Abstract: First in this paper a coil diameter calculation model is proposed.The model,working together with bar tracking and taking coil looseness factor into account in the diameter calculation,features in easy modification to accuracy of coil diameter calculation.To ensure the positioning accuracy of coil tail,a bar tail length calculation algorithm is presented as well that gives a more comprehensive description of the physical status of bar tail.As proposed in this paper,the height lowering model of cradle roll 1B can calculate accurately the reference of the roll height,and consequently achieve satisfactory control of roll height in practice.The key issues regarding to realization and application of the proposed models are discussed in detail in the last part of this paper.
