Seamless steel kav yuav tsum ua kev ntsuas kev ua tau zoo. Seamless steel kav yog siv dav hauv kev tsim cov qauv thiab cov khoom siv kho tshuab, xws li roj av drilling rods, automotive shafts, tsheb kauj vab thav duab, thiab steel scaffolds siv hauv kev tsim kho. Cov ntaub ntawv thiab cov sijhawm ua haujlwm tau dav ua los ntawm cov kav dej steel. Mechanical performance testing method (METHOD) feem ntau yog muab faib ua ob hom, ib qho yog stretching test, thiab lwm yam yog Hardness test.
Kev ntsuas tensile yog tswj seamless steel rau hauv cov qauv. Rub tus qauv mus rau qhov tawg ntawm lub tshuab ntsuas stretch, thiab tom qab ntawd txiav txim siab ib lossis ob peb yam khoom siv. Feem ntau, tsuas yog lub zog tensile, lub zog yield, lub elongation ntawm post-disconnection, thiab lub elongation ntawm stretch npaum li cas ntawm qhov txo nyob rau hauv cheeb tsam. 20G high-pressure boiler raj yog siv nyob rau hauv lub boiler tivthaiv Cheebtsam, uas yog feem ntau yog siv nyob rau hauv boiler daim ntaub ntawv hauv qab no 39 kg. Nyob rau hauv thiaj li yuav siv nws nyob rau hauv siab dua, lub cua sov nto raj yog feem ntau tsim heev tuab.
Txhawm rau txo cov thermal tsis kam thiab txuag cov hlau, kom ntseeg tau tias muaj kev ruaj ntseg ntawm lub siab lossis siab-siab boiler steel, thiab tib lub sijhawm kom txo cov hlau, 16mng feem ntau yog siv. Tib lub sijhawm, muaj cov hlau tshwj xeeb uas ntxiv cov hlau thiab cov khoom tsis yog hlau xws li lub ntiaj teb tsis tshua muaj, magnesium, thiab cov khoom tsis yog hlau. Qhov no yuav txhim kho kev ua haujlwm ntawm boiler steel, txo kev noj cov hlau, thiab txo cov thermal kuj. Qhov kev sim ncab yog qhov yooj yim tshaj plaws kev ntsuas kev ua tau zoo (METHOD). Yuav luag tag nrho cov ntaub ntawv hlau yuav tsum tau hais txog qhov kev sim ncab ntev npaum li lawv muaj cov kev xav tau rau kev ua haujlwm zoo. Tshwj xeeb tshaj yog cov ntaub ntawv uas tsis yooj yim rau kev sim hardness, stretch tests tau dhau los ua ib qho kev ntsuas kev ua tau zoo xwb.
Qhov kev ntsuam xyuas hardness yog maj mam nias lub taub hau nyuaj rau hauv qhov chaw ntawm cov qauv raws li cov txheej txheem, thiab tom qab ntawd sim qhov tob lossis qhov loj ntawm qhov indentation los txiav txim qhov loj ntawm cov khoom hardness. Kev xeem Hardness yog qhov yooj yim tshaj plaws, ceev tshaj plaws, thiab yooj yim tshaj plaws los siv cov khoom siv ntsuas kev ua tau zoo. Lub hardness test tsis yog-destructive, thiab muaj ib tug zoo xws li hloov dua siab tshiab kev sib raug zoo ntawm hardness tus nqi ntawm cov khoom thiab lub tensile lub zog. Lub hardness ntawm cov khoom tuaj yeem hloov mus rau hauv tus nqi tensile lub zog, uas yog qhov tseem ceeb tshaj plaws.
Vim tias qhov ntsuas tensile tsis yooj yim rau kev sim, thiab nws yooj yim los hloov los ntawm hardness mus rau qhov siv, tib neeg muaj ntau dua thiab ntau dua kev sim tsuas yog sim cov hardness ntawm cov ntaub ntawv thiab tsawg dua sim lawv lub zog. Lub seamless steel yeeb nkab muaj qhov loj-sijhawm ntu, uas yog siv los ua lub raj xa dej, xws li cov kav dej ntawm cov roj, cov nkev, roj, dej, thiab qee yam khoom siv. Piv nrog cov khoom siv hlau xws li cov kav hlau thiab cov hlau puag ncig, thaum lub zog los tiv thaiv kev sib tw thiab kev sib tw yog tib yam, qhov hnyav yog lub teeb, uas yog ib qho kev lag luam steel.
Tshwj xeeb tshaj yog vim qhov kev vam meej tas mus li thiab kev tsim kho tshiab ntawm hardness meter manufacturing technology, qee cov ntaub ntawv uas tsis tuaj yeem kuaj qhov nyuaj, xws li seamless steel kav, stainless hlau (stainless acid-resistant steel) boards, thiab stainless hlau siv, thiab lwm yam, yog tam sim no. ua tau mus kuaj hardness ncaj qha. Yog li ntawd, ib qho kev sim hardness maj mam hloov cov qauv ntawm stretching xeem.
