One Minute Mentor: High performance line with hydrogen quenching

For stainless martensitic grades and carbon steel up to certain thickness, the two-stage molten metal quenching is successfully converted into hydrogen quenching with big advantages in quality, including oxide-free and lead-free surfaces. Cooling gradients of up to 300 K/s are possible. Martensitic chromium steels with 13% Cr and 0.2 to 0.4% C are used to manufacture various stainless steel components, knives, and tools, as well as parts for the cutlery industry.

 

A special application for producing high-quality heavy-duty strapping band in bainitic condition is a line with high throughput and low-energy consumption. The steel grade AISI 1536/DIN EN 36Mn5 is usually preheated to approximately 400 °C (750 °F) in a compact two–stage molten metal quench, acting as the secondary winding of the transformer fed. The strip is raised to austenitizing temperature at 900 °C (1650 °F) and then quenched in the molten lead/bismuth. The thermal energy dissipated during quenching is used to preheat the incoming strip.

One Minute Mentor: High-Performance Line

The continuous heat treatment of tool steel is applied to low- or medium-alloyed carbon steel strips as well as martensitic stainless steels. The described lines produce high-quality strip with respect to uniform structure, flatness, and bright surface finish. High quenching rates are necessary, especially for plain carbon steels. Cooling gradients of up to 600 K/s are possible in a molten lead-bismuth quench. Because two-stage quenching technology provides considerable advantages over quenching in oil, this method has been adopted worldwide. It is also possible to achieve isothermal transformation to bainite and pearlite using a molten metal quench, so this type of hardening and tempering line is extremely versatile.

The configuration of a high-performance line involves an entry and exit section of the strip handling equipment. The hardening section consists of the austenitizing furnace, the molten metal quench or hydrogen quench, and a martensite cooler.
