Seamless steel yeeb txoj kev paub txog kev paub
Kev seamless steel yeeb nkab yog ua los ntawm steel ingot los yog khoom tube dawb paug ntawm perforation, thiab tom qab ntawd ua los ntawm kub dov, txias dov los yog txias daim duab. 45 seamless steel yeeb nkab yog ib hom khoom siv hlau, uas yog qhov khoom zoo siab carbon steel, ntau ntau cov pwm ntau lawm yuav siv nws los ua pwm hlau. Lub seamless steel yeeb nkab yog ua los ntawm cov pa kub lossis hlau hlau, thiab kub kub thiab txias rov qab (teeb duab). Lub welded steel yeeb nkab yog tsim los ntawm kev vuam lub phaj steel dov rau hauv ib lub tubular zoo los ntawm ib qho chaw seam los yog ib lub voj kab sib chaws. Raws li txoj kev tsim, nws tseem muab faib ua txuas rau hauv lub voj hlau txuas rau kev siv cov dej khov qis rau cov qis, cov hlua hluav taws xob, cov hlua fais fab txuas, cov hlua fais fab, thiab cov zoo li. Seamless steel kav yuav siv tau ntau hom kua, roj kav, thiab cov zoo li. Welded kav yuav siv tau rau cov kav dej, roj kav, cua sov kav, thiab lwm yam. Los ntawm cov caliber, <φ76, accounting="" rau="" 35%,=""><φ159-650, accounting="" rau=""> Nyob rau hauv cov nqe lus ntawm ntau yam, general-hom kav dej yog 1.9 lab tons, accounting rau 54%; roj kav yog 760,000 tons, accounting rau 5.7%; hydraulic khoom thiab precision kav dej yog 150,000 tons, accounting rau 4.3%; steel hlau, cov kav dej thiab cov kav dej yog 50,000 yuan. Tons, accounting rau 1.4%.
Cov khoom siv rau cov dov seamless steel yeeb nkab yog ib cov kab uas tsis muaj cav, thiab lub khob tob hauv qhov tob tob hlais muab hlais ntev li ntawm 1 m ntawm ib lub tshuab txiav, thiab xa mus rau lub cub tawg kom sov los ntawm kev siv txoj hlua. Lub billet yog pub rau hauv ib lub cub tawg thiab rhuab mus rau ib tug kub ntawm kwv yees li 1200 ° C. Cov roj yog hydrogen lossis acetylene. Kev tswj kom sov kub yog qhov teeb meem tseem ceeb. Tom qab cov kab txiav tawm, nws tau raug mus rau qhov chaw ntawm lub qhov xuas nrig ntaus. Qhov ntau tshuab tshuab ntxhua khaub ncaws ntau yog ib qho kev sib txuas rau cov tshuab xauv tshuab. Qhov tshuab lub tshuab no muaj qhov ua tau zoo tshaj plaws, muaj cov khoom zoo, loj diameter ntawm perforation thiab tuaj yeem hnav ntau hom hlau. Tom qab kev pleev xim tag, cov kab thom khwm yog qhov rov qab los, khov los yog rho tawm ntawm peb qho yob. Tom qab extrusion, lub raj yuav tsum sizing. Lub tshuab sizing yog tig los ntawm kev kub ceev los ntawm kev siv lub thom me ntsis mus rau hauv cov tub ntxhais hlau ua ib lub yeeb nkab hlau. Lub puab inch ntawm lub yeeb nkab steel yog txiav txim siab los ntawm txheej diameter ntawm lub sizing tshuab xyaum me ntsis. Tom qab cov yeeb nkab txhuam tau, nws nkag mus rau hauv lub thawv txias thiab txias dua los ntawm cov dej tsuag. Tom qab cov yeeb nkab yog txias, nws yog straightened. Tom qab cov yeeb nkab hlau ncaj, nws raug xa mus rau ib lub tshuab hlau nyiag hluav taws xob (los yog dej siab sim) los ntawm ib txoj hlua kev siv rau kev haus kom paub meej. Yog tias muaj kab nrib pleb hauv cov yeeb nkab, cov npuas thiab lwm yam teeb meem yuav raug kuaj xyuas. Tom qab kev soj ntsuam ntawm cov yeeb nkab hlau, nws yuav tsum ua tib zoo xaiv los ntawm txhais tes. Tom qab kev kuaj xyuas cov yeeb nkab zoo, cov xim muaj phomed nrog tus naj npawb, specification, ntau cov batch tooj, thiab lwm yam. Nws yog hoisted rau hauv lub tsev rau khoom los ntawm lub crane.
