Lub hom phiaj tseem ceeb: tshem tawm cov nplai thiab xeb ntawm qhov loj thiab nruab nrab qhov loj me forgings lossis hlau, thiab lwm yam. 1 tuj steel pob nrog txoj kab uas hla ntawm 1. 7700 kg ib cubic meter (feem ntau hu ua square), yog li nws lub ntim yog roughly 1000/7700 yog hais txog 1.3 square.
Lub pob steel nta: nruab nrab hardness, muaj zog toughness, cuam tshuam tsis kam, tuaj yeem siv tau ntau zaus, lub neej ntev, zoo resilience, muaj zog adhesion, ceev ceev ceev, tsawg xuab zeb noj, tsis tawg, siab brightness ntawm tu workpiece, zoo technical effect. , Kev huv ntawm cov hlau qhov chaw kho los ntawm cov khoom no tuaj yeem ncav cuag cov qauv thoob ntiaj teb. Qhov saum npoo roughness ncav cuag 25--100um, uas ua rau kom muaj kev sib cuag ntawm cov hlau nto, txhim kho qhov adhesion ntawm cov smear, thiab muaj txiaj ntsig zoo heev rau kev kho cov hlau nto thiab ntxiv dag zog rau cov qauv hlau. Nws yog qhov zoo tshaj plaws thiab qib siab tshaj plaws hauv tsev thiab txawv teb chaws. Zoo tagnrho rau kev ntxuav blasting, descaling thiab ntxiv dag zog rau cov khoom zoo.
