| 摘 要： | 2.0~2.8mm的50W470无取向硅钢(%:≤0.005C,1.45~1.65Si,0.2~0.4Al)经20辊森吉米尔可逆式轧机5道次轧制成0.5mm的轧卷,各道次压下率15%~35%,总压下率为75%~80%。试验结果表明,经5道次轧制后钢中晶粒全部细纤维化,抗拉强度由坯料的480~560MPa增加至885~905MPa,伸长率δ5由25%~28%降至0.7%~0.8%。经X射线衍射谱线型分析表明,经5道次轧制后的无取向硅钢50W470中存在残余内应力(第2类内应力)是形成冲片椭圆度的重要原因。

| Abstract: | The 0.5 mm non-orientation silicon steel 50W470 (≤0.005C,1.45～1.65Si,0.2~0.4Al)coil was rolled by twenty- high Sendzimir mill from 2.0~2.8 mm plate with pass reduction 15%～35% and total reduction 75%~80%.The test results showed that with 5 pass rolling the grains in steel were all fibration,the tensile strength increased to 885~905 MPa from 480~560 MPa rolling billet, clongation s decreased to 0.79%~0.8% from 25%～28%.And the X-ray diffraction spectrum analysis showed that with 5 pass rolling the residual stress(secondary stress)existed in non-orientation silicon steel 50W470 which was main cause to form elliptical type stamping. |
