Embodiment Construction

[0058] Embodiments of the invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below by referring to the figures are exemplary and are intended to explain the present invention and should not be construed as limiting the present invention.

[0059] Such as figure 1 As shown, the transformation method of the top blowing smelting facility proposed according to the embodiment of the present invention includes:

[0060] The converter or blowing furnace in the original blowing process is canceled, and only the top-blown smelting furnace 14 and the sinking electric furnace in the original top-blown converting process are retained.

[0061] Reduce the hearth height of the top-blown smelting furnace 14 in the original top-blown smelting process. Preferably, the hearth height of the top-blown smelting furnace 14 is reduced to 6-8 meters. After lowering the hearth, the roof structure of the top-blown smelti...

Abstract

The invention discloses a modification method for a top-blowing smelting facility as well as a continuous copper smelting facility and method. The modification method for the top-blowing smelting facility comprises the following steps of removing a converter or a converting furnace of a top-blowing converting facility; reducing the hearth height of a top-blowing smelting furnace of the top-blowingsmelting facility; removing a single immersed top-blowing main spray gun of the top-blowing smelting furnace; arranging at least three top-blowing smelting spray guns on the top of the top-blowing smelting furnace at intervals; forming a copper matte draining hole in the top-blowing smelting furnace; removing an electrode and an electrode matching device of a settling electric furnace of the top-blowing smelting facility, and arranging at least three top-blowing smelting spray guns on the top of the settling instrument at intervals in order to modify the settling electric furnace into a top-blowing converting furnace; and connecting the copper matte draining hole of the top-blowing converting furnace with the copper matte inlet of the top-blowing converting furnace through a launder. Through adoption of the modification method for the top-blowing smelting facility, the existing top-blowing smelting facility can be utilized fully; the production of high-grade copper matte can be facilitated; conditions are created for continuous converting; and the investment cost of continuous copper smelting can be lowered.

Description

technical field [0001] The invention relates to the technical field of nonferrous metallurgy, in particular to a method for transforming a top blowing smelting copper smelting facility into a continuous copper smelting facility and the continuous copper smelting facility. Background technique [0002] Top blowing smelting technology is widely used in the smelting of copper, nickel, lead, tin, iron and zinc slag as well as copper and lead. The top-blown smelting technology was developed in the 1870s, and it was rapidly promoted from the end of the 19th century to the first decade of the 20th century. More than a dozen top-blown smelting plants were successively built in the field of copper smelting. However, with the development of copper smelting technology and the improvement of environmental protection standards, the operating cost advantage of top blowing smelting technology does not exist, and there is a need for upgrading. Contents of the invention [0003] The prese...
