Stainless hlau muaj ntau dua precision casting cov khoom siv neeg kho tshuab dua li cam khwb cia hlau, tab sis nws cov kev ua tau cam khwb cia tsis zoo li cam khwb cia hlau. Vim tias lub siab melting taw tes ntawm stainless hlau Precision Casting, cov fluct steel yog tsis zoo, cov hlau yog nquag mus rau oxidation, thiab shrinkage yog loj. Lub linear shrinkage yog txog 1. {8-2. 5%, thiab Volumetric Shrinkage tus nqi yog hais txog {}}%. Txhawm rau tiv thaiv xws li txias kaw, tsis txaus pum, shrinkage porosity, cov kab nrib pleb
1) Cov qauv ntawm cov pouring system sib zog rau kev yooj yim, thiab cov ntoo khaub lig-seem yog qhov loj dua li cov hlau cam khwb cia, feem ntau siv ua kom qhuav lossis kub casting; Vim tias cov tsis zoo ntawm Molten hlau, txhawm rau tiv thaiv cov khaub thuas txias thiab tuab ntawm cam khwb cia steel seem tsis tuaj yeem tsawg dua 8 hli; Kev tsim nyog nce ntxiv cov ncuav twj ywm kub, raws li siab nchuav kub ua rau siab heev ntawm Molten hlau, thaum tswj nws lub xeev ua kua rau lub sijhawm ntev, uas tuaj yeem txhim kho nws lub ntsej muag. Txawm li cas los xij, ntau dhau lawm hliv qhov kub yuav ua rau tsis xws luag xws li kub tawg, coinal nplaum loj, xuab zeb adhesion, thiab porosity. Yog li ntawd, cov nchuav qhov kub ntawm cov ntoo loj thiab tuab thiab tuab tuab thiab muaj ntau txog 100 qib siab dua li lawv cov taw tes melting; Tus phab ntsa nyias, me me, thiab cov duab sib xyaw ua ke tau hliv ntawm qhov kub ntawm kwv yees li 150 degree saum toj no melting point ntawm cov hlau.
2) Vim tias Stainless hlau muaj ntau dua li cam khwb cia hlau nyob rau hauv precision porosting, nyob rau hauv thiaj li yuav tsum tau siv cov hlau casting, thiab cov nyiaj them rov qab yog siv hauv cov txheej txheem casting kom ua tiav cov txheej txheem.
Ib qho ntxiv, txhawm rau tiv thaiv shrinkage, tawg, thiab porosity sib xws, nws yog qhov tsim nyog los txhim kho cov prying cores, nws yog qhov tsim nyog rau kev sib tw thiab kev hloov pauv ntawm cov tub ntxhais lossis xuab zeb pwm.
