Seamless kavyog tsim los ntawm lub raj blanks ntawm ntau yam specifications los ntawm high-temperature extrusion, txias, annealing, xov thiab lwm yam txheej txheem. Nws yog ib qho ntawm plaub qhov loj tsim steel ntau yam hauv kuv lub teb chaws. Nws yog tsuas yog siv rau kev thauj cov kua dej xws li dej, roj, roj, roj, thee, thiab lwm yam thiab rau cov kav dej hauv cov vaj tsev. Nws tseem tuaj yeem siv los tsim cov qauv carbon hauv cov khoom lag luam hnyav xws li tsheb, tsheb laij teb, cov khoom siv hydraulic, thiab cov tshuab tsuas. Cov kav dej thiab cov kav dej alloy. Seamless steel kav yog dav siv nyob rau hauv roj av, tshuaj lom neeg kev lag luam, hluav taws xob fais fab, shipbuilding, aerospace, nuclear kev lag luam, lub teb chaws tiv thaiv kev tsim kho thiab lwm yam teb. Seamless steel yeeb nkab muaj qhov hollow seem, uas tuaj yeem txo qhov cohesion ntawm cov khoom, yog li txo kev sib txhuam; Nyob rau tib lub sijhawm, nws muaj cov thermal conductivity zoo thiab thermal conductivity, yog li nws kuj tau siv dav hauv kev tsim tsheb, tsheb laij teb, cov khoom siv hydraulic, kev ua tshuab, thiab lwm yam. Cov kav dej sab nraud thiab cov kav dej rau cov tshuab thiab cov khoom siv.

1. Cov kav dej seamless tuaj yeem ua tiav raws li qhov xav tau sib txawv thiab tau siv dav hauv kev tsim cov khoom siv thiab cov khoom siv tshuab.

Piv txwv li, lub tsheb cav thiab cov tshuab kis tau tus mob yog cov khoom siv high-precision nrog lub hom phiaj tshwj xeeb. Lawv yuav tsum muaj qhov raug zoo kom ua tau raws li cov qauv tsim. Hauv kev lag luam tsheb, tsheb kauj vab iav feem ntau cuam tshuam los ntawm kev ua haujlwm hnyav. Qhov zoo ntawm lub kauj tsheb yuav tsum muaj kev ua haujlwm siab. Yog li ntawd, kev tsim cov khoom zoo li no yog qhov nyuaj heev. Tom qab xyoo ntawm txoj kev loj hlob, peb lub teb chaws tam sim no muaj peev xwm tsim high-precision seamless steel kav.

2. Cov txheej txheem ntawm cov kav dej seamless tuaj yeem muab faib ua cov kav dej kub-kuav los tiag, txias-kuav los yog txias-draw (extruded) steel kav, uas tuaj yeem ua tiav rau qhov ntev raws li cov neeg siv xav tau.

Cov ntaub ntawv tuaj yeem muab faib ua: carbon structural steel kav, hlau alloy lossis stainless hlau, tooj liab thiab lwm yam tsis-ferrous hlau structural hlau kav thiab cov kav hlau tsis muaj nuj nqis; Raws li kev siv sib txawv, lawv tuaj yeem muab faib ntxiv rau hauv: roj av tawg cov kav dej, xa cov kav dej, cov kav dej tshuaj, cov kav dej steel, cov kav dej siab siab thiab cov kav dej tshwj xeeb seamless steel yeeb nkab ua los ntawm cov khoom tsis muaj nqi lossis hlau, thiab lwm yam. Kev ua haujlwm kub ntawm 20 # seamless steel yeeb nkab yog nruab nrab ntawm -40 ~ 350 ℃; Raws li nws cov tshuaj muaj pes tsawg leeg, nws tuaj yeem muab faib ua amorphous carbon structural yeeb nkab dawb paug thiab dov seamless round yeeb nkab. Feem ntau siv ntau yam ntawm seamless round kav dej muaj xws li: carbon structural kav (xws li roj laum kav, tsheb kis tau tus mob shafts, thiab lwm yam), alloy structural kav (xws li high-pressure fertilizer steel kav, roj av cracking steel kav, high-pressure boiler steel. cov kav dej, thiab lwm yam), cov kav hlau tsis tshua muaj hlau thiab cov kav hlau tshwj xeeb. Lub hom phiaj steel kav, thiab lwm yam; Raws li cov tshuaj muaj pes tsawg leeg, lawv tuaj yeem muab faib ua cov kav dej acid-resistant seamless steel kav; Raws li cov duab thiab qhov loj me, lawv tuaj yeem muab faib ua cov raj square, round tubes, rectangular raj, thiab cov raj tshwj xeeb.

Kev lag luam xav tau rau cov kav dej seamless steel kav tsis muaj zog. Nyob rau hauv cov nqe lus ntawm cov khoom muag: domestic steel mills yog destocking sai sai, tab sis kuj muaj ib tug tej yam khoom muag siab. Tsis tas li ntawd, vim muaj kev cuam tshuam ntawm kev tiv thaiv ib puag ncig thiab kev txwv kev tsim khoom, qhov kev tsis sib haum xeeb ntawm kev ua lag luam thiab kev xav tau tsis yog qhov tseem ceeb, thiab chav rau tus nqi nce yog txwv.

3. Seamless kav yuav tsim los ntawm kub dov los yog txias kos duab thiab ces welded.

Thaum siv cov kav dej seamless steel rau kev siv tshuab, lawv yuav tsum ua tiav raws li cov lus qhia tshwj xeeb, qhov ntev, cov txheej txheem thiab cov ntaub ntawv teev tseg hauv cov duab kos, thiab kev kho saum npoo yuav tsum tau ua raws li cov cai ua ntej vuam. Direct arc vuam tsis raug tso cai. Lub tshav kub tsim thaum lub tshav kub arc loj tuaj yeem yaj lub vuam hlau thiab txo qhov zoo ntawm qhov vuam. Ua ntej vuam, qhov zoo ntawm cov vuam yuav tsum tau ua tib zoo xyuas thiab tsis muaj kev puas tsuaj yuav tsum tau ua. Thaum muaj qhov tsis xws luag ntawm cov welds, tsis muaj kev kuaj xyuas qhov tsis zoo raug tso cai thiab tsis siv cov cuab yeej ntsuas kev puas tsuaj; Thaum muaj qhov tsis xws luag txuas ntxiv ntawm cov welds, tsis muaj kev kuaj xyuas qhov tsis zoo; Thaum muaj cov kab nrib pleb tas mus li ntawm cov welds, tsis muaj kev kuaj xyuas qhov tsis zoo raug tso cai; Thaum muaj cov kab nrib pleb tas li ntawm cov welds Tsis muaj qhov tsis txaus ntseeg kev tshuaj xyuas raug tso cai. Thaum muaj teeb meem loj tshwm sim, vuam yuav tsum tau nres tam sim ntawd thiab kho vuam yuav tsum tau ua.
