Embodiment Construction

[0042] see Figure 1-4 , the present invention includes the following steps:

[0043] The first step: equipped with four PS-converters and two high-pressure blowers;

[0044] Step 2: Divide the four PS-converters into two groups at random, wherein the first group is labeled No. 1 furnace and No. 2 furnace, and the second group is labeled No. 3 furnace and No. 4 furnace. figure 1 Among them, A represents No. 1 furnace, B represents No. 2 furnace, C represents No. 3 furnace, and D represents No. 4 furnace, and each group of PS-converters cooperates with a high-pressure blower respectively;

[0045] Step 3: After the PS-converter is heated up, start the high-pressure blower, so that each PS-converter is in a hot state to be smelted;

[0046] Step 4: Adjust the blowing process of the two PS-converters in each group of PS-converters, so that the blowing operation of each PS-converter is divided into three stages: the first slagging period (S1 period), the second Secondary slaggi...

Abstract

The invention relates to a blowing method of interchanging copper matte in an imperfect stage of PS-converters. The method is characterized by comprising the following steps: (1) preparing four PS-converters and two pressure blowers; (2) randomly dividing the four converters into two groups, wherein the converters in each group are matched with one pressure blower; (3) starting the PS-converters and the pressure blowers, wherein each converter is in a hot state to-be-smelted state; and (4) adjusting the blowing step of the converters in each group, wherein the stage B of one of the converters is just between the stage S1 and the stage S2 of the other converter; and during blowing, inserting one of the converters in one of the groups between the stages S1 and S2 of any one of the converters in the other group according to actual demand to realize the blowing operation. Compared with the conventional switching blowing method, the blowing method provided by the invention is low in cost, high in capacity and high in blowing efficiency, and in the blowing process, the blowing time ratio of the pressure blowers is high and the electric energy is greatly saved.

Description

technical field [0001] The invention relates to a blowing method, in particular to a PS-converter incomplete period interchangeable matte blowing method. Background technique [0002] At present, there are three main operation systems for blowing copper matte using PS-converter: single furnace blowing production, furnace exchange blowing production and periodic exchange blowing production. [0003] Single-furnace blowing production is suitable for small-scale smelters with only one PS-converter for production and one high-pressure fan for air supply. After a single PS-converter completes a cycle from feeding to copper output, it can be used after clearing the wind hole. The material is blown to carry out the next round of blowing production, and the air supply rate is about 63%; the furnace exchange blowing production is produced by two PS-converters, one high-pressure fan is used for air supply, and one PS-converter is produced after copper is produced. Switching to anothe...
