A device for discharging residual iron from a skimmer

Abstract

The invention discloses a device for discharging residual iron of a slag skimmer. The device comprises a pneumatic rock drill, a supporting cross rod, a supporting oblique rod, a pulley and a riggingturnbuckle, wherein the pulley and the rigging turnbuckle are connected with the supporting cross rod. A first fixed hanging ring and a fixed sleeve are fixed to the outer wall of the slag skimmer, the first fixed hanging ring is located on the upper side of the fixed sleeve, one end of the supporting cross rod is movably inserted into the fixed sleeve, and a second fixed hanging ring is fixedly connected with the other end of the supporting cross rod; and the supporting cross rod and the outer wall of the slag skimmer are perpendicularly arranged, the two ends of the supporting oblique rod are connected to the first fixed hanging ring and the second fixed hanging ring in a hung mode through hooks correspondingly, and a certain included angle is formed between the supporting cross rod andthe supporting oblique rod. According to the device, the efficiency that a residual iron hole is perforated can be improved.

Description

technical field [0001] The present application relates to the technical field of iron and steel blast furnace pouring, in particular to a device for discharging residual iron from a skimmer. Background technique [0002] The blast furnace iron hook is the pouring type iron trench of the blast furnace. After a certain period of use, the blast furnace iron trench needs to be dismantled and re-cast. During the service life of the blast furnace iron trench, there is always residual iron (that is, residual high temperature molten iron), before dismantling, the residual iron in the skimmer needs to be discharged for subsequent dismantling work. [0003] At the bottom of the skimmer, there is a residual iron eye specially for discharging high-temperature molten iron. Since the wall thickness of the skimmer is generally relatively thick, while the wall thickness of the residual iron eye is relatively thin. Iron released. At present, when digging through the residual iron eye, the ...

Problems solved by technology

[0004] However, because the pneumatic rock drill is heavy and the residual iron eye is a straight hole, not only is the worker holding the pneumatic rock drill, but it is difficult to keep the drill bit of the pneumatic rock drill and the residual iron eye always coincident, and the drilling deviation may occur, and the worker cannot continue for a long time. The operation will prolong the working time, thereby affecting the drilling progress and greatly reducing work efficiency; in addition, when the residual iron eye is drilled through, the residual high-temperature molten iron will flow out of the residual iron eye, which is very likely to burn the workers and cause unnecessary damage. safe question
