Bluewater Thermal Solutions performs tool steel and stainless steel heat treatments in vacuum furnaces in several locations across North America. Tool steels and stainless steels are heat-treated in a vacuum and then can be quenched in high-pressure inert nitrogen gas if rapid cooling is required. This allows the surface
We also offer fast, controlled cooling on large cross sections with high-pressure multi-gas quenching, increasing ductility, improving die life and reducing heat checking. We have multiple large-capacity vacuum furnaces with a variety of quench gases including nitrogen, argon, helium and hydrogen. We offer a wide range of
Mar 1, 2013 gases to be used. • A method to optimize the cooling sys- tem's available power. Most vacuum furnaces are designed to operate at maximum pressure for a specific gas type (nitrogen requirement in many heat-treating facili- ties, these issues are allows the cooling system of the furnace to operate at the
Feb 10, 2015 A vacuum furnace is a type of furnace that can heat materials, typically metals, to very high temperatures and carry out processes such as brazing, sintering
Aug 6, 2016 With this need for heat treatment, the AM process necessitates the use of precise heat-treating systems that are capable of meeting specific criteria such as heating/cooling uniformity, temperature range, purity of atmosphere (gas) and vacuum level. Batch furnaces with either vacuum or a protective
traditional gas-fired furnace technology. In addition, more demanding quality requirements for high temperature processing, such as that imposed by the aerospace industry, have pressured the heat treat industry for continuously improved reliability and repeatability. Electric vacuum furnaces can provide this level of quality.
Oct 29, 2012 Heat-treating furnace equipment can further be divided into furnaces (atmosphere & vacuum), ovens and applied energy methods (flame, induction, laser). . Today, sufficiently clean gases are available for cooling in gas with impurity levels typically in 2 ppm of oxygen and 5-10 ppm of water (by volume)
This furnace offers great flexibility, having the ability to heat treat low, medium and high carbon steels, alloy steels, tool steels and stainless steel materials. It consists of a Programmable controls provide tailored thermal profiles including three modes of cooling - oil quench, gas cooling (above oil) and vacuum cooling.
Cooling Methods and Rates. Three basic means of cooling the workload of a vacuum furnace. Vacuum cooling,; Static cooling, and; Forced cooling. Three methods used to increase the rate of heat removal. Increase the mass flow of the gas (i.e., gas velocity),; Increase gas pressure and,; Use a gas with a higher thermal
There are several ways of achieving fast sample cooling in a furnace or oven: Moving the sample into a cool area; Movable insulation panels (manual or automatic); Ambient air blown into furnace or oven; Ambient air blown around inert gas retort; Cycling of inert gas atmosphere through a water cooled heat exchanger.
