Abstract: PURPOSE: A method of manufacturing a low-carbon cold-rolled steel plate is provided to enhance processability by having a small anisotropy coefficient and large elongation ratio and average plastic strain. CONSTITUTION: Steel consists of, by weight %: 0.015-0.050% of C, not more than 0.010% of Mn, 0.002-0.030% of Zr, not more than 0.020% of P, not more than 0.015% of S, not more than 0.015% of Si, not more than 0.04% of Al, not more than 0.004% of N, Fe and incidental impurities. The steel is heated at a temperature of 1050-1300°C and hot-rolled at a temperature of 660-750°C. Then, the steel is cold-rolled to 65-90% and continuously annealed at a temperature of 750-870°C at a speed of 20-100°C/s and at a temperature of 350-500°C. Finally, the steel is rolled to 1.0-2.0% to manufacture a low-carbon cold-rolled steel plate with a small anisotropy coefficient of plastic strain.

Abstract: 실내에 발생하는 유해가스를 실외로 배출하고, 실내로 복귀하지 않는 습기교환용 소자를 제공하는 것을 목적으로 한다. 분자 내에 화학 결합한 전리기를 가진 스틸렌계 이온교환수지를 습기흡착제로서 부착한 시트를 다수의 작은 구멍을 가지도록 적층성형한 것이다. 이것에 의해, 실내에서 발생하는 유해가스를 실내로 복귀시키지 않고 외부로 배출하면서 습기의 교환을 실시할 수 있다.
