HSS ni iki?

Icyuma cyihuta cyane (HSS) nicyo gipimo cyibikoresho byo gutema ibyuma kuva 1830.

Icyuma cyihuta cyane (HSS) nigikoresho cyicyuma gifite ubukana bwinshi, kwihanganira kwambara cyane, no kurwanya ubushyuhe bwinshi. Yitwa kandi ibyuma bikarishye, bivuze ko ishobora gukomera no gukomeza gukara nubwo ikonje mu kirere mugihe cyo kuzimya.

Icyuma cyihuta kirimo ijanisha ryinshi rya karubone nibindi byuma. Urebye ko ibihimbano aribyo byingenzi biranga ibyuma byihuta, HSS irimo tungsten, molybdenum, chromium, vanadium, cobalt, nibindi bintu bigize karbide muburyo bwa 10 kugeza kuri 25% byibintu bivangavanze. Ibi bihimbano bitanga HSS hamwe no gukata ibintu bisanzwe hamwe nubukanishi nko kurwanya kwambara. Mugihe kizimye, icyuma, chromium, s ome tungsten, hamwe na karubone nyinshi mubyuma byihuta bikora karbide ikomeye cyane ishobora kunoza imyambarire.

Mubyongeyeho, HSS izwiho kugira ubushyuhe bukabije. Ibi ni ukubera ko tungsten yashonga muri matrix. Ubukonje bushyushye bwibyuma byihuta birashobora kugera kuri dogere 650. Tungsten, molybdenum, chromium, vanadium, cobalt, nizindi karbide zirimo ibintu bifasha kugumana ubukana bwinshi mugukata ubushyuhe bwinshi (hafi 500 ° C).

Kugereranya HSS nibikoresho bya karubone birashobora kumenya bifite ubukana burenze ubushyuhe bwicyumba nyuma yo kuzimya no gutwarwa nubushyuhe buke. Ariko iyo ubushyuhe buri hejuru ya 200 ° C, ubukana bwibikoresho bya karubone bizagabanuka cyane. Byongeye kandi, ubukana bwibikoresho bya karubone kuri 500 ° C bizamanuka kurwego rusa nubwa leta yegeranye, bivuze ko ubushobozi bwo guca ibyuma bwatakaye rwose. Iyi phenomenon igabanya ikoreshwa ryibikoresho bya karubone mugukata ibikoresho. Ibyuma byihuta byuzuza urufunguzo rwibanze rwibikoresho bya karubone kubera ubukana bwabyo bwiza.

Carbide ya sima iruta HSS mubihe byinshi. Niba ukunda ibicuruzwa bya tungsten kandi ukaba ushaka ibisobanuro birambuye, urashobora kutwandikira kuri terefone cyangwa ubutumwa ibumoso cyangwa UKOHEREZA MAIL US hepfo yurupapuro. Dutegereje ibibazo byawe.
