Izwi rakajairwa rezvishandiso zvesimbi zvine simba rinoramba kupfeka, kupfeka-inodzivirira simbi ndiyo inonyanya kushandiswa mhando yezvigadzirwa zvinopfekwa nhasi.

Classification

Kune mhando dzakawanda dzesimbi isingabatike, inogona kupatsanurwa kuita yakakwira manganese simbi, yepakati uye yakaderera alloy kupfeka-resistant simbi, chrome-molybdenum-silicon-manganese simbi, cavitation-resistant simbi, kupfeka-inomira simbi uye yakakosha kupfeka. -resistant simbi.Mamwe masimbi akajairwa alloy akadai sesimbi isina simbi, inotakura simbi, alloy chishandiso simbi uye alloy chimiro chesimbi anoshandiswawo sesimbi isingapfekere pasi pemamiriro chaiwo.Nekuda kwenzvimbo yavo yakareruka uye kuita kwakanakisa, ivo vanoshandiswawo mukushandiswa kwesimbi isingapfekere.imwe muzana.

makemikari anoumbwa

Masimbi epakati uye akaderera aloy anodzivirira anowanzo aine makemikari zvinhu zvakaita sesilicon, manganese, chromium, molybdenum, vanadium, tungsten, nickel, titanium, boron, mhangura, isingawanzo pasi, nezvimwewo. Mamiriro ezvigayo zvebhora zvakakura uye zvepakati nepakati. muUnited States dzakagadzirwa nechrome-molybdenum-silicon-manganese kana chrome-molybdenum simbi.Mazhinji emabhora ekukuya muUnited States akagadzirwa nepakati uye yakakwira kabhoni chrome molybdenum simbi.Kune maworkpieces anoshanda pasi peabrasive kupfeka mamiriro ekushisa kwepamusoro (senge 200 kusvika 500 ° C) kana maworkpiece ayo anotaridzika ari pasi petembiricha yepamusoro nekuda kwekupisa kunopisa, alloys senge chrome-molybdenum-vanadium, chrome-molybdenum-vanadium-nickel. kana chrome-molybdenum-vanadium-tungsten alloys inogona kushandiswa.Kukuya simbi, mushure memhando iyi yesimbi yakadzimwa uye yakanyoroveswa pane yepakati kana yakakwirira tembiricha, kune yechipiri kuomarara.

application

Simbi isingapfeki inoshandiswa zvakanyanya mumichina yemigodhi, migodhi yemarasha uye yekufambisa, michina yekuvaka, michina yekurima, zvekuvakisa, michina yemagetsi, yekufambisa njanji nemamwe madhipatimendi.Semuyenzaniso, mabhora esimbi, mahwendefa ezvigayo zvebhora, mazino emugomo uye mabhakiti evacheri, madziro edhaka anokunguruka, ndiro dzemazino nesando misoro yemacrusher akasiyana-siyana, shangu dzetirakita nematangi, mahwendefa ezvigayo, njanji ruts Forks, pakati. groove-in-plates, grooves, denderedzwa cheni dze scraper conveyors mumigodhi yemarasha, mashizha nemazino emabulldozers, linings emagetsi emagetsi mabhaketi erori, roller cone bits ye perforating mafuta uye opencast iron ore, nezvimwewo. inogumira pakushandiswa kwesimbi isingachinjiki iyo inoiswa pasi pekupfeka abrasive, uye marudzi ese ezvishandiso zvine hukama nekufamba mumakina akasiyana anoburitsa marudzi akasiyana-siyana ekupfeka, izvo zvichavandudza kushorwa kwezvinhu zveworkpiece.Zvido zvekugadzika kana kushandiswa kwesimbi isina kupfeka, mienzaniso yakawanda.Iyo yekukuya midhiya (mabhora, tsvimbo uye liner) inoshandiswa mune ore uye simende zvigayo zvakanyanya kushandiswa kwesimbi kupfeka zvikamu.MuUnited States, mabhora ekukuya anonyanya kuumbwa kana kukandwa nekabhoni uye alloy steels, ayo anotora 97% yehuwandu hwekukuya bhora rinoshandiswa.MuCanada, mabhora esimbi anoita 81% yemabhora ekukuya anopedzwa.Maererano nenhamba mukupera kwema1980, kudyiwa kwepagore kweChina kwemabhora ekukuya kunosvika 800,000 kusvika miriyoni imwe matani, uye kudyiwa kwepagore kwechigayo linings munyika yose anoda kusvika 200,000 matani, mazhinji acho ari zvigadzirwa zvesimbi.Mugero wepakati we scraper conveyor mumugodhi wemarasha weChina unodya 60,000 kusvika ku80,000 matani emarata esimbi gore rega rega.
