Txawm hais tias qhov zoo ntawm qhov hluav taws kub, annealing, ignition, quenching, thiab lwm yam txheej txheem thermal kho, cov kav hlau yuav tsum tau ua cov txheej txheem yooj yim xws li cua sov, rwb thaiv tsev thiab cua txias, thiab lwm yam thaum lub sij hawm kho thermal. Nyob rau hauv cov txheej txheem no, cov kav hlau steel yuav ua rau muaj qhov tsis xws luag.Steel yeeb nkab thermal kho qhov tsis xws luag feem ntau suav nrog kev ua haujlwm tsis zoo xws li cov ntaub so ntswg tsis zoo, qhov loj me, qhov tawg, abrasions, hnyav oxidation, desertarbon, overheating lossis over-burning, thiab oxidation xws li steel yeeb nkab. nto oxidation thaum tiv thaiv kev kho cua sov.
Kev ua tau zoo ntawm cov yeeb nkab steel tsis tsim nyog: Thaum lub sij hawm kho cua sov, kev ua haujlwm ntawm cov yeeb nkab steel tsis yog hlau vim yog cov yam ntxwv xws li cov cua kub tsis raug ntawm cov yeeb nkab steel, lub sij hawm thermal rwb thaiv tsev tsis tsim nyog, thiab qhov txias txias ceev, lossis ib yam nkaus. qeeb txias ceev, los yog qeeb txias ceev los yog qeeb heev.
Hauv qhov no, thaum tsim cov txheej txheem cua sov, cov ntsiab lus alloy hauv cov hlau, cov cua kub ntawm cov yeeb nkab steel, cov ntaub so ntswg qub thiab qhov loj ntawm cov hlau auscolus hloov yuav tsum tau txiav txim siab tag nrho.Qhov thib ob yog los tsim cov cua kub ntawm steel yeeb nkab kev kho cua sov raws li cov hlau-carbon tshuav daim duab.Qhov thib peb yog kom paub meej txog cov txheej txheem thermal kho, cua sov kub, rov qab kub thiab txias ceev.Tom qab cov txheej txheem yog formulated, nws yuav tsum tau kuaj xyuas los ntawm cov khoom me me ua ntej lub zog tsim.
Qhov luaj li cas ntawm cov yeeb nkab steel tsis tsim nyog: Tom qab cua sov ntawm cov yeeb nkab steel, qhov loj yuav hloov pauv hauv qee qhov xwm txheej, suav nrog kev hloov pauv ntawm cov kab sab nraud, ellipse, thiab dabtsi yog khoov.Qhov kev hloov ntawm cov kab hlau sab nraud feem ntau tshwm sim hauv cov txheej txheem quenching. Tom qab cov yeeb nkab steel yog quenched, cov ntaub so ntswg loj ua martensite thiab bellnia. Vim yog cov kev hloov pauv ntawm cov ntaub so ntswg, qhov ntim hloov pauv ua rau cov txheej txheem sab nraud ntawm cov yeeb nkab steel.In thiaj li yuav txo tau cov kev hloov ntawm cov txheej txheem sab nraud, cov txheej txheem ntawm txoj kab uas hla yog feem ntau ntxiv tom qab cov txheej txheem ignition.Cov kev hloov ntawm lub ellipse feem ntau tshwm sim ntawm qhov kawg ntawm cov yeeb nkab steel, feem ntau tshwm sim los ntawm qhov loj -caliber nyias -walled steel kav thaum lub sij hawm ntev-lub sij hawm kub kub cua sov.Txhawm rau lub rationality ntawm lub cua sov system los tiv thaiv lub ntsiab kev hloov nyob rau hauv ellipse.Qee lub sij hawm, txawm tias cov cua sov system yog. tsim nyog, thaum tus nqi D/S loj dhau lawm, cov yeeb nkab steel yuav raug "hlawv", uas yuav ua rau qhov kawg "tsis hloov". Nyob rau hauv rooj plaub no, ntev li ntev raws li cov yeeb nkab steel siv tau los tig lub ntug ntawm cov yeeb nkab steel, nws tuaj yeem tiv thaiv nws los tiv thaiv cov yeeb nkab steel los tiv thaiv nws.
