Method for packaging high-furnace cooling wall

Abstract

The invention relates to a method for packaging a high-furnace cooling wall, comprising the following steps: overlapping the outer walls of two high-furnace cooling walls back to back so that an inletand outlet pipe opening is protected by the two cooling walls; installing a prefabricated packaging bracket on a packaging cross arm of each cooling wall so that the two cooling walls form a firm integrity with an inward outer wall convex cambered surface inlet and outlet pipe opening and an outward inner wall concave cambered surface to ensure safety and reliable storage, transportation as wellas assembly and disassembly, wherein the packaging cross arm of each cooling wall is made of round steel or profile steel; the packaging cross arms of the two cooling walls are respectively arranged at the left side and the right side of the cooling wall with a space of 20-90 percent of the length of the cooling wall, and cast together with a high-furnace cooling wall body to ensure that the packaging bracket obtains a firm and effective fulcrum; the packaging bracket of the cooling wall is made of profile steel or the whole block of steel plate and welded with the packaging cross arm of the cooling wall or fastened together with a screw.

Description

technical field [0001] The invention relates to a method for packaging cooling staves of a blast furnace, and belongs to the field of packaging and transportation of large and medium-sized parts of metallurgical equipment. Background technique [0002] The blast furnace cooling stave is a key component of the ironmaking blast furnace. According to its installation in the blast furnace, it is divided into six walls: inner, outer, upper, lower, left, and right. The inner and outer walls are centered on the center line of the blast furnace. The concentric arc surface is the key working surface of the stave. The inner wall faces the furnace core and is arranged in the form of a plane or inlaid bricks. A group or groups of cooling water pipes are installed on the outer wall to force water to cool the stave of the blast furnace when the blast furnace is working. Safe operation of the blast furnace; depending on the location of the blast furnace model, the cooling stave ranges from...

[0002] The blast furnace cooling stave is a key component of the ironmaking blast furnace. According to its installation in the blast furnace, it is divided into six walls: inner, outer, upper, lower, left, and right. The inner and outer walls are centered on the center line of the blast furnace. The concentric arc surface is the key working surface of the stave. The inner wall faces the furnace core and is arranged in the form of a plane or inlaid bricks. A group or groups of cooling water pipes are installed on the outer wall to force water to cool the stave of the blast furnace when the blast furnace is working. Safe operation of the blast furnace; depending on the location of the blast furnace model, the cooling stave ranges from several hundred kilograms to several thousand kilograms. Reasonably cause stave damage and scrapping, causing serious economic losses, forcing relevant companies to continuously strengthen product packaging, so that the packaging cost reaches 10-15% of the product cost, but due to the lack of reasonable packaging methods, it is still difficult to eliminate the problems caused by packaging problems. loss
