Abstract
The invention provides a kind of method of symmetrical full reclining formula copper bath smelting furnace process converter slag, what copper bath smelting furnace chimney arch installed endoporus communicates with copper bath smelting furnace interior returns slag notch cooler, the ingress returning slag notch cooler is connected with one end of return slag chute, converter slag is sent into return slag chute, slag flows to along return slag chute and returns slag notch cooler, and covers in copper bath smelting furnace by return slag saliva; Open copper bath smelting furnace return slag saliva set of environments collection cigarette system, by ugitive gas collection system by SO excessive during return slag
2deliver to desulphurization system after fume collection and carry out desulfurization.Present method can prevent the SO in slag
2flue gas is excessive, alleviates environmental pollution, again can copper in efficient recovery slag.
Description
Technical field
The invention belongs to non-ferrous metal metallurgy technical field, relate to a kind of method of symmetrical full reclining formula copper bath smelting furnace process converter slag.
Background technology
Usually all use casting slag machine that the slag that converter produces is cast slagging ingot, then send to dressing-works and carry out slag choosing.But casting slag machine complicated structure, fluctuation of service, failure rate is higher, can not meet the needs of production; Meanwhile, cast slag machine and have a large amount of SO when casting slag
2flue gas is excessive, causes serious low vacancy pollution.
Summary of the invention
In order to overcome above-mentioned problems of the prior art, the object of this invention is to provide a kind of method of copper bath smelting furnace process converter slag, the SO in slag can be prevented
2flue gas is excessive, alleviates environmental pollution, again can copper in efficient recovery slag.
For achieving the above object, the technical solution adopted in the present invention is: a kind of method of symmetrical full reclining formula copper bath smelting furnace process converter slag, what copper bath smelting furnace chimney arch installed endoporus communicates with copper bath smelting furnace interior returns slag notch cooler, the ingress returning slag notch cooler is connected with one end of return slag chute, converter slag is sent into return slag chute, slag flows to along return slag chute and returns slag notch cooler, and covers in copper bath smelting furnace by return slag saliva; Meanwhile open copper bath smelting furnace return slag saliva set of environments collection cigarette system, by ugitive gas collection system by SO excessive during return slag
2deliver to desulphurization system after fume collection and carry out desulfurization.
Converter slag is sent in smelting furnace from copper bath smelting furnace top by the inventive method, carries out secondary smelting, saves casting slag machine, has stopped SO in slag
2smoke spillage, pollution on the environment, the copper simultaneously in efficient recovery converter slag, improves output, reduces costs; And improve operating environment, reduce the labour intensity of operator.
Accompanying drawing explanation
Fig. 1 is structural representation converter slag being sent into the device of copper bath smelting furnace adopted in the inventive method.
In figure: 1. return slag notch cooler, 2. sealing plug, 3 return slag chutes.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention is described in detail.
In order to solve the aftertreatment problem of converter output slag, the invention provides a kind of method of copper bath smelting furnace process converter slag: that on copper bath smelting furnace chimney arch, installs that endoporus communicates with copper bath smelting furnace interior returns slag notch cooler 1, return slag notch cooler 1 ingress and sealing plug 2 is set, return one end that slag notch cooler 1 is provided with sealing plug 2 to be connected with one end of return slag chute 3, as shown in Figure 1; Pour the slag of converter output into return slag chute 3 by cinder ladle 50 ton overhead travelling cranes, slag flows to along return slag chute 3 and returns slag notch cooler 1, opening encapsulation plug 2, and slag enters in copper bath smelting furnace by returning slag notch cooler 1; Meanwhile open copper bath smelting furnace return slag saliva set of environments collection cigarette system, by ugitive gas collection system by SO excessive during return slag
2deliver to desulphurization system after fume collection and carry out desulfurization.
Employing the inventive method can prevent the SO in slag
2flue gas is excessive, alleviates environmental pollution, again can copper in efficient recovery slag.
