Cov kav dej yas yas hauv dej sab hauv thiab sab nraud muaj cov yam ntxwv hauv qab no:
Ua ntej, muaj cov txheej txheem yas rau ntawm qhov chaw sab hauv ntawm cov kav dej sab hauv thiab sab nraud, uas tuaj yeem tswj tau qhov zoo ntawm cov kav dej, txo cov dej tsis kam, thiab ua kom cov dej ntws. Tsis tas li ntawd, vim qhov ntim dej du, cov dej ntws tuaj yeem lav tau. Nyob rau tib lub sijhawm, yuav tsis muaj qhov ntsuas hauv lub raj xa dej thaum siv, tsis muaj kab mob yuav ua rau yug, thiab dej tsis zoo yuav raug txo.
Qhov thib ob, muaj cov txheej txheem yas rau sab nraud ntawm cov kav dej yas hauv thiab sab nraud, uas tuaj yeem ua rau kom muaj kev hloov pauv ntawm cov kav hlau yas. Cov txheej txheej ntawm txheej txheej ua rau muaj kev tiv thaiv corrosion ntawm cov yeeb nkab steel, muaj zog dej tsis kam, siab oxidation tsis kam, thiab muaj kev tiv thaiv zoo. Tsis tas li ntawd, qhov cuam tshuam ntawm ib puag ncig ntawm txheej txheej steel kav yuav raug txo kom tsawg. Vim hais tias thaum muab dej, cov kav dej yog inevitably faus rau hauv av, thiab kev nce hauv lub neej ntawm cov kav dej tuaj yeem txuas ntxiv tau zoo.
Xyuas seb cov txheej txheem ntawm cov kav dej yas yas:
Txoj kev tshuaj ntsuam xyuas tseem ceeb ntawm cov kav hlau yas muaj xws li kev tshuaj xyuas zoo li qub, kev tshuaj xyuas zoo li qub, kev kuaj pinhole, kev sim khoov, kev sim flattening, kev sim ntsuas kub tsawg, thiab lwm yam. Txhua txoj kev kuaj xyuas muaj nws cov ntsiab lus tseem ceeb.
Kev kuaj pom yog los xyuas qhov zoo ntawm cov yeeb nkab steel nrog qhov muag liab qab.
Kev ntsuas thickness yog ntsuas lub thickness ntawm cov txheej thickness ntawm plaub-point txheej ntawm lub voj voog ntawm ob kab rov tav.
Point-pin thwmsim hais txog kev siv cov hluav taws xob hluav taws xob hluav taws xob los kuaj xyuas qhov ntsuas hluav taws xob ntawm cov yeeb nkab steel hauv qhov ntsuas qhov ntsuas hluav taws xob, thiab tib lub sijhawm, nws yog qhov tsim nyog los xyuas seb lub txim hluav taws xob puas tsim los.
Kev sim khoov feem ntau yog khoov ntawm lub tshuab khoov lossis pwm. Nws yog ib nqi sau cia hais tias tsis muaj filling nyob rau hauv lub raj thaum lub sij hawm khoov xeem. Lub weld yog nyob rau sab ntawm lub ntsiab nkhaus.
Qhov kev sim flattelling yog muab qhov ntsuas qhov nruab nrab ntawm ob lub ntsiav tshuaj, thiab maj mam muab qhov sib nrug ntawm ob lub tiaj tiaj ntawm lub tshuab ntsuas siab mus rau plaub-tsib tsib feem ntawm qhov ntsuas qhov ntsuas. Qhov tseem ceeb
Kev sim ntsuas kub qis txhais tau hais tias qhov ntsuas qhov ntsuas tau muab tso rau hauv qhov ntsuas kub qis. Tom qab nyob rau ib teev, ces muab tso rau hauv qhov kub thiab txias ib puag ncig.
