Argon blowing control cabinet in the metal melting process

An argon blowing cabinet in the steel casting industry is used to enhance the metallurgical quality of molten steel. The technique involves injecting argon gas into the steel during the casting process, which helps to reduce impurities and improve metal properties.

Using argon in steel processing offers several benefits:

  1.  Reduction of Inclusions: Argon helps to minimize the presence of non-metallic inclusions in steel, leading to improved purity and quality.
  2. Enhanced Mixing: The introduction of argon promotes better mixing of molten steel, ensuring uniform composition and properties throughout the batch.
  3.  Improved Fluidity: Argon can enhance the fluidity of molten steel, which is beneficial during casting, allowing for better filling of molds and reducing defects.
  4. Deoxidation: Argon can assist in the deoxidation process, helping to remove oxygen from the molten steel, which can otherwise lead to oxidation and reduced quality.
  5. Control of Temperature: The use of argon can help maintain the temperature of the molten steel, which is crucial for achieving desired mechanical properties.
  6. Reduced Gas Porosity: By controlling the gas content in the steel, argon blowing can reduce the risk of gas porosity in the final product.
  7. Improved Surface Quality: The use of argon can lead to a smoother surface finish on cast products, reducing the need for additional machining.
  8. Cost-Effectiveness: While there is an initial investment in argon blowing equipment, the overall improvement in steel quality can lead to cost savings in terms of reduced scrap and rework.

These benefits make argon blowing a valuable technique in the steel casting industry, contributing to higher quality and more reliable steel products.

Several factors have been considered in the design of Alton Argon air control cabinet to ensure optimal performance and safety of the system. These factors include the following:

 1. Structural design:

  • Use of materials resistant to heat and corrosion.
  • Appropriate design to withstand argon gas pressure.

2. Control system:

  • Using accurate sensors to measure temperature and pressure from reputable brands.
  • Automatic control systems to adjust the flow of argon gas
  • Using Siemens PLC as the main controller and the heart of the control system

 3. Safety:

  • Installing safety systems to prevent gas leaks.
  • Using alarms and extinguishing systems in case of danger.

4. Gas flow:

  • Appropriate design of pipes and connections to prevent blockage and reduce pressure drop.
  • Using filters to prevent suspended particles from entering the system.

5. The detection mechanism of blocking the path:

  • At the beginning of each work cycle, you can fully automatically check the opening of the argon fluid passage using negative pressure reading technology.

6. Heat management:

  • Designing cooling systems to prevent temperature increase in the cabinet.
  • Use of suitable thermal insulation
  • Designing the system in such a way that it is suitable for use in the environment adjacent to molten materials.

7. Testing and evaluation:

  • Conducting the necessary tests to evaluate the performance of the system before launching.
  • Checking and optimizing the design based on the results of the tests.

8. Maintenance and repairs:

  • Cabinet design so that access to internal components is easy for maintenance.
  • Planning for periodic maintenance and checking system performance

The precise control of the amount of argon blowing is done according to the opposite diagram

  1.  Passing through the regulator filter in order to purify the gas entering the system and the initial adjustment of the working pressure by the operator
  2.  Measurement of initial pressure feedback by pressure transmitter or pressure gauge and displayed on the door of the control panel
  3. Passing the fluid through the mass flow controller and accurately adjusting the required flow rate as well as reading the flow rate feedback from the same equipment (in order to more easily supply spare parts and simplify the system, this part can be replaced by a professional flow rate and mass flow sensor, but it is recommended This company uses mass flow rate valve controller.
  4.  Fluid passing through the back pressure solenoid valve (this solenoid valve is used for the path clogging test process)
  5. Measuring the final pressure of injected argon accurately - at this stage, the sensor must be able to read the negative pressure accurately.
  6.  This whole step can pass through the bypass of the panel and be executed and read manually and locally so that the argon blowing process is not disturbed in emergency situations and power outages and lack of control by plc.
  • All the important measurement quantities (pressure and flow rate, etc.) can be read and viewed on the 7-inch screen on the door of the panel with high resolution, and this screen is protected by a resistant glass.
  • Using the push buttons on the door, the operator can easily adjust the desired quantities
  • All electronic and mechanical equipment are installed in a cabinet with a high degree of protection and are protected against the penetration of dust and heat.
  • In this cabinet, depending on the installation location and the amount of space intended for the cabinet, electrical and mechanical equipment can be installed in 2 separate compartments or compactly.
  • All the equipment used in the cabinet are from reputable European brands and the best in the market
  • FESTO - SIEMENS – ALTON
