Lime wash adhesion is little possesses the stork for casting and is used

摘要

PROBLEM TO BE SOLVED: To provide a stoke having strength, wear resistance, corrosion resistance and thermal shock resistance necessary for a cast member, and also having economical efficiency, durability and consistent quality while any slag is hardly deposited thereon.;SOLUTION: In the casting stoke with the slag deposition preventive function and its manufacturing method, the stoke is used for casting molten aluminum, and has unevenness including a large number of polygonal pyramids, spherical projections, groove and/or holes in a strip-shaped area forming a part in contact with slag floating at least in the vicinity of the level of the molten aluminum. The part having the unevenness is filled with inorganic substances as necessary. Since the inorganic substances are filled in the projections and holes on the surface, bonding with a base metal is increased, and the crack propagation in a thick film is suppressed thereby. Further, in the member for the molten aluminum with the slag deposition preventive function, the slag is hardly deposited thereon and the quality is consistent.;COPYRIGHT: (C)2008,JPO&INPIT
