Abstract


The tilting device is a the converter steelmaking mechanical equipment, used for the furnace smooth tilting and accurate to locate, and the completion of the converter against the hot metal, tapping, feeding, furnace repair a series of process operation. The tilting device operating load is characterized by the low-speed, heavy-duty, positive frequent Kai brake strong impact, bear a greater dynamic load, and poor working conditions. Therefore, how to improve the reliability and ease of use of the device, industry research has been an important issue. In this paper, geometric modeling, numerical calculation methods of computer analysis and field trials, the actual work situation, combined converter engages the drive train of the tilting mechanism of the complex four-point analysis to identify the shortcomings of the traditional tilting device structure structure, on the converter tilting movable means of the performed analysis and optimization, explore driveline gear temperature and drive heat efficiency analysis calculation method, analyzing the tilting mechanism occurs swing the reasons, calculated turn poured dynamic moment curve, designed to improve the overall performance of the tilting apparatus, to ensure that its tilting Activity operational reliability. Specific studies are as follows: (1) the application of Autocad and Pro / E software converter tilting device geometry modeling and structural analysis. The analysis of the design principles of the converter tilting mechanism, the basic design parameters, several basic form of the structure and configuration as well as the driving of the tilting mechanism and the transmission form. (2) a reasonable allocation converter tilting the device at all levels of gear ratio range, the establishment of the optimum design model of the tilting device. Complex tilting mechanism train structure, design parameters, their mathematical model of optimization to solve the problem, the preparation of the Matlab program to solve. (3) Pour braking torque converter tilting mechanism design parameters and calculate its purpose is to determine the rated pour Moment value as the basis tilting mechanism design. BOF empty furnace weight and center of gravity position, different angles when the furnace liquid center of gravity, and converter tilting Moment and rotation inertia amount calculated analysis of the factors converter tilting power moment curve changes in the law and its impact, and to explore the converter tilting bodies of torsional vibration suppression measures. (4) Integral temperature method principle, the gear tooth surface scuffing load capacity; study the agitation lubricating oil heat generated due to the heat generated by the friction, the heat generated by the bearing friction and gear reducer inside the gear meshing process. The preparation of the corresponding computer analysis software. (5) analysis of Hangzhou Iron and Steel # 1 BOF rotation, tilting device trunnion center was a circular trajectory generation reason. Checking Converter Ring trunnion rotary swing reducer deflection, torsion bar stopper the device clearance values, in order to use the converter tilting the device to provide practical reference.
