Ukuba ngokwenene unolwazi olwaneleyo malungaimibhobho yepayipi, ungaqonda ngcono ukuba xa usebenzisa olu hlobo lombhobho, kukho iintlobo ezithile zokushisa. Ukuba unolwazi olungcono ngolu lwazi, oku kulandelayo kuya kuchaza ulwahlulo oluthile lokushisa kwimibhobho yombhobho:
1. Ubushushu obuphantsi
Ubushushu buqala kwi-150 ° ukuya kwi-250 °, ngenjongo yokugcina ubulukhuni obuphezulu kunye nokumelana nokuguguleka kwentsimbi ecinyiweyo, ukuze kuncitshiswe uxinzelelo lwangaphakathi kunye nokuqhekeka kokucima, kwaye kuthintelwe ukuqhekeka okanye ukonakala kwangaphambi kwexesha ngexesha lokusetyenziswa. Isetyenziswa kakhulu kwizixhobo ezahlukeneyo zokusika ezinekhabhoni ephezulu kunye nezixhobo zokulinganisa. Emva kokupholisa, ubulukhuni bulungile kakhulu.
2. Ubushushu obuphakathi
250 °~500 °, lo ngumzimba ogobileyo othambileyo, ojolise ekufumaneni amandla aphezulu okuvelisa, umda we-Elastic kunye nokuqina okuphezulu. Ngoko ke isetyenziswa ngokubanzi kunyango lwezinye ii-molds ezisebenzayo ezishushu, ukuze kufezekiswe iimfuno zobulukhuni ezihambelanayo.
3. Ukufudumala kobushushu obuphezulu
Ukusuka kwi-500 ° ukuya kwi-650 °, isakhiwo esifunyenweyo si-sorbite eqinisiweyo. Ngokwesiko, indibaniselwano yokucima kunye nokushisa okuphezulu isetyenziselwa unyango lobushushu, olubizwa ngokuba yi-quenching kunye ne-tempering treatment. Injongo kukufumana iipropati ezipheleleyo zoomatshini ezinamandla agqwesileyo, ubulukhuni, i-plasticity, kunye nokuqina. Kule nkalo, isetyenziswa kakhulu kwiimoto, kunye nezixhobo ezibalulekileyo zesakhiwo ezifana nezixhobo zoomatshini, ezifana neebholiti, iigiya, iishafti, njl. Ubulukhuni bayo bokupholisa kufuneka buhlangabezane neemfuno ezifanelekileyo.
Ezi ziintlobo ezintathu zeentloboimibhobho yepayipiEnyanisweni, umxholo oxoxwe nguTianjinYuantai Derun Umbhobho wentsimbiIqela liza kuba neenkcukacha ezithe vetshe kwaye lifune ukuqonda okuneenkcukacha. Ngale ndlela, imibhobho yepayipi ingasetyenziswa ngokufanelekileyo, ivumela amashishini ukuba asombulule ezinye iingxaki kwaye adlale indima yawo ngokwenene.
