Abstract
จัดให้มีแผ่นเหล็กกล้าชุบเคลือบสังกะสีแบบอบอ่อนที่มีการยึดติดที่ดีกับเคลือบผิว และ วิธีการเพื่อการผลิตแผ่นเหล็กกล้าชุบเคลือบสังกะสีแบบอบอ่อนนั้น แผ่นเหล็กกล้าชุบเคลือบสังกะสีแบบอบอ่อนที่มีชั้นชุบเคลือบสังกะสีบนพื้นผิวของแผ่นนั้น ที่มีองค์ประกอบซึ่งมี C 0.10% ถึง 0.35% Si: 0.3% ถึง 3.0% Mn: 0.5% ถึง 3.0% P: 0.001% ถึง 0.10% Al: 0.01% ถึง 3.00% และ S: 0.200% หรือน้อยกว่า โดยมีพื้นฐานบนมวล ส่วนที่เหลือที่เป็น Fe และสิ่งเจือปนที่หลีกเลี่ยงไม่ได้ แผ่นเหล็กกล้ามีอัตราส่วน SiC/SiO2 มากกว่า 0.20 โดยที่ อัตราส่วน SiC/SiO2 เป็นอัตราส่วนของปริมาณ SiC ต่อปริมาณ SiO2 ณ ความลึก 1 ไมโครเมตร หรือ น้อยกว่า ในแผ่นเหล็กกล้าจากหน้าสัมผัสระหว่างแผ่นเหล็กกล้าและชั้นชุบเคลือบสังกะสี และ Fe ใน ชั้นชุบเคลือบสังกะสีนั้นประกอบอยู่ 8% ถึง 13% โดยมวล: Provide annealed galvanized steel sheet with good adhesion to the coating and a method for the manufacture of annealed galvanized steel sheet. Annealed galvanized steel sheet with a layer of zinc plating on the surface of the sheet. With elements containing C 0.10% to 0.35%, Si: 0.3% to 3.0%, Mn: 0.5% to 3.0%, P: 0.001% to 0.10%, Al: 0.01% to 3.00% and S: 0.200% or less with a basis. On mass Residual Fe and impurity are inevitable. Steel plates have a SiC / SiO2 ratio greater than 0.20, where the SiC / SiO2 ratio is the ratio of SiC content to SiO2 content at a depth of 1 micrometer or less in the steel sheet from the contact between the steel plate and the zinc-plated layer and Fe in the plating layer. The zinc coating is composed of 8% to 13% by mass:
