Steelworks tensile test furnace
The know-how of ISB Technologies allows us to provide a perfectly adapted answer to your needs. Here we present our steelworks tensile test furnace, a model intended for industrial production.
THE CHARACTERISTICS OF THE FURNACE OF STEELWOKS TENSILE TEST
The heating temperatures of the test tubes range from 50°C to 900°C. The display accuracy of the temperature measurement is of the order of +/- 1°C for all temperatures (regulator, recorder or measurement lines).
The temperature tolerance on the product is ±3°C if T<=600°C, and ±4°C if T>600°C. The temperature dispersion tolerance over the entire height of the calibrated body of the specimen is ±3°C.
There is no temperature drift outside of these accepted tolerances while holding the specimen at temperature. This maintenance can last up to 30 minutes, regardless of the set temperature. Overheating outside of these tolerances is prohibited.
THE IRC OVEN
The main body of the oven is made of aluminum cut in the mass, which allows hydraulic cooling of the whole, by means of a water inlet/outlet. A multiple socket allows the oven to be electrically disconnected. Compressed air taps are used to cool the lamp connections.
The lamps are divided into several zones, in order to have the best possible homogeneity .
This counteracts the chimney effect created by the verticality of the traction medium. But also to keep the same temperature over the entire specimen despite the rapid diffusion of the temperature by the specimen holder.
The electrical box
An electrical box receives the power gradation by thyristor block, as well as all the equipment for the control, protection, and regulation of the furnace.
Three dimmers, in phase angle or advanced syncopated mode, each control one zone.
Each of these dimmers is controlled by a regulation loop making it possible to adjust the heating power of each zone.
– A regulator installed, used as an acquisition center for temperatures
– Three PID type regulators, controlling the three power gradators.
Water cooling is controlled by a latching button. This circuit is independent and the heating cannot be started until it is not engaged. The cooling of the connections by compressed air is activated at the same time as the heating.
