What is Sealed Quench Furnace and Where is it Applicable?
Sealed Quench Furnace (SQF) is a batch type heat treatment furnace for controlled-atmosphere hardening and other related processes like carburizing, carbonitriding, annealing, normalizing, and tempering. It is widely employed for the surface of steel parts that need to be hardened and have desirable mechanical properties.
In a "sealed quench furnace", the components are placed inside a "sealed" treatment chamber where they are treated in a controlled atmosphere. Carbon-rich gases can be used for carburizing or process gases which are appropriate for the process can be used for carbonitriding. The process can then be followed by washing and tempering.
How Does our Sealed Quench Furnace Work?
The treatment chamber is loaded with components using suitable trays, baskets or fixtures.
As SQF Suppliers in Pune, furnace is heated to the required process temperature using controlled heating elements.
For carburizing applications, carbon: rich process gases are controlled according to the required case depth.
After completion of the heating and case: hardening cycle, the components are transferred or quenched in a controlled quenching medium.
Oil temperature, agitation and quenching conditions are controlled according to the material and component requirements.
The treated components are unloaded after completion of the heat treatment cycle and inspection.
What are the Types of Sealed Quench Furnace Used in Industries?
As prominent Sealed Quench Furnace Manufacturers in Pune, we provide furnace configurations according to component size, production volume, heat treatment process and metallurgical requirements.
Batch Type Sealed Quench Furnace: Designed for processing components in batches. It is suitable for automotive, engineering, gear, bearing, tooling and general industrial applications where flexibility and repeatable heat treatment are required.
Carburizing Sealed Quench Furnace: Specifically designed for carburizing steel components. Carbon is introduced into the surface of suitable components to achieve a hardened case while maintaining a tougher core.
Carbonitriding Sealed Quench Furnace: Uses a controlled carbon and nitrogen atmosphere to produce a hard and wear resistant surface layer. It is suitable for smaller components requiring improved surface hardness and wear resistance.
Oil Quench Sealed Quench Furnace: Designed with an integrated or connected oil quenching system for controlled hardening of components. Quenching parameters can be managed to achieve the required hardness while controlling distortion.
Multi-Purpose Chamber Sealed Quench Furnace: Designed for processing different types of heat treatment cycles such as carburizing, carbonitriding, hardening and other controlled-atmosphere processes. SQF systems can be customized according to production requirements.
