Vacuum carburizing technology Demand for vacuum carburizing systems equipped with high-pressure gas quenching, oil quenching, or both has quadrupled since 2000, as the technology has replaced atmosphere carburizing and traditional oil quenching in many cases.
Typical Load of Tool & Die Components for Vacuum Heat Treating and High Pressure Gas Quenching (Photograph Courtesy of Nevada Heat Treating, Inc.) What is pressure quenching? The description most often used to define high pressure gas quenching is "accelerating the rate (speed) of quenching by densification and cooling of gas."
Vacuum furnaces for high pressure gas quenching have been used for almost thirty years. They have become increasingly favoured for hardening required thickness of some high strength steel elements (shown, for example, in Fig. 1). The quenching technology have progressed in recent years from furnaces with nitrogen at a pressure of 5 bars to systems
These high-pressure furnaces, from 5 to 12 bars, guarantee cooling rates that are compatible with the most demanding applications.These vacuum furnaces can be equipped with the convection technology to reduce the heating time and also to carry out homogeneous low-temperature heat treatments such as vacuum tempering cycles, often complementary to vacuum gas quenching.
For many years, vacuum furnace engineers and designers have been challenged to continue to improve gas quenching capabilities of these furnaces. The prime objective has always been to replace oil quench atmosphere furnaces with the very real advantages of high pressure gas quenching vacuum furnaces. This would result in the elimination of ©
ow Pressure Vacuum Gas Carburiz-ing (LPC) with High Pressure as Quenching (HPGQ) has received much attention recently. Batch and batch to batch heat treatment variability for case depth, core hardness and part distortion is a significant concern to the end user. A variable speed quenching process has been developed with results that show
generation" of dual vacuum furnace for low pressure carburizing and high pressure gas quenching, DualTherm®, was developed using proven technologies from the ModulTherm® series of vacuum furnace systems. The first furnace was recently installed at a commercial heat treater and is now in three-shift-operation. Dual chamber vacuum furnace
SuperTurbo ® High Pressure Quench. Gas-Quenching Vacuum Heat Treating Furnace for Large Loads. The Ipsen SuperTurbo ® is a superior vacuum furnace designed to handle large load capacities for the heat treating of dies, tools and parts with complicated geometries.
SECO/VACUUM Heat Treat Furnaces Manufacturers building for the North American Market with lowest lifetime cost for high temperature vacuum carburizing, gas nitriding, and vacuum brazing, high vacuum and with advanced technology furnaces built for single piece flow, high pressure gas quench, oil quench, and retort models.
The quenching pressure of vacuum high pressure gas quenching furnace is usually 2b a r ~ 10b a r. According to the requirements of the users, parts can be selected for pressure furnace type. 2, vacuum tempering furnace, vacuum tempering furnace can be divided into the single room, double room, and vertical usually choose nickel chromium with
Low pressure carburising with high pressure gas quench is primarily used for transmission gears and diesel fuel injectors that require a uniform carburised layer on every surface of the part, with minimal dimensional movement. The process produces a very clean surface, thus eliminating further post cleaning of the part after heat treatment.
Vector, An Advanced Vacuum Furnace with High Pressure Gas Quench Vector is a single-chamber gas quenching vacuum furnace using high pressure quench (2 to 25 bar) which can be applied to a wide variety of heat treating processes and applications.
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
Application Of High-Pressure Gas Quenching. The introduction of high-pressure gas quenching in vacuum furnaces in 1977 has given a new horizon to the vacuum heat treatment of tools. Before then, only some hot-work steels and a few other tool steels of small cross-section could be hardened satisfactorily.
low pressure carburizing (lpc) Low pressure carburizing (LPC), also known as vacuum carburizing or vacuum case hardening is achieved under vacuum, in a vacuum furnace. Since 1980's, ECM Technologies developed Infracarb®, the patented name for LPC processes.
Horizontal Twin Chamber Vacuum High Pressure Gas Quenching Furnace It is used for vertical gas quenching of materials like tool steel, die steel, high speed steel, super high strength steel, etc. The heating chamber is separated with the quenching chamber, which saves much energy and has good cooling.
