Spinel ramming mass how to use

Spinel ramming mass is a semi-dry, ramming bulk refractory. Usually, the granules and fine powders made of high-aluminum materials are made of a certain gradation and added with an appropriate amount of binder. During construction, ramming is required to obtain a dense structure.

When the Spinel ramming mass is fired, the moisture content is about 5%. Use the furnace building machine to make solid charging materials, and then dry in the shade for a period of time (there is also a 500-watt light bulb in the furnace). Before starting the furnace, turn on the low-power oven 7 After 8 hours, after the moisture is basically dried, heat the charge to 500-700 degrees and start smelting after 7 to 8 hours of baking. Generally, the molten steel is first smelted so that the high temperature will make the furnace lining sintered better. The temperature is generally controlled at 1680 degrees.
Spinel ramming mass has the characteristics of strong slag erosion resistance, good thermal shock stability, high refractoriness and high temperature strength, and is more and more favored by ladle users.
Spinel ramming mass for ladle is made of high-quality fused spinel, super-high alumina bauxite clinker, nano-level additives and other materials.
