The uniformity of the temperature distribution is very important to the sintering process of the product, the smaller the temperature deviation of each position in the furnace is, the smaller the size and physical property deviation of the sintered product is, the higher the product percent of pass is, and the higher the production efficiency is. However, in the pressure sintering process, the high temperature and high pressure atmosphere can cause the gas to move vigorously, so that the high temperature gas rises, the low temperature gas falls, and the phenomenon that the temperature of the upper region in the furnace is high and the temperature of the lower region is low is further presented.
The existing sintering furnace heating device comprises electrodes, heating rods and flow guide strips, the whole heating device is formed by connecting the flow guide strips at two ends of the heating rods into a whole to form a cage-shaped structure, the electrodes are connected to the flow guide strips at one end, and when the electrodes are electrified, the electrodes transmit current to the heating rods through the flow guide strips, so that the heating rods are electrified to generate heat.

In order to reduce the temperature difference between the upper area and the lower area in the furnace, in the related technology, the interior of the furnace is divided into a left area, a right area and a lower area, the heating device is correspondingly divided into three heating modules, the three heating modules are respectively positioned in the left area, the right area and the lower area, the three heating modules independently heat through respective electrodes and heating rods, and the electrodes in the left area and the right area are concentrated at the lowest part of the areas and are positioned near the furnace bottom so as to improve the temperature of the lower area in the furnace and further reduce the temperature difference between the upper area and the lower area in the furnace. However, the electrode arrangement structure in the furnace has the following technical problems in the actual use process:
1. the three heating modules are arranged in the furnace and can independently heat the left, right and lower areas in the furnace, but the temperature of each area in the furnace cannot be accurately controlled due to the lack of the modules such as independent temperature measurement and independent temperature control of the three heating modules in the furnace, so that the temperature difference of each area in the furnace is difficult to control within a preset temperature range, and the temperature in the furnace is uniformly distributed;
2. because the electrodes in the left area and the right area are concentrated at the lowest part of the area, all the heating rods in the left area and the right area are positioned above the electrodes, when the electrodes are electrified, the electrodes transmit current to the heating rods near the electrodes through the guide bars, the heating rods near the electrodes divide part of the current to the adjacent heating rods, and the current passing through the heating rods in the same area (namely the left area or the right area) is seriously unbalanced due to the sequential transmission, wherein the larger the current passing through the heating rods near the electrodes is, the larger the loss of the heating rods is, and the service life of the heating rods near the electrodes is greatly shortened.
