Gas Quenching and Inerting | Praxair, Inc. A nitrogen or argon controlled atmosphere is most commonly used for this application. As nitrogen or argon is introduced into a furnace, the risk for oxidation of the component parts being heat-treated is reduced.

gas is to control the firing atmosphere, the size of the furnace is the first consideration. If the furnace is 0.2 cubic feet in volume and the flow meter is set on 1 SCFH, the atmosphere of the furnace will be changed 5 times per hour at room temperature (every 12 minutes). If, however, the furnace is over 1000F, the room temperature gas will
Inert atmospheres of nitrogen, argon, hydrogen and dissociated ammonia are common choices for controlled atmosphere brazing. Argon is more inert than nitrogen and therefore provides more control, but it is generally more expensive. The process temperature can also affects the performance of the gas chosen; nitrogen is often an economical choice

Alibaba.com offers 886 inert atmosphere furnaces products. About 69% of these are laboratory heating equipments, 15% are industrial furnace, and 7% are reactors. A wide variety of inert atmosphere furnaces options are available to you, such as free samples.
Nitrogen Generator for Blanketing (Covering) Gas: A term used to describe an inert gas such as nitrogen or argon introduced into a furnace to prevent oxidation of the component parts being heat-treated. The flowrate and pressure of the atmosphere and the equipment type (i.e. gas-tight construction) must be sufficient to limit the influx of air.
Custom High-Temperature Vacuum Furnaces Controlled & Inert Atmosphere Furnaces from Sentro Tech. Sentro Tech is a leading manufacturer of custom high-temperature vacuum furnaces and controlled atmosphere furnaces. These combined furnaces allow you to alter atmospheric conditions during a single firing cycle.
But an electric furnace will hopefully allow me to go a little more by the book for other heat treating, I have a thremocouple in my gas forge but the heat is not very even through the forge so I have to babysit it and compare the colour of the thermocouple to the colour of the pieces being heat treated.
201698Electric furnaces are oxidising atmospheres. You can get electric kilns that can have argon pumped through them to give an inert atmosphere but they tend to be rather pricey. Gas kilns can be reducing, oxidising or inert depending upon how the gas/air vents are set. you can turn an electric kiln into a reducing or inert
Guest Post: Atmosphere Furnaces & Temperature Uniformity (Part 2) [email protected] November 2, 2017 Nate Sroka, Mechanical Design Engineer As a Mechanical Design Engineer, Nate Sroka focuses on the mechanical design of atmosphere heat-treating systems.
Atmosphere Furnaces by Bionics Scientific are designed and manufactured to accommodate wide processing areas where inert atmosphere is required to protect heating samples that are prone to oxidation. Typical applications, where these units are employed are bonding, curing and heat treating.
improving furnace uniformity (Figure 4). In order to improve the wax collection and speed up debind-ing time, an argon sweepgas is used as a carrier gas. Because of the added gas load, vacuum levels of 10-1 torr are no longer possible. The system introduces a measured flow of inert gas into the chamber which diffuses into the graphite

Gases One of the main components of the atmosphere furnace is the correct mixture of gases. The precise measurement of each gas is essential to the success of your project. You can use a separate chamber to mix the gases, which are then pumped into the furnace chamber where the work will be completed when they are done mixing.
