Hauv kev tsim khoom lag luam, qhov kub siab, kev hnav khaub ncaws, thiab kev puas tsuaj ntawm cov tshuaj lom neeg yog cov yeeb ncuab loj tshaj plaws ntawm lub neej ua haujlwm ntawm cov khoom siv thiab kev ua haujlwm zoo. Txawm hais tias nws yog lub cub tawg metallurgical, lub qhov cub tawg cement rotary, lossis lub thawv tshuaj lom neeg, kev ua tau zoo ntawm cov khoom siv refractory ncaj qha txiav txim siab qhov ruaj khov ntawm cov kab ntau lawm. Ntawm ntau cov khoom siv refractory,silicon carbide castablesawv tawm nrog nws qhov kev tiv taus kub siab, kev tiv taus hnav, thiab kev tiv taus corrosion, ua rau cov khoom siv tseem ceeb hauv ntau qhov kev lag luam muaj kev thov siab thoob ntiaj teb.

Silicon carbide castable yog ib hom khoom siv refractory tsis muaj duab uas ua los ntawm cov khoom siv silicon carbide (SiC) uas muaj cov khoom siv tseem ceeb, ua ke nrog cov khoom siv zoo, cov khoom ntxiv, thiab dej. Nws muaj cov yam ntxwv ntawm kev tsim kho yooj yim (tuaj yeem nchuav, troweled, lossis co rau hauv cov duab), muaj zog hloov pauv mus rau cov qauv nyuaj, thiab tuaj yeem tsim cov ntaub ntawv sib xyaw ua ke thiab sib xws tom qab kho thiab sintering. Piv nrog cov cib refractory ib txwm muaj thiab lwm yam castables, nws muaj qhov zoo ntawm kev ua tau zoo, uas tuaj yeem daws tau cov teeb meem ntawm lub neej luv luv thiab kev saib xyuas ntau zaus ntawm cov khoom siv hauv qhov chaw nyuaj.

Cov Ntawv Thov Tseem Ceeb ntawm Silicon Carbide Castable

1. Kev Lag Luam Hlau: Lub Pob Zeb Tseem Ceeb ntawm Kev Smelting Kub Siab

Kev lag luam hlau yog ib qho ntawm cov lag luam loj tshaj plaws rau silicon carbide castable. Hauv cov cub tawg, cov converters, hluav taws xob arc furnaces, thiab cov cub tawg hlau uas tsis yog ferrous (xws li txhuas, tooj liab, thiab zinc smelting), cov linings raug rau cov xwm txheej hnyav xws li kub siab (txog li 1600 ℃), molten hlau yaig, thiab lub cub tawg slag scouring. Silicon carbide castable, nrog nws cov melting point siab (saum toj no 2700 ℃) thiab zoo heev hnav tsis kam, yog dav siv rau hauv lub qhov ncauj ntawm lub cub tawg, tapholes, slag outlets, thiab lwm yam tseem ceeb. Nws tuaj yeem tiv taus qhov yaig ntawm cov hlau molten, hlau, thiab cov hlau uas tsis yog ferrous, txo qhov zaus ntawm kev hloov lining, thiab txhim kho lub sijhawm ua haujlwm tas mus li ntawm lub cub tawg. Piv txwv li, hauv cov cub tawg txhuas smelting, silicon carbide castable yog siv rau lub lining ntawm lub pas dej yaj, uas tuaj yeem tiv taus qhov corrosion ntawm molten txhuas thiab ntev lub neej ntawm lub cub tawg ntau dua 50% piv rau cov ntaub ntawv ib txwm muaj.

2. Kev Lag Luam Khoom Siv Hauv Tsev: Txhawb Kev Ua Haujlwm Zoo ntawm Cement & Ceramic Production

Hauv kev lag luam khoom siv hauv tsev, cov cement rotary kilns, ceramic roller kilns, thiab iav melting furnaces muaj cov kev cai nruj heev rau cov khoom siv refractory. Lub preheater, cyclone separator, thiab tertiary air duct ntawm cement rotary kilns nyob rau hauv qhov kub siab, plua plav, thiab roj-erosion ib puag ncig ntev. Kev siv silicon carbide castable ua lub hauv paus tsis tsuas yog tiv taus qhov kub siab deformation tab sis kuj tiv thaiv tau zoo tiv thaiv kev scouring thiab abrasion ntawm cement clinker thiab plua plav. Qhov no txo ​​cov nqi txij nkawm ntawm lub kaw lus kiln thiab txhim kho kev ua haujlwm ntawm cement. Hauv ceramic roller kilns, silicon carbide castable yog siv rau lub hauv paus ntawm qhov kub siab, uas tuaj yeem hloov kho rau qhov kub hloov pauv sai thaum lub sijhawm ceramic firing thiab xyuas kom meej qhov ruaj khov ntawm qhov kub kiln, yog li txhim kho qhov zoo ntawm cov khoom ceramic.

3. Kev Lag Luam Tshuaj: Kev Tiv Thaiv Kev Xeb Hauv Cov Chaw Ib Puag Ncig Hnyav

Kev lag luam tshuaj lom neeg muaj ntau yam tshuaj lom neeg (xws li cov kua qaub, alkalis, thiab ntsev) thiab cov txheej txheem kub siab. Cov khoom siv xws li cov kais dej kub siab, cov hlawv tshuaj lom neeg, thiab cov tshuab desulfurization roj flue muaj qhov xav tau siab heev rau kev tiv thaiv xeb ntawm cov ntaub ntawv refractory. Silicon carbide castable muaj kev ruaj khov tshuaj zoo heev thiab tuaj yeem tiv taus kev yaig ntawm feem ntau cov kua qaub, alkalis, thiab cov kuab tshuaj organic. Nws yog siv dav hauv cov txheej txheem ntawm cov tshuaj lom neeg, cov kav dej flue, thiab cov ntaub thaiv chimney. Piv txwv li, hauv cov chaw hlawv pov tseg, cov roj flue muaj ntau yam roj corrosive thiab cov khoom me me. Kev siv silicon carbide castable rau cov ntaub thaiv flue tuaj yeem tiv thaiv kev xeb thiab hnav, ua kom muaj kev nyab xeeb thiab ruaj khov ntawm cov txheej txheem kho roj flue.

4. Kev Lag Luam Fais Fab: Txhawb Kev Ua Haujlwm Zoo ntawm Cov Khoom Siv Fais Fab

Hauv kev lag luam fais fab, cov chaw tsim hluav taws xob thermal, cov chaw tsim hluav taws xob biomass, thiab cov chaw tsim hluav taws xob pov tseg txhua yam xav tau cov khoom siv refractory ua haujlwm siab kom ntseeg tau tias kev ua haujlwm zoo ntawm cov khoom siv. Phab ntsa dej boiler, superheater, thiab economizer ntawm cov chaw tsim hluav taws xob thermal raug rau cov pa roj flue kub siab thiab cov tshauv abrasion. Silicon carbide castable yog siv rau cov ntaub thaiv kev hnav ntawm cov khoom no, uas tuaj yeem txo qhov hnav ntawm phab ntsa boiler raj thiab ntev lub neej kev pabcuam ntawm lub boiler. Hauv cov chaw tsim hluav taws xob biomass, vim muaj cov ntsiab lus siab ntawm alkali hlau hauv biomass roj, lub hauv paus cub tawg yooj yim corroded. Silicon carbide castable tuaj yeem tiv taus alkali hlau corrosion, kom ntseeg tau tias kev ua haujlwm ruaj khov ntev ntawm lub cub tawg.
