The mechanical drive of the natural gas solution furnace adopts interlocking control

The mechanical transmission of the electric furnace adopts interlocking control, that is, after the furnace door is opened, the installation of the ventilation fan and the power supply of the heating element are automatically cut off. After the furnace door is opened in place, the ability to connect all the fan installation and the power supply of the heating element to prevent malfunctions and accidents caused by misoperation. The system has sound and light alarm performance. The temperature control system adopts PID zero-crossing to trigger the thyristor, and the smart meter controls the temperature. In addition, Shanghai Dahua Measuring Tool Factory's multi-point active recorder is used to record heat and over-temperature alarm to ensure that the work is not over-temperature. The temperature controller is also equipped with a communication port, which can communicate with the local computer to control the heat in the process. Master the parameters such as numerical value, preservation time, etc., by the local master computer opposite programming and management.

The main structure of the natural gas solution furnace:

The main structure includes: furnace body, furnace body steel bracket, detachable furnace roof, furnace lining, electric heating elements, cycle fan, air deflector, furnace bottom split furnace door, two-speed elevator structure, material rack, quenching tank, transportation It consists of feed truck, control system, power distribution cabinet/control cabinet, hydraulic system, etc. The frame of the furnace shell adopts section steel riveting forming, the inner wall adopts 1Cr18Ni9Ti heat-resistant transcription steel plate, and the inner lining adopts high-quality all-fiber structure. A layer of rubber asbestos board is attached to the furnace shell to provide sound insulation and protect the furnace shell from being damaged. erosion. The heating element of the aluminum alloy annealing furnace adopts the heating element to adopt 0Cr25AL5 alloy wire to be wound into a strip shape, sleeved on an insulating porcelain tube, and vividly on the furnace shell through stainless steel round steel. This kind of structure resistance band is hung around the furnace, which is unprofitable. With heat distribution and circulation. The installation of the Foehn wind cycle is composed of a fan installation and a wind deflector. The fan is installed on the top of the furnace body, and the fan is made of 1Cr18Ni9Ti heat-resistant steel into a centrifugal fan blade. The wind deflector is made of 1Cr18Ni9Ti heat-resistant steel, which is vividly placed on the inner wall of the furnace through a number of racks to wrap the resistance band on the outside. After the foehn wind cycle, the heat distributed by the resistance band continues to heat cycle, so that the heat in the furnace is evenly balanced. The ventilation installation is made according to the volume of the furnace to ensure that the number of cycles of the foehn fan is above 40 times per second.
