Energy saving of seamless steel pipe production line retrofitting saving rate 80%

15 years of professional reform experience create brilliant in market

1. Description of iron and steel industry current situation

Iron and steel industry is the basic industry of national economic construction, and it is also a high energy consumption industry. Its energy consumption accounts for about 15% of the total national energy consumption. Therefore, the iron and steel industry has always been the focus and difficulty of energy conservation.

In the production line of iron and steel plant, the hydraulic system is the main source of its operation power. The improvement of hydraulic system efficiency can play a key role in energy saving and emission reduction of enterprises. It has the following characteristics:

1) The pump station is centralized, the control valve station is scattered, and the actuator is in many aspects.

2) High pressure, large flow, integrated installation.

3) Cartridge valve, proportional valve and other high-precision control valves are widely used.

4) The actuator has the advantages of frequent action, high speed and fast response.

5) The hydraulic system is located in a bad environment, which is greatly affected by high temperature, dust, corrosion and vibration impact.

6) Equipment continuous operation, often not enough time for maintenance of the hydraulic system.

2. Energy saving of seamless steel pipe production line

According to the nature of the hydraulic station and the number of main pumps, working principle and characteristics, combined with the process requirements of each region, as well as the load of the equipment, the servo upgrading improvement scheme of the system is determined.

According to the actual feedback demand, output on demand to avoid the system to do idle work, to achieve energy-saving effect.

Using high-resolution position sensor and pressure sensor for feedback control, the closed-loop control of roll position can be realized to achieve high-precision gap adjustment.

In order to improve the quality of products and optimize the use of the whole plant, the original pipe rolling mill was reformed and the control and management of the production process was strengthened.
