Description

Punching Apparatus for Blast Furnace Shell Protection Cooling Equipment

The present invention relates to a drilling device for a furnace shell protection cooling plant.

In general, operation of a blast furnace requires high pressure and high temperature operation, and generates a large amount of toxic gas.

It is covered with a thick iron sheath to prevent it from leaking to the outside.

Figure 2 is a photograph showing the wear state of the stave inside the furnace and a view showing the arrangement of the conventional drilling device. 3 is a photograph showing an example of a conventional drilling device. 4 is a cross-sectional view showing the design thickness of the FCD Stave and the width of the refractory material. 5 is a view showing an example of FCD Stave perforation. 6 is a view showing the position of the center hole to be drilled.

1 to 6 , a stave, which is a cooling device, and an irregular refractory material are installed inside the furnace to protect the shell.

However, long-term use of these leads to stave damage as the continuously descending kite, physical friction of raw materials and chemical wear of rising gas proceed.

At this time, when the cooling water enters the furnace, the water vaporizes, causing a sudden increase in gas volume and unstable operation due to cooling of the charge, which frequently leads to reduced production.

In addition, as the stave that protects the shell is removed, the high heat in the furnace (the shell in contact with the 1200°C gas is dented and damaged by carburization and thermal deformation, causing a fire and secondary There is a problem that leads to a major equipment accident.

The conventional stave material is 99.9% copper, and since the tip of the drill 100-d is easily damaged by frictional heat when drilling, lubricating oil is supplied to the lubrication supply line 100-a.

The conventional drilling device for anchor installation used a water jet method or a hydraulic drilling machine, but the FCD Stave cooling device is a technical problem in the installation inside the furnace. It is difficult to process.

The problem with the conventional "Blast Furnace Stave Drilling Device" is that the drill carbide is easily damaged by the vibrations generated during the drilling operation, resulting in poor work efficiency. e) was difficult to fix after insertion. (2 or more holes on the top and bottom are required for anchor installation)

The maximum forward stroke of the conventional Cupper Stave drilling machine is 350mm, and vibration occurs due to the structural defect of the holder (a), which causes frequent damage to the carbide tip and significantly lowers work efficiency.

Conventional hydraulic drilling machine is a method of fixing Holder (a) separately by welding (b) and fixing the drilling machine to the flange (c) part of the steel shell at the position to be drilled. There is a problem that the fixed round bar (e) is not inserted into the drilled hole (f) when installing the anchor (d) after drilling because the height (h) between the holes and the center do not match.

In the conventional drilling method, the boundary section (g) between Stave (A) and Stave (A) is arbitrarily measured outside the shell (A), and then the holder to fix the drilling machine is welded to the outside of the shell (A) and penetrated with one shot. If the initial location was not properly selected, the hole (f) to be drilled greatly deviated from the center line and damaged the Stave coolant line (C), or there was a big problem that the Anchor (d) could not be inserted.
