Research Of Continuous Curve And More Excellent Straightening Turn On R9300 Slab Castingmachine In An Steel

The bent straightening keeps the key technique that the technique is the continuous casting steel realm. Straightening means that the bendt cast is turned to straight cast under external moment which aroused the plastic deformation.The adoption of the multi-point straightening that makes the continuous casting machine carry out the tape liquid core straightening, improved casting speed. But multi-point straightening arouse bigger strain catastrophe in each straightening roll. Under the sistuation that the higher-pull soon, for the sake of assurance tape liquid core cast straightening the strain rate and the strain speed control generate by two phase zones is in allow the value range, Taking idle speed teeming as the simple point straightening and multi-point straightening of the back ground is hard to have already satisfied to produce a demand. Continuously the straightening technique was good to resolve this problem, The strain of the cast changes continuously in the whole straightening zone, meeting an emergency speed to lower obviously. The critical strain that makes the cast generate a crack thus can raise, to reduce or avoid bug availably. So, go on the research continuous straightening theory has very important and realistic meaning.This text introduced the type of familiar few straightening localization, Analyzed the CONCAST curve bug, Pointed out to have the advantage of the continuous straightening curve of two straightening zones and in physically the application existent question, and improved the curve, completed the account for An steel's 2# casting machine alteration.
