Abstract
본 발명은 건자재용, 가전용 및 자동차용 강판으로 사용되는 합금화 용융아연 도금강판의 제조방법에 관한 것으로, 과합금화를 방지할 수 있을 뿐만 아니라 내파우더링성이 우수한 합금화 용융아연 열간압연 강판의 제조방법을 제공하고자 하는데 그 목적이 있다.The present invention relates to a method for producing an alloyed hot-dip galvanized steel sheet used as a steel sheet for building materials, home appliances, and automobiles. Its purpose is to provide it.
본 발명은 연속식 합금화 용융아연도금강판의 제조방법에 있어서, 0.08~0.16wt%의 Al을 함유하는 아연도금욕에서 후물재 열간압연강판을 용융도금한후, 연속적으로 합금화 가열대에서 열간압연 강판온도가 480-550℃가 되도록 가열하고, 이 온도에서 일정시간 유지한 다음, 공기와 물을 병행하여 고압분사하는 포그냉각방식에 의해 20~40℃/sec 의 냉각속도로 급냉하여 상부롤에서의 강판온도가 300℃이하가 되도록 합금화 열처리하여 내파우더링성이 우수한 합금화 용융아연 열간압연강판을 제조하는 방법을 그 요지로 한다.The present invention is a method for producing a continuous alloyed hot-dip galvanized steel sheet, the hot-rolled hot rolled steel sheet in a zinc plating bath containing 0.08 ~ 0.16wt% Al, and subsequently hot rolled steel sheet temperature in the alloy heating zone Is heated to 480-550 ° C, maintained at this temperature for a certain time, and then quenched at a cooling rate of 20 to 40 ° C / sec by a high-pressure spray of air and water at the same time. The method of manufacturing the alloyed hot-dip galvanized hot rolled steel sheet excellent in powdering resistance by carrying out alloying heat processing so that temperature may be 300 degrees C or less is made into the summary.
