Production process:High purity synthetic dolomite sand and high purity magnesia as the main raw materials, at the same time add a certain amount of binder, the product is made by mixing.
Main application:Used for ramming the bottom of AC and DC electric furnaces.
Usage method:The use of the product is simple, that is, the bottom of the furnace is laid 100~150mm thick, after vibration and compaction, the surface is shaved once, and then the next laying, and so on. After the construction of the ramming material at the bottom of the furnace is completed, a thin layer of steel plate is laid on its surface to prevent the surface from being damaged when it is loaded into scrap steel or hot metal.
