Cause and Control of Web Plate Cracks on Special-shaped Billets The Influence and Control of Secondary Cooling of Special-shaped Billets on Web Plate Cracks
Surface cracks on the web plate of section steel are one of the main defects.In order to improve the rolling yield,the mechanism of crack generation was studied.By optimizing the cooling system and improving the lubrication method of the crystallizer foot rolls,the cracks on the cast billet were significantly reduced,and the qualified rate of the surface quality of the H-section steel web plate was significantly increased.
