A sealed quench furnace is a type of industrial furnace used for the heat treatment of metal components. It is called a "sealed" furnace because it is designed to prevent the escape of heat and gases during the heating and cooling process. The furnace is typically used in the production of steel, aluminum, and other metal alloys.
During the heat treatment process, the metal components are placed inside the sealed quench furnace and heated to a high temperature, typically above the metal's recrystallization temperature. This allows the metal to be shaped and molded into its desired form. Once the metal has been heated to the appropriate temperature, it is quickly cooled, or quenched, in order to harden the metal and increase its strength and durability.
The sealed quench furnace is designed to provide precise temperature control and rapid cooling, ensuring that the metal is treated accurately and efficiently. It is often used in conjunction with other heat treatment equipment, such as tempering furnaces and annealing furnaces, in order to achieve specific mechanical properties in the metal.
The sealed quench furnace is a critical piece of equipment in many manufacturing industries, including the automotive, aerospace, and construction industries. It is used to produce a wide range of metal products, including structural components, engine parts, and other metal components.
Overall, the sealed quench furnace is an important tool in the heat treatment of metal, allowing manufacturers to shape and harden metal components to meet the specific requirements of their products.
Sealed Quench Furnace (SQF)
The double-walled housing execution with oil detector safely avoids environmental-damaging oil leakages. Quench time is a measure of how long a steel casting spends at high temperature during quenching. Quenching can also be accomplished using inert gases, such as nitrogen and noble gasses. It can also be used in other solution heat treatment processes up to 900°C 1652°F such as that for Titanium. If you have any differing views on this subject, your comments are most welcome. Do you have any questions or challenges regarding heat treatment? Carbonitriding is often applied to inexpensive, easily machined low carbon steel to impart the surface properties of more expensive and difficult to work grades of steel. Hand wheels are provided for the first drive adjustment and for the emergency operation.
Our Sealed Quench Furnace has pneumatically operated doors with wedge locking in the front and stainless steel inner casing. The sword and the crucible: a history of the metallurgy of European swords up to the 16th century. With the continuous chamber furnace, the charge is pushed into the first chamber by the charging table. It contains the heat treatment program in tabular form with all relevant part data, the standard and actual values of C-potential and temperatures in graphic form for the entire process duration, as well as the calculated carbon process in the parts in tabular form and in a diagram. An enclosed drive system with chains made of anti carburising alloy used in the charge transfer from heating to quenching chamber. The oil bath is protected against exceed of the allowed maximal temperature by rod temperature controller.
The second step in the quenching process is soaking. Electric resistance components made of graphite, ceramics, or metals heat the majority of vacuum furnace parts. These are best suited for applications like Annealing, Austempering, Carbonitriding, Carburising, Case hardening, Ferritic Nitro carburizing, Martempering and Normalizing. On these overview pictures, the position of the charge and all actual states of the drives, as well as the actual and standard value indication for C-level and temperature are displayed. In the vestibule chamber, the automatically working tray transport equipment is implemented.
The elevated furnace bottom door will open allowing the charge loaded basket to be lifted into the furnace. Caustics are the most severe quenchants, followed by oils, then salts and, finally, gases. As a safety backup, for excess temperature control, a non-indicating controller is provided. The vestibule chamber can be used additionally for charge cooling down to discharging temperature or for intermediate cooling isothermal annealing. What is meant by severity of quench? Moreover, ECO Furnaces can be integrated in existing batch lines, using the same peripherals and conveyors. .
The platform will be lowered into the stainless water quench tank immediately, fully immersing the hot loaded basket. It is stored on the hard disk and can be shown on the screen at any time. These oil-based fluids often oxidize and form a sludge during quenching, which consequently lowers the efficiency of the process. The control panel will be fully wired and tested before dispatch. The actual values are recorded by an oxygen probe measurement of the gas atmosphere in the furnace via zircon oxide. While as this type of facility is not available in in-out type sealed quench furnace. The program sequence can be pursued on-line via operator panel.
The cooperation of the high speeds of lowering platform and intermediate transport results in very short moving times; for example for the multi purpose chamber furnace size 3: start from the furnace chamber up to complete immersing into the oil bath approx. An intermediate door separates both furnace chambers. One can use our sealed quench furnace for various applications like case hardening and carburizing, carbonitriding, normalizing, annealing, ferritic nitrocarburizing, annealing and stress relieving. Beyond that, there is however still a multiplicity of development stages of the process control system, which can be extended up to the controlling of a fully automated multi purpose chamber furnace plant. This is done by heating the material to a certain temperature, depending on the material.
These controllers will act in conjunction with the thermocouples provided to sense the furnace temperature. Sealed Quench Furnaces are available in two types of designs. Often, after quenching, an iron or steel alloy will be excessively hard and brittle due to an overabundance of martensite. Hydro pneumatically operated quench elevator and inner door provide smooth shudder-free movement and trouble-free operation. This impressively proves the permanent high quality, reliability and economy of these plants. Different capacity and batch sizes are available to suit the optimum production requirement. Straight through pusher operation will enable a new basket to be loaded into the heating chamber while the old one is quenching.
Sealed Quench Furnace: SQF Furnace, Quenching Furnace Manufacturer in India
International Heat Treatment and Surface Engineering. The cooling rate of oil is much less than water. One type of Sealed Quench Furnace has two doors; one for loading the charge and one for unloading the charge. Technical specifications: Technical specifications: I TECHNICAL DATA 1 FURNACE type Straight through 2 Effective chamber Dimension 1230 mm L x 650 mm Ht. To find out details of the various heat treatment training courses which we are offering, please visit our website You can take a FREE TRIAL of any of our online courses.
We are always glad to hear from our Customers, It will be much appreciated if you please allow us to serve your esteemed organization. What is the hardness achieved in the carbonitriding process? Alternatively, the C-level-regulation can be carried out with software controllers of other selected measuring technology companies. Sealed Quench Furnace The multipurpose batch type chamber furnace plants or Sealed Quench Furnaces has revolutionized the heat treatment industry in the last few decades thanks to its versatility, easy integration in automatic treatment lines, providing flexibility of metallurgical processes, product mix and layout, with maximum quality heat treatment in terms of reliability, predictability and repetitiveness. They can design a complete solution for your specific requirements. With starting of a heat treatment program, the entire information is sent to the to the programmable controller PLC of the furnace plant. The sealed quenchable thermal barriers can be used in processes up to 1000°C 1832°F and are intended for frequent use. Journal de Physique Colloques, 1982, 43 C4 , pp.

I would like to invite all heat treaters to express their opinions and share their experiences in the comment section below. The heating chamber is at the back side and it is not directly in contact with open atmosphere.
