The box-type resistance furnace has many years of design and manufacturing experience and has a number of design patents. It is specially used for chemical element analysis and high temperature heat treatment of small steel parts such as quenching, annealing and tempering in laboratories of industrial and mining enterprises, colleges and universities, and scientific research units. ; It can also be used for high temperature heating such as sintering, dissolution and analysis of metals, stoneware and ceramics. Features: A. Humanized design: 1. The unique furnace door design makes the operation of opening the door safe and easy to ensure that the hot gas inside the furnace does not leak out. 2. Microcomputer PID controller, easy to operate, accurate, reliable and safe temperature control. 3. Corrosion-resistant and lightweight furnace to ensure durability. (Any choice of refractory brick furnace or ceramic fiber furnace). 4. Excellent door seal minimizes heat loss and increases the uniformity of temperature in the furnace. 5. Programmable controller, 30 sections of programs, each section can be set to heat up or stay, and provide programmed temperature, time, heating power cycle. (Programmable box type resistance furnace has this function) 6. Multi-segment programmable control can simplify the complicated test process and realize automatic control and operation. The inner tank of the furnace door and the panel of the box body are made of stainless steel, which has the characteristics of corrosion resistance and high temperature inconvenience. (Programmable box type resistance furnace has this function) B. Safety function: 1. Only need to open the furnace door during operation, and the furnace door safety switch will automatically cut off the heating power to ensure the safety of the operator. 2. There are multiple safety protection measures such as overcurrent, overvoltage, overheating, etc., to ensure the safe use of electric furnaces. 3. Choose ceramic fiberboard as heat insulation material, which has the characteristics of good heat insulation effect and low surface temperature of the box shell. 3. Furnace selection (users can choose according to their needs): 1. The operating fiber furnace (C series) has the characteristics of light weight, fast heating speed, energy saving and time saving. It can meet the requirements of various fast sintering and is an upgraded product of the traditional furnace. 2. Refractory brick furnace (A series) adopts traditional refractory materials, which has the characteristics of wide application range, long life and high cost performance.
