Rotary type uncovering machine and rotary type uncovering method for blast furnace iron runner

Abstract

The invention provides a rotary type uncovering machine and a rotary type uncovering method for a blast furnace iron runner. The rotary type uncovering machine and the rotary type uncovering method are used for uncovering and sealing a runner cover on the blast furnace iron runner. The uncovering machine comprises a rotating mechanism, a lifting mechanism, a runner cover swing mechanism and a lifting socket, wherein a slewing bearing is arranged on the rotating mechanism; the slewing bearing comprises a revolving platform; the lifting mechanism is fixed on the revolving platform; a supporting seat, a lifting arm and a lifting driving device are arranged on the lifting mechanism; a swing driving device is arranged on the runner cover swing mechanism; a hoisting hook is fixed below the swing driving device; a transverse pole of the lifting socket is attached to the hoisting hook. The rotary type uncovering machine provided by the invention can effectively lower the total height of the uncovering machine and is preferably suitable for complex environments of a casting house; the rotating mechanism has the advantages that the structure is simple, the installation is easy, the working is safe, and the maintenance is convenient.

Description

Technical field [0001] The invention relates to an uncovering device, in particular to a rotary uncovering machine specially configured for blast furnaces in the metallurgical industry and a rotating uncovering method for a blast furnace iron trough. Background technique [0002] Large and medium-sized blast furnaces generally use iron storage trenches. After the tap is opened during the tapping process, the molten iron splashes and emits a large amount of smoke and dust. This not only causes great hidden dangers to the safety of the operators in front of the furnace, but also seriously pollutes the environment. In order to adapt to the large-scale and environmentally friendly production of blast furnaces and to improve the operating environment in front of the furnace, modern blast furnace production requires that all the iron ditch be sealed with a trench cover during tapping. The ditch cover on the iron ditch of the blast furnace is the basic requirement for controlling smoke ...

AI Technical Summary

Problems solved by technology

[0003] Near the blast furnace taphole, multiple equipment such as taphole machines, mud guns, and capping machines are required to be placed in a concentrated manner, making the space near the taphole narrow; at the same time, the capping machine is installed near the taphole of the casthouse Above is the tuyere platform, the height of the tuyere platform is low, and the height of the tuyere platform in the casthouse is low, which limits the height of each equipment and the installation and use of general uncapping machines

In addition, the traditional walking or rotating cover removing machine needs to be equipped with a walking mechanism to ensure that the lifting hook can approach the ditch cover anti-stop hanging seat along the direction of the vertical iron ditch to complete the lifting task, which inevitably increases the The space occupied by the device and the complexity of the device

As mentioned above, most of the existing uncapping machines are complex in structure and need to occupy a large space, and are prone to various failures in the high-temperature environment of the casthouse, and cannot guarantee timely uncapping and capping, causing serious damage to the safe production of the blast furnace. great danger
