Iziqhamo zensimbi ezishisayo

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

Lolu hlobo lwezinto zokugaya lunokuhlanganiswa okuphezulu kwe-nickel-molybdenum alloy. Isakhiwo sayo siqukethe i-acicular bainite matrix, i-graphite ye-spherical kanye ne-carbides. Ubunzima bukhula ngokwanda kokuhlanganiswa kwe-carbide. Ama-rolls akhishiwe anokuphila okuhle kokushayisana, 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 nokwakha kuyahambisana. Ikakhulukazi isetshenziswa emishinini yokugaya eqhubekayo ye-steel yesigaba, emishinini yokugaya eshisayo yamapayipi, ekugayeni kwe-bar kanye ne-wire rods, ukugaya okuphakathi, ukugaya kokuphela kokuphuma nokugaya kokuphothulwa. Ngaphezu kwalokho, ukumelana nokugqoka nokuphuka kwayo kuphakeme kunezokhuni ezishisayo ezibandayo, futhi ivame ukusetshenziswa kumaroli asekelayo agaywe ngokuqinile.

Izinhlaka ze-centrifugal composite eziphezulu ze-chromium zensimbi ezicijile

Iphakethe langaphandle lenziwe nge-high-chromium cast iron (Cr11-20%) kanti iphakethe langaphakathi lenziwe nge-cast steel. Ukumelana nokugqokwa kwanda ngo-30%, futhi ubunzima bungafinyelela ku-60-95HSD. Kufaneleka emgqeni wesibili wokushisa, ukugaya kokugcina kokushisa okuphansi kanye nezinsimbi zokusebenza ze-tropical continuous rolling mills. Ngemuva kokuthi imboni yensimbi yasekhaya isebenzise le msebenzi, isikhathi sokushintsha izinsimbi sande safa sathola ku-800 tons.
