Abstract
본 발명은 가전용 및 자동차용 강판등으로 사용되는 합금화 용융아연 도금강판의 제조방법에 관한 것으로써, 도금층내의 철의 함량이 8-12중량%인 합금와 아연도금강판의 제조에 있어서 도금욕내의 납의 첨가량및 합금화 열처리후의 냉각속도를 조절함으로써, 가공변형에 대한 도금층의 파우더링성을 향상시킬 수 있는 용융아연 합금화 도금강판의 제조방법을 제공하고자 하는데, 그 목적이 있다.The present invention relates to a method for producing an alloyed hot-dip galvanized steel sheet used in steel sheets for home appliances and automobiles, and the like in the production of alloys of 8-12% by weight of iron in the plating layer and the lead in the plating bath. It is an object of the present invention to provide a method for producing a hot-dip galvanized galvanized steel sheet which can improve the powdering property of a plating layer against work deformation by controlling the amount of addition and the cooling rate after the heat treatment of alloying.
본 발명은 아연도금층의 합금화 열처리에 의하여 도금층내의 철함유량이 중량비로 8-12% 범위인 용융아연 합금화 도금강판을 제조하는데 있어서 도금욕내의 납의 합유량이 중량비로 0.15% 이하가 되고 합금화 열처리후 도금강판을 초당 18℃ 이상으로 냉각하여 도금층 가공성이 우수한 용융아연 합금화 도금강판을 제조하는 방법을 그 요지로한다.In the present invention, in the manufacture of hot-dip galvanized galvanized steel sheet in which the iron content in the plating layer is in the range of 8-12% by weight by alloying heat treatment of the galvanized layer, the alloying amount of lead in the plating bath is 0.15% or less by weight ratio, and the coated steel sheet after alloy heat treatment. The method of manufacturing the hot-dip galvanized galvanized steel plate excellent in plating layer workability by cooling to more than 18 degreeC per second is made into the summary.
