Iiphampu ye-slurryiyiphampu edlulisa ingxube yezinto eziqinile namanzi. Ngakho-ke, i-medium izoba yi-abrasive ezingxenyeni ezigelezayo zepompo ye-slurry. Ngakho-ke, izingxenye ezigelezayo zepompo ye-slurry zidinga ukwenziwa ngezinto ezingagugi.

Izinto ezisetshenziswa kakhulu zensimbi zamaphampu anodaka zihlukaniswa zibe yinsimbi eyinsimbi, i-ductile iron, i-chromium cast iron ephezulu, insimbi engagqwali, njalonjalo. I-chromium cast iron ephezulu iyisizukulwane sesithathu sezinto ezingagugi ezithuthukiswe ngemuva kwensimbi evamile emhlophe ekhonjiwe kanye ne-nickel hard cast iron. Ngenxa yezimpawu zesakhiwo se-chromium cast iron ephezulu, inokuqina okuphezulu kakhulu, amandla aphezulu okushisa, ukumelana nokushisa, nokumelana nokugqoka kunensimbi evamile ekhonjiwe. Insimbi ephezulu ye-chromium iye yanconywa njengento engcono kakhulu evimbela ukuhubeka esikhathini samanje, futhi isetshenziswe kakhulu usuku nosuku.

Izinga kazwelonke laseShayina lensimbi emhlophe engagugi (GB/T8263) icacisa izinga, ukwakheka, ubulukhuni, inqubo yokwelapha ukushisa, nezici zokusetshenziswa kwensimbi emhlophe ye-chromium ephezulu.

Izinga eliphezulu le-chromium cast iron ephezulu e-United States yi-ASTMA532M, i-United Kingdom BS4844, Germany DIN1695, ne-France NFA32401. I-Russia ithuthukise ama-mill mill linener angu-12-15% Cr, 3-5.5% Mn kanye no-200mm endaweni eyayiyiSoviet Union, futhi manje isebenzisa izinga le-ҐOCT7769.

Izinto eziyinhloko ezisetshenziselwa izingxenye ezigelezayo zamaphampu e-slurry ekhaya naphesheya insimbi engagqwali, i-chromium cast iron ephezulu, ne-nickel hard cast iron. I-chromium cast iron ephezulu iyinto efanelekile yezingxenye ezigelezayo zamaphampu anodaka. Ngokulungiswa noma ukukhethwa kwamazinga wokuqukethwe kwekhabhoni ne-chromium, imiphumela engcono kakhulu yokusebenzisa yezingxenye ezigelezayo ngaphansi kwezimo ezihlukene zezimboni nezezimayini ingatholakala.

I-high chromium cast iron isifinyezo se-high chromium white anti-wear cast iron. Kuyinto ephikisana nokugqoka esebenza kahle kakhulu nokunakwa okukhethekile; inokumelana nokugqokwa okuphakeme kakhulu kunensimbi ye-alloy kanye nokuqina namandla aphakeme kakhulu kunensimbi evamile emhlophe ekhonjiwe. Ngesikhathi esifanayo, futhi inokumelana okuhle nezinga lokushisa eliphezulu kanye nokugqwala, okuhambisana nokukhiqiza okulula kanye nezindleko ezimaphakathi, futhi yaziwa njengenye yezinto ezihamba phambili zokunqanda ukubola ezikhathini zanamuhla.

Manje Kuvame ukusetshenziswa uchungechunge lwezinto eziphakeme ze-chromium cast iron resistant:

Amaphampu anodaka enziwe ngezinto ze-A05 (Cr26) yiwona asetshenziswa kakhulu embonini yezimayini. I-microstructure ye-high chromium alloy A05 ibonisa ukuthi iqukethe i-hard eutectic chromium carbides ku-matrix yesayithi ye-marten eqiniswe ngokuphelele. Ezinhlelweni zephampu ezinodaka lapho kokubili kuhubeka futhi kugqwala kodwa kuhuzuka, ukusebenza kwalokhu okubalulekile kungcono kakhulu kunezinye izinsimbi ezisansimbi ezimhlophe.

Nakuba izingxenye ezimanzi ezenziwe nge-A07 (Cr15Mo3) zinokumelana nokugqokwa okuphezulu, ubulukhuni obungcono, nempilo yesevisi ende kune-A05, izindleko zazo ziphindwe kabili kune-A05, ngakho ukusebenza kwezindleko kuphansi futhi ububanzi bokusetshenziswa buncane.

I-A49 (Cr30) empeleni iyi-chromium ephansi ye-carbon iron cast iron cast. I-microstructure i-hypoeutectic futhi iqukethe i-eutectic chromium carbides ku-matrix ye-austenite/martensite. Okuqukethwe kwekhabhoni kwe-chromium A49 ephezulu kungaphansi kwalokho kwe-chromium A05 ephezulu. Kukhona i-chromium eningi ku-matrix. Endaweni ene-acidic ebuthakathaka, i-chromium A49 ephezulu inokumelana nokugqwala okuphezulu kune-chromium A05 ephezulu.

Okwamanje, okubalulwe ngenhla yizinto zensimbi ezivame ukusetshenziswa kuumphakeli wamaphampu odaka. Ngokuhambisana nemininingwane yendawo ehanjiswayo, sizokhetha into efanelekile kakhulu.
