Supplement A7 B7 'V. Invention Θ (5) Amount% will damage the drawability t, so 0 • 0 0 1% by weight is the upper limit. The composition states the reasons for this limitation. 0 The steel sheet that is plated with alloyed molten zinc is immersed in a fresh molten bath. 9 The iron of the steel sheet can be diffused into the coating by heating the steel sheet to become Z η — F e alloy layer. The zinc steel plate has significantly improved corrosion resistance when compared with 9 chemical treatment and spot weldability. 6 The iron content in the coating can successfully achieve such a function. The performance of the ζ layer that causes the scale to peel off should not be continued. It must still be 9% by weight or more. -13-face AOp. When the iron content exceeds 1 2% by weight, even if the aluminum content in the plating layer is controlled to fall within the range described below. It develops into a hard and brittle Γ layer and hinders the press formability e. Therefore, the iron content in the plating layer must be 9 1 2% by weight or less. The aluminum content in the plating layer will affect the Zn η-F e formed during the alloying treatment. When the amount of aluminum in the alloy phase is less than 0 3% by weight, the development of the Γ layer tends to cause pulverization, and it is difficult to fully alloy it at 5% by weight. Therefore, the aluminum content in the coating is 0 • 3 1 5% by weight. 〇The pin in the plating layer has a bad effect on the corrosion resistance of 31L, so it is limited to 0 • 0 2% by weight or less. 〇The adhesion amount of the plating layer must be 2 5 g / ma when it is too thick / ητ *.

This paper size applies the Chinese National Standard (CNS) A4 specification (210X297 mm) ) -7-A6 B6 V. Description of the invention (1) The present invention relates to an alloyed molten zinc-plated steel sheet which is used in automotive body panels and the like, and has excellent press-workability and resistance to peeling of the coating. In recent years, automobile bodies have been required to strengthen rust prevention, and the strengthening strategy is directed to the surface-treated steel sheet of zinc.... Among them, especially the steel plate that scoops molten zinc has excellent economy. In addition, the heating layer is used to make the ore layer F e -Z. Η alloy (alloyed zinc plated steel plate) to improve Weldability and corrosion resistance after painting. '· ·' · · · · '. Because the steel plate of alloyed and melted (hereinafter referred to as GA) steel plate for automobile body outer panel is highly pressed for the purpose of improving decorativeness, The required material is one with high ductility (elongation E 1) and drawability (Rankford 値, r 値). As a countermeasure, the material of the steel plate is to reduce C, N, P, S, etc. in the steel, and a number of technologies have been developed together with the most suitable hot rolling, cold rolling and rolling engineering. Printed by the Consumer Standards Department of the Central Standards Bureau of the Ministry of Economic Affairs (please read the precautions on the back before filling out this page).... Fate. In addition, the characteristics required for the coating of GA steel plates are that it is not easy to occur during processing. Powdery peeling due to deformation of the steel sheet, and scaly peeling due to wear of the stamping die. If the above situation occurs, it will accumulate on the stamping die and cause stamping scars. Or it may become a problem of losing the original corrosion resistance of the plating. The coating of GA steel plate 'usually consists of low iron content, in the order of L, βι, and Γ of the three Zn—F e alloy phases'. The powdering system is considered to be due to the Γ phase, and the scale is peeled because the e is the cause. 〇However, in the case of materials with reduced C., N'P, and S, the use of ore-melted zinc to produce GA steel plates, although satisfactory ductility and r 値 materials can be obtained, but due to excessive alloying between the grains of the steel plate Acceleration, so as to increase Γ This paper size applies the Chinese National Standard (CNS) A4 specification (210x297 mm ^ '~~ A6 B6 V. Description of the invention (2) The amount of phase formation, and significantly reduces the chalking resistance. In order to To ensure powdering resistance, it is necessary to suppress the degree of alloying (Fe concentration) that does not form the Γ phase. However, this case, for example, is disclosed in Japanese Patent Application Laid-Open No. 2 -1 1 7 4 5 but only When the Γ phase is difficult to generate, and only the content of fe is limited,,,... The new problem of stripping ... The purpose of this invention is to reduce the C in steel, N, P, S, the obtained steel material steel plate is used as a material to obtain a powdered zinc alloy plated molten zinc plated resistance and scale peel resistance.

Also, • _, · · faint.-The reduction ratio of cold rolling is preferably 50% or more. -.v In terms of hot-dip galvanizing, first of all, the surface of the steel sheet is purified before annealing and reduction, which can be performed by degreasing, pickling or by burning. The steel quilt is then annealed and reduced. It is preferable to use a hydrogen 'atmosphere containing several to several tens of percent nitrogen. The dew point is preferably 0 ° C or lower. ’In order to ensure the material, the annealing reduction temperature must be higher than the recrystallization temperature. However, when considering the production efficiency, the temperature is higher than 78 ° C. The steel sheet after the annealing reduction is cooled in a reducing gas, and is then directly introduced into a molten galvanizing bath. The composition and temperature of the bath are determined as follows. Aluminum concentration in the bath: The present invention can control the amount of aluminum-iron alloy layer generated in the plating bath in order to achieve β i-phase alloying, and can ensure powder resistance and flaky peel resistance. Therefore, aluminum-iron alloys The layer amount is preferably the aluminum content in the alloy, and is preferably above 0.15 g / c rrf. The amount of aluminum in the bath must be above 0.13% by weight. In order to efficiently form an aluminum-iron alloy layer, It is preferably at least 145% by weight.
