Thaum twg kub hnyav, ib tus loj flange uas muaj teeb meem nyuab heev yuav raug ntaus vim yog lub cev deformation thiab deformation kuj. Yog li, yog tias koj xav ua tus flange uas muaj qhov siab ntawm qhov siab, koj tuaj yeem siv cov hluav taws kub ntau ntawm 900-1000 ° C. Lub hom phiaj ntawm kev sib flanges kub yog tsuas yog los txo qhov tsis kam ntawm cov hlau mus ua kom deformation, ua li cas thiaj li txo cov tonnage .
Lub khaub zeeg forging ntawm flange yog hloov me me nyob rau hauv cov flange loj ntawm qis kub forging. Forging nyob rau hauv 700 ° C los yog tsawg, qhov loj me me, peb muaj peev xwm soj ntsuam tias saum npoo tsis decarburized. Yog li, ntev li ntawm cov kev tsim nyog muaj kev tswjhwm, txias forging yog yooj yim mus nrhiav tau qhov zoo thiab qhov chaw tiav. Cold forging yog tus txheej txheem kev qis tshaj uas yog qis tshaj ntawm cov khoom ntawm recrystallization ntawm cov khoom thiab yog forged nyob rau hauv qab cua kub hauv qab tej qhov kub thiab txias. Cov ntaub ntawv cog lus muaj cov deformation loj hauv chav tsev kub thiab muaj peev xwm qee zaum hloov cov txheej txheem ntim txias.
