Trolley frame is made of welded steel forming, the steel guarantees under full load without deformation. Inside with brick masonry, easy collision site and the site of the building with a heavy load of brick, reinforced lining structural strength, walking trolley structure using self-propelled, driven by a gear drive sprocket wheel to go walking on the tracks. Trolley labyrinth seal with automatic double seal structure and soft touch, trolley into the furnace by the action of the cam ramps and rollers, sealed automatically rises. Trolley out of the sealing groove automatically fall, sealed tank filled by sand seal after having to constantly add. Trolley out, electronically controlled door movements are equipped with an electromagnetic brake furnace temperature controller, prevents inertial impaction experimental electric furnace, and the chain of control, open the door a little after that, automatically cut off the heating elements, while restoring Taiwan Car travel agency power. After the door closed in place, automatically cut off the power supply trolley running gear, while restoring the power of the heating element. Vacuum heat treatment technology for the future development prospects are there? Given the vacuum heat treatment is an efficient, high-quality, energy-saving, clean and pollution-free heat treatment of advanced technology, industrialized countries, 20% -25% of vacuum heat treatment production accounts for the total heat production, there are broad prospects for development, major development in trend: since the 1980s, widely used abroad instead of high pressure gas quenching oil quenching, in order to remove the cleaning process, improve surface quality. Early last century, 90 generations box furnace, in foreign countries has developed high-pressure gas quenching furnace, as mentioned above, but also has developed working pressure up to l00x10m3, operating temperature up to 2200 ℃ high temperature and pressure vacuum furnace temperature and high pressure to the development trend will continued. Widespread use of computer technology and network technology microelectronics, research and development of intelligent control systems and network management system, flexible and continuous operation of vacuum heat treatment technology and equipment. Furnace temperature controller, Longkou laboratory furnace (certified), provided by Longkou experimental furnace Furnace. Longkou experiment Furnace (www.lk-dianlu.com) is a leader in Yantai, Shandong Province, electric equipment, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customer needs. Longkou laboratory furnace leadership with the staff warmly welcome all inquiries negotiations to create experimental furnace Longkou a better future.
