Tilting mechanism is to achieve one of the main steelmaking production equipment, which is characterized by a large dump Moment, gear ratio, starting and braking frequently and withstanding greater dynamic load. Converter tilting mechanism works in harsh working environments, more slag dust and high temperatures. Thus their reliability and longevity for the safe operation of the equipment throughout the converter has a very significant impact. Adaptation to obtain a low rotational speed of the drive requires a large reduction ratio. Great weight converter furnace, plus loading weight, etc., the entire weight of the part to be tilting up hundreds of tons or thousands of tons. BOF furnace steel smelting a time, usually only four minutes later. Converter tilting mechanical work belongs to "start working system." In addition to the basic institutions to withstand static loads, but also to withstand dynamic loads due to start, braking caused. This dynamic load in the mouth skimming operation, more than twice its value even to static loads. Kai, the amount of braking complex, dynamic cut withstand greater load. As the steelmaking process low, heavy and harsh working conditions, coupled with the start, brake frequently, especially on a different way to start the motor on the dynamic behavior of the converter. With the converter tilting BOF steelmaking machinery popularization and development also continues to develop and improve, there have been various types of tilting the device. With torsion bar stopper buffer full hanging tilting mechanical, diagonally arranged into four main transmission system of a reducer drive one at the center of the second gear, so as to drive the rotary converter work performed. This paper converter tilting mechanism gives a brief introduction. Introduction tilting mechanism structure, design principles, the basic design parameters, as well as several forms of structure and configuration of the drive tilting mechanism and the transmission format.
