Abstract
The invention discloses a steel coil support device for an oriented silicon steel high-temperature heat treatment furnace with flow guide plates, which belongs to the technical field of oriented silicon steel high-temperature heat treatment. The device comprises a support plate, the flow guide plates and lifting lugs, wherein the flow guide plates are uniformly arranged on the lower surface of the support plate along the radial direction of a circle centre; and the three lifting lugs are arranged on the side part of the support plate at an equal distance. The device has the following advantages that a flow field and a temperature field during a heat treatment process for silicon steel coils can be improved, and then the heat treatment quality of the steel coils is improved; meanwhile, the lifting lugs are connected with the flow guide plates by means of socket welding, thus guaranteeing the lifting safety thereof after many times of heat treatment.
Description
Technical field
The invention belongs to oriented silicon steel high-temperature heat treatment technical field, particularly a kind of oriented silicon steel high temperature heat treatment furnace coil of strip bracing or strutting arrangement with flow deflector.
Background technology
At present domestic and in the world all kinds of oriented silicon steel high temperature heat treatment furnace all adopt bell furnace and ring furnace two kinds of forms, bell furnace is applicable to small serial production, and ring furnace is applicable to continuous seepage in enormous quantities.In these two kinds of processing modes, oriented silicon coil of strip is all on take vertical roll form to be placed on back up pad plane that refractory materials or metallic substance make.Oriented silicon coil of strip is placed in traditional back up pad plane, the bottom of volume and back up pad close contact, substantially gap is not had, such structure makes coil of strip self, particularly bottom coil of strip in thermal treatment heat temperature raising and the formation temperature gradient in process that cools, bottom is protruded to cause coil of strip to occur, is commonly called as heat treating faults such as " elephant pin ", has a strong impact on the high-temperature heat treatment quality of oriented silicon steel.In addition, traditional back up pad general thickness only has about 20mm, effectively cannot completely cut off bottom refractory material and cause oriented silicon coil of strip temperature controlled delayed because heat storage capacity is different, equally also can produce the major defects such as coil of strip deformation of bottom.
Summary of the invention
The object of the present invention is to provide a kind of oriented silicon steel high temperature heat treatment furnace coil of strip bracing or strutting arrangement with flow deflector.Solve oriented silicon steel coil of strip in high-temperature heat treatment process, by the impact of table structure and refractory materials, cause the problem that each spot temperature of coil of strip is uneven, template lumber recovery is lower.
The present invention includes: back up pad 1, flow deflector 2 and hanger 3.Wherein, flow deflector 2 is evenly arranged along center of circle directions of rays at the lower surface of back up pad 1, flow deflector 2 and back up pad 1 are welded to connect, can guarantee that furnace gas forms circulation in heat treatment process, make to be exposed to other bottom coil of strip that position in furnace gas equally obtains fully, uniform heating or cooling, reduce and avoid all kinds of defects that produce because of coil of strip non-uniform temperature, improving coil of strip thermal treatment quality; At the sidepiece spaced set three place hanger 3 of back up pad 1, hanger 3 inserts back up pad 1, and welds with back up pad 1, can prevent after multicycle thermal treatment hanger 3 weld strength and reduce and the potential safety hazard that causes.
Wherein, back up pad 1 is the circular configuration of hollow, and thickness is 40 ~ 200mm, and upper surface is smooth through processing treatment, can be used for coil of strip and places.
Flow deflector 2 is fan-shaped, and the distribution angle in back up pad 1 is 5 ~ 18 °; Flow deflector 2 is for whole piece or be divided into 2 ~ 4 sections; The thickness of flow deflector 2 is 20 ~ 100mm.
Hanger 3 is U-shaped, and the degree of depth inserted in back up pad 1 is 50 ~ 100mm, can guarantee Hoisting Security, and after multicycle thermal treatment, still can keep good function.
The invention has the advantages that: 1) there is good guide functions, the Flow and heat flux in silicon steel coil heat treatment process can be improved, and then improve the thermal treatment quality of coil of strip; 2) Stability Analysis of Structures, not yielding, can reuse, the heat treated production of complete accommodate silicon coil of strip and process system; 3) easy to operate, the hanger of particular design, can make lifting work become simple, have very high safety performance simultaneously.
