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 Jingliang Technology. 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

Jingliang Technology, 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 Jingliang Technology'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 Jingliang Technology'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 Jingliang Technology in serving steel enterprises.

ACU10FA


The ACU10FA analog mass flow controller boasts fast response and high accuracy. It offers a wide control range, spanning 5 SCCM to 30 SLM, with the ability to measure and regulate flow as low as 1 SCCM, making it suitable for controlling very small flow rates.

ACU10FD


The ACU10FD digital mass flow controller consists of a mass flow sensor, a laminar flow element, a flow control valve, and an amplifier control circuit. It uses digital signal input and output and features a short preheating time, small zero drift, and high reliability.

ACU10FDR


The ACU10FDR low differential pressure gas mass flow controller, equipped with a proprietary high-flow electromagnetic valve, is suitable for controlling mass flow in situations with minimal available system pressure. The low differential pressure ensures minimal impact on the system, enabling flow control under near-atmospheric pressure conditions and reducing system response time. We will customize the valve and PID control functions for you based on your application parameters to ensure that the product can achieve fast and stable control while maintaining low pressure loss.

ACU10FC


The ACU10FC differential pressure mass flow controller uses a differential pressure mass measurement principle with no thermal drift and no response lag. It can simultaneously display and output: instantaneous flow rate, cumulative flow rate, pressure, temperature, etc. When a control function is required, an electromagnetic proportional control valve and built-in PID control function can be added. Unlike thermal flow meters, the ACU10FC has no additional "specific heat capacity" error when using gas conversion coefficients. Therefore, even if the measured gas is different from the calibration gas at the factory, it will not affect the measurement accuracy.

ACU10P


The ACU10P series pressure controllers/gauges feature a straight-through design with a measurement range from 100 kPa to 10 MPa (both absolute and gauge pressure). Differential pressure transmitters are also available.
