Abstract
เพื่อจัดให้มีวิธีการเคลือบโลหะแบบจุ่มร้อนต่อเนื่องที่ใช้หัวฉีดแก๊สแบบกวาดเพื่อควบคุม น้ำหนักเคลือบผิว และกันการบังเกิดของข้อบกพร่องของพื้นผิวเคลือบผิวเพื่อให้สามารถผลิตแถบ เหล็กกล้าเคลือบโลหะแบบจุ่มร้อนคุณภาพสูงได้อย่างเสถียร ณ ต้นทุนต่ำ ได้จัดให้มีแถบเหล็กกล้า และเครื่องอุปกรณ์การเคลือบโลหะแบบจุ่มร้อนต่อเนื่องอีกด้วย วิธีการเคลือบโลหะแบบจุ่มร้อนต่อเนื่องรวมถึงการจุ่มจมแถบเหล็กกล้าลงในบาธโลหะ หลอมเหลวอย่างต่อเนื่อง และการเป่าแก๊สจากหัวฉีดแก๊สแบบกวาดลงบนแถบเหล็กกล้าในทันทีหลัง การนำแถบเหล็กกล้าออกมาจากบาธโลหะหลอมเหลวเพื่อควบคุมน้ำหนักเคลือบผิว ซึ่งในนั้น อุณหภูมิ T ของแก๊สสำหรับกวาดที่จะได้รับการฉีดจากหัวฉีดแก๊สแบบกวาดได้รับการควบคุมโดยมี พื้นฐานบนค่า D/B ซึ่งเป็นอัตราส่วนของระยะทาง D ระหว่างปลายสุดของหัวฉีดแก๊สแบบกวาดและ แถบเหล็กกล้าต่อช่องว่าง B ของหัวฉีดแก๊สแบบกวาด To provide a continuous hot dip metal coating method that uses a sweep gas nozzle to control Coating weight And prevent the occurrence of defects of the coating surface so that strips can be produced High-quality hot-dip coated steel has been stable at low cost. And continuous hot-dip metal coating equipment as well The method of continuous hot-dip coating includes submerging of steel strips into a metal bath. Constantly smelt And blowing gas from a sweeping nozzle onto a steel strip immediately after The steel strip is removed from the molten metal bath to control the coating weight, in which the temperature T of the sweeping gas to be injected from the sweeping gas nozzle is regulated on the basis of D / B, which is The ratio of distance D between the ends of the sweeping gas nozzle and Steel bar to gap B of the sweep gas nozzle.
