Abstract
The utility model discloses a rest pad for steel band thermal treatment, including the rest pad, the rest pad is fan -shapedly, and is three the rest pad is constituteed the bearing plate and is used for supporting the steel band, and is three a ring is constituteed and reserve and have the expansion joint to the rest pad between two liang. There are enough extension spaces the inside and outside both sides of expansion joint and ring, guarantee can not produce the distortion after the rest pad is heated, warp, and the bearing plate that three rest pad is constituteed keeps the shape, and then guarantees that the steel band on the bearing plate is indeformable, improves product quality.
Description
Technical field
The utility model relates to a kind of for the heat treated rest pad of steel band.
Background technology
Cold-rolled steel strip has an important step to be annealing in producing, carrying out annealing process after cold rolling is plasticity in order to improve steel band and toughness, makes chemical composition homogenizing, removes unrelieved stress.In annealing steps, coil band is put into heat treatment furnace, under the high temperature more than 600 DEG C, through the anneal of 12 hours.Usually, stacking 3 coil bands in each heat treatment furnace, place the supporting plate of a patty under steel band.But due to every coil band weight very large (generally more than 25 tons), through heat supporting plate by thermal softening, can produce distortion, distortion, steel band is also followed and is produced distortion, has a strong impact on quality product simultaneously.
Utility model content
In order to overcome the deficiencies in the prior art, the utility model provides a kind of can keep shape for the heat treated rest pad of steel band after being heated, not yielding, improves strip product quality.
The utility model solves the technical scheme that its technical problem adopts:
A kind of for the heat treated rest pad of steel band, include rest pad, described rest pad is fan-shaped, and three described rest pads composition supporting plates are for supporting steel band, and three described rest pads form an annulus and are reserved with expansion joint between any two.
As the improvement of technique scheme, described rest pad material is spheroidal graphite cast iron.
As the further improvement of technique scheme, the thickness of described rest pad is at least 80mm.
Further, the width at described expansion joint at least 80mm.
The beneficial effects of the utility model are: by three fan-shaped rest pads are formed circular supporting plate, and rest pad reserved expansion joint between any two, can stretch to four sides after rest pad is heated, avoid occurring distortion, distortion, and then prevent the strip deformation of supporting on it, eliminating traditional patty supporting plate is heated yielding, causes strip deformation and affects the defect of quality product.The utility model is simple and practical, and implement simple, cost is low.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is described in further detail.
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the utility model using state schematic diagram.
Embodiment
With reference to Fig. 1 ~ Fig. 2, one is used for the heat treated rest pad of steel band, includes rest pad 1, and described rest pad 1 is in fan-shaped, three described rest pads 1 form supporting plate for supporting steel band, and three described rest pads 1 form an annulus and arrange and be reserved with expansion joint 2 between any two.Adopt said structure, can stretch to four sides after rest pad 1 is heated, there are enough extending spaces the inside and outside both sides of expansion joint 2 and annulus, ensure that rest pad 1 can not produce distortion, distortion, ensure that the supporting plate that three rest pads 1 form keeps shape, and then steel band on guarantee supporting plate is indeformable, improves the quality of products.
In the present embodiment, preferably, described rest pad 1 material is spheroidal graphite cast iron.Spheroidal graphite cast iron intensity is high, is heated not yielding, is conducive to keeping shape.
In the present embodiment, preferably, the thickness of described rest pad 1 is at least 80mm.80mm is a preferred gauge, under the prerequisite of proof strength, reduces weight as far as possible, is convenient to carrying.
In the present embodiment, preferably, the width at least 80mm at described expansion joint 2.The width 80mm at expansion joint 2 is preferred sizes, ensures that rest pad 1 can not produce interference by hot stretched, and increases the upper surface area of the supporting plate that three rest pads 1 form as far as possible, is beneficial to support steel band.
The above, just better embodiment of the present utility model, but the utility model is not limited to above-described embodiment, as long as it reaches technique effect of the present utility model with any same or similar means, all should fall within protection domain of the present utility model.
