1. Chromium cast iron secondary composite roller tire material
Chishongo chesimbi chakagadzirwa nesimbi yakagadzirwa nechromium yakawanda sematrix, kuburikidza nemaitiro akakosha, simbi yakagadzirwa nechromium yakawanda uye honeycomb ceramic particles composite molding, ceramic ZTA ceramic particles, uye zvakare kuburikidza nesand casting process, chromium yakawanda cast iron ceramic composite uye ductile iron secondary composite molding. Kuumbwa kwemakemikari esimbi yakagadzirwa nechromium yakawanda kunoratidzwa muTafura 1 pazasi.
Tafura 1: Kuumbwa kwemakemikari e roller ine chromium yakawanda (wt%)
| Zvinhu | C | Si | Mn | S | P | Cr |
| Tayara ine chromium yakawanda yakakandwa nesimbi yakagadzirwa neceramic composite roller ine chromium yakawanda | 2.8-3.2 | 0.5-1.0 | 0.5-1.2 | ≤0.05 | ≤0.05 | 20-26 |
| Simbi yesimbi | 3.2-3.9 | 2.5-2.7 | 0.3~0.5 | ≤0.04 | ≤0.04 |
2. Zvivakwa zvemakanika
Taya resimbi rine chromium cast iron rine ductile iron, ZTA ceramic particles uye ductile iron, zvinoita kuti ceramic composite roller sleeve isangove nesimba chete, asiwo yakasimba, zvichiita kuti sleeve yesimbi ine chromium cast iron irambe yakasimba uye yakachengeteka. Kuomarara kwesimbi ine chromium cast iron ine M7C3 carbide kuri pamusoro peHV1400, uye kuomarara kwesimbi ine chromium cast iron iri pamusoro peHV750, saka, kana yave ne pressure abrasive miviri, nekuda kwekusiyana kwezvinhu, hupenyu hwe ceramic composite roll sleeve hwakapetwa ka1.5-3 kupfuura hwe chromium cast iron roll sleeve. Hunhu hwesimbi ine chromium cast iron ine ductile iron hunoratidzwa muTafura 2 pazasi.
Tafura 2: Zvivakwa zveMichina
| Zvinhu | Simba rekusimba /Mp | Kusimba Kwemhedzisiro J/cm2 | Kuoma/HRC | Mwero weKureba (%) |
| Chrome Yakanyanya | ≥800 | ≥4 | ≥60 | --- |
| Ductile Simbi | 500~650 | ---- | 147~241（HB） | 4~10 |
3. Dhizaini yechimiro chetairi resimbi rine chromium yakawanda
Magadzirirwo echimiro che sleeve ye ceramic composite roller sleeve ine chromium cast iron inoratidzwa muMufananidzo 1 neMufananidzo 2 pazasi. Nzvimbo yehuchi dzvuku inzvimbo yekugovera ceramic particles isingatsvedzeri ZTA. Zvidimbu zve ceramic zvinogoverwa mu chromium alloy matrix ine chromium alloy muchimiro chehuchi, uye ceramic layer inofukidza nzvimbo yekushanda ye roller sleeve yese. Nzvimbo yegirini iri kunze kwe ceramic layer ine chromium cast iron yakawanda, uye nzvimbo yebhuruu i ductile iron.
