Single PLC insulation two-seater annealing furnace control

Device description annealing is a steel or all kinds of metal machinery parts of heating to proper temperature, heat preservation for a period of time, and then slowly cooling, can get close to equilibrium heat treatment process of the organization. Its purpose is to refine the organization, to reduce the hardness, the improvement of mechanical machining performance and remove the internal stress. In the machinery manufacturing industry, annealing is often used in machining manufacturing process, prepare heat treatment process. Strong convective electric heating bell type bright annealing blue stoves is mainly suitable for brass, bronze, copper strip, copper belt, all kinds of precision copper pipe, coinage, soft magnetic materials, precision strip steel, composite strip and hard magnetic alloy, copper alloy wire, standard parts, materials, stainless steel belt and so on dozens of different materials. The biggest single clock cover furnace charge diameter 3. 2 m, loading height up to 4 m, the largest of 80 t of furnace charging. Considering the small metal processing enterprises without gas source, coal source, so this furnace using resistance with heating mode, compare with the bell type annealing furnace burning gas operation cost is relatively high, relatively longer production cycle. However, its configuration is simple, reliable operation, convenient maintenance, annealing temperature can be set in different stages of the process, can satisfy all kinds of metal annealing needs. With one set of the electric heating bell type annealing furnace control system independent double furnace heating annealing furnace, furnace itself USES the new light energy saving material, structure design is reasonable, the heat preservation effect is good, when the resistance with temperature of 1000 ℃, the heat shield shell just add 40 ℃ ambient temperature. Compartment protection using nitrogen hydrogen gas, the annealing is material in the condition of high temperature annealing without oxidation and decarburization. The vacuum system to save a lot of protective gas and electric energy consumption. Control system USES a single set of Siemens S7 - 200 series PLC controller automatic control of two sets of furnace temperature, heat preservation, cooling process, the high sensitivity of the thermocouple, obtained the temperature of the furnace cover and inner cover, according to the process of heating and heat preservation of temperature PID adjusting the working state of the heater and the heating frequency, to ensure that the heat preservation temperature constant, and is equipped with 8 inch touch screen, can the vivid image of each of the furnace temperature, heat preservation, cooling process implemented comprehensive control and management, production of qualified products provide a reliable guarantee. Characteristics of the equipment, using a single set of Siemens S7-1 200 independent control of PLC controller double stove electric heating bell type annealing furnace for heating, insulation and cooling at the same time, the controller is small in size, price cheap, controller of a complete set of the price is in 8000 yuan or so, control precision is high; 2, the whole equipment adopts full automatic control, the user as long as according to the technological requirements set by the touch screen after each stage of temperature and holding time, open the heating switch, fan, cooling fan, heater, heat will automatically according to the program is running; 3, the three sections of thermal control technology, the user can set three different temperature according to process requirements, in order to restore the annealing material in different temperature under different protective atmosphere of holding a predetermined time; 4, using high sensitivity of the thermocouple acquisition furnace cover, and the temperature of the inner cover, according to the process of heating and heat preservation of temperature PID adjusting the working state of the heater and the heating frequency, the thermal insulation of high precision, the effect is good, to cover the actual temperature and set temperature error in + 1 - 3℃； 5, the whole set the temperature of the node in the annealing process and equipment failure will prompt the user in the form of a buzzer alarm, and provide relevant alarm information; 6, with careful protection, chain needs in vacuum annealing furnace, stop all the heaters and ventilation equipment shall be for vacuum operation, did not reach the standard gas pressure in the inner cover, can't restart the heater and ventilation equipment; 7, resistance band heater control and solid state relay contactor control in two ways, both to ensure that the heating temperature rapid ascension, and avoid the heat preservation temperature fluctuate frequently. More than three, annealing furnace section of insulation control set curve in the annealing furnace in the period of thermal control set curve, divided into housing temperature curve and the inner cover temperature curve, in addition to being able to set the three sections of the temperature of the thermal insulation and heat preservation time, need to set the secondary pumping air into vacuum state, filling nitrogen, hydrogen, hydrogen filling, filling steam, the temperature of the oven, when the temperature of the inner cover is to reach the corresponding temperature, alarm prompt the user for corresponding operation system. Four, the main operating images of two-seater annealing furnace control system configuration 1. Siemens S7 - The 200 series CPU226, DC24V power supply, 24 di / 16 do; 2. Siemens S7 - The 200 series EM231, 4 channel TC temperature input; 3. Siemens S7 - The 200 series EM232, 2 channel voltage output; 4. Siemens S7 - 200 series EM222, 8 do relay output; 5. 8 inch touch screen, TH865 - M。
