Chii chinonzi HSS?

High-speed simbi (HSS) yanga iri chiyero chemidziyo yekucheka simbi kubva kuma1830s.

High-speed simbi (HSS) isimbi yemudziyo ine kuoma kwepamusoro, kupfeka kwepamusoro, uye kupisa kwakanyanya. Inonziwo simbi yakapinza, zvinoreva kuti inogona kuomesa uye kuramba yakapinza kunyange kana yatonhodzwa mumhepo panguva yekudzima.

Simbi yepamusoro-soro ine chikamu chepamusoro chekabhoni nedzimwe simbi. Tichifunga kuti kuumbwa ndiko kwakakosha hunhu hwesimbi inomhanya-mhanya, HSS ine tungsten, molybdenum, chromium, vanadium, cobalt, uye zvimwe zvinhu zvinogadzira carbide muhuwandu hunosvika gumi kusvika 25% hwealloying elements. Aya manyorerwo anopa HSS neyekare yekucheka uye michina zvimiro senge kupfeka kuramba. Pakudzima, iron, chromium, s    ome tungsten, uye yakawanda kabhoni musimbi inomhanya zvikuru zvinoumba carbides yakaoma zvakanyanya inogona kunatsiridza kusakara kwesimbi.

Pamusoro pezvo, HSS inozivikanwa kuve ine yakanyanya kupisa kuomarara. Izvi zvinodaro nekuti tungsten inonyungudika mumatrix. Kuoma kunopisa kwesimbi yepamusoro-soro kunogona kusvika 650 degrees. Tungsten, molybdenum, chromium, vanadium, cobalt, uye mamwe macarbides ane zvinhu zvinobatsira kuchengetedza kuoma kwepamusoro pakutema kwepamusoro-tembiricha (inenge 500 ° C).

Kuenzanisa HSS kune kabhoni mudziyo simbi inogona kuziva kuti ndeapi ane kuomarara kwepamusoro pakamuri tembiricha mushure mekudzimwa uye kudzikiswa pakudziya kwakaderera. Asi kana tembiricha yakwira kupfuura 200°C, kuoma kwesimbi yecarbon tool kunodonha zvakanyanya. Uyezve, kuoma kwekabhoni tool steels pa 500 ° C ichadonha kusvika kune imwe nhanho kune iyo yeannealed state, izvo zvinoreva kuti kukwanisa kwayo kutema simbi yakarasika zvachose. Ichi chiitiko chinomisa kushandiswa kwekabhoni mudziyo simbi mukucheka maturusi. Simbi dzepamusoro-soro dzinogadzira kukanganisa kwakakosha kwekabhoni mudziyo simbi nekuda kwekunaka kwayo kunopisa kuoma.

Cemented carbide inopfuura HSS muzviitiko zvakawanda. Kana iwe uchifarira tungsten carbide zvigadzirwa uye uchida rumwe ruzivo uye ruzivo, unogona KUBATA NESU nerunhare kana tsamba kuruboshwe kana KUTITUMIRA MAIL pazasi peji. Tinotarisira kubvunza kwako.
