Embodiment Construction

[0012] The silicon steel annular furnace cooling device of the present invention will be described below in conjunction with the accompanying drawings.

[0013] The present invention comprises a cooling water main pipeline 5, a cooling water section pipeline 8, a cooling water branch pipeline 9, an inner cover 4, a spraying device 11, a water collection tank 12, a drainage pipe 13, a water diversion tank 14, a water tank 15, a steam discharge pipe 16, The discharge valve 17 and accessories form a complete spray cooling system.

[0014] The cooling water main pipe 5 is used to supply water to the cooling zone of the annular furnace, which is fixed on the steel structure of the annular furnace roof 3, either inside or outside, and is about 400mm higher than the furnace roof 3, and is made of carbon steel pipes. The number of hearths 1 in the cooling zone, usually the number of hearths in the cooling zone of the silicon steel annular furnace is 6 to 8 sets, and a corresponding nu...

Abstract

An indirect water cooling device for an oriented silicon steel high-temperature annular furnace belongs to the technical field of silicon steel high-temperature annular furnaces in iron and steel plants. The indirect water cooling device comprises a cooling water main pipeline (5), a cooling water section pipeline (8), a cooling water branch pipeline (9), an inner cover (4), a spraying device (11), a water collecting tank (12), a water draining pipe (13), a water guiding tank (14), a water tank (15), a steam discharging pipe (16) and a drain valve (17). The indirect water cooling device has the advantages that a water cooling system is arranged in the hearth space of the oriented silicon steel high-temperature annular annealing furnace to spray and cool the inner cover of a silicon steel coil by adopting a water medium to realize indirect cooling to the silicon steel coil, meanwhile, cooling water is collected and discharged out of the furnace, and water vapor is discharged out of thehearth. Compared with traditional air cooling, an indirect cooling method has the advantages that the cooling speed can be greatly increased, the performance of the silicon steel coil is improved, theyield of the silicon steel coil is increased, and good application prospects are achieved.

Description

technical field [0001] The invention belongs to the technical field of silicon steel high-temperature annular furnaces in iron and steel plants, and in particular provides an indirect water cooling device for oriented silicon steel high-temperature annular furnaces, which can accelerate the cooling of silicon steel coils in the cooling zone of silicon steel annular furnaces, and can greatly improve the performance and performance of oriented silicon steel. Yield. Background technique [0002] Grain-oriented silicon steel is an indispensable and important soft magnetic functional material in the electric power and electronic industries, which has the characteristics of high magnetic induction and low iron loss. In today's world, with China's large-scale power construction, the domestic market for grain-oriented silicon steel is vast, and the demand for grain-oriented silicon steel with high performance, higher magnetic induction, and lower iron loss is becoming more and more ...
