Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hot-rolled strip steel production, and particularly relates to a splash-proof water baffle for a hot-rolled vertical roll. Background Technique
[0002] During the process of hot-rolling strip steel in a hot tandem mill, the temperature of the slab will rise to 1150 - 1280 °C after being heated in a heating furnace. During the rolling process by the rolling mill, while the thickness of the billet decreases, the width will expand in the width direction. To ensure the final width dimension accuracy, it is necessary to control the width dimension. Therefore, a vertical roll mill is configured in front of the rolling mill in the rough rolling area. At the same time, this rolling mill also contacts the high-temperature rolled piece and needs to be cooled. However, when cooling the vertical roll mill, the cooling water will splash onto the surface of the rolled piece at the same time, resulting in a large temperature drop at the edge of the rolled piece, which has a great impact on the subsequent setting of the rolling model parameters, causing a deviation between the setting calculation and the actual situation, affecting the stability of rolling. At the same time, the cross-sectional shape of the product appears abnormal, the intermediate billet has side bending, and the final product shows defects such as waviness, edge peeling, and edge black lines, greatly affecting the quality of the product.
