Steel coil supporting structure for silicon steel high-temperature heat treatment furnace and construction method

Abstract

The invention provides a steel coil supporting structure for a silicon steel high-temperature heat treatment furnace and a construction method. The supporting structure includes an even number of first support bodies, an equal number of second support bodies and an equal number of steel coil bricks. The first support bodies and the second support bodies are formed by laying a plurality of refractory bricks respectively, are arranged alternatively, and are arranged radially on the surface of a bogie. According to the supporting structure, gaps are left among the first and second support bodiesto facilitate air flow, thus achieving a good flow guiding effect, improving the flow field and the temperature field in a steel coil heat treatment process and further improving steel coil heat treatment quality. The supporting structure is stable, increases the yield of silicon steel and prolongs the service lifetime of the bogie.

Description

technical field [0001] The invention relates to the technical field of heat treatment equipment, in particular to a steel coil support structure and a construction method for a silicon steel high temperature heat treatment furnace. Background technique [0002] The high-temperature annular annealing furnace is the main process and equipment for silicon steel production. The furnace is composed of a preheating section, a heating section, a soaking section, and a cooling section. The maximum furnace temperature can reach 1300°C. The silicon steel coil to be heated is usually placed on the furnace bottom trolley in the form of a vertical coil to realize the heat treatment of the steel coil. [0003] At present, the steel coil support structure on the trolley is: a support plate, multi-layer refractory bricks are arranged on the trolley, the support plate is covered on the refractory bricks, and the steel coil is placed on the support plate. The close contact between the suppor...
