27Q130冷轧取向电工钢带的工业试制

Commercial Trial Production of Cold Rolled Oriented Electrical Steel Strip 27Q130

采用40tEBT+40tVOD+模铸+φ825开板坯+热轧,冷轧+退火工艺流程,试制了0.27mm*480mm110t27Q130冷轧取向电工钢带。通过合理成分设计,精心冶炼和轧制。试制的冷轧取向电工钢带成品的各项性能完全达到GB/T2521-1996中27Q130标准要求,部分达到27Q120标准要求。

Cold rolled oriented electrical steel strip was trial produced by adopting the process 40tEBT→40tVOD→mould casting→alab cogging by Ф825 blooming miil→hot roiling and cold rolling→annealing. Through the appropriate composition design and careful operation during melting and roiling, the properties of trial produced steel strip mentioned above could completely meet the requirements of 27Q130 in GB/T 2521 - 1996, parts of the properties could meet the requirements of 27Q120.
