Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of cutting machines, in particular to a water cutting device for repairing a steelmaking blast furnace. Background Art
[0002] Steelmaking furnace is a device used to produce steel, mainly used to melt metal materials and refine them. The steel production process mainly includes raw material preparation, smelting, pouring, forming and heat treatment. During the overhaul of the steelmaking furnace, it is necessary to replace the refractory material, replace the furnace cooling device, and repair the damaged furnace body.
[0003] Since the outer lining steel plate of the furnace is too thick and the inner lining material is special (generally a 50mm copper plate for the lifting platform), the use of hollow drills and flame cutting to cut the furnace body is labor-intensive, the processing cost is high, the later repair welding cost is even higher, and the maintenance cycle is long, so water jet cutting machines are more preferred. Water jet cutting machines are machines that use high-pressure water jets to cut. Water jet cutting machines are currently the most productive machines in the world. Water jet cutting machines are superior to other processing technologies. At the same time, water jet cutting machines do not produce harmful gases or liquids, and do not generate heat on the surface of the workpiece. It is truly a multifunctional, efficient, cold cutting process.
[0004] However, there are many pipelines on site, the lines are complicated, and the effective space is very small. The large machinery and mechanical arms of the existing water jet cutting machines cannot be fully utilized, and the construction cannot be effectively organized, so the practicality is low.
