Kuthiwani ngokusebenza kokuqina kwangaphakathi kokushisa okuphakathi
Kuthiwani ngokusebenza kwe ukuqina kwangaphakathi kokushisa kokuqina kokuqina?
1.Ukuqina kobuso: Ubulukhuni bendawo yokusebenza obucinywa ebusweni ngokushisa okuphezulu nokuphakathi kokuvama kokushisa kuvame amayunithi ama-2 kuye kwayi-3 (HRC) aphakeme kunokucima okujwayelekile.
2.Gqoka ukumelana: Ukumelana kokugqoka kokwenziwa komsebenzi ngemuva kokucishwa kwemvamisa ephezulu kuphakeme kunokucima okujwayelekile. Lokhu kungenxa yenhlanganisela yezinhlamvu ezincane ze-martensite kusendlalelo esiqinile, ukusabalalisa okuphezulu kwe-carbide, ukuqina okuphezulu, kanye nengcindezi ephezulu yokucindezela komhlaba.
3.Ukukhathala amandla: ukucisha okuphezulu naphakathi nendawo ukuvala indawo kuthuthukisa kakhulu ukukhathala futhi kunciphise ukuzwela kwe-notch. Okwenziwe komsebenzi wento efanayo, ukujula kwesendlalelo esiqinisiwe kungaphakathi kwebanga elithile. Njengoba ukujula kwesendlalelo esiqinisiwe kukhuphuka, amandla okukhathala ayanda, kepha lapho ukujula kwesendlalelo esiqinisiwe kujule kakhulu, ungqimba olungaphezulu luyacindezela, ngakho-ke amandla okukhathala ayancipha lapho ukujula kwesendlalelo esiqinisiwe kukhula. Ukukhuphuka okukhulu. Ngokuvamile, ukujula kwesendlalelo esiqinile ngu- δ = (10 ~ 20)% D. Kufaneleke ngokwengeziwe, lapho D. Ingabe ububanzi obusebenzayo bento yokusebenza
