Embodiment Construction
[0008] The present invention will be described in detail below with reference to the drawings and specific embodiments.
[0009] In order to solve the problem of post-processing of the slag produced by the converter, the present invention provides a method for treating converter slag in a copper bath smelting furnace: a copper bath smelting furnace arch is installed with an inner hole communicating with the inside of the copper bath smelting furnace. The slag outlet water jacket 1, the slag return outlet water jacket 1 is provided with a sealing plug 2 at the entrance, and the slag return outlet water jacket 1 has one end with a sealing plug 2 connected to one end of the slag return chute 3. figure 1 As shown; the slag produced by the converter is poured into the slag return chute 3 through a slag bag with a 50-ton crane, the slag flows along the slag return chute 3 to the slag return water jacket 1, and the sealing plug 2 is opened. The slag enters through the slag return water j...

The invention provides a method for treating converter slag of a symmetrical full-slant copper melting pool smelting furnace. A slag return port water sleeve with an inner hole communicated with an inside of the copper melting pool smelting furnace is installed on a furnace arch of the copper melting pool smelting furnace, an inlet port of the slag return port water sleeve is connected with one end of a slag return sliding groove, the converter slag are sent to the slag return sliding groove, and the slag flows to the slag return port water sleeve along the slag return sliding groove and enters the copper melting pool smelting furnace through the slag return port water sleeve. An environment smoke collection system of a slag return port water sleeve of the copper melting pool smelting furnace is opened, overflowed SO2 (Sulfur Dioxide) smoke during slag returning is collected through the environment smoke collection system, and then the SO2 smoke is sent to a gas desulfurization system for desulfurization. The method can prevent the SO2 smoke in the slag from overflowing, reduces environmental pollution and can effectively recover copper in the slag.
Description
Technical field [0001] The invention belongs to the technical field of non-ferrous metal smelting, and relates to a method for treating converter slag in a symmetrical and fully inclined copper molten pool smelting furnace. Background technique [0002] Usually, the slag produced by the converter is cast into slag ingots with a slag casting machine, and then sent to the concentrator for slag selection. However, the structure of the slag casting machine is relatively complicated, the operation is unstable, and the failure rate is high, which cannot meet the needs of production. At the same time, the slag casting machine will have a large amount of SO during slag casting. 2 The flue gas overflows, causing serious low-altitude pollution. Summary of the invention [0003] In order to overcome the above-mentioned problems in the prior art, the purpose of the present invention is to provide a method for treating converter slag in a copper bath smelting furnace, which can prevent SO in t...
