Hauv kev lag luam khoom siv hauv tsev, kev txhim kho ntawm ntau cov kav dej sib txawv. Vim lawv cov yam ntxwv sib txawv, kuj tseem muaj qee qhov kev ncua deb ntawm cov kav dej. Square yeeb nkab yog ib qho ntawm ntau cov kav dej hauv cov khoom siv hauv tsev. Nws yog tsim los ntawm sawb hlau tom qab ua tiav. Cov yam ntxwv ntau yam ntawm cov kav hlau yuav tsum tau nkag siab los ntawm txhua tus. Txawm li cas los xij, hauv kev lag luam khoom siv hauv tsev, kev txhim kho ntawm ntau cov kav dej sib txawv. Vim lawv cov yam ntxwv sib txawv, muaj qee qhov kev ncua deb ntawm cov kav dej. Square yeeb nkab yog ib qho ntawm ntau cov kav dej hauv cov khoom siv hauv tsev. Nws yog tsim los ntawm kev ua sawb hlau. Ntau yam ntawm cov yeeb nkab steel yuav tsum tau nkag siab los ntawm txhua tus neeg, tab sis tom qab tag nrho, vim muaj kev sib raug zoo ntawm cov kav hlau steel thiab lwm yam khoom siv raw, cov xwm txheej tshwj xeeb yog xav tau rau kev khaws cov kav hlau.
Thaum khaws cov kav dej seamless steel, peb yuav tsum xub xaiv qhov chaw tsim nyog. Peb yuav tsum xav txog ntau yam sab nraud, corrosiveness ntawm cov kav hlau, thiab lwm yam, yog li qhov chaw yuav tsum huv, qhuav thiab cua, thiab qhov chaw muaj teeb meem gases. Seamless steel kav yog Weeds thiab lwm yam khib nyiab yuav tsum tau muab tshem tawm nyob rau hauv lub sij hawm, thiab sab nrauv ntawm cov hlau yuav tsum tau ceev kom huv si. Yog tias muaj cov kua qaub, alkalis, ntsev, thiab lwm yam hauv lub tsev khaws khoom, nws yuav yooj yim ua rau cov yeeb nkab steel thiab ua rau corrosion ntawm cov yeeb nkab steel, yog li sim txiav nws thiab tsis txhob cia nws kov. Tsis tas li ntawd, rau cov khoom siv hlau nrog cov nqi siab dua, koj tuaj yeem txiav txim siab muab tso rau hauv lub tsev rau khoom kom zoo cia. Nyob ntawm thaj chaw thaj chaw, muaj cov tsev khaws khoom kaw uas muaj qhov cua zoo.
