Embodiment Construction
[0012] The blast furnace tap hole splash press-in treatment process of the present invention is realized in this way, which will be described in detail below.
[0013] Implementation of the blast furnace tap hole splashing and pressing treatment process method of the present invention adopts the following process steps:
[0014] (1) Taphole cleaning: After the blast furnace is shut down, clean the area around the taphole, cut off the taphole protection plate frame outside the taphole cover, remove the taphole mud cover, and clean the joints between the taphole composite bricks;
[0015] (2) Welding of the taphole sealing plate: According to the design requirements of the blast furnace taphole, the thickness of the taphole sealing plate is increased by 30mm before construction starts, and the taphole sealing plate is welded on the large sleeve of the blast furnace taphole;
[0016] (3) Furnace skin opening: the drilling position is selected by calculation around the iron mouth ...
