摘要:
In a furnace (2) having an inlet (8a, 8b, 8c) and an outlet (9a, 9b, 9c), a plurality of conveying components (a, b, c) for conveying materials to be heated from the inlet toward the outlet (8a to 9a, 8b to 9b 8c to 9c) are provided in parallel. A plurality of the materials are continuously loaded on the conveying components at the inlet of the furnace, subjected to heat treatment during the conveying process performed by the conveying components in the furnace, and successively reach the outlet. In this process, the conveying components are driven at conveying speeds which are different from each other. Among a plurality of the materials to be heated, these materials which are required to be heated for a long time are loaded on conveying components which are driven at low speed. As a result, they are conveyed and heated in the furnace for a long time. On the other hand, the materials which are only required to be heated for a short time are loaded on the conveying components driven at a high speed and consequently, they are conveyed and heated in the furnace for a short time.
摘要:
Method and apparatus for conveying strip materials in a floated manner whereby a strip (18) is allowed to pass between a pair of chambers (20'20, 32/32, 38/38) vertically spaced apart from each other and provided with a plurality of jets or blowoff openings at one surface thereof so that jets of gases are blown therefrom against the strip so as to float the strip. Ifthe strip to be conveyed is of a smaller width, then the width of the gas stream blown from the lower chamber is correspondingly reduced so that a saving of energy required for blowing the gases maybe achieved.
