Converter tangential key mounting method and converter tangential key auxiliary mounting equipment

Abstract

The invention relates to a converter tangential key mounting method and converter tangential key auxiliary mounting equipment. The converter tangential key auxiliary mounting equipment comprises a base, wherein the base is provided with a heat preservation barrel and a fixing frame, the fixing frame is rotatably connected with a horizontal lifting arm and a pushing frame from top to bottom, the lower end of the lifting arm is connected with a lifting device, a horizontal telescopic device, a vertical telescopic device and a tangential key guide device are arranged on the pushing frame, the horizontal telescopic device is connected with the tangential key guiding device, the horizontal telescopic device provides driving force in the horizontal direction for one end of the tangential key guiding device, the lower end of the vertical telescopic device is detachably connected with a barrel cover of the heat preservation barrel, and the vertical telescopic device provides stroke driving force in the vertical direction for the barrel cover of the heat preservation barrel. According to the converter tangential key auxiliary mounting equipment, cold installation of a tangential key can becompleted under the condition that no person touches the tangential key, the structure is simple, operation is convenient, and the safety of operators can be better guaranteed.

Description

technical field [0001] The invention relates to the technical field of converter equipment, in particular to a converter tangential key installation method and converter tangential key auxiliary installation equipment. Background technique [0002] The tilting mechanism is the driving device to ensure the conversion of molten iron and tapping of the converter. The tilting mechanism and the trunnion of the supporting ring are connected by a tangential key and an interference fit is adopted. Generally speaking, the tilting mechanism is driven by a suspension type, and four first-stage gears are used to drive the internal second-stage large gear to rotate. The large gear and the support ring trunnion are connected by a tangential key, and the installation quality of the tangential key directly affects the tilting mechanism and the support. circle transmission efficiency. After the furnace body, support ring and tilting mechanism of the converter system are installed in place, ...

AI Technical Summary

Problems solved by technology

The tangential key can be pre-frozen to reduce the resistance between the tangential key and the keyway during installation, but because the temperature of liquid nitrogen is extremely low, usually -196°C, it is very easy to frostbite when touched manually, and there is a high safety hidden danger, and the manual adjustment of the interference is slow, the interference cannot be adjusted accurately, and it is easy to be lower than or exceed the design interference value. After the tangential key temperature rises, it cannot be adjusted in place, and it is difficult to disassemble and readjust, resulting in ear shaft or reducer gear for damage
