Ukubuka Konke kweBearing Steel

Insimbi yokuthwala isetshenziselwa ukwenza amabhola, ama-roller kanye namasongo okuthwala. Insimbi yokuthwala inobulukhuni obuphezulu nobufanayo, ukumelana nokuguguleka kanye nomkhawulo ophezulu wokunwebeka. Izidingo zokufana kokwakheka kwamakhemikhali, okuqukethwe kanye nokusatshalaliswa kwezinto ezingezona ezensimbi, kanye nokusatshalaliswa kwama-carbide ensimbi yokuthwala ziqinile kakhulu. Ingenye yezinhlobo zensimbi eziqinile kakhulu kuyo yonke insimbi ekhiqizwayo.

Amazinga ensimbi ezinsimbi ezithwala izinsimbi ezivamile uchungechunge lwensimbi ethwala i-chromium ephezulu, njenge-GCr15, i-Gcr15SiMn, njll. Ngaphezu kwalokho, izinsimbi ezithwala izinsimbi ezithwala izinsimbi, njenge-20CrNi2Mo, i-20Cr2Ni4, njll., zingasetshenziswa futhi ngokwezimo zokusebenza ezahlukene, izinsimbi ezithwala insimbi engagqwali, njenge-9Cr18, njll., kanye nezinsimbi ezithwala ukushisa okuphezulu, njenge-Cr4Mo4V, i-Cr15Mo4V2, njll.

Impahla engokoqobo

Izakhiwo ezibonakalayo zensimbi ethwalayo zifaka phakathi isakhiwo esincane, ungqimba olukhishwe i-carburing, ukufakwa okungeyona insimbi kanye nesakhiwo esikhulu. Ngokuvamile, imikhiqizo ilethwa nge-hot rolling annealing kanye ne-cold drawing annealing. Isimo sokulethwa kufanele siboniswe enkontilekeni. Isakhiwo esikhulu sensimbi kumele singabi na-shrinkage cavity, i-subcutaneous bubble, i-white spot kanye ne-micro pore. I-central porosity kanye ne-general porosity akufanele kudlule ibanga 1.5, futhi ukuhlukaniswa akufanele kudlule ibanga 2. Isakhiwo sensimbi esifakwe i-arneal kumele sisatshalaliswe ngokulinganayo i-fine-grained pearlite. Ukujula kwesendlalelo se-decarburing, ukufakwa okungeyona insimbi kanye nokungalingani kwe-carbide kufanele kuhambisane nezindinganiso zikazwelonke ezifanele.
