Abstract:

A method for dispensing a compressed gas for reducing the amount of residual gas in dispensing station storage vessels before refilling is required. The method comprises transferring compressed gas into receiving vessels in a first series of fill-ups where each of the receiving vessels receive compressed gas from a first mobile storage device and subsequently from a second mobile storage device, transporting the first mobile storage device to a refilling station after the first mobile storage device has been depleted to a selected depletion level, refilling the first mobile storage device at the refilling station, and transferring compressed gas into receiving vessels in a second series of fill-ups where each of the receiving vessels receive compressed gas from the second mobile storage device and one or more of the first mobile storage device after refilling and a third mobile storage device.

Abstract:

An improved process for producing nitrogen-based atmospheres suitable for annealing ferrous metals and alloys, brazing metals, sintering metal and ceramic powders, and sealing glass to metals from non-cryogenically generated nitrogen is presented. These atmospheres are produced by 1) humidifying non-cryogenically generated nitrogen containing less than 5. 0 vol. % residual oxygen, 2) mixing it with a specified amount of a hydrocarbon gas, 3) feeding the gaseous mixture into the heating zone of a furnace through a diffuser, and 4) converting in-situ the residual oxygen and moisture present in it to a mixture of carbon dioxide, carbon monoxide, moisture, and/or hydrogen. The key features of the present invention include a) humidifying the feed gas prior to introducing it into the heating zone of a furnace operated above about 800. degree. C. and b) using enough amount of a hydrocarbon gas to facilitate in-situ conversion of residual oxygen and moisture present in the feed gas to a mixture of carbon dioxide, carbon monoxide, moisture, and hydrogen in the heating zone of a furnace.

Abstract:

An improved process for producing high-moisture containing nitrogen-based atmospheres suitable for oxide and decarburize annealing of carbon steels from non-cryogenically generated nitrogen is presented. These nitrogen-based atmospheres are produced by 1) mixing non-cryogenically generated nitrogen containing less than 5. 0 vol. % residual oxygen with a specified amount of hydrogen, 2) humidifying the gaseous feed mixture, 3) feeding the gaseous mixture into the heating zone of a furnace through a diffuser, and 4) converting in-situ the residual oxygen present in it to moisture. According to the present invention, the total amount of hydrogen required for producing suitable atmospheres can be minimized by simultaneously humidifying the feed gas and controlling the residual oxygen level in it. The key features of the present invention include a) humidifying the feed gas prior to introducing it into the heating zone of a furnace operated above about 600. degree. C. , b) selecting the level of residual oxygen in the feed gas in such a way that it minimizes hydrogen consumption, and c) using enough amount of hydrogen to convert completely the residual oxygen present in the feed gas to moisture and to maintain pH. sub. 2 /pH. sub.

International Classification:

C21D 100

US Classification:

148208

Abstract:

A process for generating in-situ low-cost atmospheres suitable for annealing and heat treating ferrous and non-ferrous metals and alloys, brazing metals, sealing glass to metals, and sintering metal and ceramic powders in a continuous furnace from non-cryogenically produced nitrogen containing up to 5% residual oxygen is presented. The disclosed process involves mixing nitrogen gas containing residual oxygen with a predetermined amount of a hydrocarbon gas, feeding the gaseous mixture through a nonconventional device into the hot zone of a continuous heat treating furnace, converting residual oxygen to an acceptable form such as a mixture of moisture and carbon dioxide, a mixture of moisture, hydrogen, carbon monoxide, and carbon dioxide, or a mixture of carbon monoxide, moisture, and hydrogen, and using the resultant gaseous mixture for annealing and heat treating metals and alloys, brazing metals, sintering metal and ceramic powders, and sealing glass to metals.

US Classification:

228220

Abstract:

The present invention discloses a novel, moisture-free atmosphere for brazing carbon steels that provides good braze flow and brazed joint quality with minimum or no formation of soot on brazed joints. According to the present invention, carbon steels are brazed in continuous furnaces using a moisture-free atmosphere containing a mixture of three gases including nitrogen, hydrogen, and carbon dioxide. The key features of the invention involve (1) formation of moisture, which is needed to facilitate braze flow and to minimize formation of soot on brazed joints, in-situ in the heating zone of the furnace by the reaction between hydrogen and carbon dioxide and (2) reduction in the overall amount of a reducing gas required for brazing carbon steels by keeping moisture out of the cooling zone. The use of a moisture-free three gas atmosphere has been unexpectedly found to (1) eliminate the need of an expensive and difficult to control external humidification system, (2) provide flexibility in adjusting moisture content of the atmosphere in the heating zone of the furnace simply by adjusting the flow rate of hydrogen or carbon dioxide or both, and (3) facilitate rapid conditioning of the furnace by keeping moisture out of the cooling zone. The moisture-free atmosphere has also been unexpectedly found to provide good braze flow, fillet formation, and brazed joint quality while minimizing or eliminating formation of soot on brazed joints.
