Figure shows three reference cycles conducted in the years 2008, 2009 and 2012, showing no loss in performance over the complete testing phase.
Get PriceThermal conductivity represents the amount of heat per in unit area, unit time and unit temperature gradient in the energy transfer process. At 1000 ℃The thermal conductivity of various refractory bricks rate as shown below. The thermal conductivity of different materials is often very different.
Get PriceFigure 2 Estimated Average Blast Furnace capacity on a country basis (and regional for China) is correlated to the average Estimated Fuel Rate. India has on average, the smallest Blast Furnaces, and as a consequence higher fuel rates. Figure 3 Compares the estimated slag generation, Lime and Dolomite additions. These rates are based on the ...
Get PriceMineral wool insulation (also called stone, rock or slag wool insulation) Made from rock, blast furnace slag, and other raw materials which are melted and spun into fibers to resemble the texture of wool. Mineral wool comes in batts, rolls, or loosefill forms.

Get PriceStone wool insulation is composed principally of fibres manufactured from a combination of aluminosilicate rock (usually basalt), blast furnace slag and limestone or dolomite. Stone wool resists temperatures up to 1177°C (2150°F). It can reduce the spread of fire and provides valuable extra minutes to save people and property, and reduce environmental
Get PriceFireproof Blanket Properties. Such fireproof blanket is excellent in thermal insulation because of its superior insulation properties, low heat storage capacity and low thermal conductivity, which is one of the important performance in heat insulation. In addition, it is resistant to thermal shock, for the flexibility and tensile strength,...
