Problems solved by technology

[0007] However, due to limitations in the use of the cooling function of the cooling plate, it is difficult to continue the cooling of the iron sheet stably for a long time, especially the refractory material is easy to fall off, causing a thermal load in a short time and the cooling water line of the cooling wall is repeatedly damaged , so there is a problem that the maintenance cycle of refractory materials is shortened and the maintenance cost is increased

Embodiment Construction

[0022] In the following, the present invention will be described in detail by means of exemplary drawings. When assigning reference numerals to constituent elements in each drawing, care should be taken to assign the same reference numerals as much as possible even if the same constituent elements are shown in different drawings. In addition, when describing the present invention, when it is judged that the detailed description of related known structures or functions may make the gist of the present invention unclear, the detailed description thereof will be omitted.

[0023] According to the setting method of the stave protection device of the present invention, the step of perforating the iron sheet and the stave of the furnace body; the step of inserting the stave protection device to the inboard of the furnace body; The step of drawing out and fixing to the outside of the stave; and the step of spraying a refractory material toward the above-mentioned stave so that the st...

Abstract

The invention relates to a cooling wall protection device and an arranging method thereof. The method comprises the following steps: creating a hole in the iron sheet and cooling wall of a furnace body, inserting the protection device into the inner side of the furnace body, pulling the fixing part of the protection device to the external side of the iron sheet so as to fix the protection device; and spraying a fireproof material in a mode that the protection device is buried. The dropping of fireproof material is maximally reduced. The phenomenon that the iron sheet is heated and damaged due to the falling of fireproof material is avoided. The danger is reduced.

Description

technical field [0001] The present invention relates to a stave protection device attached to a stave of a blast furnace to protect the stave and iron sheet of the blast furnace and an installation method thereof. Background technique [0002] Generally speaking, blast furnaces are used as equipment for continuously producing molten iron (hereinafter referred to as "liquid iron") for 24 hours. hot air"). [0003] The hot air entering the tuyeres reacts with coke, which is fuel, to generate high heat of 2200-2400°C, which is used to melt iron ore, the raw material loaded, to produce molten iron. The produced molten iron is discharged through the molten iron discharge port located below the tuyere. [0004] On the inner surface of the iron sheet of this blast furnace such as figure 1 Shown is a stave 30 provided with cooling water pipes 32 that circulate and supply cooling water to protect the steel sheet 10 from the high heat generated inside the blast furnace 100 . Moreo...
