The utility model relates to steel production equipment, in particular to a member structure suitable for preventing flat rolling of hot-rolled strip steel.
Background
In recent years, in the steel industry, the excess capacity and the homogenization competition are serious, so that the market is seriously supplied more than the demand, the global economy is reduced, the requirements of the steel industry are not vibrating, the price is continuously lowered, the upstream iron ore industry monopoly is monopolized, the prices of labor force, land, fuel power and the like are continuously raised, the cost pressure of production elements is increased, the ecological environment constraint is intensified, and the profit space of enterprises is further compressed. Therefore, the popularization of the cost-reducing and environment-friendly steel production process becomes a very necessary survival way.
The high strength and thinning are more and more emphasized by downstream customers, and meanwhile, the downstream customers have more and more requirements on the coil weight in order to improve the yield. However, in the process of producing high-strength steel and high-carbon steel, due to the thin specification, if the coil weight is further increased in the process of producing the high-carbon and high-strength steel, the hot-rolled strip steel still has more than 1 hour after being coiled to enter a finished product warehouse, and the hot-rolled strip steel can be coiled flatly, and cannot be coiled after being coiled flatly, and then is subjected to acid pickling and galvanizing and then is directly sent to a client, so that the use of the client is influenced, and the judgment can be made only.
Therefore, a process and a structural design which can improve the shape of the thin-gauge strip steel coil of 2.0mm or less and prevent flat coil are urgently needed.
SUMMERY OF THE UTILITY MODEL
The technical task of the utility model is to provide a member structure for preventing the flat rolling of hot-rolled strip steel, which can prevent the flat rolling of the strip steel when producing high-carbon steel and high-strength steel, meet the quality control requirement of the shape of the strip steel coil and meet the requirement of customers on the quality of the strip steel.
The technical scheme for solving the technical problem is as follows: a component structure for preventing flat rolling of hot-rolled strip steel is characterized in that: comprises a saddle, a butt clamp assembly, a coil conveying vehicle, a grating detection unit and a control unit; a gap is arranged in the middle of the saddle, and the coil support of the coil conveying vehicle is positioned in the gap; the upper end in the gap is provided with a radian matched with the steel coil; the two butt clamp assemblies are oppositely arranged, each side of each butt clamp assembly comprises a sector block and an oil cylinder, and the oil cylinder is used for pushing the sector block; the surface of the fan-shaped block facing the steel coil is provided with a radian matched with the steel coil; the oil cylinder, the coil conveying vehicle and the grating detection unit are respectively in signal connection with the control unit.
Furthermore, the saddle and the sector are connected through a slide block and a slide rail.
Furthermore, the butt clamp assembly is provided with two sets, the radians of one surface, facing the steel coil, of the two sets of the fan-shaped blocks are different, and the radians of the upper end in the gap of the saddle are consistent with those of the fan-shaped blocks at corresponding positions.
Compared with the prior art, the utility model has the following outstanding beneficial effects:
1. the utility model improves the coil shape, prevents the hot rolling of high-carbon and high-strength strip steel flat coil, realizes the production technical requirement of thin gauge strip steel and is also the requirement of client profit maximization;

Detailed Description
The utility model is further described with reference to the drawings and the detailed description.
The high-carbon steel has stronger heat storage capacity, the temperature of the coiled strip steel is high, the strip steel is softer under the condition that the surface is still red and the strip steel is flattened under the condition of self weight; the high-strength steel has higher strength of the strip steel, so that the layers are relatively looser during coiling, and the strip steel is easy to unwind after being uncoiled from a coiling drum. The thinner the high-carbon steel and high-strength steel are, the more severe the flat rolling condition is. Meanwhile, more and more customers hope to purchase large rolls of 20-25 tons, and the larger the roll weight, the more serious the flat roll is. The flat coil problem can not be recovered after warehousing because the time from coil unloading to warehousing is long.
Therefore, after the coil is unloaded from the winding drum, the steel coil 5 is clamped by adopting the structure of the utility model, so that the steel coil cannot be flattened due to self weight, the temperature is gradually reduced after waiting for 0.5-2min, the self strength of the strip steel is gradually increased, the probability of flat winding is greatly reduced in the subsequent coil transporting and warehousing processes, and the appearance of the strip steel coil is ensured.
The utility model is installed between the tail coiling machine and the bundling machine. Comprises a saddle 1, a butt clamp assembly, a coil conveying vehicle, a grating detection unit and a control unit.
A gap is arranged in the middle of the saddle 1, and the coil support 2 of the coil conveying vehicle is positioned in the gap. The upper end in the gap is provided with a radian matched with the steel coil 5.
The two oppositely-clamped assemblies are oppositely arranged, each side of each oppositely-clamped assembly comprises a sector 3 and an oil cylinder 4, and the oil cylinder 4 is used for pushing the sector 3. And one surface of the fan-shaped block 3 facing the steel coil 5 is provided with a radian matched with the steel coil 5.
In this embodiment, the width is 1250mm, and the coil weight is 20-25 tons of strip steel, and the coil diameter is theoretically about 1770-1950mm, so the stroke of the sector 3 is set to be 0-200 mm. The sector 3 is made of steel structure and is convenient to manufacture.
The saddle 1 and the segment 3 are connected through a sliding block and a sliding rail in the optimized scheme.
The oil cylinder 4, the coil conveying vehicle and the grating detection unit are respectively in signal connection with the control unit. The grating detection unit acquires the transverse and longitudinal coordinate positions of the steel coil 5 and transmits the transverse and longitudinal coordinate positions to the control unit, and then offline coil positioning and coil diameter detection are achieved. When the coil is positioned in the sector 3 area, the control unit controls the coil conveying vehicle to stop and reduce the coil support 2, and the steel coil 5 falls on the saddle 1 to realize the supporting force of the foundation. And then, the control unit starts the oil cylinder 4 to push the sector 3 for 0.5-2min, and after the temperature is gradually reduced and the strength of the strip steel is gradually increased. The control unit starts the oil cylinder 4 to recover and the coil support 2 of the coil conveying vehicle to ascend, and then the coil conveying vehicle advances to enter the next bundling process.
In the optimization scheme, the butt clamp assembly has two sets, the radian of one side of two sets of sector blocks 3 towards the steel coil 5 is different, and the radian of the upper end in the gap of the saddle 1 is consistent with the sector blocks 3 at corresponding positions. The design aim at is that the grating detection unit obtains the outer diameter of the steel coil 5, and the control unit selects the matched butt-clamping assembly according to the outer diameter.
The measurement, transmission and control of data involved in the present invention are well known in the art, and the connection and control will vary depending on the model and will not be described in detail herein.
It should be noted that while the utility model has been described in detail with respect to specific embodiments thereof, it will be apparent to those skilled in the art that various obvious changes can be made therein without departing from the spirit and scope of the utility model.
