Description

Technical Field

[0001] The utility model relates to the technical field of safety production auxiliary equipment for steel plants, in particular to a full-automatic water-cooled pneumatic baffle device in a high-temperature environment. Background Art

[0002] At present, there is no equipment installed on the rollers of steel mills to prevent low-temperature steel or misoperation from causing low-temperature billets to bite into the rolling mill. All are manually operated. When unqualified billets or low-temperature billets are found, the rollers are manually stopped and then removed.

[0003] The current technology has the following disadvantages: 1. In order to reduce dust on site, all the rollers of the heating furnace are sealed with insulation covers. However, since the rollers are long, it is easy for unbitten steel billets to remain in the rollers after the rolling line stops. After the production is turned around again, it is easy for low-temperature steel billets to be fed into the rolling mill, causing major accidents that damage the equipment.

[0004] 2. The rolling line suddenly breaks down and stops, and the red light comes on. At this time, if the billet has already run to the mill outlet, if the employees fail to find it in time or the manual operation is slow, it is easy to send the billet into the mill, causing cost losses, or even steel piling accidents.

[0005] 3. During direct rolling, the temperature of the steel billet is low and needs to be removed and returned to the furnace. Employees need to manually straighten the steel billet before removing it. If the response is not timely or the roller speed is too fast, the steel billet will be sent into the rolling mill by inertia, causing equipment damage accidents.

[0006] Therefore, there is an urgent need to design a fully automatic water-cooled pneumatic baffle device in a high-temperature environment to solve the problem of avoiding heating of unqualified low-temperature steel billets and preventing unqualified steel billets from biting into the rolling mill due to employee misoperation.

DETAILED DESCRIPTION

[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely further describe the technical solutions in the embodiments of the utility model. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] Embodiment 1:

[0024] like Figure 1 As shown, a fully automatic water-cooled pneumatic baffle device for high temperature environment includes a pneumatic structure 1, a baffle 2 and a frame 3. The pneumatic structure 1 is installed on a mounting plate 1.9 at the upper part of the device. The baffle 2 is connected to the pneumatic structure 1 through a cylinder rod 1.2 at the bottom. The baffle 2 moves up and down in a baffle limiting frame 2.1 in the frame 3 under the drive of the pneumatic structure 1. Two air pipes and two water pipes are respectively provided outside the pneumatic structure 1. The device is installed at the end mill entrance of the roller table.

[0025] A pneumatic structure 1 is installed on the upper part of the device, and the pneumatic structure 1 includes a cylinder 1.1, a cylinder rod 1.2, an air inlet 1.5, an air outlet 1.6, a water cooling cover 1.3, a water inlet 1.7, and a water outlet 1.8. A serpentine tube 1.4 is provided in the water cooling cover 1.3. A cylinder 1.1 is provided inside the pneumatic structure 1. The cylinder 1.1 and the cylinder rod 1.2 are used to provide power for the baffle 2. Two air pipes are provided outside the pneumatic structure 1, which are respectively connected to the air inlet 1.5 and the air outlet 1.6 to provide pressure for the cylinder 1.1. Two water pipes are connected outside the pneumatic structure 1, which are respectively connected to the water inlet 1.7 and the water outlet 1.8. The serpentine tube 1.4 is connected to the water inlet 1.7 and the water outlet 1.8 inside the water cooling cover 1.3, and is used to cool down the device when it is running for normal use.

[0026] The upper part of the baffle plate 2 is connected to the cylinder 1.1 through the cylinder rod 1.2. The baffle plate 2 is installed in the baffle plate limiting frame 2.1. The baffle plate 2 is used to fall down when the red light is on to block the unqualified steel billets.

[0027] The frame 3 is the main supporting and fixing part, which is composed of a vertical plate 3.1, a stabilizing plate 3.2 and a rib plate 3.3. The vertical plate 3.1, the stabilizing plate 3.2 and the rib plate 3.3 are used to stabilize the device. The baffle limiting frame 2.1 is used to limit the baffle 2 to avoid accidents caused by the displacement of the baffle 2.

[0028] Embodiment 2: Specific implementation steps using the structural form of embodiment 1.

[0029] At the end of the roller table, a high-temperature-proof water-cooled fully automatic pneumatic baffle 2 is designed in front of the rolling mill inlet, and is interlocked with the red, yellow and green light signals of the rolling line (red light stops steel tapping, green light continuously tapping, yellow light single tapping) and the pyrometer on the furnace roller table. As long as the rolling line turns red or the pyrometer detects that the temperature of the billet is lower than the set temperature, the pneumatic baffle 2 automatically falls and issues a voice alarm. Prevent the billet from biting in. When the rolling line turns green or yellow, the pneumatic baffle 2 automatically rises. If it does not rise, a voice alarm will be issued to remind the operator to pay attention. It also realizes remote operation, and employees can operate on the operating table. Because the temperature of the furnace billet is about 1000 degrees, it is easy to burn the seal of cylinder 1.1, which makes cylinder 1.1 unable to be used normally. Water cooling of cylinder 1.1 increases the service life of cylinder 1.1.
