Wopanga njerwa zapamwamba za alumina

Ordinary high alumina bricks are divided into LZ-75, LZ-65, LZ-55, LZ-48 grades according to physical and chemical indicators. High alumina refractory bricks have high refractoriness, high load softening temperature, good thermal shock stability, acid resistance, Anti-alkali, anti-erosion and other characteristics.

2. Kugwiritsa ntchito ndi zizindikiro zofananira za njerwa zapamwamba za alumina m’mafakitale osiyanasiyana:

1. High alumina bricks for general purpose: Generally, high alumina bricks are made of bauxite clinker, supplemented by combined clay and additives.

2. Njerwa zapamwamba za alumina zopangira ng’anjo yophulika: Njerwa zapamwamba za alumina zopangira ng’anjo yophulika zimagwiritsa ntchito bauxite clinker ngati chinthu chachikulu chopangira, chopangidwa ndi kuponderezedwa kwakukulu ndi kutentha kwakukulu kwa sintering. Mchere waukulu wa mchere ndi mullite ndi corundum.

3. High-alumina bricks for steel-making electric furnace roofs: High-alumina bricks for steel-making electric furnace roofs are made of specially selected special grade bauxite clinker as the main raw material, which is formed by high-pressure forming and high-temperature sintering.

4. High alumina bricks for steel drums: High alumina bricks for steel drums are made of selected Yangquan bauxite as the main raw material, formed by high-pressure forming and high-temperature sintering. The main mineral composition is corundum and mullite phases. Good high temperature mechanical properties and chemical resistance.

5. Low creep series high alumina bricks for hot blast stoves: Low creep series high alumina bricks for hot blast stoves are made of corundum mullite and selected bauxite clinker as the main raw materials, through high pressure forming and high temperature sintering.

6. Njerwa zotsika za andalusite zopangira masitovu otentha: Zopangira ndi ukadaulo: njerwa zotsika komanso zotsika kwambiri za mbaula zotentha zimagwiritsa ntchito andalusite, corundum, ndi mullite ngati zida zazikulu zopangira, ndipo zimapangidwa ndi kuumba kwamphamvu komanso kutentha kwambiri. kuimba.

7. Njerwa za mullite za ng’anjo yophulika:

8. a. Mullite bricks:

Zopangira ndi ukadaulo: Njerwa za Mullite zopangira ng’anjo yophulika zimagwiritsa ntchito zopangira zosakanikirana kapena za sintered mullite monga zida zazikulu zopangira, zomwe zimapangidwa ndi kuumba kwamphamvu kwambiri komanso kutentha kwambiri. Mchere waukulu wa mchere ndi mullite.

8. Corundum mullite brick for blast furnace: composite brown corundum brick

Zomwe sizikhala zodula ndi zabwino, zomwe zili zoyenera kwa inu ndizabwino kwambiri. Utumiki woyimitsa umodzi kwa inu panthawi yonseyi, “Gwiritsani ntchito, timathetsa vutoli” ndilolonjezano lathu losasintha!
