Embodiment Construction

[0031] The embodiments of the present invention will be described in detail below with reference to the accompanying drawings, but the present invention can be implemented in many different ways defined and covered by the claims.

[0032] Copper staves are usually used to enhance cooling in areas with high heat loads in smelting blast furnaces, such as the bosh, waist and lower part of the furnace. Therefore the present invention corresponds to the different zones of the blast furnace, and the copper stave is made into a conical surface corresponding to the furnace shell ( Figure 1-4 in the first embodiment) or a cylindrical surface ( Figure 5-8 in the second embodiment). Below in conjunction with accompanying drawing, two typical forms of the present invention are described further.

[0033] Figure 1-Figure 4 shows the stave of the smelting furnace according to the first embodiment of the present invention. The staves in this embodiment are installed at the bosh positi...

Abstract

The invention provides a cooling wall for a smelting furnace. The cooling wall is arranged on the inner surface of a furnace shell of the smelting furnace; and the inner surface of the cooling wall of the smelting furnace is a circular arc surface. According to the copper cooling wall for the smelting furnace, which is provided by the invention, the circular arc surface is formed on the inner surface of the cooling wall for the smelting furnace, so that the slag adhering condition of the copper cooling wall is effectively improved and the service life of the copper cooling wall is prolonged.

Description

technical field [0001] The invention relates to the field of smelting furnace cooling equipment, in particular to a cooling wall of a smelting furnace. Background technique [0002] Copper staves are commonly used cooling equipment for ironmaking blast furnaces, and are usually manufactured by copper plate drilling and casting. The copper plate drilling stave is made of rolled or rolled pure copper plate as raw material and processed by machining. This copper stave avoids casting defects of cast staves, and has the advantages of high copper content, good thermal conductivity, fine grain, high density, and good mechanical properties. However, such staves are all made of planar copper slabs, so the plane layout of each layer of copper staves is an inscribed regular polygon of the corresponding blast furnace circumference. Since the upper and lower adjacent layers of copper staves are arranged in a staggered manner, the hot surface of the entire stave is a staggered regular p...
