Technical Field

The invention relates to the technical field of equipment detection and maintenance, in particular to a portable ultrahigh pressure water jet cutting mechanism for a cooling wall of a blast furnace.

Background

Usually, a plurality of sections of cooling walls are all installed at the furnace body position to the blast furnace and are cooled off the furnace body, and after the blast furnace used a certain age, the cooling wall can appear the water course and leak water, the cooling wall wearing and tearing even the phenomenon takes place that burns out, seriously influences the cooling effect of blast furnace, and then influences the normal production operation of blast furnace. The commonly adopted measures are that the cooling wall is provided with cylindrical micro-cooling through pipe penetration or drilling, but the cooling effect is limited, and the effect of protecting the furnace shell is not obvious. In order to effectively prolong the service life of the cooling wall, the ideal solution is to open holes for installing copper cooling plates, waist-shaped holes are required for installing the copper cooling plates, and the conventional hole opening mode is flame cutting or plasma cutting, but the thermal stress is concentrated, so that the furnace shell is greatly damaged, and the method is generally not suitable for being adopted.

The ultrahigh pressure water jet cutting belongs to cooling cutting, and does not cause material oxidation, change of metallographic structure and the like, and also does not cause workpiece deformation. Meanwhile, water and sand are used in the cutting process, no dust is generated, and the cutting method is green and environment-friendly. Therefore, the high-pressure water jet cutting is a relatively ideal technology for cutting and opening the blast furnace shell and the cooling wall.

The traditional water jet equipment can only improve the pressure and the flow rate by being provided with a huge equipment bracket and a complex pipeline, and needs larger working space. The existing high-pressure water jet device is mainly used for cleaning, pressure measurement, cutting and the like, the cutting is mainly thin-wall cutting (generally, the thickness is less than 40 mm), and the cutting thickness cannot meet the use requirement of blast furnace cooling wall cutting. For this reason, it is necessary to provide a portable ultra-high pressure water jet cutting mechanism for the furnace shell and stave of the blast furnace.
