摘要

采用三维高斯计在实验室测定了自行研制的板坯连铸用行波搅拌器的磁场变化规律。结果表明

在给定输入频率与两相对磁极间距下研制的双侧搅拌器的磁感应强度随输入电流的增加呈线性增加

为了使搅拌器中心的磁感应强度达到600×10

-4

输入电流约为600 A。在(180~220)mm×(900~1 630)mm板坯连铸机单侧二冷电磁搅拌现场测试结果表明

如采用所研制的双侧直线型电磁搅拌器时

输入电流只要445~595 A

中心磁场的磁感应强度即可达(450~600)×10

有效地提高了搅拌效率。

Abstract

The evolution law of magnetic induction of traveling wave stirer developed for the concasting slab was determined by using 3- dimensional Gauss meter in laboratory. The test results showed that the magnetic induction of developed two-side stirrer linearly increased with increasing input current at given input frequency and distance between relative magnetie pale pairs

and as the input curent was ~600 A

the magnetic induction at center of stirer was up to 600×10

-4

T. The measured results using single side secondary cooling magnetic stiring in situ of(180～220)mmx(900～1630)mm slab concaster obtained that as input curent only is 445～595 A developed two side stirer the magnetic induction at center magnetic field shall be up to(450~600)×10

-4

it is available to increase stiring eficiency
