Title: PRODUCTION OF Zn-Al-Si ALLOY PLATED STEEL SHEET EXCELLENT IN DESIGNING PROPERTY
Inventor: MATSUNAGA TAKAHIRO
IPC: C23C22/30
Filed: 1999-02-01
Abstract: PROBLEM TO BE SOLVED: To reduce the variation of spangle patterns by controlling the dew point of reducing atmospheric gas in an annealing furnace so as to be in a specified range. SOLUTION: A base metal steel sheet is subjected to Zn-Al-Si alloy plating by using continuous hot dip plating equipment provided with an inline annealing device. The steel sheet is first heated in an oxidizing furnace to remove oil contents adhered to the surface, which is cleaned, and after that, annealing is executed in a reducing atmosphere in an annealing furnace. At this time, the dew point of the gas in the annealing furnace is controlled to the range of -40 deg.C to +10 deg.C. As a result, the reactivity in the surface of the steel sheet subjected to the annealing is suitably suppressed, and its reaction with plating metal uniformly progresses to make uniform the size of spangles. The reducing atmosphere in the annealing furnace can be retained, generally, by jointly feeding gaseous dry H2 and gaseous dry N2, but, only by them, the dew point falls below -40 deg.C.  Therefore, water contents is preferably fed into the annealing furnace in the form of water and/or water vapor.

Title: Transfer device
Inventor: UTO YOSHITSUGU
IPC: B65H5/00
Filed: 1992-01-14
Abstract: PURPOSE:To provide a transfer device capable of transferring a work stably without producing scratches on the surface of the work even when a transfer speed is kept at a constant. CONSTITUTION:A transfer device 10 comprises a roller chain 20 in which a pair of link plates 21 are connected to each other by pins 24. Also transfer rollers 27 of permanent magnet larger in diameter of the link plate 21 are fitted closely onto the pins 21 on both sides of the link plate 21. For this, when a flat work of magnetic substance is attracted to the transfer device 10, the work W is made in contact only with the transfer roller 27. In addition, the transfer roller 27 produces an attractive force to the side of the link plate 21. Even if some difference in speed is generated between the transfer device 10 and the work W during transfer, it is absorbed due to rotational movement of the transfer roller. Thus the work W is attracted stably on the outer surface of the transfer roller 27 and transferred, and any trouble such as scratches on the surface of the work, etc., is not produced.
