Our vacuum quench furnaces can quench work from temperatures as high as 2150°F (1175°C). We use nitrogen or argon for quenching at pressures up to 60 psig (5 bar). Our continuous pressure quench furnace is unique in that it is capable of producing cool rates approaching that of oil yet with minimal distortion associated with gas quenching.
Jun 12, 2014 · Carburizing was performed at 960°C (1760°F) for 3.34 hours followed by either oil quenching (variable agitator speed) or high pressure gas quenching. Targeted surface carbon content was 0.72%C (vacuum) and 0.80 -0.90%C (atmosphere).
The Super Fast Quench Vacuum Furnaces (SFQ Series) are G-M's high pressure quenching furnace. Like the 3QTM Series, the SFQ Series is equipped with a post cooler heat exchanger which provides lower gas temperature quenching than any other gas cooling system offered in the market place up to date.
For their use as cooling media in vacuum furnaces, they have to be optimized by proper adjustment of the gas pressure and flow speed. Figure 12 shows an approximate comparison of average HTCs between liquid quenchants and high-pressure gas quenching (HPGQ) technology used in vacuum furnaces (9). A big difference is to be observed between
Jun 11, 2003 · Universal HPQ(tm) high pressure quench furnaces with optional low-pressure vacuum carburizing provide the process functionality of standard furnaces with high-pressure quenching including hardening, tempering, annealing, aging, solution heat treatment, brazing and sintering operations in a single furnace, combined with low-pressure vacuum carburizing.
Quench Vacuum Furnace COOLING GAS Vacuum Chamber Double wall, water cooled, horizontal front loading vacuum chamber. Hinged front door with pneumatically operated, autoclave-type locking ring to permit the furnace to safely quench at positive pressures up to 285 PSIG (20-bar). Oversized water inlets and outlets assure maximum water flow.
generate sufﬁciently high heat transfer coefﬁcients, and to produce cooling which results in minimal distortions and most uniform mechanical properties of the quenched parts. A review of the cooling process in gas quenching, including ﬂow in quench chambers, furnaces, and their components, and cooling of single and multi-body quench charges is
Horizontal Type Double Chamber Vacuum High Pressure Gas Quenching Furnace Horizontal gas quenching furnace is used for gas quenching of materials like tool steel, die steel, high speed steel, super high strength steel, etc.
Vacuum Metallurgy. Vacuum metallurgy involves vacuum processes for treating molten metals such as melting and remelting, casting and metal-powder technology as well as specialized vacuum coating technologies for high temperature turbine components.
Once the workload is properly "cased", the metal is quenched using oil or high pressure gas (HPGQ). For HPGQ, nitrogen or, for faster quench helium, is commonly used. This process is also known as case hardening. Another low temperature application of vacuum furnaces is debinding, a process for the removal of binders.
The quenching chambers in high pressure are used in combination with vacuum furnaces for low pressure carburizing for the heat treatments.
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 highest heating temperature is 800 ℃.
VACUUM QUENCHING OILS DURIXOL vacuum quenching oils provide controlled, low-stress quenching characteristics and are easily degassed. The oils have only a low tendency to absorb moisture and enable particularly bright component surfaces. The oils are designed especially for use in vacuum furnaces with integrated oil baths.
High temperature, Cold walled, high pressure vacuum furnace with oil/gas quenching facility . Vacuum heat treatment prevents distortion of the material and provides an oxidation free surface. HHV's cold - walled horizontal vacuum heat treatment furnace has oil and gas quenching capability. The furnace has a horizontally mounted double walled water cooled chamber fabricated with carbon steel in accordance with ASME code.
For gas quenching furnace, suit to deal with a higher hardenability materials of pressure gas cooling rate is smaller than the cooling speed of quench oil a lot;..<
Paulo's approach to solution treating. One-cycle solution treat and age, decreasing handling time and improving turnaround Fast cooling in high-pressure quenching vacuum furnaces to maintain desired microstructures Vacuum furnace design to eliminate oxidation, alloy depletion, carbon pickup and surface contamination Specialized fixturing
Apr 13, 2018 · When treating titanium alloy with vacuum furnace, nitrogen should not be used as the cooling gas, because titanium and nitrogen react at high temperature to form yellow titanium nitride.
About 79% of these are industrial furnace, 12% are laboratory heating equipments, and 1% are industrial heater. A wide variety of vacuum quenching furnace options are available to you, such as resistance furnace, induction furnace, and arc furnace.
Horizontal Double Chamber Vacuum High Pressure Gas Oven Temple Description The horizontal gas quenching furnace is used for the quenching of materials such as tool steel, die-cast steel, high speed steel, super high strength steel, etc.
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.
