Abstract
The utility model relates to a convection disc used for steel coil annealing treatment. The convection plate comprises a base plate and guide plates, wherein the guide plates are uniformly arranged at the periphery of the obverse side and reverse side of the base plate; the base plate is provided with a central hole; and at least one expansion joint used for compensating the expansion and contraction deformation of the base plate is arranged on the base plate. As the convection disc used for the steel coil annealing treatment has the expansion joint arranged on the base plate, when the base plate is heated or cooled, the expansion and contraction deformation can be compensated through the expansion joint, therefore, the plastic deformation of the base plate caused by the expansion and contraction can be reduced, and the problem that the weld of the base plate is cracked due to the expansion and contraction is solved.
Description
Technical field
The utility model relates to the heat treatment technics field, especially a kind of be used for that coil annealing handles to flow table.
Background technology
Wide strip need carry out anneal in cold rolling after rolling process is finished, when using bell type annealing furnace to carry out anneal, generally be with the vertical stacking of multireel steel band in stove, placement finishes and covers the protective atmosphere that is driven in the inner cover by the table recirculation blower behind the inner cover and flows in internal recycling, prevents from also can remove with steel oxidation at high temperature the grease of the decomposition carbonization on surface; Place between the volume of two-phase adjacent band up and down and have radial passage flow table is heated evenly to guarantee the roll coil of strip.Flow table generally is made up of substrate that has centre hole and the even radial flow deflector that is arranged on the substrate pros and cons at interval, is gone up between the adjacent baffle with one side and form the air channel.Because anneal is (about 600-650 ℃) that carries out under higher temperature, under this temperature, to flow table (especially substrate) thus phenomenon that can expand with heat and contract with cold cause substrate deformation even cause the part weld seam to snap, bring potential danger to hoisting process to flow table.Substrate deformation also will influence the levelness that coil of strip is placed the back reference plane, thereby influence the circulation quality of internal protection gas.
Summary of the invention
The purpose of this utility model be to provide a kind of be used for that coil annealing handles to flow table, to solve the existing problem that the substrate of flow table is in use deformed, snaps because of expanding with heat and contract with cold.
In order to address the above problem, of the present utility model be used for that coil annealing handles to flow table by the following technical solutions: a kind of be used for that coil annealing handles to flow table, comprise that substrate reaches the flow deflector that circumferentially is distributed on the described substrate pros and cons, have centre hole on the described substrate, described substrate is provided with at least one expansion joint that is used to compensate the deformation of expanding with heat and contract with cold of substrate.
Described each expansion joint all has the cecum that the opening end that is positioned at described substrate outer edge reaches close substrate center hole.
Described substrate is provided with two above expansion joints, and each expansion joint is along circumferential uniform being arranged on the substrate of substrate.
All along the radially extension of described substrate, the sealing that is positioned at substrate surface at each expansion joint is covered by described each flow deflector at described expansion joint.
Since of the present utility model be used for that coil annealing handles flow table is provided with the expansion joint on its substrate, the expansion joint can compensate the deformation of expanding with heat and contract with cold of substrate when basal plate heated or cooling, thereby alleviate the plastic deformation that substrate produces owing to expanding with heat and contract with cold, solved the problem that substrate snaps owing to expanding with heat and contract with cold.
Further, described expansion joint is made as open type away from an end in substrate center hole, and the other end is a cecum, can guarantee the due intensity of substrate like this, can increase the compensate for clearance at expansion joint again, thereby reaches the compensation effect at expansion joint to greatest extent; Described expansion joint all is covered in the flow deflector, can reduce the shear-stress of substrate in the place, expansion joint like this by the load-bearing of flow deflector, has further guaranteed the intensity of substrate.
