Kev faib tawm ntawm cov ntaub ntawv refractory rau cement rotary kiln

1. Lub qhov ncauj qhov cub 0.6m yog ua los ntawm corundum hnav-resistant castable;

Lub hauv ntej kiln hauv ob sab phlu ntawm cov cement rotary kiln yog ib qho kev sib txuas tsis muaj zog ntawm ntau lub teb kiln. Nyob rau hauv cov txheej txheem ntau lawm ntawm lub teb kiln, kev khiav hauj lwm lub voj voog ntawm lub kiln hauv ob sab phlu nruj me ntsis txwv lub neej kev pab cuam ntawm tag nrho cov kiln. Tsis tas li ntawd, kev tsim kho ntawm kiln khawm thiab kiln hauv ob sab phlu kuj yog qhov nyuaj dua. Casting siv feem ntau siv corundum hnav-resistant castable. Corundum hnav-resistant castable tsis tsuas yog muaj zog hnav tsis kam thiab siab kub tsis kam, tab sis kuj muaj cov tshuaj tiv thaiv zoo thiab thermal poob siab. Qhov tseem ceeb tshaj, nws yog qhov yooj yim dua los tsim nrog refractory castables. Cov xwm txheej zoo li no tuaj yeem ua rau lub neej ua haujlwm ntawm lub boiler tau yooj yim dua. Kev tshawb xyuas qhia tau hais tias cov qauv siv cov khoom siv corundum hnav-resistant castable muaj qhov nruab nrab kev pab cuam lub neej ntawm ntau tshaj 8 lub hlis.

1 meter cua sov cheeb tsam,

5-meter sib txawv cheeb tsam siv silicon mullite cib;

21.4-meter preheating cheeb tsam txais kev tiv thaiv kev poob siab aluminium cib;

25-meter firing cheeb tsam txais yuav magnesia chrome cib;

20-meter kev hloov chaw txais yuav spinel cib; qhov chaw txias thiab hloov chaw ntawm 0.8m ntu ntawm cov txheej txheem tshiab cov cement kiln tuaj yeem xaiv silicon mullite cib lossis HMS siab hnav-tiv taus cib.

2. 1m steel fiber hnav-resistant castable ntawm lub qhov ncauj kiln

Piv nrog rau yav dhau los cov tsoos rotary kiln, qhov kub ntawm qhov me me qhov cub feem ntau qis dua 1000 ° C, thiab tuaj yeem ncav cuag li 700 ° C; Qhov kub ntawm lub qhov cub loj loj yog siab li 1100 ° C, thiab qhov cub tawg feem ntau tsis muaj qhov tshwm sim ntawm tawv nqaij. Rau kilns uas muaj cov ntsiab lus siab alkali los yog ib qho me me ntawm high-sulfur thee nyob rau hauv cov zaub mov nyoos, cov khoom xws li alkali, sulfur, thiab chlorine yog pheej rov evaporated thiab accumulated, ua rau lub Cheebtsam los ua crust yam ntxwv minerals, yog li tsim crusts ntawm lub cov khoom siv kiln, uas muaj kev cuam tshuam zoo rau kev tsim khoom thiab kev ua haujlwm hauv qab ntawm lub boiler. Los ntawm peb qhov kev sim tsis tu ncua, nyob rau xyoo tas los no, kev siv cov hlau fiber ntau hnav-tiv taus castables lossis siab-aluminium hnav-resistant castables hauv cov teb kilns yuav zoo dua.
