Heating System

Permanent And Complete Control With Four -Section - Nine - Point Controlling

The container and the liner are UNDER COMPLETE CONTROL from total of 9 points as front, rear, front-bottom, front-top, 2 at each four Thermocouple and 1 at safety thermocouple. Section temperature control thermocouples can carry out measurement from two points, 1 point controls the liner temperature while the second point controls the resistance temperature which causes the resistance to be used for long terms. Cartridge heaters are produced both as one section and as controlled from multiple sections.

Section Controlling Containers

Influences of external heating on steel are known today. Outside-in heating irredeemably damages the container. Temperature differences especially on the outer and inner parts of container mantle cause hairline cracks on the surface and reduces the impact of heat treating. Over-energy that is consumed to keep the liner at the desired heat for the externally heated containers independently poses a problem as well. When we consider that we separated the container into two main sections (fair average) as front (Die side) and rear (Stem side) and separated these two sections into another two sections as upper and lower, it is obvious that the container has four heat sections that must be controlled. We see that the front section heat where the billet is in press is always high. At the same time, it is possible to see heat accumulations on the upper part as well, namely high temperatures. Therefore, four sections of the container must be checked separately for homogeneous temperature. It is a must to check these four sections separately after the container reaches the operating temperature. Thus, the temperature differences emerging among these sections and energy consumption will be eliminated. The heating method in question is provided by cartridge heaters that are placed into the container mantle. One of the most important reasons for the preference of resistance is the fact that it is easy to maintain and it can be parallel connected.
