Abstract

Aiming at the problem that the pulling force of the brick stripping machine in the prior art is too small and the brick stripping effect is not good, the present invention provides a manual brick stripping machine, which includes a hook device for inserting into the brick hole of the oxygen lance, a force applying device and It is used to support the bracket on the surrounding bricks around the oxygen lance brick during disassembly; the draw hook device includes a draw hook mechanism for going deep into the metallurgical furnace from the brick hole and a larger diameter for the draw hook mechanism to enter the metallurgical furnace Thereby, the retractor expansion mechanism stuck inside the oxygen lance brick; wherein, the retractor expansion mechanism can maintain the expansion state of the retractor mechanism after the diameter of the retractor mechanism enters the metallurgical furnace becomes larger; its technical solution lies in: Connected with the draw hook mechanism, move the draw hook mechanism in the expansion state axially through mechanical transmission, so as to move the oxygen lance brick outward and pull the oxygen lance brick out of the surrounding brick. The invention has the advantages of simple structure, compact structure, portability and quick and reliable action.

Description

technical field [0001] The invention relates to auxiliary removal equipment for oxygen lance bricks in metallurgical furnaces, in particular to a manual brick removal machine with simple structure, convenient operation and saving manpower and material resources. Background technique [0002] In the converter bottom blowing smelting process, it is necessary to blow gas into the smelting furnace through the oxygen lance, and the oxygen lance is fixed by the refractory material wall brick (oxygen lance brick) with holes built in the furnace wall. Both the use of medium oxygen lance and oxygen lance bricks will cause burning loss and shorten, and finally fail. Therefore, the oxygen lance and the oxygen lance brick must be replaced at regular intervals. [0003] While replacing the oxygen lance, it is also necessary to remove and replace the oxygen lance bricks that fix the oxygen lance and surrounding bricks. Among them, the removal of oxygen lance bricks is the most difficult...
