The shell of the continuous tempering furnace is rectangular. The shell is made of steel plates and various types of steel. It is Huff-type, that is, the upper and lower furnace bodies can be separated, the middle is bolted, and the hearth can be separated. Fiber cotton is used as insulation material, and stainless steel Yuan steel is used as fixing nails. The lower furnace uses various refractory brick combined structures, and the heating elements are evenly distributed on the lower refractory bricks on the heating section and on the sides of the furnace lining cotton. A furnace tank is installed in the center of the furnace. The furnace tank is welded with stainless steel. A uniform reinforcement rib is welded on the outside of the furnace tank. A spiral reinforcement rib is welded on the inside of the furnace tank. The material is automatically advanced to the outlet, and a hopper is installed at the inlet. By adjusting the hopper gate, the quantity of the material can be adjusted. There are two sets of detachable supporting rollers at both ends of the furnace for easy replacement and maintenance. One group of supporting rollers can fix the rollers, and the other group can freely expand and contract the rollers in the furnace. The rolling mechanism is distributed in the lower part of the furnace body. The cycloidal pinwheel reducer is driven by the speed-regulating motor, and the drum is driven by the chain transmission. The control of the resistance furnace is controlled by a pid zero-cross trigger, and the power is adjusted by Guolong intelligent instrument. The size and power can be adjusted, and the three-phase current imbalance can also be adjusted. . The record is recorded by Dahua recording instrument. At the same time, Dahua recording instrument can also be used for the temperature monitoring of the furnace and the audible and visual alarm for the overheating of the resistance furnace. The resistance furnace is controlled by zones, each zone has a current, and the voltmeter shows phase loss. At the same time, the entire resistance furnace is equipped with a power main cabinet with the resistance furnace, and the main power control switch and fast fuse are set to facilitate the use and maintenance of the user.
