Using the effective matrix methods of flatness and profile control synthetically, the flatness and profile in- tegration control scheme for tandem cold mills is built in order to increase flatness and profile control precision of tan- dem cold mills. Corresponding control strategies are adopted for various control objectives of different stands and the coordination control strategies of various stands are given, which makes the on-line flatness control cooperate with on-line profile control and implements the parallel control of different stands. According to the measured flatness and profile data of some 1550 mm tandem cold mills, the control scheme is verified and the result indicates that the scheme has high flatness and profile control precision with steady and reliable control process. A new way and method is supplied for researching shade control of tandem cold mills.

In order to lucubrate the rolling characteristic of the two stands reversible cold rolling mill and establish the tension and thickness control strategy, the steady-state characteristic simulating program was established using the steady-state continuous rolling theory. The influences of each factor on exit thickness under different tension control methods were analyzed. The results show that, the influence of the entry stand gap on exit thickness is significant and it changes little with different tension control methods. As a result, the entry stand gap can be used as the main control method of exit thickness, whereas rolling speed of any stand and roll gap of the exit stand can be used to adjust the inter-stand tension. The results are beneficial for thickness and tension control of the two stands reversible cold rolling mill.

Reducing the core loss of amorphous cores for distribution transformers

Progress in Natural Science:Materials International 2012年第3期22卷 244-249页

作者： Deren Li, Liang Zhang, Guangmin Li, Zhichao Lu, Shaoxiong Zhou china iron & steel Research Institute group, Advanced Technology and Materials Co., ltd., No. 76, Xueyuan Nan Rd., Haidian District, Beijing 100081, china china iron & steel Research Institute group Advanced Technology and Materials Co. Ltd. No. 76 Xueyuan Nan Rd. Haidian District Beijing 100081 China

Although amorphous alloy ribbons have lower core loss, serious loss deterioration occurs in amorphous cores constructed from amorphous alloy ribbon for distribution transformer. In the present study, the loss deterioration mechanism and influencing factors of amorphous cores for distribution transformers were investigated. The influence of distributed gaps on core loss of transformer core was calculated by simulation software and validated by experiments. The boron fluctuation of amorphous alloy ribbons affects the annealing temperature of amorphous transformer cores. A superior core annealing technique with annealing parameters was developed, and appreciable decrease in core loss was obtained.
