Argon Blowing Monitoring System for Steel Furnaces

In steel production, mass flow controllers/meters play a crucial role, ensuring that the required gas enters the furnace at the correct proportions and flow rates under high pressure.

A steel company was seeking a suitable gas mass flow solution for its post-furnace argon blowing monitoring system. Based on its operating conditions, the steel company specified the following requirements:

  1. Due to the harsh environment of steel production, a high protection rating is required;
  2. Due to the high-pressure environment inside the furnace, the gas mass flow meter must be able to withstand high pressure differentials;
  3. The monitored media are argon and nitrogen;
  4. Continuous and stable monitoring is required during operation.

Furthermore, the steel company provided specific operating data, including flow range, accuracy, and pressure.

Sino-Inst, combining the operating data and specific requirements, customized a high-precision mass flow controller/meter, SI-20FD-L, for the client.

The parameters of this customized mass flow controller/meter are as follows:

  1. With pilot valve, pressure range: 0.3MPa~3MPa;
  2. Protection rating upgraded to IP65;
  3. Utilizes a large-range flow meter, range: 300SLM~3000SLM;
  4. Accuracy: 0.5±%F.S;
  5. Response time: 0.2s;
  6. Power supply voltage: 24V

This solution brings the following benefits to the customer:

High-Pressure Hydrogen Flow Control

The SI-20FD-L High Pressure Mass Flow Controller/Flow Meter is suitable for measuring pure gases, especially hydrogen. It can be used to measure the hydrogen flow rate in hydrogen refueling machines with pressures of 35MPa and 70MPa.

Hydrogen is an elemental gas formed from hydrogen. At room temperature and pressure, the density of hydrogen is 0.089 g/L (101.325 kPa, 0°C), only 1/14 that of air, making it the least dense gas known in the world. With increasing emphasis on clean energy, the application of hydrogen is becoming more and more widespread, and in practical applications, it is often necessary to measure or control the amount of hydrogen.

The SI-20FD-L High Pressure Mass Flow Controller/Flow Meter is well-suited for the characteristics of hydrogen due to its high accuracy and ability to implement electrical automation control. It has been widely used for the measurement and control of hydrogen flow, and has high airtightness, which can effectively avoid the risk of hydrogen leakage. In some special applications, an explosion-proof enclosure can also be added to meet design requirements.
