1. Txij li thaum lub shrinkage ntawmstainless hlau yeeb nkab castings zoo heev tshaj qhov shrinkage ntawm cam khwb cia hlau, thiaj li yuav tiv thaiv shrinkage thiab shrinkage defects ntawm castings, feem ntau ntawm cov kev ntsuas siv nyob rau hauv lub casting txheej txheem yog risers, txias hlau thiab nyiaj pab kom ua tau zoo nruam solidification.

2. Txhawm rau tiv thaiv kom tsis txhob shrinkage, shrinkage, porosity thiab tawg tsis xws luag ntawm stainless hlau raj, lub phab ntsa thickness yuav tsum yog uniform, tsis txhob ntse thiab txoj cai-angle qauv, ntxiv ntoo chips rau molding xuab zeb, ntxiv coke rau cov tub ntxhais, thiab siv hollow core thiab roj sandstone los txhim kho qhov kev pom zoo thiab ua pa-muaj peev xwm ntawm cov xuab zeb lossis cov tub ntxhais.

3. Vim tias qhov dej tsis zoo ntawm cov hlau molten, txhawm rau tiv thaiv kev sib cais txias thiab tsis txaus, cov phab ntsa thickness ntawm cov casting yuav tsum tsis pub tsawg tshaj 8 hli;qhuav casting los yog kub casting yuav tsum ua kom qhov kub thiab txias, feem ntau 1520 ~ 1600℃.Vim tias qhov ntsuas kub ntawm qhov ntsuas kub siab, qhov ntsuas kub ntawm super-kub siab yog siab, lub sijhawm khaws cov kua dej yog qhov ntev, thiab cov kua dej tuaj yeem txhim kho.Txawm li cas los xij, yog tias qhov kub thiab txias dhau lawm, nws yuav ua rau muaj qhov tsis xws luag xws li coarse nplej, kub tawg, pores thiab xuab zeb nplaum.
