Musiyano uripo pakati peYT mhando neYG type cemented carbide

Cemented carbide inoreva alloy material yakagadzirwa nerefractory metal compound sematrix uye transition metal sebinder phase, yozogadzirwa nepowder metallurgy method. Inoshandiswa zvakanyanya mumotokari, zvekurapa, zvechiuto, kudzivirirwa kwenyika, aerospace, avhiyesheni uye mamwe minda. . Zvakakosha kucherechedza kuti nekuda kwemhando dzakasiyana uye zviri mukati me refractory metal carbides uye mabinders, iyo yemuviri uye kemikari zvimiro zveakagadzirirwa simende carbides zvakare akasiyana, uye iwo ma mechanic uye emuviri zvimiro zvinonyanya kuenderana nerudzi rwesimbi carbide. Zvinoenderana neyakasiyana-siyana zvikamu, simende carbide inogona kukamurwa kuita YT mhando uye YG mhando simende carbide.
Kubva pane tsananguro yemaonero, YT-type cemented carbide inoreva tungsten-titanium-cobalt-type cemented carbide, iwo makuru matungsten carbide, titanium carbide uye cobalt, uye zita rechiratidzo ndi "YT" ("yakaoma, titanium" mazwi maviri Chinese Pinyin prefix) Inoumbwa neavhareji yemukati yetitanium carbide, seYT15, zvinoreva kuti avhareji yemukati yetitanium carbide i15%, uye imwe yese inosimwa carbide ine tungsten carbide uye cobalt zvirimo. YG-mhando cemented carbide inoreva tungsten-cobalt-mhando simende carbide. Izvo zvakakosha zvinoumba tungsten carbide uye cobalt. Semuenzaniso, YG6 inoreva tungsten-cobalt carbide ine avhareji yecobalt ye6% uye imwe yasara tungsten carbide.
Kubva pakuita kwemaonero, ese YT neYG simende carbides ane yakanaka kugaya kuita, kubhenda simba uye kuoma. Izvo zvinofanirwa kucherechedzwa kuti kupfeka kuramba uye kupisa kwemafuta eYT-mhando cemented carbide uye YG-mhando simende carbide yakatarisana. Iyo yekutanga ine zvirinani kupfeka kuramba uye kushomeka kwemafuta conductivity, nepo iyo yekupedzisira ine kushomeka kwekusagadzikana uye yekupisa conductivity. zvakanaka. Kubva pakuona kwekushandisa, YT type cemented carbide inokodzera kutendeuka kwakashata, rough planing, semi-finishing, rough milling uye drilling of discontinuous surface apo chikamu chisina kuenzana che carbon steel uye alloy simbi inochekwa zvishoma nezvishoma; YG mhando yakaoma alloy Inokodzera kutendeuka kwakashata mukuenderera mberi kwekucheka kwesimbi yakakandwa, simbi isina-ferrous uye alloys avo uye zvisiri-metallic zvinhu, semi-kupedzisa uye kupedzisa mukucheka kwepakati.
Kune nyika dzinopfuura makumi mashanu pasi rose dzinogadzira simende carbide, ine huwandu hwakazara hwe27,000-28,000t-. Vagadziri vakuru iUnited States, Russia, Sweden, China, Germany, Japan, United Kingdom, France, etc. Musika wepasi rose we carbide wakazara. , makwikwi emusika anotyisa zvikuru. Indasitiri yeChina yakasimwa carbide yakatanga kuumbwa mukupera kwema1950. Kubva kuma1960 kusvika kuma1970, indasitiri yeChina yakasimwa carbide yakasimukira nekukurumidza. Mukutanga kwema1990, huwandu hwese hwekugadzira hweChina hwesimende carbide hwakasvika 6000t, uye huwandu hwesemented carbide yakasvika 5000t, yechipiri chete kuRussia neUnited States, iri pachinhanho chechitatu pasi rose.
