The tube heating furnace manufacturer tells you how to distinguish the resistance furnace of A

Suzhou Jiuwei Electric Furnace Equipment Co., Ltd. has special insights on how to distinguish the resistance furnace of A

When the clock circuit is working normally, the thermocouple sensor measures the temperature signal of the resistance furnace of the controlled object, through the cold end temperature compensation, linearization, amplification and digital processing of the signal adjustment circuit, it is sent to the stm single-chip microcomputer, and The given value of the system is compared, the single-chip microcomputer makes a judgment according to the inevitable control algorithm and sends a control signal to the execution module. Through the control of the power on and off time of the resistance wire of the resistance furnace, the purpose of controlling the temperature of the resistance furnace is achieved. The pulse width modulated power signal from the secondary winding is subjected to high-frequency rectification and filtering by the uf and s capacitors to obtain a voltage of about v. The furnace shell is a cylindrical furnace body welded by section steel and steel plate. The furnace lining is made of refractory bricks, and the refractory bricks and the furnace shell are filled with insulation materials.

The end of the max data reading process The author first designed a resistance furnace intelligent temperature controller based on stm single-chip microcomputer. However, additional functions such as display, temperature setting, etc. need to be added, and the response speed is slow. The system’s other electrical design data memory expansion at9c has byte data ram in the chip. After the system loses power, the main information such as system parameters and temperature curves will be lost. If the power is unexpectedly lost, improper handling will interrupt the production process, causing The production failed. Focusing on 0 single chip microcomputer, adopting temperature transmitter bridge circuit and solid state relay temperature control circuit to realize automatic control of electric furnace temperature. In the design process, the software design and development of the predecessors were the first to make the system function modular and to be simulated separately through the proteus software. After the function was realized, the hardware was comprehensively designed, and the parameters of each device were repeatedly demonstrated and tested to make it impossible. Variable operation finally makes this system realize constant temperature control.

In the traditional resistance furnace temperature controller, the electricity is complicated and complicated, and the control accuracy and invariance are not very ideal. 496 voltage; when the internal reference source is disabled, it can be input. For places that need to appreciate the temperature change at any time, this method will consume a lot of manpower and material resources, and the temperature value that changes quickly cannot be measured in real time, and the end is not safe. , Linear voltage regulator device l (+v/ma, 9l(v/ma, lm(+v/a. (The content of any storage unit can be verified by reading instructions. The furnace roof electric heating system energy-saving refreshing eliminates the furnace roof beam or The brick furnace arch structure is changed to an action-type full-fiber furnace cover structure (steel structure furnace cover + pre-compressed fiber block, the furnace top electric heating element is suspended and fixed by insulating porcelain pipes, and the electric heating element is a drawable resistance wire structure. Furnace The power is kw, and the three-phase star connection method can be used to buy the individual. The three-phase delta connection method can also be used. The over-temperature control system should be suitable. The bff8 has the characteristics of simple line, constant function and small size, temperature measurement scale ~ +, inherent temperature measurement resolution The door of small and medium-sized electric furnaces can be opened and closed with counterweight and manual assembly. Generally, there are sand sealing grooves at the lower part, and some furnace doors are also equipped with sand sealing grooves on the upper side to ensure excellent sealing. When the furnace door is blocked, use pressure Tight assembly makes the furnace door closely contact the door frame to reduce air leakage.

Do not exceed the peak temperature of the resistance furnace during use. As a control signal, what is transmitted is a signal, not energy. 890 focuses on matters. There is a channel multiplex switch inside, which can latch the decoded signal according to the address code, and only select one of the analog input signals for a/d conversion.

The personnel in the laboratory adjust the voltage of the resistance furnace according to the firing system of the material to realize the temperature control of the resistance furnace. For example, the panel name is listed in. This structure greatly improves the code efficiency, and has a data throughput rate that is twice that of the popular CSI controller.
