PROBLEM TO BE SOLVED: To provide a rotary wheel type continuous extrusion device capable of suppressing mixing of oxides in a product to be extruded by suppressing the flow of dead metal formed in an assembly chamber. SOLUTION: The rotary wheel type continuous extrusion device 1a comprises a material feed passage 7 formed between a rotary wheel 5 and a fixed shoe 6, an abutment 8 to gate and highly pressurize a material 2 at a termination of the material feed passage 7, an assembly chamber 9 which is connected to the abutment 8 and expanded toward the distal side from an inlet 9a so as to uniformly pressurize the highly-pressurized material 2, and a die 12 which is provided in the assembly chamber 9 and has a working hole 11 formed to extrude the uniformly pressurized material 2 as a product 10. The die 12 is formed so that the inlet 11a of the working hole 11 is located in a vicinity of the inlet 9a of the assembly chamber 9. COPYRIGHT: (C)2005,JPO&NCIPI
