A conventional tin plating reflow apparatus has a structure as shown in FIG. 2, for example. That is, it consists of a reflow furnace (in which a gas burner (1) is arranged) and a water tank (3) for cooling.
Guide roll (5a) that guides the tin-plated strip (4)
, (5b) are arranged above the reflow oven inlet and in the water tank (3). The electro-tin plated strip (4) is guided into the reflow oven (2) by guide rolls (5a), heated above the melting temperature of tin, and transferred to the guide roll (5b) in the water tank (3). The speed at which the zero strip is guided and rapidly cooled in the water tank (3) is often determined by the electroplating conditions.
The reflow oven (2) has an exhaust duct (6) and an exhaust blower.
(7) is installed. Inside the reflow oven (2) is a burner panel (8a) to which a gas burner (1) is attached.

る。Further, since a water seal jacket reaching the water surface is provided between the tin-plated material outlet at the lower end of the reflow oven and the water surface of the water tank, it is possible to prevent air from flowing in from the lower end of the reflow oven. On the other hand, the internal pressure is measured by the furnace internal pressure measurement means attached to the reflow oven, and the exhaust air volume is adjusted by the exhaust air volume adjustment means so that the furnace internal pressure does not become a negative pressure with respect to the atmospheric pressure. It is possible to prevent it from flowing into the furnace.

A cylindrical water seal jacket (12) made of an iron plate is provided that reaches the water surface (15) of 3) to prevent air from entering from the lower end of the reflow oven (2). In addition, in order to ensure that the tip of the jacket (12) remains submerged in water, an overflow pipe (16) and a water supply pipe (17) are attached to the water tank (3) to ensure that the water surface (15) remains submerged. maintains a constant position. A manometer (14) is attached to the reflow oven (2), and the internal pressure of the reflow oven (2) is made negative by operating the butterfly valve (13) for adjusting the exhaust air volume installed in the exhaust duct (6). The amount of exhaust gas suction can be adjusted to prevent this. A gas mixer (9) is installed at the gas supply port (18) of the gas burner (1).
