Description

Technical Field

[0001] The utility model belongs to the technical field of stainless steel production equipment, in particular to a production device for overcoming the soft and hard edges of hot-rolled ferrite stainless steel. Background Art

[0002] After hot-rolled stainless steel is coiled, the steel coil needs to be placed in a designated location for natural cooling before entering downstream enterprises for processing. However, the existing cooling sites generally have the following problems during use: 1) Since the steel coil is obtained by coiling steel strips, during the natural cooling process, the surface temperature of the outermost layer and edge of the steel coil that is directly in contact with the air drops too quickly, while the internal temperature of the steel coil drops too slowly. The uneven cooling temperature causes changes in the stress inside the steel strip, resulting in differences in the overall strength and toughness of the steel strip, affecting the final processing; 2) Most of the existing insulation devices directly cover the steel coil with an insulation cover. Although it can improve the impact of temperature changes on the steel coil to a certain extent, it cannot adjust the cooling speed. Although the cooling is stable, the cooling speed of the steel coil is too slow, affecting the circulation efficiency of the steel coil.

[0003] After searching, the prior art CN214361589U discloses a heat preservation device for reducing the internal stress of steel coils, including a motor provided inside the front and rear side walls of a box body, a threaded rod fixedly connected to the output end of the motor, a limit block fixedly connected to the top of the threaded rod, a buffer pad fixedly connected to the bottom of the limit block, an internal threaded pipe threadedly sleeved on the surface of the threaded rod, connecting rods fixedly connected to the left and right surfaces of the internal threaded pipe, a support rod fixedly connected to the end of the connecting rod, and a top plate frame fixedly connected to the top of the support rod; the above scheme drives the internal threaded pipe to move by driving the motor to drive the threaded pipe to rotate, and then drives the connecting rod to move. The connecting rod, supporting rod and top plate frame move up and down so that the top plate moves up and down, and the side panels of the box are connected to the box by hinges, so that the top plate and side panels can be adjusted to open and close, thereby facilitating the adjustment of the temperature drop rate of the steel coil placed in the box, and achieving the purpose of controlling the cooling rate of the offline steel coil; however, the above technical solution cannot understand how to adjust the limit fixation of the steel coil in the box during use. Although the top plate can be moved up and down by driving several connections through a motor, the way in which the side panels of the box are hinged to the box requires workers to perform manual adjustments, which greatly increases the work intensity and work risks.

[0004] For another example, the prior art CN215555099U discloses a heat preservation cover and a steel coil conveying trolley, comprising a lifting section heat preservation cabin and a top opening and closing heat preservation cabin, the lifting section heat preservation cabin comprising a bottom section shell, a movable section shell and a lifting drive device, the movable section shell is sleeved with the bottom section shell, and the lifting drive device drives the lifting and lowering of the movable section shell; the top opening and closing heat preservation cabin is connected to the upper opening of the lifting section heat preservation cabin, comprising an opening and closing cover shell, the opening and closing cover shell is a telescopic mechanism, the opening and closing cover shell is in an extended state, the top surface of the opening and closing cover shell is a semicircular arc surface, and the upper portion of the lifting section heat preservation cabin The opening is closed; the opening and closing cover is in a retracted state, and the upper opening of the insulation cabin of the lifting section is opened; the above scheme opens the upper opening of the insulation cabin of the lifting section to place or take out the steel coil, so as to achieve insulation and slow cooling during transportation or storage; however, the above technical scheme cannot adjust the insulation cover during use, thereby unable to control the cooling speed of the steel coil. Since the performance of steel coils of various specifications is different, the requirements for cooling speed are also different. Therefore, the above technical scheme cannot have a good adaptability to the insulation and cooling of steel coils of various specifications, resulting in slow cooling efficiency.
