Chii chinonzi scraper blade yakagadzirwa?
Zviri mukati
Wolfram carbide
Tungsten carbide ikamu rinoumbwa ne50% tungsten uye 50% kabhoni. Kune nzira dzakati wandei dzinoshandiswa kugadzira musanganiswa, iyo inonyanyo zivikanwa ndeye kupindirana kwesimbi tungsten nekabhoni patembiricha kubva 1400 kusvika 2000 ° C. madigiri Celcius.High speed steels
High speed simbi (HSS) ialloy inosanganisa simbi (simbi nekabhoni) nezvimwe zvinhu zvakaita sechromium, molybdenum, tungsten, vanadium kana cobalt. Zvinhu kunze kwesimbi zvinogona kuita kusvika 20% yeHSS kuumbwa, asi zvinogara zvichipfuura 7%.Kuwedzera zvinhu izvi kune simbi hazvigadzirise HSS, zvinhu zvacho zvinofanirwa kunge zvichidziya uye kudzikiswa.
Yekumhanya simbi (HSS) inokwanisa kucheka zvinhu nekukurumidza kupfuura yakakwira kabhoni simbi, nekudaro zita rekuti "kumhanya". Izvi zvinokonzerwa nekuoma kwayo kukuru uye kuramba kwebrasion zvichienzaniswa nekabhoni yakakwira uye mamwe masimbi emidziyo.
Sei simbi yekumhanya uye carbide ichishandiswa kune scraper blades?
Iyo scraper blade inofanirwa kugadzirwa nechinhu chakaoma kupfuura icho chiri kukwesha kuti chishande. Kuwedzera alloying zvinhu uye nzira dzekugadzira, senge yekupisa kurapwa iyo inomhanyisa simbi inoiswa pasi, ipe iyo kuomarara kunodiwa pakukwenya.
Carbide scrapers yakaoma kupfuura HSS. Izvi zvinobvumira kuti zvishandiswe pane zvakatowanda zvezvinhu.
Non-replaceable scraper blades
Non-replaceable scraper blades inenge nguva dzose yakagadzirwa nesimbi yakakurumidza, sezvo mari yekugadzira blade yose uye shaft kunze kwecarbide ingave yakakwirira.Kunyange zvazvo mashizha asina kuchinjwa anogadzirwa nesimbi yakakurumidza, chikamu chiduku chete pamagumo e-scraper chinopisa uye chinopisa. Iyo inopisa inobatwa uye nzvimbo yakadzikama inowanzosiyana nemuvara kubva kune imwe shaft.
Ndezvipi zvinhu zvinogona kushandiswa scraper blades?
