Leak Rates, Leak Detection and Leak Repair A common problem experienced by almost every vacuum user is that, over time, leaks develop that are both damaging to product quality and to furnace internal components. In extreme cases, the problem is obvious: the furnace will not pump down and/or the hot zone (or heating elements) shows obvious signs of oxidation.
The Basic Principles of an Electrode Regulation System The main physical principle of an electric arc furnace is the transfer of energy from the electricity line to the furnace through heat radiation and conduction generated by an electric arc.

Eddy Current Verification of Heat-Treat Processes: An Integral Part of Modern Manufacturing Metallurgists and heat-treat professionals have traditionally used a small number of parts for destructive testing to verify proper heat-treat processes. In today’s competitive manufacturing environment, sample destructive testing alone is not sufficient to ensure zero-defect policies.
Unifrax I LLC The Anchor-Loc 3 insulating fiber module is designed to meet a wide range of application requirements in many types of heat-processing vessels.
Shale Natural Gas Opportunities A recent conference in Pittsburgh, sponsored by Steel Business Briefing (SBB), brought to light some of the many opportunities available to our industry as a result of recent shale natural gas discoveries.
