1. High Chromium cast iron secondary composite roller tayala la zinthu
Chovala chozungulira cha ceramic chokhala ndi chromium yambiri chimapangidwa ndi chitsulo chopangidwa ndi chromium yambiri ngati zinthu za matrix, kudzera mu njira yapadera, chitsulo chopangidwa ndi chromium yambiri ndi tinthu tating'onoting'ono ta ceramic tomwe timapangidwa ndi uchi, tinthu tating'onoting'ono ta ceramic ta ZTA, kenako kudzera mu njira yopangira mchenga, chitsulo chopangidwa ndi chromium yambiri komanso chitsulo chopangidwa ndi ductile. Kapangidwe ka mankhwala ka zinthu zachitsulo chopangidwa ndi chromium yambiri kakuwonetsedwa mu Table 1 pansipa.
Table1: Mankhwala opangidwa ndi chitsulo chopangidwa ndi chromium yambiri (wt%)
| Zinthu Zofunika | C | Si | Mn | S | P | Cr |
| Tayala lozungulira lopangidwa ndi chitsulo chopangidwa ndi ceramic composite lokhala ndi chromium yambiri | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Chitsulo chopangidwa ndi ductile | 3.2-3.9 | 2.5-2.7 | 0.3 ~ 0.5 | ≤0.04 | ≤0.04 |
2. Katundu wa makina
Tayala la ceramic composite roller lomwe lili ndi chromium cast iron ndi lachiwiri lopangidwa ndi chitsulo cha chromium cast, tinthu ta ZTA ceramic ndi ductile iron, zomwe zimapangitsa kuti ceramic composite roller sleeve isakhale ndi mphamvu komanso kuuma kokha, komanso imakhala yolimba kwambiri, zomwe zimapangitsa kuti sleeve ya roller isamavutike komanso kuti ikhale yotetezeka. Kuuma kwa tinthu ta ZTA ceramic kuli pamwamba pa HV2100, pomwe kuuma kwa chromium cast iron M7C3 carbide kuli pamwamba pa HV1400, ndipo kuuma kwa chromium cast iron matrix kuli pamwamba pa HV750, chifukwa chake, pansi pa mkhalidwe wa abrasive high stress bodies two bodies high stress, chifukwa cha kusiyana kwa zipangizo, moyo wa ceramic composite roll sleeve ndi nthawi 1.5-3 kuposa sleeve wamba wa chromium cast iron roll sleeve. Katundu wa chitsulo cha chromium cast ndi ductile iron akuwonetsedwa mu Table 2 pansipa.
Gome 2: Katundu wa Makina
| Zinthu Zofunika | Mphamvu yokoka / Mp | Kulimba kwa Impact J/cm2 | Kuuma/HRC | Mlingo wa Kutalika (%) |
| Chrome Yaikulu | ≥800 | ≥4 | ≥60 | --- |
| Chitsulo Chopangidwa ndi Ductile | 500~650 | ---- | 147~241（HB） | 4~10 |
3. Kapangidwe ka tayala lozungulira la ceramic composite roller lomwe lili ndi chromium yambiri
Kapangidwe ka chigoba cha ceramic composite roller sleeve cha chromium cast iron chawonetsedwa pa Chithunzi 1 ndi Chithunzi 2 pansipa. Malo ofiira a uchi ndi malo ogawa tinthu ta ceramic omwe satha kusweka a ZTA. Tinthu ta ceramic timagawidwa mu matrix ya chromium alloy yapamwamba mu kapangidwe ka uchi, ndipo ceramic layer imaphimba malo ogwirira ntchito a chigoba chonse cha roller sleeve. Malo obiriwira kunja kwa ceramic layer ndi chromium cast iron yambiri, ndipo malo abuluu ndi ductile iron.
