Abstract

본 발명은 온수탱크, 사일로, 개스랜지 삼발이 등 두꺼운 소재를 요구하는 법랑제품에 사용되는 열간압연강판의 제조방법에 관한 것으로, 내피쉬스케일성을 확보하기 위해 이용한 미세한 티타늄탄화물 대신 티타늄황화물을 이용하고 열간압연공정중 마무리압연온도를 낮게 하여 내피쉬스케일성을 확보하므로서, 각종 첨가물의 양을 감소시켜 법랑밀착성을 개선하고 내피쉬스케일성 또한 개선된 법랑용 열간압연 강판을 제조하는 방법을 제공하고자 하는데 그 목적이 있다.The present invention relates to a method for manufacturing hot rolled steel sheet used in enamel products requiring thick materials such as hot water tanks, silos, and gas trivets. By lowering the finishing rolling temperature during the hot rolling process to secure fish scale resistance, it is intended to provide a method of manufacturing hot rolled steel sheet for enamel by reducing the amount of various additives to improve enamel adhesion and improved fish scale resistance. The purpose is.

상기한 목적을 달성하기 위한 본 발명은 법랑용 열간압연 간판의 제조방법에 있어서, 중량%로, C:0.01%이하, Mn:0.1~0.4%, S:0.04~0.1%, Ti:0.05~0.15% 및 N:0.005% 이하를 포함하여 조성되고 (Ti/48-N/14)/(0.4S/32)가 1:3의 범위인 알루미늄킬드강을 열간압연하여 900℃이하의 온도에서 85% 이상의 압하율로 열간압연 마무리하고, 650℃이하의 온도에서 권취하는 것을 포함하여 이루어짐을 특징으로 하는 법랑특성이 우수한 열간압연 강판에 관한 것을 그 요지로 한다.The present invention for achieving the above object in the manufacturing method of the hot rolled sign for enamel, in weight%, C: 0.01% or less, Mn: 0.1 ~ 0.4%, S: 0.04 ~ 0.1%, Ti: 0.05 ~ 0.15 % And N: 0.005% or less (Ti / 48-N / 14) / (0.4S / 32) hot rolled aluminum-kilted steel with a range of 1: 3 The gist of the present invention relates to a hot rolled steel sheet having excellent enameling characteristics, including hot rolling finishing at the above reduction ratio and winding at a temperature of 650 ° C. or lower.
