NKHANI

Nyundo yapamwamba ya chromium alloy ya Zhejiang Shanvim Industrial Co., Ltd. Ili ndi zitsulo zamtengo wapatali monga molybdenum, vanadium, nickel ndi niobium. Pambuyo mankhwala madzi toughening mankhwala, ndi processing kuuma kwambiri bwino. Kukana kwabwino kwa abrasion, kukana kwa okosijeni kutentha kwambiri, kukana kwa dzimbiri komanso kulimba kwabwino komanso kugwira ntchito kwazitsulo zotayidwa zimaphatikizidwa. Ili ndi kukana kovala bwino komanso kukana kwamphamvu komwe kumakhala kovuta kukwaniritsa ndi chinthu chimodzi chachitsulo. Ili ndi magwiridwe antchito onse a nyundo zachitsulo zapamwamba za manganese, ili ndi mawonekedwe olimba kwambiri, kutulutsa bwino komanso kukana kuvala kwambiri. Matrix olimba kwambiri a martensite mu nyundo amathandizira kwambiri tinthu tating'ono ta carbide kuti ateteze carbide kuti isagwe pansi pakugwira ntchito, kuonetsetsa kuti zinthuzo Kukana kwa abrasion, kuuma kumatha kufikira 62HRC-65HRC.
Malinga ndi zomwe amapanga, zimagawidwa kukhala nyundo zoponyera ndi nyundo zopangira
Malinga ndi zinthu za nyundo: mkulu chromium nyundo, mkulu manganese zitsulo nyundo, bi zitsulo nyundo, gulu nyundo, nyundo yaikulu golide, simenti carbide nyundo, etc.
1. High chromium alloy nyundo
Nyundo ya chophwanyira chapamwamba cha alloy imakhala ndi kulimba kwambiri ndipo ndi yamtengo wapatali yosamva kuvala. Zakhala zikugwiritsidwa ntchito kwambiri mu crusher yabwino (makina opangira mchenga wa m'badwo wachitatu) ndi chopondapo chokhala ndi chimango chothandizira nyundo, koma kulimba kwa chromium alloy Inferior, ndikosavuta kusweka popanda kuthandizidwa ndi nyundo. Sagwiritsidwa ntchito kawirikawiri pakadali pano.
2. High manganese zitsulo nyundo
Nyundo yachitsulo yapamwamba ya manganese imakhala ndi kulimba kwabwino, luso lopanga bwino komanso mtengo wotsika. Cholinga chake chachikulu ndi chakuti pansi pa kukhudzidwa kwakukulu kapena kupsinjika maganizo, kusanjikiza pamwamba kumatulutsa mwamsanga ntchito yowumitsa, ndipo ndondomeko yake yowumitsa ntchito ndi 5-7 kuposa zipangizo zina. M'kupita kwanthawi, kukana kwamphamvu kumawonjezeka kwambiri. Komabe, nyundo ya chitsulo chophwanyira manganese imakhala ndi zofunikira zapamwamba pakuchita kwathunthu kwa crusher. Ngati mphamvu yakukhudzidwa kwa thupi sikokwanira kapena kupsinjika kwa kukhudzana kuli kochepa pantchito yeniyeni, pamwamba sikungagwire ntchito mwachangu molimba, motero kulephera kuwonetsa kukana kwake koyenera kuvala.
3. Nyundo yamagulu
Nyundo yophatikizika ndi njira yapadera yopangira yomwe imagwiritsidwa ntchito popanga zinthu. Chogwirizira cha nyundo cha mutu wa nyundo chophatikizika chimapangidwa ndi chitsulo chokwera cha manganese, ndipo gawo la nyundo limapangidwa ndi aloyi wapamwamba wa chromium, omwe amaphatikiza kulimba ndi kukana kuvala, kupangitsa kuti gawo la chogwirira cha nyundo zisagwire ntchito. Kugonjetsedwa pang'ono ndi abrasion, kuphatikizidwa ndi ubwino wa kukana kwachitsulo cha manganese kukhudzidwa ndi kuvala, ndi kukana kwa ma chromium alloy avale.
4. Tungsten-titaniyamu alloy nyundo
Tungsten-titanium alloy nyundo ndi chida chonyezimira chachitsulo chomwe chimagwiritsa ntchito vacuum kuwirikiza, kuyenga kunja kwa ng'anjo, komanso ukadaulo wowongolera wokhazikika. Imagwiritsa ntchito chitsulo chapamwamba kwambiri cha manganese chapamwamba kwambiri ngati nyundo. WTI/C wowonjezera zitsulo zolimba (tungsten-titanium alloy, kuuma kwake ndi kwachiwiri kokha kwa diamondi yokumba). Choncho, sikuti amangotengera ubwino wa kuuma kwakukulu, kudalirika kwakukulu ndi kukana kwabwino kwa kuvala kwachitsulo choyambirira chapamwamba kwambiri chapamwamba cha manganese, komanso chimakhala ndi kukana kowonjezereka kwa aloyi a tungsten-titaniyamu.
5 Nyundo yolimba ya alloy
Poyerekeza ndi zipangizo zina, nyundo za simenti za carbide zimakhala ndi kuuma kwakukulu, kusinthasintha kwa ural mphamvu ndi mphamvu, kukana kutopa kwa kutentha, kuuma kwabwino kwa kutentha, ndi zina zotero, zomwe zimathetsa ming'alu, kuwononga, kupukuta, ndi ming'alu yomwe imakonda kwambiri zipangizo zamphamvu. Kutayika kwa midadada ndi zina zotero. Ili ndi ntchito zosiyanasiyana ndipo imatha kusinthidwa ku mafakitale onse ophwanya.
