Abstract

The invention relates to a device and method for improving a finishing temperature of oriented silicon steel. The device comprises two hot mill rails, a steel template and a heat insulation plate are arranged on the hot mill rails, the steel template is arranged on the hot mill rails along the hot mill rails, the two sides of the steel template are bent downward to form side plates, the two hot mill rails are clamped between the two side plates, the two ends of the steel template are bent downward to form baffles, the two hot mill rails are clamped between the two baffles at the two ends of the steel template, the heat insulation plate is arranged on the steel template, and the heat insulation plate is fixed on the steel template through pressing strips. The method includes the step of enabling a forging stock to keep making contact with the heat insulation plate which is fixed on the hot mill rails. Through the device and method for improving the finishing temperature of the oriented silicon steel, the average finishing temperature of hot rolled plates is increased from 865 DEG C to 901 DEG C, the average magnetic induction intensity is increased from 1.865T to 1.895T, and the product percent of pass is increased from 52% to 93%.
