Lub caij nplooj ntoos hlav steel yog hais txog cov hlau tshwj xeeb uas siv hauv kev tsim cov springs thiab elastic ntsiab vim nws elasticity nyob rau hauv quenching thiab tempering tej yam kev mob. Lub elasticity ntawm cov hlau yog nyob ntawm nws lub peev xwm deform, uas yog, nyob rau hauv ib qho kev teev tseg, kom dais ib yam khoom uas tsis tas yuav deformation tom qab lub load raug tshem tawm.
Lub caij nplooj ntoos hlav steel yuav tsum muaj cov khoom siv hlau zoo heev (siab purity thiab uniformity), zoo deg zoo (kev tswj nruj ntawm qhov tsis xws luag thiab decarbonization), cov duab thiab qhov loj.
Lub caij nplooj ntoos hlav steel tuaj yeem tsim los ntawm lub tshuab hluav taws xob, qhib lub qhov cub hluav taws xob lossis lub tshuab hluav taws xob oxygen; Lub caij nplooj ntoos hlav hlau zoo nrog cov khoom zoo lossis cov khoom tshwj xeeb yog ua kom zoo los ntawm electroslag rauv lossis lub tshuab nqus tsev. Cov ntsiab lus ntawm cov pa roj carbon, manganese, silicon thiab lwm cov ntsiab lus tseem ceeb hauv lub caij nplooj ntoos hlav steel yog nqaim, yog li cov tshuaj muaj pes tsawg leeg yuav tsum tau tswj nruj me ntsis thaum smelting. Thaum cov ntsiab lus silicon siab, nws yog ib qho yooj yim los tsim npuas thiab lwm yam tsis xws luag, thiab thaum cov hlau ingot tsis txias tom qab forging thiab dov, nws yog ib qho yooj yim los tsim cov pob dawb. Yog li ntawd, smelting raw cov ntaub ntawv yuav tsum qhuav, kom deb li deb tau tshem tawm cov pa roj thiab inclusions, thiab kom tsis txhob molten steel overheating.
Ua ntej peb tsim lub tsheb kauj vab thiab khiav tom qab ib lub sijhawm, tom qab lub caij nplooj ntoos hlav qaug zog compressing, ua rau tag nrho lub cav teeb, nws yog ib qho yooj yim los ua kom tawg ntawm lub tog raj kheej taub hau ntsia liaj qhov rooj, tam sim no peb muaj qhov no ntxiv dag zog rau tom qab, kom txo tau lub tog raj kheej taub hau. bolt tawg muaj txiaj ntsig zoo ntawm T, lwm qhov yog peb qhov pib bar, feem ntau muab tso rau nws, peb siv thiab lub Hoobkas, Peb siv 45 rau kev hloov kho, uas tuaj yeem xyuas kom meej tias nws yuav tsis ua kom tshem tawm thiab co ntawm cov zis ncej thiab pib pas nrig. ntawm lub cav nyob rau hauv lub nquag pib ntawm ntau zaus.
