Lub neej ntawmkauv steel yeeb nkabmuaj kev sib raug zoo nrog decarburization, yog tias decarburize nto, lub zog nto thiab hnav tsis kam yuav txo qhov cuam tshuam ncaj qha rau lub neej ntawm kev siv txhua hnub.Hauv cov txheej txheem kev kho cua sov, nws yuav tsum tau sim kom tsis txhob cia cov phab ntsa sab hauv thiab sab nrauv thiab raug huab cua.Qhov tshwm sim nruab nrab kauv hlau nto decarburization yog cov pa oxygen, dej vapor thiab cov pa oxidizing xws li carbon dioxide, thaum lub qhov chaw ntawm lub kauj thiab cov roj cua kub sib cuag lub kauj yuav ua rau oxidation thiab decarburization, yog li ntawd, kev tswj cov pa roj carbon dioxide nyob rau hauv lub coil. qhov cub thiab qhov kev faib ua feem ntawm carbon monoxide yog qhov tseem ceeb heev.Nyob rau hauv qhov tseeb, cov kauv hlau forging rauv tiv thaiv cua ntawm nitrogen ntxiv yog zoo heev, ib co ntawm cov nitrogen oxide roj yuav dispersed kom txo tau cov kauv steel decarburization.

Txhawm rau txuas ntxiv lub neej ntawm kauv steel yeeb nkab, yog li cov kev taw qhia tseem ceeb ntawm kauv welded yeeb nkab yog:

(1) kev tsim cov kab loj loj tuab-walled raj txhawm rau txhawm rau txhim kho lub peev xwm tiv thaiv kom muaj peev xwm nce siab feem ntau muab kauv welded yeeb nkab;

(2) kev tsim kho tshiab ntawm cov hlau, smelting tshuab los txhim kho qib ntawm kev tsim khoom thiab zoo zoo welded yeeb nkab vuam, dav siv los tswj dov thiab dov tom qab cov txheej txheem kev kho cua sov, txhawm rau txhawm rau txhim kho qhov toughness thiab weldability. lub cev lub cev;

(3) txhawm rau tsim cov kav dej coated, xws li cov phab ntsa sab hauv ntawm lub raj coated nrog cov txheej txheem tiv thaiv corrosion, tsis tsuas yog txuas lub neej thiab txhim kho qhov smoothness ntawm sab hauv phab ntsa, txo cov kua dej sib txhuam, txo qhov ntim ntawm cov quav thiab av, txo qhov tus naj npawb pigging, txo tus nqi kho.

(4) kev tsim thiab tsim cov qauv hlau tshiab, xws li ob chav kauv welded yeeb nkab, uas yog ib nrab ntawm lub thickness ntawm phab ntsa rau hauv ob chav welded steel yeeb nkab, tsis tsuas yog qhov kev siv zog yog siab dua tib lub thickness ntawm tib lub raj, thiab yuav tsis tshwm sim brittle tsis ua hauj lwm.Thaum siv cov kauv welded yeeb nkab ua raws qee cov qauv rau kev tsim khoom thiab kev siv tshuab, kev tswj xyuas nruj ntawm cov txheej txheem ntau lawm, nws muaj qhov zoo thiab kev ua tau zoo, ua lub luag haujlwm tseem ceeb hauv kev siv thiab kev txhawb nqa.Txoj kev loj hlob ntawm qhov chaw muab kauv welded yeeb nkab yog loj, kev loj hlob ntawm txawv industries thiab teb thiab nce qib, zoo txo ​​cov hassle ntawm kev tsim kho thiab lub tsev, kom paub lawv tus nqi tag nrho.
