Sep 12, 2012 · When the furnaces were up to the normal operating temperature, H 2 /N 2 mixed gas was introduced. Following some atmosphere-flow balancing work and within 24 hours of the H 2 /N 2 atmosphere being in the furnace, the dew-point measurements for furnaces #2 and #3 were substantially lower than those achieved with the previous exothermic generator
Finally, polymer matrix materials are applied onto the rovings and placed in a carbonizing kiln or furnace where the polymers are transformed into carbon in a non-oxidizing atmosphere. During carbonization, the products of organic polymer burn out and are vented from the furnace.
In the early stages of heating the furnace ramped to temperature using pressure rather than temperature control. At a pre-set temperature during the cycle a partial pressure of Hydrogen gas was introduced into the chamber. The reducing effect of this Hydrogen being beneficial to the sintering process.
A key heat-treat consideration is the creation of an atmosphere within the furnace that is neutral to the parts being processed. This can be done a number of ways and depends on the temperature of the process and the carbon content of the parts. Considerations in Heat Treatment Part One: Furnace Atmospheres

Molybdenum-wound hydrogen Atmosphere heat treat furnaces have become useful and necessary tools for both industry and research. For the manufacture of carbide tools and radio tubes, for wire drawing, metal sintering, brazing, heat treating and research, this furnace has found wide use. The necessity of a reducing and non-carbonizing atmosphere
Furnace Technology The hot wall principle In a chamber furnace a protection gas or vacuum tight retort (muffle) is inserted. Insulation and heating elements are sit-uated outside the retort, i.e. they are not exposed to the protection gas atmosphere (Fig. 1-3). For heating ele-ments and insulation the same material for the corresponding temperature
graphite sintering plate mould for vacuum furnace graphite sintering plate is made of high quality artificial graphite by mechanical processing. It is mainly used in all kinds of vacuum resistance furnace, carbon tube furnace, induction furnace,
Pyrolysis and Sintering processes are used to fill the ceramic matrix in between the fibers. The sintering process of ceramic composites doesn't require an oxygen free atmosphere, but tight temperature control and temperature uniformity inside the furnace for heating and cooling yield better results.

High vacuum furnaces and ovens, thin film disposition sputtering systems and glove boxes are just a few of the outstanding products provided by T-M Vacuum Products.
furnace and reaching the batch material, the metallurgic heat treatment, i.e. the phase in which the required properties are practically burnt into the metal, takes place under an€atmosphere of protective gas.€In some cases, it is sufficient to use nitrogen (N2) as the inert gas to prevent oxidation of the metal surface. However, de-
GAS STORAGE SYSTEM. In vacuum furnace applications where rapid gas quenching is required (for example, heat treating of air hardening tool steels or high-speed steel) it is important that the furnace chamber is filled very rapidly with an inert gas. It is also important that this gas is supplied to the furnace without contamination.

Vacuum Heat Treatment of Tools and Dies and other components of tool steel material like HSS, Hot Work Tool Steels, Cold Work Tool Steels, Martensitic Stainless Steels etc. which are gas quenchable are offered by ALD Dynatech through their MONOTHERM Single Chamber Vacuum Heat Treatment Furnaces with temperature
The Furnace Water Cooling Manifold consists of multiple circuits to adequately cool all the furnace parts and includes a strainer, pressure regulator, pressure gauge, water inlet and outlet manifold, a water flow switch as a visual water flow indicator with a flow interlock to protect the furnace in the event of a water flow failure.
Advantages of vacuum heat treatment (1) bright quenching can be realized. The workpiece below atmospheric pressure heating, not exposed to air, the surface will not change, when the vacuum furnace is pumped to 1 ~ 10-1Pa, the surface of the workpiece to achieve no decarburization, carburization purposes, so as to achieve the purpose of light quenching.
