Which is more suitable for the lining of lime rotary kilns, silicon-magnesia bricks or special phosphate bricks?

For the lining bricks of lime rotary kilns, when it comes to silicon-magnesia bricks and special phosphate bricks, special phosphate bricks are more suitable. Because the high-temperature zone of the lime kiln lining is an oxidizing atmosphere, and the lining atmosphere is alkaline. One reason is that silicon-magnesia bricks are fired in a reducing atmosphere and are not very suitable for use in an oxidizing atmosphere. The second one is the silicon carbide added in the process ratio of silicon-magnesia bricks. Silicon carbide has high strength and wear resistance, but its drawback is that it is somewhat brittle. When used in the inner lining of lime rotary kilns, it may cause head explosion (that is, bricks fall off the working surface). In addition, due to its high thermal conductivity, the outer cylinder of the lime kiln is hot to the touch. Generally, manufacturers that use silicon-magnesia bricks usually adopt silicon-magnesia composite bricks. Silicon-magnesia composite bricks are heavy on the working surface and light on the large surface. During the firing process, if different materials are fired at the same temperature, dimensional deviations may occur. Under the same temperature, different materials At low temperatures, the heavy part of silicon carbide does...

What kind of refractory material is suitable for the lining of the rich manganese slag molten iron ladle?

The rich manganese slag molten iron ladle forms in an acidic environment, and the slag as a whole is subject to weak acid and neutral erosion, while manganese is alkaline and will accelerate chemical penetration erosion. The composition of the rich manganese slag molten iron ladle is basically a ratio of 2:1 of rich manganese slag and molten iron. Under this complex erosion atmosphere, choosing the material for the ladle lining is extremely crucial.   Generally, refractory bricks are used as the lining more frequently. When using refractory bricks as the lining, it is necessary to consider the erosion atmosphere. Clay bricks and high alumina bricks have weak anti-erosion capabilities and are not recommended. The slag line area has a high ratio of slag to iron, and the slag volume accounts for a large proportion. The slag line area is a severely damaged area. If using refractory bricks as the lining, it is best to choose aluminum-carbon silicon carbon bricks. The characteristics of aluminum-carbon silicon carbon bricks are stability and suitability for frequent thermal cycling use.   The best lining material for the ladle is clay bricks or grade three high alumina bricks as the permanent layer, water glass combined...
