A steel company: High-pressure harsh environment contributes to precise measurement and control
Project Background: Steel Manufacturing, a Pillar Industry
China's steel output accounts for 54% of the global total. The steel industry is one of the country's pillar manufacturing industries and plays a pivotal role in the national economy.
In steel production, mass flow controllers/flow meters play a crucial role in ensuring that the required gases enter the furnace at the correct ratio and flow rate under high-pressure conditions.
Company Profile: Domestic Steel Enterprise with Annual Production of One Million Tons

A steel enterprise in Liaoning is one of the many steel companies served by ACCU. With an annual steel output of one million tons, it is one of the largest and most well-known steel companies in China, and also a major domestic research and production base for special steel.
Operating Conditions: Gas Measurement and Control under High Pressure and Harsh Environments
This steel enterprise previously used imported mass flow meters and is now seeking a suitable domestic gas mass flow solution for its post-furnace argon blowing monitoring system as part of a domestic substitution effort.
Based on the operating conditions, the steel enterprise has the following requirements:
1. Due to the harsh environment of steel production, the product must have a high protection level;
2. Due to the high-pressure environment inside the furnace, the gas mass flow meter must be able to withstand a high pressure difference;
3. The measured medium is argon and nitrogen;
4. During specific measurement and control operations, continuous and stable measurement and control must be maintained.
In addition, the steel enterprise provided specific operating data, including flow range, accuracy, and pressure.
Solution: Customized High-Precision ACU20FD Mass Flow Controller/Flow Meter
ACCU, combining operating data and special requirements, customized a high-precision ACU20FD mass flow controller/flow meter for the customer.
The parameters of this customized mass flow controller/flow meter are:
1. Uses a pilot valve, pressure resistance range: 0.3MPa~3MPa
2. Protection level increased to IP65
3. Uses a large-range flow meter, measurement range: 300SLM~3000SLM
4. Accuracy: 0.5±%F.S
5. Response time: 0.2s
6. Supply voltage: 24V
Project Benefits: Ensuring Stable and High-Quality Operations for Steel Enterprises
This steel enterprise adopted ACCU's customized solution and purchased a batch of customized high-precision ACU20FD mass flow controllers/flow meters for its post-furnace argon blowing monitoring system. This solution brought the following benefits to the customer:
1. Completed brand substitution, which is conducive to cost reduction and efficiency improvement
Faced with the continuous pressure on the steel market, this steel enterprise's substitution of cost-effective and stable domestic products ensures stable production of high-quality steel products and is also conducive to the company's better cost reduction and efficiency improvement.
2. Ensure normal operation and continuous production of high-quality steel products
After the brand substitution of the gas mass flow controller/flow meter, this steel enterprise continues to stably produce high-quality steel products.
Through ACCU's customized gas flow control solution, this steel enterprise has not only achieved brand substitution of gas mass flow controllers/flow meters, but also effectively ensured production efficiency and product quality. This case provides valuable reference for more steel enterprises and accumulates valuable experience for ACCU in serving steel enterprises.