Muaj ntau yam cuam tshuam rau dabtsi yog khoov, feem ntau suav nrog steel yeeb nkab cua sov thiab tsis sib xws, tshwj xeeb tshaj yog cov cua txias ceev ntawm cov longitudinal lossis kab rov tav qhov chaw thaum cov yeeb nkab steel yog quenched. Feem ntau hais lus, nkhaus steel kav yuav raug tshem tawm los ntawm cov tshuab ncaj.
Steel tube nto tawg: Thaum lub sij hawm kho cua sov txheej txheem ntawm cov yeeb nkab steel, qhov kub thiab txias siab heev tuaj yeem ua rau cov yeeb nkab steel los tsim cov kab nrib pleb.Qhov laj thawj tseem ceeb yog los ntawm cov cua kub ceev los yog txias ceev.
Thaum lub alloy tuab phab ntsa steel yeeb nkab yog rhuab, yog hais tias qhov kub nyob rau hauv lub cub tawg yog siab dhau lawm, cov yeeb nkab steel yuav ntsib qhov kub thiab txias sai sai tom qab nkag mus rau hauv lub cub tawg.Thaum lub tensile lub zog ntawm cov khoom yog txwv, cov kab nrib pleb tshwm nyob rau saum npoo. ntawm cov yeeb nkab steel.
Vim cov txheej txheem quenching, qhov tshwm sim ntawm qhov tawg thaum lub sij hawm steel yeeb nkab kub theem quenching yog qhov siab.Thaum cov yeeb nkab steel muaj cov khoom tsis-hlau sib xyaw, cov khoom, thiab cov ntaub so ntswg bias, qhov ua tau ntawm quenching tawg hauv cov kav hlau steel nce. kom txo tau cov thermal kho cov kab nrib pleb ntawm cov yeeb nkab steel, ntawm ib sab, lub tshuab cua sov thiab cua txias ntawm cov yeeb nkab steel yuav tsum tau tsim raws li hom hlau, thiab qhov tsim nyog quenching nruab nrab yuav tsum raug xaiv; ntawm qhov tod tes, cov yeeb nkab harden uas tau quenched yuav tsum tau rov qab los yog annealing kom tshem tawm nws cov kev ntxhov siab sab hauv kom sai li sai tau.
Qhov chaw khawb thiab pob zeb raug mob ntawm cov yeeb nkab steel: feem ntau yog vim tias cov yeeb nkab steel yog rhuab los yog rhuab nyob rau hauv lub cua sov rauv, nyob rau hauv lub quenching ntaus ntawv los yog thaum lub sij hawm cov txheej txheem ntawm cov menyuam conveying txheej txheem, cov cuab yeej thiab workpieces uas tshwm sim nrog nws nyob rau hauv kev sib cuag nrog cov tsis xws luag tsim nyob rau hauv lub Nyob rau hauv thiaj li yuav tiv thaiv tau qhov tsis xws luag, thaum ua kom lub cev ua hauj lwm ntawm cov khoom cua sov, tus txheeb ze zawv zawg ceev ntawm steel kav thiab workpieces, cov cuab yeej thiab chais yuav tsum tau txo kom ntau li ntau tau kom txo tau lub sij hawm los tsoo nrog. ib leeg.
Nyob rau hauv luv luv, seb lub kub-rolled seamless steel yeeb nkab yog rhuab ua ntej cov yeeb nkab pores, los yog tom qab lub dov raj yog cua sov ua ntej kev txiav txim (txo) txoj kev, los yog nyob rau hauv nruab nrab ntawm lub txias-dov (rub) steel yeeb nkab, ntev npaum li cas. cov txheej txheem cua sov txheej txheem tsim thiab tsim thiab yog tias kev tswj tsis raug, lub raj (steel yeeb nkab) yuav tsim cov khoom tsis zoo xws li cua sov tsis sib xws, oxidation, decarburization, cua sov tawg, overheating, los yog hlawv ntau dhau, uas yuav cuam tshuam rau qhov zoo ntawm cov khoom. steel yeeb nkab.Yog li ntawd, kev tswj kom zoo ntawm cov kav dej (steel yeeb nkab) yuav tsum muaj zog.
