Development Experience in Low-Torr Range Vacuum Carburizing
Vacuum carburizing has become one of the hottest topics in the heat treat industry and the development of low-torr range carburization is an important advancement for metallurgical applications.
Calculating the Gas Flow Rate for Vacuum Carburization
A proposed technique of determining the actual required flow rate of the carburizing gas into a furnace to provide the necessary amount of carbon for a given work load.
Adding High Velocity to High Pressure Gas Quenching
When gas quenching, the minimizing of heat treat distortion is gears may be a matter of high pressure and high velocity. That’s what 91´«Ă˝ thinks, that’s why the heat treat company sends helium gas into its vacuum furnaces at more than 100mph.
High Gas Velocity: A New Frontier of Cooling Performance in Vacuum Furnaces
Because there are diminishing returns in cooling capacity by simply increasing quench-gas pressure, increasing gas velocity might be the answer to the problem.
Conserving Electric Power Part II
Examining electric power consumption in a heat treatment facility can be a challenge, especially when it is undertaken in an effort to reduce operating costs. Any effort in this direction is definitely worthwhile when the magnitude of today’s electric power pricing is taken in to account.
Conserving Electric Power Part I
This article is in part on “An Engineer’s View on how to conserve $ and electric power”, presented at the Metal Treating Institutes Furnaces North America, Las Vegas NV April 3-4, 2002. This article is part 1 of a two part series.
High Pressure Gas Quenching Typical Oil Hardening Grades of Steel
High pressure gas quenching has been identified as one of the most important advancements in recent developments of heat treating technology. Over the decades, an extensive amount of research and documentation has been published on the hardenability of water and oil hardening grades of steels. To date, there is relatively little or no information on the hardenability of oil hardening grades of steel quenched in a high pressure, gas environment.
Cryogenic Treatment Review
Claims for the benefits of cryogenic treatment abound. Research also abounds, but with differing conclusions. Yet, results have proven helpful, even dramatic, for the wear life of metal parts, dies and tooling applications after cryogenic treatment.
Power Factor Costs: How are They Affecting the Bottom Line?
This article discusses the concept of power factor and introduces a number of considerations for improving the control and consumption of power in thermal processing facilities.
Vacuum Pressure Quenching of Oil-Hardenable Materials
High pressure gas quenching has been identified as an important advancement in heat treating technology. While an abundance of docume ntation exists on the hardenability, mechanical properties, and microstructures of water and oil-hardening grades of steel, there is relatively little or no available information on the metallurgical properties that can be achieved when these materials are quenched in a high pressure gas environment.
