In materials science, quenching is the rapid cooling of a workpiece in water, gas, oil, polymer, air, or other fluids to obtain certain material properties. A type of heat treating , quenching prevents undesired low-temperature processes, such as phase transformations, from occurring.
primary and secondary heat recovery with quench; a dilution steam recycle system between the furnaces and the quench system; primary compression of the cracked gas (3 stages of compression); hydrogen sulfide and carbon dioxide removal (acid gas removal); secondary compression (1 or 2 stages); drying of the cracked gas; cryogenic treatment;
The building was heated by steam and equipped with a system of waterworks for quenching fires. It employmed 50 to 60 people directly, and used 450 lb (200 kg) of Canadian wool daily. The mill bought the latest cards, spinning machines, twisters, and Knitting machines built by Davis and Furber in Northampton, Massachusetts. The rebuilding and re ...
The Ohio Oil and Gas Land Management Commission granted the mineral rights to several oil and gas companies, allowing them to frack for oil and gas under land owned by the Ohio Department of ...
Martempering is also known as stepped quenching or interrupted quenching. In this process, steel is heated above the upper critical point (above the transformation range) and then quenched in a hot-oil, molten-salt, or molten-lead bath kept at a temperature of 150-300 °C. The workpiece is held at this temperature above martensite start (Ms ...
Quaker Houghton is an American chemical company that was founded in 1918. It is headquartered in Conshohocken, Pennsylvania.With its global presence in 21 countries and 35 locations worldwide, the company has over 50% of net sales outside of the United States. [1]
Quench polish quench (QPQ) is a specialized type of nitrocarburizing case hardening that increases corrosion resistance. It is sometimes known by the brand name of Tufftride, Tenifer or Melonite. [1] Three steps are involved: nitrocarburize ("quench"), polish, and post-oxidize ("quench"). [2]
A similar process is the trademarked "Nu-Tride" process, also known incorrectly as the "Kolene" process (which is the company's name), includes a preheat and an intermediate quench cycle. The intermediate quench is an oxidizing salt bath at 400 °C (752 °F). This quench is held for 5 to 20 minutes before the final quenching to room temperature.
