Raws li cov txheej txheem ntau lawm, seamless steel kav yuav muab faib ua kub dov seamless steel kav, kub-expanded seamless steel kav, thiab txias-draw seamless steel kav.Plaub pawg ntawm txias-dov seamless steel raj.

Kub dov seamless steel yeeb nkab yog ib puag ncig steel uas tau tho rau hauv lub raj khoob los ntawm lub tshuab tho thiab tom qab ntawd dhau los ntawm lub tshuab kub dov los teeb lub raj tsis muaj qhov tshwj xeeb sab nraud txoj kab uas hla los ua rau kub dov seamless. cev steel.Cov txheej txheem yog qhov yooj yim thiab tus nqi qis, tab sis qhov ntsuas qhov tseeb tsis siab.

Kub-expanded seamless steel kav yog tsim los ntawm kev siv seamless steel yeeb nkab blanks los yog tiav seamless steel kav yuav tsum tau hlawv kom kub siab tshaj 1050 degrees nyob rau hauv ib tug hluav taws xob rauv nrog ib tug alloy core taub hau kom nthuav mus rau ib tug tej yam sab kab uas hla sab hauv.Tom qab tau nthuav dav rau hauv cov yeeb nkab thermally nthuav dav seamless steel yeeb nkab, phab ntsa thickness yog nyias dua li cov khoom siv raw, qhov ntev yog luv luv, thiab sab nraud yog loj dua.

Cold drawn seamless steel yeeb (astm a53) yog seamless steel yeeb nkab uas yog tsim los ntawm kos ib seamless steel yeeb nkab dawb los yog tiav seamless steel yeeb nkab los ntawm pwm ntawm lub tshuab txias txias.Nws coincides nrog cov txheej txheem kub expansion.Cov yeeb nkab uas tau kos tiav yog ntev dua li cov khoom siv raw, cov phab ntsa tuab yog nyias, thiab sab nraud yog me dua.Cov txheej txheem kos duab tsis xav tau cua sov, thiab nws tuaj yeem tsim nyob rau hauv chav tsev kub, thiab nws tuaj yeem rov ua dua.Qee lub sij hawm nws tsis tsim nyog rau anneal.

Cov txheej txheem txias dov kuj tseem tsim nyob rau hauv chav tsev kub zoo li cov txheej txheem kos duab txias, tab sis lub tshuab txias dov yog txawv ntawm lub tshuab txias txias.Lub tshuab nqus tsev txias yog tsim los ntawm pwm, thiab lub tshuab txias dov yog maj mam tsim los ntawm cov pwm, yog li cov txheej txheem txias dov yog tsim Nws qeeb dua li cov txheej txheem txias txias.
