Discover the world of heat treatment!
How to solve the non-linearity of the resistive value of the SiC heater with the power controller in the holding furnaces for die casting
All the advantages of a robust and performing vacuum oven control system thanks to the power resistors.
Find out how to achieve temperature uniformity of 1.5 ° C in a 3-zone metal heat treatment furnace with a multifunctional PID controller.
How in the cooling tunnel of a float glass plant the electronic power controller allows you to control the electric heaters based on the temperature profile and the cooling gradient.
Temperature adjustment and control are critical in heat treatment applications. The overcurrent fault protection (OFP) fuses are usually used to protect systems from breakdowns. But these fuses are very expensive because they involve very precise and repeatable melting energy.
Gefran has patented a new solution that guarantees savings in terms of cost of replacement parts, labor, and down-time.
ISOCLIMA is the world’s leading producer of high-performance glass.
B.H.T. srl builds furnaces to temper curved and flat glass, and required an efficient application to manage a furnace with 520 temperature zones for a flat glass production plant.
Linn, a specialist in industrial furnaces, needed to setup an induction for melting tests on several metals (from platinum to iron). Induction furnaces are electrical furnaces in which the heat is applied by induction heating of metal. The advantage of an induction furnace is a clean, energy-efficient and well-controllable melting process compared to most other means of metal melting.
