Amaphuzu Wokunakwa Ekusebenziseni Umshini Wokushisa Wokuvama Okuphezulu Kwe-Frequency we-Guide Rail Quenching

Lapho sisebenzisa i- umshini wokushisa wokungenisa ophezulu kanye nethuluzi lomshini wokucima ukucisha ojantshi besiqondisi, sidinga ukunaka amaphuzu alandelayo:

a. Ukukhethwa kwesivinini sokuhamba komshini Ngaphansi kwezimo ezithile zezinye izinqubo zenqubo, ijubane lihamba kancane, ujule lukhuni, kepha ukusebenza kahle kokukhiqiza kuncishisiwe. Uma isivinini sokuhamba sihamba kancane, ubunzima bendawo buzoncishiswa, ngakho-ke ijubane elihambayo kufanele lilawulwe ngaphakathi kobubanzi obungu-1.2 ～ 3mm / s.

b. Ukukhethwa kokushisa ukushisa kokushisa kuyisihluthulelo. Izinga lokushisa elifanele kakhulu lokucisha kufanele libe ngaphezu kwezinga lokushisa, kanye nendawo yokuncibilika kwe-phosphorus eutectic engaphansi kuka-957 ° C. Ngokuvamile, ibanga lokushisa elingu-900-950 ° C lifanelekile.

c. Ukucima okuphakathi: Ngenxa yobukhona benani elikhulu le-graphite ku-iron cast, izinga lokudlulisa ukushisa liyancipha, futhi ngasikhathi sinye, umphumela wezinto ze-Si ne-Mn element 1 unciphisa izinga elipholile lokupholisa. Ngakho-ke, ukucisha ukushisa okuphezulu okuvuthayo okuphezulu kwe-cast iron rails akudingi umthamo ophakeme kakhulu wokupholisa we-quenching medium. Ngokuvamile, amanzi kampompi afuthwa ukuze aphole, kanti ingcindezi yamanzi ingu-0.1 ～ 0.15MPa.
