Abstract
The utility model discloses a steel roll support device with guide plates for a high-temperature heat treatment furnace for oriented silicon steel, and belongs to the technical field of high-temperature heat treatment of oriented silicon steel. The device comprises a support plate, guide plates and lifting lugs, wherein the guide plates are uniformly distributed on the lower surface of the support plate along the central radial direction; three lifting lugs are arranged at the side part of the support plate at equal interval. The steel roll support device has the advantages that the device can improve flow fields and temperature fields in heat treatment of silicon steel rolls, and then improve the heat treatment quality of steel rolls, and the lifting lugs are connected with the guide plates in an insert welding mode, so that a situation that the lifting lugs subjected to multiple heat treatment are hoisted safely is ensured.
Description
Technical field
The utility model belongs to oriented silicon steel high-temperature heat treatment technical field, particularly a kind of oriented silicon steel high-temperature heat treatment stove 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 stoves all adopt bell furnace and two kinds of forms of ring furnace, bell furnace is applicable to small serial production, ring furnace is applicable to production continuously in enormous quantities.In these two kinds of processing modes, oriented silicon coil of strip is all to take vertical roll form to be placed on the back up pad plane that refractory materials or metallic substance make.Oriented silicon coil of strip is placed in traditional back up pad plane, bottom and the back up pad close contact of volume, substantially there is no gap, such structure makes coil of strip self, particularly coil of strip bottom formation temperature gradient in thermal treatment heat temperature raising and the process that cools, cause coil of strip to occur bottom protrusion, be commonly called as heat treating faults such as " elephant pin ", have a strong impact on the high-temperature heat treatment quality of oriented silicon steel.In addition, traditional back up pad general thickness only has 20mm left and right, cannot effectively completely cut off bottom refractory materials and cause the temperature controlled hysteresis of oriented silicon coil of strip 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 purpose of this utility model is to provide a kind of oriented silicon steel high-temperature heat treatment stove coil of strip bracing or strutting arrangement with flow deflector.Solve oriented silicon steel coil of strip in high-temperature heat treatment process, be subject to the impact of table structure and refractory materials, caused the each position of coil of strip temperature inequality, problem that template lumber recovery is lower.
The utility model comprises: back up pad 1, flow deflector 2 and hanger 3.Wherein, lower surface in back up pad 1 is evenly arranged flow deflector 2 along center of circle directions of rays, flow deflector 2 is welded to connect with back up pad 1, can guarantee that furnace gas forms circulation in heat treatment process, make coil of strip bottom and other be exposed to that position in furnace gas is the same to obtain fully, heat uniformly 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 sidepiece spaced set three place's hangers 3 of back up pad 1, hanger 3 inserts back up pad 1, and welds with back up pad 1, can prevent that after multicycle thermal treatment hanger 3 weld strengths reduce and the potential safety hazard that causes.
Wherein, the circular configuration that back up pad 1 is hollow, thickness is 40～200mm, 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 of inserting in back up pad 1 is 50～100mm, can guarantee Hoisting Security, and can after multicycle thermal treatment, still keep good function.
The utility model has the advantage of: 1) there is good guide functions, can improve flow field and temperature field in silicon steel coil heat treatment process, and then improve the thermal treatment quality of coil of strip; 2) Stability Analysis of Structures, not yielding, can reuse, completely the heat treated production of accommodate silicon coil of strip and process system; 3) easy to operate, the hanger of particular design, can make slinger become simple, has very high safety performance simultaneously.
