa kobushushu obudibeneyo. Injongo kukuphucula ukuxhatshazwa kokugqoka kunye nokuxhatshazwa kwe-peeling of roll. Umqulu oshushu udla ngokusebenza kwindawo yobushushu obuphezulu be-700-800 °C, kwaye umphezulu kufuneka umelane nokungqubana okuqinileyo kwezinto eziqengqelekayo kunye nokufudumeza okuphindaphindiweyo, kunye nokudinwa kwe-thermal ngenxa yotshintsho olukhulu kwiqondo lokushisa lokupholisa. amanzi apholileyo. Emva kokuphuhliswa kwee-hot rolls, i-high-chromium cast iron to semi-high-speed steel kunye ne-high-speed steel yakhethwa kwizinto zabo.
