Embodiment Construction

[0020] As shown in Figure 1-5, the power saving method of the oxygen lance cooling water feed pump in the present invention is to divide the oxygen lance water supply into different water supply periods, and change the water inlet or outlet opening of the oxygen lance cooling water according to the different water supply periods. That is to change the flow rate of different water supply periods, and the motor of the oxygen lance water supply pump adopts frequency conversion speed regulation, thereby reducing the consumption of electric energy of the oxygen lance water supply pump.

[0021] The present invention divides the oxygen lance water supply into the oxygen blowing water supply period, the slag splashing water supply period and the water supply period to be blown; the converter smelting cycle is generally 30 minutes, wherein the oxygen blowing time is 14 minutes, the slag splashing time is 3 minutes, and the time to be blown is 30 minutes. 13 minutes; the external ambien...

Abstract

The invention relates to a method for saving power consumption for an oxygen lance cooling water supplying pump. The method is characterized in that the oxygen lance water supply is divided into different periods for water supplying and the water inlet or outlet opening of the oxygen lance cooling water is changed according to the different periods for water supplying, namely, the water flow in the different periods for water supplying is changed. The oxygen lance cooling water supplying pump adopts frequency conversion to adjust the speed, thus reducing the power consumption by the oxygen lance cooling water supplying pump. The method of the invention has the advantages of simple method, consistency with actual situation, practicality and low cost and can solve the problems of the waste of water resources and electricity, thereby being an ideal method for saving power consumption for the oxygen lance cooling water supplying pump.

Description

1. Technical field: [0001] The invention relates to a method for saving electricity for a water feed pump in a converter steelmaking plant, in particular to a method for saving electricity for an oxygen lance cooling water feed pump. 2. Background technology: [0002] At present, the oxygen lance cooling water feed pump in the converter steelmaking plant supplies the same water regardless of the effective water supply period or the ineffective water supply period. Therefore, wasting water and electricity is the deficiency of the existing oxygen lance cooling water supply pump water supply method. 3. Contents of the invention: [0003] The object of the present invention is to invent a method for saving electricity for an oxygen lance cooling water feed pump, which is simple, practical, and low in cost; it can solve the problems of wasting water resources and wasting electric energy, so as to overcome The deficiencies in the method of feeding water to the water pump for the...
