Tuag casting pwm yog cov pwm siv los cam khwb cia hlau rau hauv cov duab hauv siab. Vim hais tias cov pwm yog nyob rau hauv kev sib cuag nrog lub siab - kub molten hlau, cov kev ua hauj lwm yog hnyav heev. Nws yog rov raug rau cov hlau incandescent, thiab nws qhov kub thiab txias yog siab tshaj qhov kub forging pwm, ua rau thermal qaug zog tawg ntawm pwm nto.
Feem ntau, cov kev xav tau rau cov hlau siv hauv kev tuag casting pwm yog raws li hauv qab no:
① Tuag casting pwm steel yuav tsum muaj lub zog siab thiab muaj qee qhov kev sib tw, muaj zog txaus, thiab hnav tsis kam ntawm qhov kub thiab txias;
② Nws yuav tsum muaj cov thermal qaug zog zoo heev los tiv thaiv kev tawg thaum ntxov ntawm cov pwm;
③ Nws yuav tsum muaj cov thermal conductivity zoo, corrosion kuj, thiab oxidation kuj.
Nyob ntawm daim ntawv thov ntawm cov pwm tuag casting, nws yuav tsum muaj qhov sib txawv hardness qib. Lub hardness siab dua ua rau muaj kev hnav zoo dua thiab tiv thaiv cov hlau molten los ntawm adhering rau pwm kab noj hniav. Cov tub ntxhais mos mos thiab lub siab -hardness nto muab cov pwm tuag casting ua haujlwm zoo heev.
Cov qib steel hauv tsev siv rau tuag-casting aluminium alloys suav nrog 3Cr2W8V, 3Cr3Mo3W2V, thiab 4Cr5MoSiV, nrog hardness qhov tseem ceeb ntawm 42-50 HRC.
Cov qib steel hauv tsev rau tuag-casting tooj liab alloys suav nrog 3Cr2W8V, 3Cr3Mo3V, thiab 3Cr3Mo3Co3V, nrog hardness qhov tseem ceeb ntawm 42-48 HRC.
Cov qib steel hauv tsev rau tuag-casting zinc alloys suav nrog 40CrMo, 3Cr2W8V, CrWMn, thiab 4Cr5MoSiV, nrog hardness qhov tseem ceeb ntawm 42-48 HRC.
Qhov zoo dua feem ntau siv tuag-casting pwm steels suav nrog: H13, 8407, 8418, 1.2344, thiab 1.1343. Nws yog ib qho tseem ceeb kom tau txais cov pwm steels los ntawm cov neeg muag khoom ntseeg siab thiab muaj koob npe.
