Kub forgingyog forging ntawm hlau saum toj no qhov kub ntawm recrystallization.
Ua kom qhov kub thiab txias tuaj yeem txhim kho cov yas ntawm cov hlau, yog qhov tsim nyog rau kev txhim kho sab hauv zoo ntawm cov khoom ua haujlwm, kom nws tsis yooj yim rau tawg. Kev kub kub kuj tseem tuaj yeem txo cov hlau deformation tsis kam, txo qhov yuav tsum tau tonnage ntawm forging machinery. Tab sis kub forging txheej txheem, workpiece raug tsis zoo, nto tsis du, forging yooj yim los tsim oxidation, decarburization thiab hlawv poob. Thaum lub workpiece loj thiab tuab, cov khoom siv zog yog siab thiab plasticity tsawg (xws li dov ntawm cov phaj tuab ntxiv, qhov ntev ntawm cov pa roj carbon steel, thiab lwm yam),kub forgingyog siv. Thaum cov hlau (xws li txhuas, tin, zinc, tooj liab, txhuas, thiab lwm yam) muaj cov yas txaus thiab cov deformation tsis loj (xws li feem ntau stamping ua), lossis tag nrho cov nyiaj deformation thiab cov txheej txheem forging siv ( xws li extrusion, radial forging, thiab lwm yam) yog qhov zoo rau cov yas deformation ntawm cov hlau, feem ntau tsis siv kub forging, tab sis siv txias forging. Qhov ntsuas kub ntawm qhov pib forging kub thiab qhovzaum kawg forgingQhov kub ntawm qhov kub forging yuav tsum loj npaum li qhov ua tau kom ua tiav kev ua haujlwm forging ntau npaum li qhov ua tau los ntawm ib qho cua sov. Txawm li cas los, siabpib forgingqhov kub thiab txias yuav ua rau kev loj hlob ntawm cov hlau nplej ntau dhau thiab tsim cov cua sov, uas yuav txo qhov zoo ntawm forging qhov chaw. Thaum qhov kub thiab txias nyob ze rau qhov chaw melting ntawm cov hlau, cov khoom siv melting tsawg melting thiab intergranular oxidation yuav tshwm sim, uas ua rau overburning. Hla-burned billets feem ntau tawg thaum forging. Tus generalkub forgingkub yog: carbon steel 800 ~ 1250 ℃; Alloy structural steel 850 ~ 1150 ℃; Kev kub ceev steel 900 ~ 1100 ℃; Feem ntau siv aluminium alloy 380 ~ 500 ℃; Titanium alloy 850 ~ 1000 ℃; Brass 700 ~ 900 ℃.

Txias forgingyog qis dua cov hlau recrystallization kub ntawm forging, feem ntau hu ua txias forging ntawm chav tsev kub, thiab yuav siab tshaj li chav tsev kub, tab sis tsis ntau tshaj qhov recrystallization kub ntawm forging yog hu ua sov forging. Lub precision ntawm sov forging yog siab dua, qhov saum npoo yog du thiab deformation kuj tsis loj.
Lub workpiece tsim los ntawm txias forging nyob rau hauv ib txwm kub muaj siab precision nyob rau hauv cov duab thiab loj, du nto, ob peb txheej txheem thiab yooj yim rau automate ntau lawm. Ntau qhov chaw txias-forged thiab txias-nias tuaj yeem siv ncaj qha los ua cov khoom lossis cov khoom tsis tas yuav txiav. Tab sis nyob rau hauvtxias forging, vim tsis muaj plasticity ntawm cov hlau, nws yog ib qho yooj yim rau tawg thaum lub sij hawm deformation, thiab deformation kuj loj, yog liloj tonnage forgingthiab nias machinery yog xav tau.
