Abstract
แผ่นเหล็กกล้ารีดร้อน ซึ่งหนา 3-20 มม. และผสมด้วย ปริมาณจำเพาะของ C, Si, Mn, P, S, Al และ N โดยสมุดประกอบด้วย เหล็ก และสารปนเปื้อนที่ไม่สามารถเลี่ยงได้ แผ่นเหล็กกล้า รีดร้อนผสมด้วย ปริมาณจำเพาะของ ตัวละลายของแข็ง N และปริมาณของ C และ N จะได้ตาม ความสัมพันธ์ 10C+N (สูตร) 3.0 แผ่นเหล็กกล้ารีดร้อนนี้ผสมด้วย เบนนิติก เฟอไรต์ และเพิร์ลไลต์ ตามลำดับ ในอัตราส่วนพื้นที่ 5% หรือมากกว่า และในอัตราส่วนพื้นที่น้อยกว่า 20% เทียบกับ โครงสร้างทั้งหมด โดยสมดุลประกอบด้วย เฟอไรต์รูปหลายเหลี่ยม ขนาดเกรนผลึกเฉลี่ยของ เบนนิติก เฟอไรต์เป็น 3-50 (สูตร)m Hot-rolled steel sheets, which are 3-20 mm thick and are mixed with specific quantities of C, Si, Mn, P, S, Al and N, the book contains iron and impervious contaminants. Steel plate Hot rolled mixed with Specific quantity of The solid solvent N and the amount of C and N are obtained according to the correlation 10C + N (formula) 3.0, this hot rolled steel plate is mixed with benzene, ferrite and pearlite, respectively, in a 5% area ratio or More and in a ratio of less than 20% of the total structure By balance consisting of Polygon ferrite The average crystalline grain size of the benign ferrite is 3-50 (formula) m.
