Troubleshooting Hydrogen Annealing of Steel Strip: Part 2

Mar 10, 2003 · The use of high thermal conductivity, low-density hydrogen at relatively high flow rates combined with the intense recirculation of the furnace atmosphere in high convection advanced bell type furnaces produces more consistent mechanical properties and better surface finish of the annealed products than those obtained for the materials annealed in conventional bell type furnaces using HNX (purified exothermic and nitrogen + 5-7% hydrogen) atmospheres.

Furnace atmospheres 1 Gas Carburizing and Carbonitriding

In the above reaction, carbon monoxide (CO) and hydrogen (H2) react so that carbon (C) is deposited on the surface and water vapour (H2O) is formed. A requirement is therefore that the furnace atmosphere must contain so much carbon monoxide and hydrogen that the carburizing process can proceed in a uniform and reproducable fashion. According H CO 2 H 2 C O

Sintering furnace atmosphere control and optimisation

For most continuous belt furnaces, an ideal atmosphere distribution consists of 20% wet or dry nitrogen introduced into the pre-heat zone, 60% nitrogen + hydrogen into the hot zone and 20% dry nitrogen into the cooling zone. This type of zoned atmosphere helps to minimise total gas flows and concentrates the hydrogen where it is most needed.

The actual sintering takes place in the high-heat sintering furnace under a hydrogen, or in some applications, a hydrogen-nitrogen atmosphere at temperatures above 2400 °F (1300 °C). Finally, the part goes through the cooling section, where cold water flows in a jacket surrounding the chamber and cools the parts before they exit the furnace into the outside air.

FAQ: What Is Hydrogen Furnace Brazing?

A: Hydrogen furnace brazing is a technique where brazing is accomplished in a pure hydrogen atmosphere without flux. This process is used for many alloys, including carbon steel, copper and stainless steel. Hydrogen reduces the metal oxide on the surface and allows the brazing filler metal to diffuse or wet in to the base metal.

Hydrogen Brazing | Wet or Dry | Altair Technologies USA

Hydrogen furnace brazing is also arguably the best method for brazing metals to metalized ceramics. Although Hydrogen brazing alloys and fillers do not use a flux, H 2 acts as a fluxing agent to reduce oxides and remove hydrocarbons. Many oxides, such as oxides of iron (steel), copper, nickel, etc., are easily reduced by Hydrogen, whereas many others, such as those of aluminum, titanium and beryllium, are very difficult to reduce.

FAQ: What Is Hydrogen Furnace Brazing?

Hydrogen furnace brazing is done in a pure dry hydrogen gas atmosphere at a slightly positive pressure. The brazing temperature is dependent on the base metal being joined and the filler metal used in the brazing process. The uniform heating in the furnace allows even complex shapes to be brazed with little distortion.
