The bending and tempering process in brief. Modern horizontal bending and tempering lines commonly operate like this: The flat glass is first heated to over 630 °C − until red hot. Once heated, the glass is moved within the furnace into the bending station, where it is bent to its target radius.
The specified austenitizing or tempering time at temperature begins when the thermocouple reaches the desired set point temperature. An acceptable alternative to a separate heat sink is to imbed the temperature sensing tip of the thermocouple at least 1 inch below the surface into one of the production parts' heaviest cross section.
Heat Treatment of Plain Carbon and LowAlloy Steels: Eﬀects on Macroscopic Mechanical Properties. 1 Background and Objectives Iron is one of the oldest known metals, and carbon is the cheapest and most eﬀective alloying element for hardening iron. IronCarbon alloys are known as "carbon steels"
Oct 29, 2012 Heat-treating furnace equipment can further be divided into furnaces (atmosphere & vacuum), ovens and applied energy methods (flame, induction, laser). When an air atmosphere is used, such as in a low temperature tempering operation, the final condition of the material's surface (or "skin") is not
We also offer vacuum brazing furnaces and ovens, optical coating systems, thin film disposition sputtering systems and atmospheric enclosures, commonly known as glove boxes. We strive to create the best vacuum tempering furnaces and heat treating equipment possible which means high quality and cost effective products.

It should remain at tempering temperature for as long as you can maintain it or up to an hour. If your tempering block is fairly large just let it and the blade both cool together. Tempering temperature varies with the variety of steel. It can be as low as 350°F and as high as 1300°F. Most steels are tempered in the 500 to 600°F range.

Tempering Furnaces.-- In tempering furnaces the only really important consideration is to insure that the furnace is so built as to heat the bath uniformly throughout. It is doubtful if there can be found a tempering furnace on the market that will fill this requirement entirely, although many give good results in general.
Trolley High Temperature Furnaces Low Temperature Vacuum Brazing Furnace With The Strongest Furnace Shell In The World;<
A tempering furnace at the later stage of the carburizing and hardening process ensures uniform temperature distribution by hot air circulation in the furnace. This is achieved by means of a large capacity fan and soaking plates. Two series are available for high temperature applications and low temperature applications. Steam Tempering Furnace
As tempering is the process of reheating a hardened steel up to a temperature, maximum A1, it is a low temperature process. It can be performed in a: (a) Oil-bath furnace (b) Salt bath furnace (c) Lead bath (d) Forced-air circulation furnace.
