Problems solved by technology

[0003] The commonly used method now is: after the residual iron is put in, use a simple steel rod welded with a disc at the front end to carry out the plugging operation. All manual operations are time-consuming and laborious. The operation is difficult and takes a long time. Rugged, people are prone to collisions, trips and other safety accidents

Abstract

The invention discloses a residual iron hole plugging device which comprises a body frame, a mud making barrel, a pressure keeping air cylinder and a mud making air cylinder. The mud making barrel isarranged in the body frame and can move front and back relative to the body frame. A mud making disc is arranged in the mud making barrel, the mud making disc is fixed to the end part of a piston rodof the mud making air cylinder, a cylinder body of the mud making air cylinder is fixed in the body frame, and the mud making air cylinder can drive the mud making disc to move relative to the mud making barrel; and a cylinder body of the pressure keeping air cylinder is fixedly connected to the body frame, a piston rod of the pressure keeping air cylinder is fixedly connected to the mud making barrel, and the pressure keeping air cylinder can drive the mud making barrel to move front and back relative to the body frame. The residual iron hole plugging device disclosed by the invention is simple to operate, saves time and reduces the labor intensity and the operational safety risk.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to a plugging device for residual iron eyes. Background technique [0002] Modern large-scale blast furnaces all adopt the iron storage type main ditch with a slope of about 1% to 3%, and 50t to 100t of molten iron is stored in the ditch. During tapping operation, the inner side of the main ditch system is soaked and washed by molten iron and slag at a temperature as high as 1450-1550°C, so the refractory material and castable layer of the main ditch are strongly eroded and melted, and the main ditch must be repaired in real time according to the erosion situation At this time, it is necessary to release the molten iron accumulated in the ditch, and it is necessary to open the residual iron eye. Iron Eye does not have dedicated automated machinery. [0003] The commonly used method now is: after the residual iron is put in, use a simple steel rod welded with a disc ...
