The Spread Model Research Of The Ultra-low-carbon Hot-rolled Steel

IF steel as a basis for development by almost all kinds of ultra-low carbon steel plate to meet the vehicle by the various performance requirements, the thin sheet of ultra-low carbon steel demand is increasing and requiring their increasingly high-quality. As ultra-low carbon steel is unique, in the rolling production easily and leads to all kinds of defects, ultra-low carbon steel edge of Alice is a common skin surface defects. Such defects in the randomness of larger, more difficult to control, seriously impact on the metal to finish product yield and quality.From ultra-low carbon steel metal plastic deformation on the principle of ultra-low-carbon steel for the spread of the study on the hot-rolled carbon steel, ultra-low-flow law of the metal, We establish a more suitable for ultra-low carbon steel model of the spread .In the hope of the ultra-low carbon steel, "Alice Paper," the study and control lay a solid foundation.Papers stem from the flow of hot metal at the start, the spread on the type, variety and influence factors for the spread,making ultra-low carbon steel model of choice of the right variables. Through the spread modeling methods of research and spread of various models of the basic analysis, the model structure and spread modeling regression analysis,in the contrast of the scene, the model calculated and measured very well, the accuracy of models can meet demand . According to the results of the model of spread, the workpiece edge of the uneven deformation, edger lateral deformation and "dog bone" spread changes were analyzed. Papers still analysis the experiment of the spread under the conditions of the lab, according to the experimental data of the spread,We can establish a slide-show, drum-shaped spread and the over-spread model and analysis their relationship in a certain amount.
