Cold Ramming Paste Invention
The invention relates to a cold ramming paste method for preparing electrolytic aluminum, in which one or several kinds of mixed aggregate are first grinded by crushing ball and then entered into screening equipment to obtain aggregate powder with particle size of 50 ~ 300μm. At the same time, one or several mixed adhesives are heated and melted to obtain the molten solution of adhesives; Then the aggregate powder and binder melt in accordance with the weight ratio of 5 to 20:1 ratio has been poured into the mixing and kneading machine for full mixing, keep the mixing and kneading temperature of 80 ~ 200℃, the time of mixing and kneading is 1 ~ 18h, the mixing and kneading good material out and into the molding machine for molding processing, get the specified size of cold ramming paste products; Aggregate is common calcined anthracite, calcined anthracite, high carbon graphite, metallurgical coke or petroleum coke in one or several mixtures, the carbon content of various aggregates is not less than 95%; The binder is a mixture of one or more of phenolic resin, furfural resin, epoxy resin, furan resin, asphalt, coal tar or anthracene oil.
