    Abstract: Provided are a side member from which a clad member for heat exchanger exhibiting excellent productivity and corrosion resistance while preventing poor adhesion can be produced in production of a clad member for heat exchanger by controlling the surface state and flatness, a method for producing the side member, and a method for producing a clad member for a heat exchanger by using the side member. A side member (A) consists of a core material and one or more layers of side member (A) applied onto one side or both sides thereof and being used in a clad member for a heat exchanger, wherein a plurality of periodic forms (B) of fine groove which become arcuate toward one direction of the side member (A) is formed on the surface of the side member (A). The periodic form (B) of fine groove extends up to the outer circumferential edge of the side member (A) with a radius of curvature of 800-1500 mm and has a period (D) of 1-8 mm in the above-mentioned direction of the side member (A) and surface roughness of the side member (A) in the above-mentioned direction of 1-15 μm 10-point average roughness (Rz).

    Abstract: A method of refining molten metal includes the steps of reduced-pressure-refining molten metal in a heated vessel, adding slag-forming agents into the refined molten metal while keeping the molten metal in the vessel, or after pouring the molten metal into another vessel, re-refining the molten metal by heating the molten metal with inert-gas plasma and while stirring the molten metal as occasion demands. Preferably, the refining apparatus includes two adjacent chambers, each chamber isolated from the surrounding atmosphere. The chambers can be connected with, or separated from, each other and each chamber is provided with an exhaust device. One of the chambers is provided with an induction heating refining furnace, and the other chamber is provided with inert gas plasma heater. The apparatus also includes a re-refining vessel which is transferable between the two chambers, and a material feeder for feeding slag-forming agents into the re-refining vessel.
