High Pressure Gas Quenching (HPGQ) - ALD Heat-Treatment ...During High Pressure Gas Quenching (HPGQ) previously austenitized respectively thermochemically treated parts are quenched in an inert gas flow in a pressure range between 1 bar and 20 bar with gas velocities between 0,5m/s and 20m/s. Depending on the geometry and the steel-grade of the quenched component, either helium or nitrogen is used.

With High Pressure Gas Quenching (HPGQ), parts are rapidly cooled by using a pressurized gas such as Nitrogen or Helium. Hardening is a highly nonlinear process due to the plastic deformation caused by thermal stresses and phase transformations, both of which lead to distortion. Reducing distortion caused by hardening has always been pursued by high pressure gas quenching hpgqMATHEMATICAL MODELLING - Quenching Research High pressure gas quenching To simulate different parameters for high pressure gas quenching (HPGQ) in vacuum furnaces (different gases, pressures and flow velocities), a modified Jominy specimen (20 mm Dia. × 100 mm) is heated by induction and cooled in this facility under controlled conditions.Interest in high-pressure gas quenching (HPGQ) increases high pressure gas quenching hpgqHydrogen for high-pressure gas quenching (HPGQ) has the highest thermal conductivity and heat capacity of any commercially available gas, but currently is not used due to safety concerns in commercial high pressure cooling applications. Somewhere, however, in a secret laboratory it receives research activity.
High Pressure Gas Quenching: The Key to Long H13 Insert Life. HPGQ vacuum furnaces have the ability to harden parts of various materials, sizes, and geometries, in a clean, efficient, and effective way, including hand tools, gears, bearings, shafts, etc. HPGQ (High Pressure Gas Quench) has a number of key design features that provide this capability.High Pressure Gas Quenching (HPGQ) - ALD Heat-Treatment high pressure gas quenching hpgqDuring High Pressure Gas Quenching (HPGQ) previously austenitized respectively thermochemically treated parts are quenched in an inert gas flow in a pressure range between 1 bar and 20 bar with gas velocities between 0,5m/s and 20m/s. Depending on the geometry and the steel-grade of the quenched component, either helium or nitrogen is used.Heat Transfer Control During Quenching: Materials and high pressure gas quenching hpgqHigh Pressure Gas Quenching (HPGQ) in vacuum furnaces is especially prone to changing some parameters during quenching. To increase its quenching intensity, in order to attain high enough hardness in the core, the gas pressure and/or its flow velocity can be increased.
That presents two options: oil press quenching and HPGQ (high pressure gas quenching). Press quenching except for unique considerations can only be practically done with continuous furnaces mainly pushers, whereas HPGQ is a batch process. Thats not to say HPGQ couldnt be employed from pushersits been done, by AFC-Holcroft.Everything about High Pressure Gas Quenching - Hydrogen, although excellent with respect to heat transfer, is seldom used as a quench gas due to safety considerations. High Pressure Gas Quenching (HPGQ) offers a number of attractive benefits including unprecedented part cleanliness and less overall dimensional change. Fixed or variable cooling rates are applied as required to control hardness and distortion with the ability to vary quench pressure Brief introduction to the new quenching process - Meetyou high pressure gas quenching hpgqMay 22, 2019 · When quenching with 20×105 Pa ultra-high pressure nitrogen or a mixture of helium and nitrogen, the density of the cooled load is 80%-150% higher than that of 6×105 Pa nitrogen cooling, which can cool all high-speed steel and high-alloy steel. , hot work die steel Cr13% chrome steel, and more alloy oil quenched steel, such as larger size high pressure gas quenching hpgq

Applications of quenching services include steel & varied part geometry such as truck half-axles, HPGQ-SAMTCHPGQ. HIGH PRESSURE GAS QUENCHING. For many years now, gas quenching has been the preferred process in the heat treatment of high-speed steels and hot and cold working tool steels. With the development of separate gas quenching chambers, it is often possible to replace oil quenching with high-pressure gas quenching using nitrogen or helium for high pressure gas quenching hpgq
HPGQ stands for High Pressure Gas Quenching (steel heat treatment) Suggest new definition. This definition appears somewhat frequently and is found in the following Acronym Finder categories: Science, medicine, engineering, etc. Link/Page Citation Abbreviation Database Surfer high pressure gas quenching hpgqGas Quenching | Steel Heat Treating Fundamentals and high pressure gas quenching hpgqThe gas quenching process is usually performed at elevated pressures, and is therefore, mostly referred to as high-pressure gas quenching (HPGQ). This article describes the physical principles of HPGQ; the two main types of equipment used, namely, single-chamber furnaces and cold chambers; and the three gases used, namely, nitrogen, helium, and high pressure gas quenching hpgq4D high-pressure gas quenching | Thermal Processing Jul 15, 2020 · 4 4D High Pressure Gas Quenching. 4D HPGQ is a new process that allows for significant improvements to the quenching process with the main focus on reduction of distortion. Distortion reduction is achieved mainly from the use of a high-pressure gas quenching system installed in the quenching/unloading chamber (See Figure 3).
