Kauv Pipe (SSAW)Hoobkas txuas tseem ceeb heev rau qhov poob ntawm kauv yeeb nkab. Los ntawm cov hlau phaj mus rau cov khoom tiav cov nqi ntawm cov kauv yeeb nkab, qhov poob tus nqi ntawm cov kauv yeeb nkab chaw tsim tshuaj paus thaum welding ncaj qha cuam tshuam tus nqi ntawm cov kauv yeeb nkab.

Cov mis rau xam qhov tawm los ntawm kauv yeeb nkab:
b = Q/G*100

b yog cov khoom tiav, %; Q yog qhov hnyav ntawm cov khoom tsim nyog, hauv tons; G yog qhov hnyav ntawm cov ntaub ntawv raw hauv tons.

Yield muaj kev sib raug zoo nrog kev siv hlau coefficient K.

b=(GW)/G*100=1/K

Lub ntsiab tseem ceeb cuam tshuam rau cov khoom tsim tau yog ntau yam hlau poob thaum lub sij hawm tsim khoom. Yog li ntawd, txoj kev los txhim kho cov khoom tsim tau yog tsuas yog los txo ntau yam hlau poob.

Txij li cov khoom siv raw siv nyob rau hauv txhua lub rooj cob qhia steel dov yog txawv ntawm cov khoom siv dov, piv txwv li, qee qhov steel dov rhiav siv steel ingots li raw cov ntaub ntawv, qhib blanks nyob rau hauv nruab nrab, thiab yob rau hauv cov ntaub ntawv; qee qhov kev cob qhia ncaj qha siv steel ingots ua raw khoom thiab yob rau hauv cov ntaub ntawv; steel billets yog siv los ua raw khoom los yob rau hauv cov ntaub ntawv; kuj tseem muaj qee qhov kev cob qhia uas siv cov hlau ua raw khoom los ua ntau yam khoom tiav steel. Yog li ntawd, nws yog ib qhov nyuaj rau siv ib tug yield xam txoj kev los qhia thiab sib piv cov metallurgy qhov teeb meem nyob rau hauv cov txheej txheem ntau lawm, thiab nws kuj yog ib qho nyuaj rau xav txog qhov sib txawv ntawm cov txheej txheem ntau lawm thiab theem kev tswj ntawm lub rhiav. HSCO kauv yeeb nkab Hoobkas tau hais tias muaj ntau txoj hauv kev los xam cov txiaj ntsig, xws li cov txiaj ntsig ntawm steel ingots, yield ntawm steel ingots, thiab cov tawm los ntawm txawv teb chaws billets. Txhua lub khw dov yuav tsum raug xam raws li qhov xwm txheej tshwj xeeb.

Kauv yeeb nkab poob tus nqi xam:

Kauv yeeb nkab raug poob tus nqi yog hais txog qhov pov tseg piv ntawm cov khoom siv raw hauv cov txheej txheem tsim cov kav raj. Raws li kev txheeb cais ntawm cov kws tshaj lij thiab cov neeg ua haujlwm ua haujlwm tau ntau xyoo, qhov poob qis ntawm kev tsim cov kav raj yog nruab nrab ntawm 2% thiab 3%.
nruab nrab. Nyob rau hauv cov txheej txheem tsim cov kauv raj, cov khoom tseem ceeb ntawm cov khoom pov tseg yog: lub hauv ntej ntawm cov kauv raj tsim, tus Tsov tus tw, milling ntug ntawm cov khoom siv raw, thiab cov kauj ruam tsim nyog hauv cov txheej txheem kauv raj. Yog tias cov kav hlau tsis tuaj yeem milled thiab tailed raws li cov qauv ib txwm muaj thaum lub sijhawm tsim khoom, cov yeeb nkab steel uas tsim muaj tus nqi qis heev.

Yuav ua li cas tswj qhov poob tus nqi ntawm cov kauv yeeb nkab?
1. Tom qab cov kauv steel yeeb nkab tsim, nws yog ib qho tsim nyog yuav tsum tau txiav thawj daim thiab tshem tawm tus Tsov tus tw kom tsis txhob muaj qhov tsis sib xws ntawm cov yeeb nkab steel. Qhov no yog ib qho tseem ceeb ntawm cov txheej txheem los xyuas kom meej cov specification thiab cov tsos ntawm cov yeeb nkab steel, thiab pov tseg yuav raug generated thaum lub sij hawm txoj kev no.

2. Rau kev ua cov khoom siv raw, cov sawb hlau yuav tsum tau milled thiab lwm yam kev kho mob ua ntej vuam. Hauv cov txheej txheem no, cov ntaub ntawv pov tseg kuj yuav raug tsim tawm.
