Abstract
The invention discloses a device and method for high-temperature annealing of oriented silicon steel coils. The device comprises a hollow circular ring structure and a hollow cylinder structure. One end of the hollow cylinder structure is arranged on the end face of the hollow circular ring structure, the internal diameter position of the first end of the hollow cylinder structure corresponds to the internal diameter position of the hollow circular ring structure, and the internal diameter of the first end of the hollow cylinder structure is equal to that of the hollow circular ring structure. The external diameter of the hollow circular ring structure is larger than that of the hollow cylinder structure. The hollow interior of the hollow circular ring structure and the hollow interior of the hollow cylinder structure form a horn-shaped structure. The device is made of heat-resistant fireproof materials.
Description
technical field [0001] The present application relates to the technical field of oriented silicon steel manufacturing, in particular to a device and method for high-temperature annealing of oriented silicon steel coils. Background technique [0002] The high-temperature annealing process of oriented silicon steel is a key process to determine the performance of the finished product of oriented silicon steel. The temperature uniformity of the steel coil in the process is closely related to the quality of the finished product. It will cause a series of problems such as local magnetism, plate shape and surface. At present, the annealing process of industrial production of oriented silicon steel is generally to put the steel coil in the steel cover and protect it with atmosphere, and then put it into the furnace for annealing. The weight of the steel coil often reaches more than 15 tons, and its coil diameter exceeds 1.5m. It is extremely difficult to uniformly heat such a larg...
