According to the present invention, the size of a rolled material guiding device is reduced, and the opening degree and retention force of a guide roller are individually adjusted. In a support unit (20) of the rolled material guiding device (10): a coupling member (23) that is screw-coupled to a roller holder while a rotational direction about a rotation support shaft (13) on the other end side of the roller holder (14) is used as an axial line, and that can adjust the position of the support unit with respect to the roller holder in the rotational direction, a cushion part (26) that can slide in the rotational direction with respect to the coupling member, and a second elastic member are provided between the coupling member and the cushion part so that an acting direction of an elastic force of the second elastic member (27) substantially coincides with a sliding direction of the cushion part; and a holding member (35) includes an engagement part (32a) that engages with the coupling member or the cushion part to restrict the amount of protrusion of the cushion part from the coupling member in the sliding direction, and an adjustment screw that adjusts the elastic force of the second elastic member (27) while the engagement part engages with the coupling member or the cushion part.
A refrigerant processing device includes a main body, and a pipe and a narrow tube that feed a refrigerant into and out of the main body. The main body has a cylindrical body part, and upper and lower end wall parts that close both ends of the cylindrical body part. The pipe passes through the lower end wall part, and extends along a central axis of the cylindrical body part. The narrow tube passes through the upper end wall part. A first spiral groove extending in a spiral shape with respect to the central axis is formed on an inner circumferential surface of the cylindrical body part. A second spiral groove extending in a spiral shape with respect to the central axis and a linear groove extending in a direction of the central axis are formed on an outer circumferential surface of the pipe.

The present invention prevents generation of a hydrogen compound in a refrigerant and regenerates a radical in the refrigerant into a compound constituting a refrigerant. A refrigerant processing device 100 is provided with: a body 110 having a cylindrical barrel part 110a, and an upper end wall part 110b and a lower end wall part 110c that close both end parts of the barrel part 110a; and a tube part 114 and a thin tube 112 that introduce a refrigerant into the body 110 or derive the refrigerant from the inside of the body. The tube part 114 is provided in the lower end wall part 110c so as to pass through the lower end wall part 110c and extends along a center axis of the barrel part 110a. The thin tube 112 is provided in the upper end wall part 110b so as to pass through the upper end wall part 110b. A spiral groove 116 spirally extending relative to the center axis is formed on an inner peripheral surface of the barrel part 110a. A spiral groove 118 spirally extending relative to the center axis and a linear groove 119 extending in the direction of the center axis are formed on an outer peripheral surface of the tube part 114.
The purpose of the invention is to improve the quality of a rod-shaped steel material by preventing the generation of scratches on the rod-shaped steel material, and to obtain a stable ring shape. First to third guides (G1, G2, G3) are disposed to guide the rod-shaped steel material from pinch rolls (P) to a laying head (H). The first guide (G1), on the most upstream side, is provided with a plurality of bending and shaping roller guides (G11, G12) which impart a curvature to the rod-shaped steel material, bending it in the direction of the laying head (H). The second guide (G2) is provided with a plurality of directing roller guides (G21, G22) which guide the rod-shaped steel material downstream. The third guide (G3), on the most downstream side, is contiguous with the second guide (G2) and is provided with a plurality of bending-back and shaping roller guides (G31, G32) for bending back the rod-shaped steel material in the direction of the laying head (H), to make it straight.
