High Pressure Gas Quenching Fu. it is applied for vacuum quenching high alloy steel such as high speed tool steel,mould st.<
The process of carbon restoration requires an atmosphere furnace using endo-thermic gas as the medium to add carbon to the surface of the components or castings. It is essentially a carburizing heat treatment and thus, it is critical for the furnace to have a system that controls the carbon content.
VAC AERO's IG Series Quench Gas Storage Systems are available as an option. A vertical vacuum furnace with gas quenching capability normally incorporates an external gas recirculating system to cool the inert quench gas used to extract heat from the load at the completion of the heating cycle.
The VTG series vacuum high-pressure gas quenching furnaces are mainly used for vacuum bright gas quenching of materials including cold/hot die steel, high-speed steel, die steel, stainless steel, Vacuum Brazing Furnace For Heat Exchanger
David Pye is known around the world as one of the heat treat industry's most knowledgeable consultants. Today he offers his thoughts on high pressure gas quenching in vacuum furnaces. "Work has been conducted on this quench technology for many years now.
The operating temperature of higher temperature furnaces is typically 1400°F to 1950°F as this is a radiant/conduction style of heat transfer to the load. Lower temperature styles for tempering or stress relieving are from 350°F to 1400°F and typically incorporate convection fans.

One of the important processes is surface hardening or carburizing. Heat the parts to 900 ° C to 1.000 ° C, and by adding the specific gases to the atmosphere in the furnace (hydrocarbons), by absorbing carbon to enrich parts surface. After this treatment, parts are quenched to obtain the desired properties.
Another heat treating equipment, the FireBox-HT is a high temperature furnace designed for both tool room heat treating and high temperature precision casting. For use up to 2,150 degrees F, the FireBox-HT is insulated with 4 1/2″ of firebrick backed up with an additional two inches of 1,200 degrees F block insulation.
For over 65 years, Lucifer Furnaces, Inc. has manufactured high quality heat treating furnaces and industrial ovens for businesses worldwide, from small Tool Rooms to large Corporations, Laboratories and Schools. Combining experience, capabilities and knowledge, we provide customized heat treating solutions.
When the steel (or any metal, or alloy) is heated as a separate operation of heat treatment to eliminate the residual stresses, it is then called stress-relieving annealing. It is an annealing heat treatment to relieve the stresses induced in parts to reduce the chances of warpage during subsequent heat treatment with no chance of crack formation.
The combination of quenching and tempering is important to make tough parts. This treatment follows a quenching or air cooling operation. Tempering is generally considered effective in relieving stresses induced by quenching in addition to lowering hardness to within a specified range, or meeting certain mechanical property requirements.
Best practice in heat treatment of large dies made of hot work tool steels by Maciej Korecki, Józef Olejnik, Piotr Kula, Emilia Wołowiec Tool steels are a widely used material for construction of tools designated for shaping and forming of metal, plastic and other elements in mass production.
Major advances in heat treating technology and furnaces have solved many of the problems commonly encountered. The newer 6-bar and 10-bar vacuum furnaces, for example, offer high pressure gas quenching capability which can profoundly affect the metallurgical quality of hardened tool steels.
