Sealed Quench Furnace (SQF) is used to heat-treat various metal components. This is the best option for high-precision, high-quality parts that require a controlled atmosphere and uniform temperature distribution. A Sealed Quench Furnace is suitable for processes like carburizing and carbonitriding. The initial higher investment costs provide superior process control, especially for complex and varied shapes. On the other hand, a Pit Furnace is a heat treatment furnace carried out in a cylindrical basket which is primarily suitable for bigger size components. It is a more cost-effective option, and suitable for simpler heat treatment processes where oxidizing during quenching is not critical.
Differences between a Sealed Quench Furnace and Pit Furnace
HIGHTEMP is the leading manufacturer of Sealed Quench Furnaces (SQF) in India by sales and selling globally. Some of the industries served include the automotive Industry, Aerospace Industry, and Consumer Industry.
Advantages of Sealed Quench Furnace over a Pit Furnace
Some of the key reasons why HIGHTEMP’s Sealed Quench Furnace might be a better option are-
Controlled Atmosphere with an Integral Quench Tank HIGHTEMP’s Sealed Quench Furnace integrated with the quench tank provides a protective gas atmosphere while reducing oxidation of the metal components during the quenching process.
Advanced Quenching Solutions Integral Quench Furnaces can incorporate advanced quenching solutions such as using inert gases like nitrogen to prevent reactions with quenching mediums.
Uniform Temperature Distribution due to Small Chamber Size The Sealed Quench Furnace is ideal for high-precision and high-quality parts, allowing for consistent heat treatment results.
Flexibility with more Heat Treatment Processes The SQF can handle a variety of heat treatment processes like carburizing, carbonitriding, and annealing, while a pit furnace handles simpler heat treatment processes.
Reduced Quenching Time The integral quench tank attached to the heating chamber can facilitate faster Quenching Processes by reducing oxidation and thereby providing better metallurgical properties. The quench time achieved in any sealed quench furnace is less than 30 seconds.
Reduces Distortion of Parts during the Cooling Process The Integral Quench Furnace reduces part distortion that can take place while heating during the cooling process while maintaining the integrity and dimension of the treated parts.
Precision of Products HIGHTEMP’s Sealed Quench Furnace has provisions to control the atmosphere temperature precisely allows for higher-quality end products with improved mechanical properties.
Reduces Risks of Contamination As the quenching medium is contained within a sealed furnace, the risk of contamination from dust or atmospheric gases are lower.
Enhanced Safety The automated process in HIGHTEMP’s Sealed Quench Furnace helps manage the risks associated with flammable quenching mediums and hazardous conditions.
Amount of Gas Consumed The emission of pollutants during the process is lower in the SQF when compared to a Pit Furnace due to reduced gas consumption.
Heat Recovery In SQF the doors are opened only for loading the job, hence the temperature of the furnace is not dropped much when compared to pit furnace. This helps improve overall energy efficiency.
Smart Manufacturing using Industrial IOT 4.0 Integration of HIGHTEMP’s Sealed Quench Furnace allows the user to connect to their equipment remotely, allowing for multiple ways to access data securely from the cloud.
Although the Sealed Quench Furnace may have higher initial costs, the costs incurred can be recovered quicker, and the Return on Investment (ROI) is usually better when compared to a Pit Furnace. Additionally, the sophisticated operation helps process control and quality, which makes the SQF a better heat treatment option compared to the Pit Furnace. HIGHTEMP’s Sealed Quench Furnace comes in various sizes and capacities. Additionally, HIGHTEMP can help guarantee consistent quality to meet the customers' requirements.
