??? Xinxiang Sun Moon Star Furnace Co., Ltd. is a modern box-type resistance furnace manufacturers, with high-end technology and equipment as well as new entrants receive significant technical concepts, in each stage of production are strict checks to ensure the production of the box resistance furnace after passing the factory. ??? Box-type resistance furnace is heating, heat treatment of a special device, in accordance with the furnace temperature distribution along the length of the furnace body consists mainly of the initial warm-up segment, the mid-section and uniform heating of heat segment. ??? The material is pre-filled, low temperature, in the warm-up phase, the main role of this part of the heat of the furnace gas is carried out within the full advantage of, which can improve the thermal efficiency of the heat treatment furnace largely box. ??? The main role of box-type resistance furnace heating segment in the supply of heat, then the higher the internal temperature of the furnace, to achieve fast and efficient heat treatment has a positive role in promoting. ???
