SiC rollers thiab beams
ZPC-RBSiC (SiSiC) cov kab hla thiab cov menyuam muaj zog dua thiab tsis muaj kev hloov pauv txawm tias nyob rau hauv qhov kub siab heev. Thiab tseem muaj cov kab ua haujlwm ntev. Cov kab yog cov rooj tog zaum hauv qhov cub uas tsim nyog tshaj plaws rau kev hnav khaub ncaws huv thiab cov ntawv thov hluav taws xob porcelain. RBSiC (SiSiC) muaj kev ua tau zoo heev, yog li nws muaj los txuag hluav taws xob nrog qhov hnyav tsawg dua ntawm lub tsheb qhov cub.
Cov kab teeb thiab cov menyuam roj hmab silicon carbide siv ua cov thav duab thauj khoom hauv cov qhov cub ua porcelain, thiab lawv tuaj yeem hloov cov phaj silicon oxide bonded thiab mullite post ib txwm vim lawv muaj cov txiaj ntsig zoo xws li txuag chaw, roj, zog thiab luv lub sijhawm tua hluav taws, thiab lub neej ntawm cov ntaub ntawv no yog ntau zaus ntawm lwm tus nws yog cov rooj tog zaum zoo tshaj plaws hauv qhov cub. Cov kab teeb silicon carbide feem ntau yog siv ua cov khoom thauj ntawm qhov av qhov cub, qhov cub shuttle thiab qhov cub ob chav. Nws kuj tseem siv tau ua rooj tog hauv qhov cub hauv kev lag luam ceramic thiab refractory.
Cov nqaj hlau uas muaj peev xwm ua tau qhov kub siab thiab siv tau ntev yam tsis muaj kev khoov deformation, tshwj xeeb tshaj yog rau cov qhov cub qhov av, lub qhov cub shuttle, hauv ob txheej qhov cub roller thiab lwm yam khoom siv rau lub cub tawg. Cov qws siv rau cov khoom siv ceramics siv txhua hnub, cov khoom siv porcelain huv, Cov khoom siv Ceramic, Cov khoom siv sib nqus thiab thaj chaw kub siab ntawm cov qhov cub roller.

Shandong Zhongpeng Special Ceramics Co., Ltd yog ib qho ntawm cov khoom siv tshiab silicon carbide ceramic loj tshaj plaws hauv Suav teb. SiC technical ceramic: Moh qhov nyuaj yog 9 (New Moh qhov nyuaj yog 13), nrog kev tiv thaiv zoo heev rau kev yaig thiab xeb, kev puas tsuaj zoo heev - kev tiv thaiv thiab kev tiv thaiv oxidation. SiC cov khoom lub neej kev pabcuam yog 4 txog 5 zaug ntev dua li 92% alumina khoom. MOR ntawm RBSiC yog 5 txog 7 zaug ntawm SNBSC, nws tuaj yeem siv rau cov duab nyuaj dua. Cov txheej txheem hais nqe yog ceev, kev xa khoom yog raws li tau cog lus tseg thiab qhov zoo yog qhov thib ob rau tsis muaj leej twg. Peb ib txwm mob siab rau kev sib tw peb lub hom phiaj thiab muab peb lub siab rov qab rau lub zej zog.
