Abstract

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

Symmetry full reclining formula copper bath smelting furnace is handled the method for converter slag
Technical field
The invention belongs to the non-ferrous metal metallurgy technical field, relate to the method that a kind of symmetrical full reclining formula copper bath smelting furnace is handled converter slag.
Background technology
Usually all use casting slag machine the slag casting slagging ingot that converter produces, send to the dressing-works again and carry out the slag choosing.But casting slag machine structure more complicated, fluctuation of service, failure rate is higher, can not meet the needs of production; Simultaneously, casting slag machine has a large amount of SO when the casting slag 2Flue gas is excessive, causes serious low vacancy pollution.
Summary of the invention
In order to overcome the problem that exists in the above-mentioned prior art, the purpose of this invention is to provide the method that a kind of copper bath smelting furnace is handled converter slag, can prevent the SO in the slag 2Flue gas is excessive, alleviates environmental pollution, the copper in again can the efficient recovery slag.
For realizing above-mentioned purpose; The technical scheme that the present invention adopted is: a kind of symmetrical full reclining formula copper bath smelting furnace is handled the method for converter slag; The return slag saliva cover that endoporus communicates with copper bath smelting furnace interior is installed on copper bath smelting furnace chimney arch, and the ingress of return slag saliva cover is connected with an end of return slag chute, and converter slag is sent into the return slag chute; Slag flows to return slag saliva cover along the return slag chute, and covers in the copper bath smelting furnace through return slag saliva; Meanwhile open copper bath smelting furnace return slag saliva set of environments collection cigarette system, excessive SO during with return slag through set of circumstances cigarette system 2Deliver to desulphurization system after flue gas is collected and carry out desulfurization.
The inventive method is sent into converter slag in the smelting furnace from copper bath smelting furnace top, carries out secondary smelting, saves casting slag machine, has stopped SO in the slag 2Smoke spillage, pollution on the environment, the copper in the efficient recovery converter slag improves output simultaneously, reduces cost; And improved operating environment, reduced labor intensity of operating personnel.
Description of drawings
Fig. 1 is the structural representation of converter slag being sent into the device of copper bath smelting furnace that adopts in the inventive method.
Among the figure: 1. return slag saliva cover, 2. sealing plug, 3 return slag chutes.
Embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is elaborated.
In order to solve the aftertreatment problem of converter output slag; The invention provides a kind of copper bath smelting furnace and handle the method for converter slag: the return slag saliva cover 1 that endoporus communicates with copper bath smelting furnace interior is installed on copper bath smelting furnace chimney arch; Return slag saliva overlaps 1 ingress sealing plug 2 is set; The end that return slag saliva cover 1 is provided with sealing plug 2 is connected with an end of return slag chute 3, and is as shown in Figure 1; Pour the slag of converter output into return slag chute 3 through cinder ladle with 50 ton overhead travelling cranes, slag flows to return slag saliva cover 1 along return slag chute 3, opening encapsulation plug 2, and slag gets in the copper bath smelting furnace through return slag saliva cover 1; Meanwhile open copper bath smelting furnace return slag saliva set of environments collection cigarette system, excessive SO during with return slag through set of circumstances cigarette system 2Deliver to desulphurization system after flue gas is collected and carry out desulfurization.
Adopt the inventive method can prevent the SO in the slag 2Flue gas is excessive, alleviates environmental pollution, the copper in again can the efficient recovery slag.
