The invention discloses a pressing
system restraining a
blast furnace hearth plate from warping upwards and application thereof and belongs to the technical field of
blast furnace equipment transformation. The pressing
system comprises a pressing device, an annular check ring and castable material. The section of the main body of the pressing device is shaped like a Chinese character "tu" of a left-right
asymmetry structure and comprises a pressing plate, a bottom plate and a bolt, wherein the pressing plate and the bottom plate are parallel, the bolt penetrates through the pressing plate so as to be fixedly connected to the bottom plate, and the height of the pressing plate is regulated by a nut. The bottom plate of the pressing device is inserted into the bottom of the
blast furnace hearth plate warping upwards and presses on the top of a blast furnace
hearth closing plate warping upwards through the pressing plate. The castable material fills the gap, formed by the blast furnace hearth closing plate warping upwards and the pressing device, in the furnace hearth. The annular check ring surrounds the outer side of the pressing device. According to the application of the pressing
system, through the steps of calculating, laying, fixing, pressing, preparation before pouring, pouring, solidifying and the like, the influence caused by upward-warping of the blast furnace hearth closing plate is removed, production of a blast furnace is stabilized, various economic and technical indexes of production of the blast furnace are maintained, and the technological operation of the blast furnace is effectively guaranteed.
