Cov txheej txheem kev nqis peev tuaj yeem txuag ntau lub tshuab ua haujlwm thiab kev siv lub sijhawm, thiab zoo heev txuag hlau raw cov ntaub ntawv. Nws cov yam ntxwv yog tias nws tuaj yeem nrum cov hlau ua hlau ntawm ntau cov alloys, tshwj xeeb tshaj yog cov khoom kub siab textile castings. Thaum nias pwm kev nqis peev, pwm tsim nrog qhov siab saum npoo yog siv, yog li saum npoo tiav ntawm lub peev pwm kuj tseem siab. Tsis tas li ntawd, lub plhaub pwm yog ua los ntawm cov txheej txheem refractory uas npaj los ntawm cov ntawv tshwj xeeb uas kub-siab kub tiv thaiv thiab cov khoom refractory, uas tau dai rau ntawm pwm lub peev txheej, thiab cov npoo ntawm cov kab noj hniav hauv kev sib cuag ncaj qha nrog molten hlau yog siab. Yog li ntawd, qhov ua tiav saum npoo ntawm kev nqis peev casting yog siab tshaj qhov ntawm qhov ua kev casting, Feem ntau, nws tuaj yeem ncav ra.1.6 ~ 3.2 μ M. qhov ntev ntawm qhov tseeb ntawm kev nqis peev yog qhov siab, feem ntau nws tuaj yeem ncav cuag ct4-6 (CT10 ~ 13 rau cov xuab zeb casting thiab CT5 ~ 7 rau kev tuag casting). Yog lawm, vim cov txheej txheem nyuaj ntawm kev nqis peev casting, muaj ntau yam cuam tshuam rau qhov loj me ntawm qhov tseeb ntawm kev nrum, xws li shrinkage ntawm cov khoom pwm, qhov deformation ntawm kev nqis peev pwm, txoj kab hloov ntawm pwm plhaub thaum lub sijhawm cua sov thiab cua txias. , Qhov ntsws me me ntawm cov alloy thiab qhov cuam tshuam ntawm cov casting nyob rau hauv cov txheej txheem solidification, yog li ntawd qhov ntau qhov tseeb ntawm qhov peev txheej peev yog siab dua, tab sis nws txoj kev sib xyaw tseem yuav tsum tau ua kom zoo dua qub (hauv kev siv, qhov ntev tsis sib xws ntawm lub siab kub ciab casting xav tau kev txhim kho ntau ntau).
