Detailed Description
For the purpose of making the objects, technical solutions and advantages of the embodiments of the present utility model more apparent, the technical solutions of the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model, and it is apparent that the described embodiments are some embodiments of the present utility model, but not all embodiments of the present utility model. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.
The utility model provides an auxiliary device for preventing hot-rolling flat coil defects for the existing difficult problem. Can play a role when the coil of strip takes place flat roll defect, through the coil of strip dead weight, make coil of strip both sides and auxiliary device produce mutual holding power, play the centre gripping effect to the coil of strip both sides, and then change the coil of strip shape, play the effect of recovering the coil of strip shape fast.
As shown in figures 1-2, an auxiliary device for preventing hot-rolling defects mainly comprises a base 1, a support cushion block 2 and a scratch-proof plate surface 3. The method specifically comprises the following steps: the base 1 and two groups of supporting devices installed on the base 1 are identical in structure and symmetrically arranged. The base 1 is parallel to the horizontal plane. Each group of supporting device comprises supporting cushion blocks 2 connected to the base 1, each supporting cushion block 2 is provided with an inclined surface, and the inclined surface is provided with a scratch-proof plate surface 3. The two scratch-proof plate surfaces 3 on the two groups of supporting devices are opposite to each other at intervals, and have the same inclination angle relative to the base 1, and the inclination angle theta is 45 degrees; the coiled steel coil is arranged between the two scratch-proof plate surfaces 3. The two support cushion blocks have the same structure and the same size.
In this embodiment, each supporting pad 2 includes two risers that the interval set up, and the cross-sectional shape of every riser is the polygon, and the incline limit that has on two risers is located the coplanar to form above-mentioned inclined plane, every scratch proof face 3 is connected with two incline limit that correspond. The bottoms of the two vertical plates are welded with the base 1, and the inclined edges of the two vertical plates are welded with the scratch-proof plate surface 3.
In this embodiment, the dimensions of the base 1, the cushion block 2, and the scratch-proof plate surface 3 are as follows:
base 1 dimensions (thickness d1×width w1×length L1): 32X 930X 2300mm. L1 is the maximum outer diameter of the rolled steel coil.
Scratch-resistant panel 3 dimensions (thickness d2×width w2×length L2): 32X 930X 1130mm.
Riser of the supporting cushion block 2: the side length dimensions (L2, L3, L4, L5) were 1130mm, 210mm, 650mm, 930mm, respectively, and the thickness D3 was a trapezoid of 32 mm. The spacing between two risers within the same set is 666mm. L1>2L5.

The working principle of the auxiliary device for preventing the defects of the hot-rolled flat coil is as follows: obvious phase change reaction occurs in the storage process of coiled steel coils, and volume expansion is caused. Because the temperature distribution of the inner part and the outer part of the steel coil is inconsistent, the phase change process and the expansion degree in the steel coil are different, and the difference causes interlayer dislocation of the steel coil to cause unreeling, so that the steel coil has flat coil defects under the action of dead weight. When the rolled steel coil is flat rolled, the flat coiled steel is hoisted to the upper surface of the auxiliary device through the crane clamp, and the flat coil tendency is restrained through the self weight of the steel coil and the mutual supporting force generated between the auxiliary device, so that the risk of flat coil generation of the steel coil is counteracted. Through the use of the auxiliary device, the coil shape quality of the steel coil can be effectively improved, and the generation of flat coil defects is greatly reduced, so that the production cost and the productivity of flat wires are reduced, and the yield of products is improved.
