摘要： PURPOSE:To join thoroughly the outside layer material and inside layer material of a composite roll and to prevent the variance of quality by forming preliminarily the outside layer material into a hollow shape and pouring a molten metal into the hollow part to form the core material. CONSTITUTION:The outside layer material 4 of the roll having a prescribed size is installed to the projecting part of a dummy bar and an integral cylindrical metallic mold 3 provided with a high-frequency induction heating coil 8 is installed around said material. A sealing cover 6 is attached thereto and gaseous Ar is blown from a gaseous Ar blow-off nozzle 7 and is blown off through a blow-off nozzle 9. The preheating by the coil 8 is stopped when the material 4 attains the prescribed temp. A long nozzle is inserted from the upper part of the cover 6. The molten metal is poured to the inside surface side of the material 4 in a non-oxidizing atmosphere and is pressurized by a plunger 11. The molten metal is pressurized by plungers 11, 13 after a jig 2 for holding the dummy bar is opened to lower the dummy bar 1 and the composite roll along guide rolls 14. The heated composite roll is cooled with cooling water nozzles 15.

摘要： PURPOSE:To increase remarkably an occupying rate by contg. a material to be embedded by casting into a refractory vessel than charging a base metal of a material for embedding by casting into a space part and heating the vessel from the outside to melt the base material thereby embedding the above-mentioned material by casting. CONSTITUTION:A material to be embedded by casting, for example, a pipe 01, is installed in a refractory vessel 9 and after system sand 03' is compacted into the bottom part on the inside surface side, green sand 03 is charged therein and finally the system sand 03' is compacted. A flux 04 is coated by brushing on the outside surface side of the pipe 01 and is then dried. A material 08 for embedding by casting which is a non-ferrous material is charged into the vessel 9 and the material 08 is melted by a high-frequency induction coil 10 enclosing the outside periphery of the vessel 9. The pipe 01 is thus embedded by casting and the composite pipe casting is produced.

摘要： PURPOSE:To eliminate the need for a special device for preheating a material to be embedded by casting by forming a coating layer of a surface treating agent on the surface of said material and forming a coating layer of an exothermic material in superposition thereon then embedding said material by casting a molten material for embedding by casting. CONSTITUTION:A coating layer 6 of a surface treating agent is formed on the surface of a material to be embedded by casting, for example, a pipe 1, and further a coating layer 7 of an exothermic material is formed on the surface thereof. A casting mold 4 is then formed and after the pipe 1 is installed into the mold 4, casting sand 3 kneaded with a furan resin, etc. is introduced into the pipe 1 and is compacted. A molten metal 8 is thereupon poured through a sprue 5 into the mold to embed the pipe 1 by casting, thus producing a composite pipe casting. The coating layer may be of one layer consisting of a mixture composed of the surface treating agent and exothermic material without forming the same of the above-described two layers.

摘要： PURPOSE:To uniformly pour molten metal toward direction and to prevent crack caused by heat stress by setting one pair of bending refractory plates as facing which the upper part is bent along the top roll and the lower part is flat. CONSTITUTION:One pair of the refractory plates 10, 10' are bent along the top rolls 3, 3' at the upper part 10a, 10'a flattened at the lower part 10b, 10'b and extended downward between one pair of belts and set as facing. Molten metal from tundish nozzles 11, 11' is spread as layer-state to width direction on the surface of bending upper parts 10a, 10'a of the refractory plates 10, 10' and flowed downward on the refractory plates 10, 10' to introduce to the pouring face 8. By this method, uniform pouring of the molten metal is executed to width direction. Further, as the refractory plates 10, 10' are not restrained to both sides of width direction, the construction, which the heat stress is easily released and the crack is difficult to occur, is obtd.
