I-Forgings ye-Cones ye-drill Bit ikuluhlu lwe-Welong Supply Chain.Izinto ekrwada forgings kungenziwa ngokwezifiso ngokweemfuno umxhasi.Ngokomzekelo, ibakala lensimbi i-AISI 9310, ngokwe-US standard SAE J1249-2008, ingasetyenziselwa njengento ekrwada yokubumba.I-AISI 9310 yensimbi yi-American standard ye-SAE / AISI ukutyunjwa kwaye iphantsi komgangatho ophezulu we-alloy high-high-strength steel.Ihambelana nebakala eliqhelekileyo laseTshayina 10CrNi3Mo ngokubhekiselele kwimichiza.Intsimbi ye-AISI 9310 ibonisa ukomelela okuphezulu, ukuqina, ukuqina, kunye namandla okudinwa, nto leyo eyenza ukuba isetyenziswe ikakhulu kwizixhobo ze-aerospace, iigiya zeblade ye-iturbine, kunye nezinto zomkhosi.Ngokwenza unyango lobushushu be-carburizing, i-AISI 9310 yentsimbi inokufumana iipropathi ezigqwesileyo zoomatshini, ziyenze ilungele iigiya, iishafti, iintshulube, iibholiti, kunye nezitudi ezisebenza phantsi kweemeko zomthwalo ophezulu.Ngokuqhelekileyo, imijikelezo eqingqiweyo ihanjiswa ngendlela ye-hot-forged kunye ne-annealed.
Ngeemfuno ze-cones forgings, inkqubo yokwenziwa kwesiqhelo ibandakanya ukufakela, umatshini orhabaxa, kunye nokuqhelekileyo.Ukuqhubekeka okongeziweyo nako kunokwenziwa ngokweemfuno zabathengi.Xa usebenzisa izinto eziphathekayo ze-AISI9310, kufuneka zihambelane neemfuno zokubunjwa kunye neenkcukacha ezichazwe kumgangatho we-SAE J1249-2008.Imfuneko eqhelekileyo yeecones kukuba ubushushu kufuneka bufikelele kwi-954.44℃.Inkqubo yokwenziwa kwesiqhelo ibandakanya ukubeka ifoloji kwiziko emva kokuba ubushushu ngaphakathi bufikelele kuma-350℃.Isithando somlilo sifudunyezwa ukuya kuthi ga kwi-954.44℃±10℃ kwaye sigcinwe kobu bushushu iiyure ezi-2 phambi kokuba sipholiswe ngumoya.Emva kokugqitywa kwe-normalizing, i-curve epheleleyo ye-normalizing kufuneka inikezelwe.Ukuqhubela phambili ukucwangciswa kweecones kwenziwa ngokusekelwe kwimizobo yabathengi.Ukunyamezela komatshini okusebenzayo kuhambelana ne-ISO 2768-MK umgangatho.
Ukuba unayo naziphi na iimfuno okanye umbuzo malunga Forgings for iiCones of drill Bit, nceda uzive ukhululekile ukuqhagamshelana nathi (Welong Supply Chain).
