In this paper, continuous casting process for high-speed locomotive brake beam steel have been introduced, factors affecting the quality of rectangle bloom was also discussed.

Taking L-C combined brake beam as an example,this paper proposes the control law for the optimum design of brake beam body under the equivalent life principle and suggests that overload on the end of the strut is the main reason of such failure by analyzing the failure modes of the brake beams on freight cars.

The application of "turn-angle" survey in the fabrication of steel box girders will not affect the straight transport of box girders when removed from the fixtures, instead, to make the layout of general assembly site more compact and reasonable, thus meet the quality and progress requirements for steel box girder fabrication and reach the aim of low cost and high efficiency.
