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.
Partial Pressure Vacuum Processing – Part II: Applications
This article is based on a presentation at the Furnaces North America ’96 Conference, held in Dearborn, MI, September 24-26, 1996 and sponsored by Industrial Heating. In part two, partial pressure vacuum processing cycles for different materials are reviewed. Information regarding the evaporation of base metals and reactive processing was presented in the September ’97 issue of Industrial Heating.
Partial Pressure Vacuum Processing – Part I
This article is based on a presentation at the Furnaces North America ’96 Conference, sponsored by Industrial Heating. In the first part of this two-part series on partial pressure processing, techniques for controlling evaporation of base materials and reactive processing are discussed. In Part II, actual applications for production operations will be presented with full process cycles and descriptions.
The Advantages of Ion Nitriding Gears
Ion Nitriding gears has the potential to eliminate the need for expensive post-heat treatment operations. The advantages of ion nitriding compared to conventional hardening methods are presented from the point of view of a custom gear shop executive and a heat treater.
Vacuum Brazing: A Three in One Process that Provides Efficiency
Different metal joining processes each have advantages and applications for which they are best suited. An often overlooked capability of vacuum brazing is the simultaneous combining of three metal treatments in one process: bonding, cleaning and heat treating.
Vacuum Heat Treating for M2 High Speed and D2 Tool Steels
A series of large cross section D2 and M2 tool steels have been obtained and cross cut prior to heat treatment. Similar heat treating, time and temperatures, will be run in a salt bath furnace and a vacuum furnace. All parts will be tracked for process temperature via deep imbedded thermocouples. Data reported, including metallurgical results, for an independent laboratory.
Energy Dominates in Job Costing
Job costing can sometimes be a tedious task, however, it is a necessity if a business is to understand its true costs and predict its profits. Using a vacuum anneal heat treating cycle, as an example, costs can be identified by category, permitting a total cost to be calculated for the job. The seven specific topics covered are the initial cost of equipment, electric utilities, labor, process gases, fixturing, water cooling systems and maintenance.
