Steel flow agent with common what are the four types of drainage sand sand
Ladle drainage with our common what are the four types of drainage sand, ladle drainage with our common what are the four
types of drainage sand, ladle drainage with common four types of drainage sand steel flow in drainage sand there are four
basic requirements:
Drainage sand in the ladle nozzle for a long time in high temperature condition, for sintering layer high refractoriness;
Drainage sand filling nozzle after direct contact with the molten steel, initial sintering temperature is unfavorable and
exorbitant.
In use process, drainage sand steel under high static pressure, to prevent stretch material, required drainage sand has the
very good liquidity, small friction between the particles as far as possible.
Drainage sand under high temperature condition, prevent drainage sand automatic whereabouts or in use process can not
effectively support the upper material.Based on the above requirements, meet have four classes in the practical application
of common drainage sand: magnesium olive stone, silica sand, zircon and chrome conduction.
