Zvinoenderana nemaindasitiri zvinyorwa, musika wepasi rose we kumhanya simbi (HSS) maturusi ekucheka anotarisirwa kukura kusvika pamadhora anodarika gumi gumi na2020.Jackie Wang-General Manager weShanghai Histar Metal, anotarisa kuti sei HSS ichiramba iri sarudzo yakakurumbira, nziyo dzakasiyana dziripo uye nemashandisirwo akaitwa indasitiri inokurumidza kuchinja.

Kunyangwe iri kukwikwidza kuri kukura kubva kune yakasimba carbide, HSS inoenderera ichizivikanwa nevakagadziri nekuda kwayo kwakawanda kupfeka kuramba uye kuomarara kwakasimba uye kuomarara zvivakwa. HSS ekucheka maturusi akakodzera zvakanyanya kumatunhu ekugadzirwa kwakawanda uko hupenyu hwechishandiso, kuita kwakawanda, kugadzirwa uye mutengo wezvishandiso ndiwo wakanyanya kukosha kumushandisi-wekupedzisira. Naizvozvo ichiri kutamba chikamu chakakura mukugadzirisa uye kutendeseka kwemuchina wezvinhu zvakawanda.

Zvakare, tarisiro yazvino yehunhu hwakanaka hwechigadzirwa, iyo inosangana nezvinodiwa nevatengi pamutengo usingadhuri, iri kuratidza kukwezva mune yemamiriro ekunze epasi rose ehupfumi.

Kutsigira kukura kuri kudiwa kwepasirese kwe HSS, Kucheka maturusi evagadziri vakazvipira zvakawandisa zviwanikwa kuchikamu chino. Izvi zvinosanganisira kuwedzera mari yekudyara kwete kwete chete nyowani yekugadzirwa kwechigadzirwa asiwo mabasa ekutsvagisa nekusimudzira, izvo zvakatungamira kuti HSS zvishandiso zvive zvakavimbika nekudzikiswa kwehuwandu hwehurema, yakaderera kugadzirwa kwemitengo uye ipfupi kutungamira-nguva. Iko kuwedzerwa kweakagadziridzwa substrates, kusanganisira poda simbi uye machira ave anobatsira mukuwedzera kusimudzira mashandiro.

Shanghai Histar Metal inopa yakakwira yekumhanyisa jira, rakatenderera bhaa uye rakadzika bar. Zvinhu izvi zvinoshandiswa pakuboora, zvinodzikisira, reamers, matepi uye vanogadzira minda.

HSS kuumbwa

Iyo yakajairika HSS yekuumbwa inoratidzira chromium (4%), tungsten (approx. 6%), molybdenum (kusvika 10%), vanadium (kutenderedza 2%), cobalt (inosvika 9%) uye kabhoni (1%). Mhando dzakasiyana dzegiredhi dzinoenderana nematanho akasiyana ezvinhu zvakawedzerwa.

Chromium inovandudza kuomesa kugona uye inodzivirira kuyerwa. Tungsten inopa hukuru hwekucheka kugona uye kuramba kune tempering, pamwe nekuvandudza kuomarara uye kwakanyanya tembiricha simba. Molybdenum - a-chibereko chemhangura uye tungsten kugadzirwa - zvakare inovandudza kutema kugona uye kuomarara, pamwe nekudzivisa kutsamwa. Vanadium, iyo irimo mune akawanda mamineral, inoumba yakaoma kwazvo carbides yeakanaka arrasive kupfeka kuramba, inowedzera yakanyanya tembiricha yekupfeka kuramba uye simba, pamwe nekuchengetedza kwekuomarara.

Cobalt inovandudza kupisa kupisa, kuchengetedza kweukukutu uye zvishoma inovandudza kupisa kupisa, nepo kabhoni, inowedzera kupfeka kuramba uye inokonzeresa kuomarara kwekutanga (ingangoita 62-65 Rc). Iko kuwedzerwa kwe5-8% yakawanda cobalt kuHSS kunovandudza simba uye kupfeka kuramba. Kazhinji, madhiraivha akagadzirwa pamwe nekuwedzeredzwa kweakawanda cobalt anoshandiswa mukushandisa chaiko mashandiro.

Zvakanakira

HSS maturusi anokwanisa kuramba kudedera, chero mhando remuchina chishandiso, kunyangwe kana kuomarara kwarasika nekufamba kwenguva uye zvisinei nebasa chidimbu chekupomba mamiriro. Inogona kudzivirira zvemaziso kushamisika panguva zino pamwero azvikuya akavhiyiwa uye kutsungirira siyana lubrication ezvinhu zvinogona kukonzera chafariz kuchinja.

Zvakare, nekuda kwesimba reiyo HSS, vagadziri vezvishandiso vanogona kuburitsa micheto yakapinza yekucheka. Izvi zvinoita kuti zvive nyore kumuchina zvinhu zvakaoma, zvinopa mashoma basa kuomesa kweaustenitic simbi isina simbi uye nickel alloys, uye inopa zvirinani pamusoro pehunhu uye shiviriro yezvikamu zvakagadzirwa.

Sezvo simbi yacho yakatemwa uye isina kubvaruka, inopa hupenyu hwakareba hwechishandiswa netembiricha dzakadzika-dzepakati. Izvo zvinoda zvakare kudzikisa ekucheka masimba, ayo pakupedzisira anoreva kushoma kwesimba kushandiswa kubva kumushini chishandiso. Kubva pane chishandiso chehupenyu hwekutarisa, HSS inoita nemazvo chaizvo nepakati-pekucheka kunyorera.

Pfupiso

Muzera umo vashandisi vanoda maturusi akavimbika, anowirirana, akasiyana-siyana pamutengo unodhura, kumhanya simbi ichiri sarudzo yakanaka kune akawanda maficha. Nekudaro, inogona kuramba yakazvibata yayo pamusika ichipesana nevechidiki uye zvehunyanzvi zvigadzirwa zvemberi.

Kana paine, HSS ane anopfuura makore mazhinji akasimba nekuzvichinjisa neanguye machira matsva, kugadzirisa kuumbwa kwayo uye nekuwedzera tekinoroji nyowani, zvese zvichibatsira kuchengetedza chinzvimbo chayo sechinhu chakakosha muindasitiri yekucheka simbi.

Iyo yekucheka chishandiso chikamu indasitiri yagara iri yemakwikwi nzvimbo uye HSS inoramba iri chinhu chakakosha kupa vatengi izvo zvagara zviri chinhu chakakosha chisarudzo: sarudzo yakanaka.
