Iziqhamo zensimbi ezinzima
Izinhlaka zensimbi ezishisayo ezibandayo
Ithanda ubunzima obuphezulu be-surface (55-85HSD) kanye nokumelana okuhle kwe-core, futhi isetshenziswa ekugudlweni kwe-wire rods kanye nezigaba.
I-ductile iron rolls
Lo mkhiqizo we-roller unokuhlanganiswa okuphezulu kwe-nickel-molybdenum alloy. Isakhiwo sayo se-matrix siqukethe i-acicular bainite matrix, i-graphite ye-spherical kanye ne-carbides. Ubunzima bukhula ngokwanda kokuhlanganiswa kwe-carbide. Ama-roller akhiwe kahle anokuphikisana okuhle, futhi ukumelana nokuphuka okushisayo kungathuthukiswa kakhulu ngemuva kokwelashwa kokushisa. Ngasikhathi sinye, umehluko wobunzima phakathi kwe-layer yokusebenza yomzimba we-roller uncane, ukumelana nokugqoka kuphezulu, futhi ukuvuma nokwakheka kuhlangene. Ikakhulukazi isetshenziswa emishinini yokugaya eqhubekayo ye-steel yesigaba, emishinini yokugaya eshisayo yamapayipi, ukugaya kwe-bar kanye ne-wire rods, ukugaya okuphakathi, ukugaya kokuphela kokuphuma kanye nemishini yokugaya yokugcina. Ngaphezu kwalokho, ukumelana nokugqoka nokuphuka kwayo kuhle kakhulu kunezokhuni ezibandayo ezinzima, futhi ivame ukusetshenziswa kumaroli asekelayo agaywe ngokuqinile.
Izinhlaka ze-centrifugal composite eziphezulu ze-chromium ezicwecwezelwe ngensimbi.
Ishidi langaphandle lenziwe ngensimbi ye-chromium ephezulu (Cr11-20%) kanti ishidi langaphakathi lenziwe ngensimbi eyenziwe. Ukumelana nokugqoka kukhuphukile ngo-30%, futhi ubunzima bungafinyelela ku-60-95HSD. Kufaneleka emgqeni wesibili wokushisa, ekugcineni kokushisa kokupholisa, nasezindaweni zokusebenza zezimboni zokugaya ezishisayo. Ngemuva kokuthi imboni yensimbi yasekhaya isebenzise le msebenzi, isikhathi sokushintsha izinduku sande sathathwa sibe yizinkulungwane eziyi-800.
