Description

Technical Field

[0001] The present invention belongs to the technical field of smelting engineering construction, and in particular relates to a fixture for accurately controlling the masonry dimensions of a coke oven chute and a method of using the fixture. Background Art

[0002] The coke oven chute area is a crucial component of the coke oven. The chute is the core of its operation, supplying air to the coke oven combustion chamber and discharging combustion exhaust gases through adjacent chutes. Therefore, in engineering, the requirements for chute dimensions are very strict. Variations in chute dimensions can affect the amount of air supplied to the coke oven combustion chamber or the amount of exhaust gases discharged per unit time, potentially preventing the combustion chamber from reaching the set temperature, thus impacting coke oven production.

[0003] The inclined path of a modern large coke oven is made of 9 layers of silica bricks, with each layer of silica bricks being 120 mm thick. There are 68 or 72 inclined paths in each carbonization chamber. A coke oven has thousands of inclined paths. The 3rd to 9th layers of bricks are rectangular, with dimensions of 110 mm (width) × 240 mm to 420 mm (length). The dimensions of the inclined path openings formed by each layer are different. The dimensions of the inclined path openings need to be precisely controlled when laying each layer of bricks, especially the width of the inclined path. The standard error is -1 to 2 mm. A modern large coke oven needs to precisely control the number of inclined path openings reaching more than 30,000.

[0004] In the current furnace construction project, the inclined channel is generally controlled by a pallet made of T-shaped wooden boards. The specific construction method is to first lay the silica bricks on one side of the long side of the inclined channel, and then lay the silica bricks on the other side. At the same time, a pallet is placed at one end of the inclined channel. After adjusting the size of the inclined channel opening, the pallet is taken out and placed at the other end of the inclined channel, and then the width of the inclined channel opening is adjusted a second time.

[0005] The problems with this method are: (1) The pallets are generally made of wood or multi-layer plywood. After long-term contact with water in the masonry mud, the pallets are easily deformed and expanded, resulting in dimensional deviation of the pallets themselves, which is not conducive to precise size control; (2) The pallets are single boards, and the control of their perpendicularity to the side of the silica bricks mostly relies on the operator's visual judgment, which is prone to errors; (3) When the pallet moves from one end of the ramp to the other end, the brick position needs to be moved and adjusted. At this time, the positioning control of one end of the ramp is lost, which will cause the silica bricks to shift in position, making it difficult to meet the requirements for the size of the ramp and the parallelism of the two sides.

[0006] Based on the above problems, the present invention provides a fixture for accurately controlling the masonry dimensions of the coke oven ramp and a method of using the fixture, which can accurately control the masonry dimensions of the coke oven ramp, reduce errors, prevent positional displacement of silicon bricks, save labor, and improve construction efficiency. Summary of the Invention

[0007] The problem to be solved by the present invention is to provide a fixture for accurately controlling the size of the coke oven ramp and a method for using the same, which effectively solves the problem proposed in the background technology that the size cannot be accurately controlled due to the size deviation of the clamping plate itself, the error is large, and the two ends of the ramp mouth cannot be positioned simultaneously, resulting in positional offset of the silicon bricks. A fixture for accurately controlling the size of the coke oven ramp and a method for using the same are provided, which can accurately control the size of the coke oven ramp, reduce errors, prevent positional offset of silicon bricks, save labor, and improve construction efficiency.

[0008] To solve the above technical problems, the present invention adopts the following technical solution: a fixture for accurately controlling the masonry dimensions of a coke oven chute, comprising:

[0009] a first card plate and a second card plate, wherein the first card plate and the second card plate are parallel to each other;

[0010] a horizontal frame plate, the horizontal frame plate being disposed between the first card plate and the second card plate, the horizontal frame plate being perpendicular to the first card plate and the second card plate, and being used to connect the first card plate and the second card plate together;

[0011] A vertical frame plate is connected to the horizontal frame plate and is used to position the coke oven chute in a vertical direction.

[0012] Furthermore, the length of the first card plate is greater than the length of the second card plate.

[0013] Furthermore, the side endpoints of the first card plate and the second card plate are on the same horizontal plane;

[0014] The upper surfaces of the first clamping plate, the second clamping plate and the horizontal shelf are on the same horizontal plane.

[0015] Furthermore, the vertical frame plate and the horizontal frame plate are fixed via threaded connection.

[0016] A method for using the above-mentioned fixture for accurately controlling the size of coke oven chute masonry comprises the following steps:

[0017] Set the number of layers of silica bricks to be laid to n. When laying n layers of silica bricks:

[0018] Laying silica bricks on one side of the coke oven chute;

[0019] When laying the silica bricks on the other side of the coke oven chute, place the clamp and use the side surfaces of the first clamp and the second clamp to position the vertical surface of the silica bricks at the coke oven chute. The number of silica brick layers clamped by the first clamp at the same time is n-1.

[0020] After adjusting the position of the silicon bricks, remove the fixture;

[0021] Repeat the above steps.

[0022] The present invention discloses a fixture for accurately controlling the masonry dimensions of a coke oven ramp and a method for using the fixture, which can accurately control the masonry dimensions of the coke oven ramp, reduce errors, prevent silicon bricks from shifting in position, save labor, and improve construction efficiency.
