Abstract
DC60(11/12/56) วัสดุชั้นนอกโรลล์สำหรับรีดร้อนและโรลล์เชิงซ้อนสำหรับรีดร้อนที่มีความต้านทานต่อการสึก หรอ,ความต้านทานต่อการเปลี่ยนอุณหภูมิฉับพลันและความต้านทานต่อผิวเสื่อมที่ล้วนแต่ดีเลิศ กำหนดให้องค์ประกอบของวัสดุชั้นนอกเป็นองค์ประกอบที่มี(mass%)C:2.43.5%,Si: 1.22.4%,Mn:0.22.0%,Cr:0.82.1%,Mo:0.31.1%,Ni:3.06.0%,V:1.02.2%,Nb: 0.10.5%,REM:0.00050.1%,AI:0.0030.05%รวมทั้งปริมาณที่มีC,Cr,V,Nb,REM,AI เป็นไปตามสมการCr+0.2น้อยกว่าหรือเท่ากับC(0.24xV+0.13xNb)น้อยกว่าหรือเท่ากับ3.0,0.01น้อยกว่าหรือเท่ากับREM/AIน้อยกว่าหรือเท่ากับ3.2(ณที่นี้C,Cr, V,Nb,REM,AI:ปริมาณที่มี(mass%)ของแต่ละธาตุ)และส่วนที่เหลือเกิดจากFeและสิ่งเจือปนที่ เลี่ยงไม่ได้ รูปที่เลือกใช้รูปที่1 DC60(11/12/13) Hot rolling roll outer material and hot rolling complex roll with wear resistance. Or, resistance to sudden temperature changes and surface deterioration are all excellent. Set the composition of the outer material to be the composition having(mass%)C:2.43.5%,Si: 1.22.4%,Mn:0.22.0%,Cr:0.82.1%,Mo:0.31.1%, Ni:3.06.0%,V:1.02.2%,Nb: 0.10.5%,REM:0.00050.1%,AI:0.0030.05% including content containing C,Cr,V,Nb,REM,AI According to the equation Cr+0.2 less than or equal to C(0.24xV+0.13xNb) less than or equal to 3.0,0.01 less than or equal to REM/AI less than or equal to 3.2 (here C,Cr, V,Nb ,REM,AI: the amount contained (mass%) of each element) and the rest comes from Fe and unavoidable impurities. The selected figure is Figure 1.
