[0002] The blast furnace is made of steel plates with a refractory brick lining inside. The blast furnace is divided into five parts from top to bottom: the throat, body, waist, bosh, and hearth. Due to the advantages of blast furnace ironmaking, such as good technical and economic indicators, simple process, large production volume, high labor productivity, and low energy consumption, this method of iron production accounts for the vast majority of the world's total iron production.

[0003] After the blast furnace is formed, its furnace body needs to be opened. In the prior art, when opening the iron mouth of the blast furnace, a wind rod (Ø50mm drill bit) is first used to open a section, then a wind rod (Ø40mm drill bit) is used to open a section, and finally a spear made of round steel is used to open the iron mouth. The opening process is relatively cumbersome. Therefore, the present invention proposes a rapid opening device for a blast furnace. Summary of the Invention
