The silicon steel ring annealing furnace is a high temperature and high precision annealing equipment.It can perform high temperature treatment on silicon steel strips,significantly improving their physical properties and enhancing their magnetic and electromagnetic properties,making therm widely applicable in fields as power,transportation and communication.The high temperature annealing manufacturing technology of silicon steel strips id one of the key links in the entire production of silicon steel strips,and the steel structure of iron and steel's silicon steel ring annealing furnace is an important support for realizing this technology,It also ensures the service life of bottom roller graphite carbon sleeve.
The steel structure of the silicon steel ring annealing furnace is mainly composed of steel plates,straight pipes.curved pipes,insulation layers,fans,,air preheaters, especially with bottom roller graphite carbon sleeve.Its main structure is ring - shaped structure composed of straight and curved pipes,which are connected to each other through steel plates and fixed on a a ring-shaped foundation.The connection between the straight pipe and the curved pipe is a flexible coupling device, which can cause a certain displacement of the straight pipe relative ti the curved pipe.The insulating layer and insulation player are located inside and outside the furnace body,respectively,playing the role of insulation and thermal insulation.The bottom roller graphite carbon sleeve is arranged in a roller conveyor shape at the bottom of the annealing furnace,the bottom roller graphite carbon sleeve is replaced according to its the service life.the auxiliary components such as fans,air preheaters and flues are used to achieve temperature regulation and flue gas emission during the annealing process
