Xov xwm

High-alumina cib rau blast furnaces yog ua los ntawm high-qib bauxite raws li lub ntsiab raw khoom, uas yog batched, nias, qhuav thiab raug rho tawm ntawm kub. Lawv yog cov khoom siv refractory siv rau hauv ob sab phlu blast furnaces.

2. Qhov twg yog qhov siab alumina cib siv nyob rau hauv blast furnaces?

High-aluminium bricks yog tsim rau ntawm lub cub tawg ncej ntawm lub qhov cub tawg. Lub qhov cub tawg yog nyob rau sab sauv ntawm lub qhov cub tawg. Nws txoj kab uas hla maj mam nthuav tawm los ntawm sab saum toj mus rau hauv qab kom hloov mus rau lub thermal expansion ntawm tus nqi thiab txo qhov kev sib txhuam ntawm lub cub tawg phab ntsa ntawm tus nqi. Lub cub tawg lub cev occupies lub blast furnace. 50% -60% ntawm qhov siab zoo. Nyob rau hauv ib puag ncig no, lub cub tawg yuav tsum tau ua kom tau raws li cov kev xav tau, thiab cov yam ntxwv ntawm alumina cib siab yog siab refractoriness, siab softening kub nyob rau hauv load, acid tsis kam, alkali tsis kam, muaj zog tiv taus slag yaig, thiab zoo hnav tsis kam. Nws tuaj yeem txaus siab, yog li nws yog qhov tsim nyog rau lub tshuab hluav taws xob tawg rau lub cev kom ua rau muaj kev kub siab alumina cib.

Cov saum toj no yog kev taw qhia rau siab alumina cib rau blast furnaces. Lub hauv paus ib puag ncig ntawm lub qhov cub tawg yog qhov nyuaj thiab muaj ntau hom khoom siv refractory siv. High alumina cib yog ib qho ntawm lawv. Muaj 3-5 specifications ntawm siab alumina cib siv. Robert lub siab alumina cib tuaj yeem siv rau hauv ntau qhov cub. Yog tias tsim nyog, thov hu rau peb.
