1. Izinto zethayi le-roller elihlanganisiwe le-Chromium ephezulu
Isiketi se-roller se-ceramic esihlanganisiwe esine-chromium ephezulu senziwe ngensimbi ehlanganisiwe ene-chromium ephezulu njengezinto ezibonakalayo, ngenqubo ekhethekile, insimbi ehlanganisiwe ene-chromium ephezulu kanye nezinhlayiya ze-honeycomb ceramic, izinhlayiya ze-ceramic ze-ZTA ze-ceramic, bese kuba ngenqubo yokuphonsa isihlabathi, i-composite ye-ceramic yensimbi ehlanganisiwe ene-chromium ephezulu kanye ne-ductile iron yesibili. Ukwakheka kwamakhemikhali kwezinto zensimbi ehlanganisiwe ene-chromium ephezulu kuboniswe kuThebula 1 ngezansi.
Ithebula 1: Ukwakheka kwamakhemikhali kwe-roller yensimbi ehlanganisiwe ene-chromium ephezulu (wt%)
| Izinto | C | Si | Mn | S | P | Cr |
| Ithayi le-roller elihlanganisiwe le-ceramic eliyi-chromium ephezulu | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Insimbi ethambile | 3.2-3.9 | 2.5-2.7 | 0.3~0.5 | ≤0.04 | ≤0.04 |
2. Impahla yemishini
Ithayi le-roller elihlanganisiwe le-chromium cast iron ephezulu liwukubumba kwesibili okuhlanganisiwe kwe-chromium cast iron ephezulu, izinhlayiya ze-ceramic ze-ZTA kanye ne-ductile iron, okwenza i-ceramic composite roller sleeve ingabi namandla nobunzima obuphezulu kuphela, kodwa futhi inokuqina okuphezulu, okuqinisekisa ukumelana nokuguguleka kanye nokuphepha kwe-roller sleeve. Ukuqina kwe-ZTA ceramic particle kungaphezu kwe-HV2100, kuyilapho ubunzima be-chromium cast iron M7C3 carbide bungaphezu kwe-HV1400, kanti ubunzima be-chromium cast iron matrix obuphezulu bungaphezu kwe-HV750, ngakho-ke, ngaphansi kwesimo sokucindezeleka okuphezulu ukuguguleka kwemizimba emibili okucindezelekile, ngenxa yomehluko wezinto zokwakha, impilo yenkonzo ye-ceramic composite roll sleeve iphindwe ka-1.5-3 kune-standard high chromium cast iron roll sleeve. Izakhiwo ze-chromium cast iron ephezulu kanye ne-ductile iron ziboniswe kuThebula 2 ngezansi.
Ithebula 2: Impahla Yomshini
| Izinto | Amandla okudonsa /Mp | Ukuqina Komthelela J/cm2 | Ubulukhuni/i-HRC | Izinga Lobude (%) |
| I-Chrome ephezulu | ≥800 | ≥4 | ≥60 | --- |
| Insimbi Ehlanganisiwe | 500~650 | ---- | 147~241（HB） | 4~10 |
3. Ukwakheka kwesakhiwo sethayi le-roller elihlanganisiwe le-ceramic eline-chromium ephezulu
Umklamo wesakhiwo se-high chromium cast iron ceramic composite roller sleeve uboniswe kuMfanekiso 1 kanye noMfanekiso 2 ngezansi. Indawo ye-honeycomb ebomvu yindawo yokusatshalaliswa kwezinhlayiya ze-ceramic ezingagugi ze-ZTA. Izinhlayiya ze-ceramic zisatshalaliswa ku-high chromium alloy matrix esakhiweni se-honeycomb, kanti ungqimba lwe-ceramic lumboza indawo yokusebenza yokugqoka ye-roller sleeve yonke. Indawo eluhlaza ngaphandle kwengqimba ye-ceramic iyi-high chromium cast iron, kanti indawo eluhlaza okwesibhakabhaka iyi-ductile iron.
