Prodotti Deskrizzjoni
L-ewwel grad għoli alumina brick is a a newtrali refrattarju materjal with an alumina kontenut ta mhux inqas minn 75%. It is formed u kalċinati minn alumina jew oħrajn materja prima ma għoli alumina kontenut. It has good thermal stability and refrattarji fuq 1770 degree . It has good slag resistance and is maprinly used for lining blast furnaces, electric furnaces tops, blast furnaces, furnaces, reverberatory furnaces and fran li jduru .
Prodotti Speċifikazzjonijiet
Fi addition, high alumina bricks are also widely used as open-hearth regenerative checker bricks, plugs for pouring systems, nozzle bricks, etc. Physical and chemical properties of general high alumina bricks (i.e. T-head bricks), forma speċjali għoli alumina bricks and blast furnace bricks
1. Kompressiv saħħa: Skont għal klijent paraguni, l-ewwel livell għoli alumina briks huma ġeneralment 10~15 MPa ogħla minn it-tieni livell għoli alumina briks at l-istess l-istess piż u l-istess aluminju kontenut.
2. Thermal conductivity: Under the condition of unit temperature gradient, the heat flow rate through the unit area of the material is related to the porosity.
3. Impact resistance: Good impact resistance means long service life.
4. Slag reżistenza: il kapaċità biex jirreżisti l-erożjoni of imdewweb gagazza at temperaturi għoljin mingħajr ma jkun jinqered.
