Problems solved by technology

However, the geometric thickness of the cast copper stave in the shape of a round tube is too large, the heat dissipation condition is poor, the production cost is high, and the metallurgical bonding strength between the tube and the wall is not very good.

Embodiment Construction

[0022] above figure 2 The disclosed structure is that of one embodiment of the present invention.

[0023] In the figure, 1 is the wall body of the cooling wall; 2 is the cooling pipe.

[0024] refer to figure 2 , during the implementation, the round steel pipe can be rolled and bent through the pipe bending machine, using a special mold, such as figure 2 The shape of the flat tube shown is put into the sand mold for casting. The processed flat cooling pipe is a meandering "serpentine" single pipe, and may also be composed of multiple (such as four) parallel single pipes. The material selected during processing can also be copper pipe or alloy pipe except steel pipe, and the specific implementation method is the same. The present invention is also applicable to the copper cooling stave of the rolling hole, that is, the cooling effect of the shape of the flat hole is better than that of the shape of the round hole.

Abstract

The invention relates to a method for processing a cast copper cooling wall of a blast furnace in the field of metallurgy. The processing method comprises the following steps: firstly, manufacturing acooling tube into a flat tube, then putting into a sand mould and casting. The cast copper cooling wall manufactured by the flat tube has better cooling effect in comparison with the prior circular tube cast copper cooling wall, i.e. the cooling effect of the flat tube can be enhanced by about 14.4% in comparison with the circular tube under the conditions of equal overflowing section, equal flowamount and equal flow rate. Simultaneously, the thickness of the cast copper cooling wall also can be reduced, a large amount of coloured component raw materials are saved, and the manufacturing costof a product is lowered. Furthermore, the metallurgical bonding strength of a tube and a wall body also can be enhanced.

Description

technical field [0001] The invention relates to the technical field of manufacturing blast furnace components of a metallurgical system, in particular to a processing method for a blast furnace cast copper stave. Background technique [0002] At present, the copper stave as the cooling part of the blast furnace is becoming one of the latest and most advanced technologies for the longevity of the blast furnace. At present, metallurgical enterprises at home and abroad have achieved success through the copper stave test and operation on the blast furnace, especially the copper stave product manufacturing technology on the large blast furnace has been widely used. [0003] There are three main types of copper stave manufacturing, namely rolling copper plate drilling, continuous casting with perforated slab and casting direct forming. Through independent innovation in recent years, WISCO has fully adopted cast copper cooling staves, which have been applied to five blast furnaces...
