Coating metal mold centrifugal casting pipeCoating metal mold centrifugal casting tube, also known as hot molding centrifugal cast pipe, the earliest development and use of this technology is a German dick (Duker) company, its structure is characterized by metal mold without a jacket, the host does not make the horizontal motion, use short chute, performance characteristics in the moldSpray a layer of surface coating, can be obtained without white as-cast centrifugal tube, this machine has simple structure, low cost, the replacement of mold is convenient, and the mold life is long, cast pipe diameter is not restricted, can produce grey iron tube and iron tube ball.The resin sand lined centrifugal cast pipeResin sand lined centrifugal process is characterized by hang a layer from the surface of metal type resin as binder sand line, metal mold, life can be enhanced greatly and can be obtained without white as-cast centrifugal tube, especially suitable for large diameter ball iron pipe production.
odular, can avoid the frequent replacement operation, improve the working efficiency to significantly improve the quality of steel strip surface.Of hearth roll of these two kinds of new material, use for a long time also not easy to wear and tear, is carbon life set of 3 to 5 times, and used the old furnace bottom roller can also be reprocessed to use repeatedly, substantially reducing the costs of production.The characteristics of the radiation tube and its effect.And the use of temperature can be as high as 1100 degrees Celsius, suitable for high grade of silicon steel continuous annealing furnace.
