Horizontal Tempering Plants

Because the design of drop-bottom furnaces limits their maximum temperature to 600 °C, different plant concepts are needed to temper materials, such as steel, where much higher temperatures are required. 

For these processes, horizontal chamber furnaces, which are loaded from the front by a two-axis manipulator, are suitable. This type of plant is characterized by a low construction height and a low level of wear and tear, as the movement technology is in the hot zone only for a short time. Depending on the charge weight and dimensions, these systems allows quench delay times of seven seconds. Consequently, in many cases, horizontal tempering plants with a forced convection furnace are also very good for heat treatment of aluminum. 

Nabertherm offers a wide range of standard sizes on which manual, semi or fully automatic horizontal tempering plants can be developed.

• Working temperature range between 80 °C and 1300 °C
• Quench tank with circulation, fresh water cooling, level control and temperature monitoring
• Two-axis manipulator with fork for semi-automatic charging, removing and quenching the charge
• Over-temperature limiter with adjustable cutout temperature as temperature limiter to protect the furnace and load
• Exclusive use of insulation materials without categorization according to EC Regulation No 1272/2008 (CLP). This explicitly means that alumino silicate wool, also known as “refractory ceramic fiber” (RCF), which is classified and possibly carcinogenic, is not used.
• Defined application within the constraints of the operating instructions
• Siemens S7 PLC controls with touchpanel as operating interface
• Electrically heated
