Improve Fatigue

In order to improve fatigue life of wheel steel, LF-VD secondary-refining process is done with Al-deoxidation and slag of high basicity, high Al2O3 content and low oxidizing property. Inclusion content would be influenced by [Al]s, [Mg], [Ca] in molten steel. It is found that Al2O3 inclusions, which are the products of Al-deoxidation, would react with [Mg], [Ca] in molten steel to transform into CaO-MgO-Al2O3 complex inclusions, which is the key for the enhancement of fatigue performance for wheel steel.

Skew Rolling

The optimization of pass parameters is an important step in skew rolling design. In order to meet the demands of secondary refining process in continuous casting, on the basis of the practical experience of two-groove skew rolling for steel ball, and by means of the theory of two-groove skew rolling design ,the optimization of two-groove pass parameter for Φ21.6 mm Aluminum ball, a kind of additive in secondary refining process, is realized. The optimized pass parameters are used in the rolling die design, and the corresponding experiments indicate that the projects of optimized pass parameters are feasible, and the efficiency of two-groove skew rolling is twice as large as that of one-groove.

Improve Fatigue

In order to improve fatigue life of wheel steel, secondary-refining process is done with Al-deoxidation and slag of high basicity, high Al2O3 content and low oxidizing property. [M, [C content in molten steel would be influenced by slag composition. It is found that high basicity, high Al2O3 content and low oxidizing property is positive factor for proper [M, [C content in molten steel which is the key of inclusion transformation from Al2O3 to CaO-MgO-Al2O3 complex inclusion, contributing to the enhancement of fatigue performance for wheel steel.
