Technical Field

[0001] The invention belongs to the technical field of steel production and relates to a method for fixing a fire baffle plate for opening casting in a continuous casting machine. Background Art

[0002] The fire baffle used when pouring in the tundish of the continuous casting machine is fixed to the square wooden strip with a hammer and nails. This method has the following two problems: 1. Safety accidents are prone to occur when hammering nails (such as hammer hitting hands); 2. The square wooden strips will be burned after use and cannot be reused, which increases the labor intensity of workers. Summary of the invention

[0003] In view of this, the object of the present invention is to solve the above-mentioned problem and provide a method for fixing a fire baffle plate during pouring in a continuous casting machine.

[0004] In order to achieve the above object, the present invention provides the following technical solutions:

[0005] A method for fixing a fire damper for pouring in a tundish of a continuous casting machine comprises the following steps: three screws are fixedly installed on a fixed steel plate, and the three screws are arranged in an isosceles triangle; a T-shaped pressing plate is arranged between the three screws, and the fire damper is placed between the T-shaped pressing plate and the fixed steel plate; three ends of the T-shaped pressing plate are slidably sleeved on the three screws in a one-to-one correspondence, and the T-shaped pressing plate is pressed and fixed to the fire damper by tightening nuts; a handle is welded on one side of the fixed steel plate, and an operator uses the handle to hold the fire damper.

[0006] Furthermore, a strip hole is opened on the fixing steel plate, and the screws located at the vertices of the isosceles triangle are arranged in the strip hole and slide along the strip hole to adapt to deformation.

[0007] Further, when the fire baffle needs to be replaced, the nut on the screw is loosened to replace it.

[0008] Furthermore, the fixed steel plate is rectangular, and the handle is arranged along the length direction of the fixed steel plate.

[0009] Furthermore, the T-shaped pressure plate is welded by steel bars and nuts, and the inner diameter of the welded nuts is larger than the outer diameters of the three screws to meet the sliding requirements.

[0010] The beneficial effects of the present invention are:

[0011] The present invention optimizes the method of fixing the fire baffle, adopts three screws to connect the steel bars, and fixes the fire baffle board by tightening the movable nuts on the screws, thereby avoiding the risk of safety accidents occurring when manufacturing the fire baffle for pouring in the middle package, and the manufactured tools can be reused, thereby reducing the labor intensity of workers.

[0012] Other advantages, objectives and features of the present invention will be described in the following description to some extent, and to some extent, will be obvious to those skilled in the art based on the following examination and study, or can be taught from the practice of the present invention. The objectives and other advantages of the present invention can be realized and obtained through the following description. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] See also Figure 1 The invention discloses a method for fixing a fire damper for opening pouring in a continuous casting machine. Three screws 3 are fixedly installed on a fixed steel plate 2, and the three screws 3 are arranged in an isosceles triangle. A T-shaped pressing plate 4 is arranged between the three screws 3, and the fire damper 1 is placed between the T-shaped pressing plate 4 and the fixed steel plate 2. The three ends of the T-shaped pressing plate 4 are slidably mounted on the three screws 3 in a one-to-one correspondence, and the T-shaped pressing plate 4 is pressed and fixed to the fire damper 1 by tightening the nuts. A handle 5 is welded on one side of the fixed steel plate 2, and the operator holds the fire damper 1 by the handle 5.

[0020] The fixed steel plate 2 is rectangular, and the handle 5 is arranged along the length direction of the fixed steel plate 2. The fixed steel plate 2 is provided with a strip hole 6, and the screw 3 located at the vertex of the isosceles triangle is arranged in the strip hole 6 and slides along the strip hole 6 to adapt to deformation. When the T-shaped pressure plate 4 is slightly deformed by high temperature, the position of the screw 3 can be slightly moved.

[0021] When the fire baffle 1 needs to be replaced, loosen the nut on the screw 3 to replace it.

[0022] The T-shaped pressure plate 4 is welded by steel bars and nuts, and the inner diameter of the welded nuts is larger than the outer diameter of the three screws 3 to ensure sliding.
