Application of PLC in vacuum heat treatment furnace control system have? Vacuum heat treatment is applied to the manufacturing industry, in order to have good performance of industrial products necessary intermediate step, it is a branch of the heat treatment, the main purpose is to prevent oxidation and decarbonization of the workpiece during machining. Due to the application of programmable controllers microelectronics and computer technology, a variety of control functions are implemented through software, just change the program, it can adapt to changes in the production process, and therefore adaptable. It is not only to complete the logic operation, timing, counting and other functions, and can perform arithmetic operations. Thus both switching volume control, but also for analog control, trolley furnace, but also with a computer linked to the Internet, new energy-efficient furnace materials, achieve hierarchical control. Moreover, PLC, small size, light weight, compact, short development cycle, installation and less maintenance. Therefore, in the course of industrial furnace with microelectronics technology to transform traditional industries, the traditional relay control system, most of them were replaced by PLC. Structure Introduction This series trolley furnace by the furnace and electrical control of two parts. Furnace section includes furnace shell, lining, heating elements, door and car. Furnace shell from welded steel plate and steel form, laboratory furnace, the use of energy-efficient ultra-lightweight lining bricks, ceramic fiber insulation materials and high quality composite lining. Heating element with a high resistance wire wound into a spiral and placed on a trolley to put the brick lining; trolley can move back and forth, electric stove, easy loading and unloading, and the furnace shell between its adoption of new self-sealing, good sealing performance change shape ; lift the door out of the trolley deceleration mechanism are used in electric drive, heat-resistant steel casting furnace floor, and an optional trolley tilt discharge mechanism. Laboratory furnace, furnace, laboratory furnace by Longkou Longkou Furnace experiment. Longkou Experimental Furnace (www.lk-dianlu.com) in the field of electric equipment devoted boundless enthusiasm and passion, Longkou laboratory furnace has been customer-centric, for customers to create the concept of value, quality, service to win market , and sincerely hope to cooperate with the community to create success, to create brilliant.
