Kev cuam tshuam ntawm cov cua sov kub thiab lub sijhawm rwb thaiv tsev ntawm cov txheej txheem forging ntawm steel ingots. Thaum tshav kub kub thiab rwb thaiv tsev lub sij hawm yog ob lub ntsiab tsis nyob rau hauv lub forging txheej txheem ntawm steel ingots, uas ncaj qha cuam tshuam rau lub plasticity ntawm cov dawb paug thiab qhov zoo ntawm cov khoom kawg. Thaum xaiv cov cua sov kom tsim nyog, nws yog ib qho tsim nyog yuav tsum xav txog cov tshuaj muaj pes tsawg leeg ntawm cov hlau thiab cov kev cai ntawm cov txheej txheem forging.
Ua ntej, cia peb nkag siab tob dua ntawm cov txiaj ntsig ntawm cov cua sov kub ntawm steel ingots. Cov cua kub ntau dhau yuav ua rau cov nplej hauv cov hlau ingot loj hlob sai heev, yog li txo cov plasticity ntawm cov khoom. Ntawm qhov tod tes, yog tias qhov cua sov kub tsawg dhau, nws yuav ua rau cov cua sov tsis txaus, ua rau qhov kub tsis sib xws ntawm cov hlau ingot thiab yog li cuam tshuam rau qhov zoo ntawm forgings. Yog li ntawd, xaiv cov cua kub kom tsim nyog yog qhov tseem ceeb los xyuas kom meej tias cov hlau ingot mus txog qhov yuav tsum tau muaj plasticity.
Raws li phau ntawv forging, qhov cua kub rau forging steel ingots feem ntau yuav tsum nyob nruab nrab ntawm 1150 thiab 1270 ℃. Txawm li cas los xij, rau cov xwm txheej uas qhov sib piv ntawm forging tsawg dua 1.5, cov kev hloov kho yuav tsum tau ua. Piv txwv li, rau cov qib hlau zoo tib yam, qhov pom zoo cua sov yog 1050 ℃ thaum qhov sib piv forging yog 1.5-1.3. Yog tias qhov sib piv forging tsawg dua 1.3 lossis tsis muaj forging piv hauv zos, nws raug nquahu kom txo cov cua sov kom txog 950 ℃.
Ntxiv nrog rau qhov kub thiab txias, lub sij hawm rwb thaiv tsev kuj yog ib qho tseem ceeb ntawm kev txiav txim siab ntawm plasticity thiab kub uniformity ntawm steel ingots. Qhov ntev ntawm lub sij hawm rwb thaiv tsev cuam tshuam ncaj qha rau seb qhov nruab nrab ntawm cov hlau ingot tuaj yeem ncav cuag qhov kub thiab txias thiab xyuas kom meej qhov sib xws ntawm qhov kub thiab txias hauv ntau qhov chaw. Lub sij hawm rwb thaiv tsev ntev dua tuaj yeem ua kom zoo sib xws ntawm qhov kub thiab txias ntawm cov hlau ingot, yog li txhim kho cov yas ntawm lub ingot thiab txo cov deformation thiab tsis xws luag ntawm forging. Yog li ntawd, thaum tsim cov txheej txheem forging, nws yog ib qho tsim nyog yuav tsum txiav txim siab lub sij hawm rwb thaiv tsev kom tau raws li cov kev cai forging thiab cov qauv zoo.
Hauv cov ntsiab lus, cua sov thiab tuav lub sijhawm yog qhov tseem ceeb heev hauv cov txheej txheem forging ntawm steel ingots. Los ntawm kev xaiv cov cua sov kom tsim nyog thiab lub sijhawm rwb thaiv tsev tsim nyog, nws tuaj yeem ua kom cov hlau ingot tau txais cov yas uas yuav tsum tau ua thiab xyuas kom muaj qhov sib txawv ntawm qhov kub thiab txias. Yog li ntawd, rau cov hlau ingots loj, nws yog qhov zoo tshaj plaws los ua kom kub ingot them tom qab demolding kom tsis txhob muaj kev nthuav dav ntawm cov khoom siv sab hauv thiab qhov kev pheej hmoo ntawm ingot tawg los ntawm thermal thiab cov qauv kev ntxhov siab tsim tawm thaum txias rau chav sov.
