Description

Clamp for accurately controlling coke oven chute masonry size

Technical Field

The utility model belongs to the technical field of smelting engineering construction, especially, relate to a dimension fixture is built by laying bricks or stones for accurate control coke oven chute.

Background

The coke oven chute area is a very important part of the coke oven, and the operation core of the coke oven is the chute, which is used for feeding air into a combustion chamber of the coke oven through the chute and discharging combustion waste gas through an adjacent chute. Therefore, in the process, the requirements on the size of the chute are very strict, and the size change of the chute can affect the quantity change of air or exhaust gas fed into a combustion chamber of the coke oven in unit time, possibly causing the problem that the heating temperature of the combustion chamber can not reach the set value, and further affecting the production of the coke oven.

The chute parts of modern large-scale coke ovens are built by 9 layers of silica bricks, the thickness of each layer of silica bricks is 120mm, 68 or 72 chutes are arranged in each carbonization chamber, the number of the chutes of one coke oven reaches thousands, the 3-9 layers of the bricks of the chutes are rectangular, the size of each chute is 110mm (width) multiplied by 240 mm-420 mm (length), the sizes of the formed chute openings of all layers are different, the sizes of the chute openings need to be accurately controlled when each layer of bricks are built, particularly the width of the chute is controlled, the standard requirement error is-1-2 mm, and the times of the chute openings need to be accurately controlled by one modern large-scale coke oven reaches more than 3 thousands.

In the construction of the existing furnace building engineering, the chute opening is generally controlled by clamping plates made of T-shaped wood plates, and the concrete construction method comprises the steps of firstly building silica bricks on one side of the long edge of the chute opening, then building silica bricks on the other side, simultaneously placing the clamping plates at one end of the chute opening, taking out the clamping plates after the size of the chute opening is adjusted, placing the clamping plates at the other end of the chute opening, and then adjusting the width of the chute opening for the second time.

The problems with this approach are: (1) the clamping plate is generally made of wood plates or multi-layer plywood, and after the clamping plate is contacted with water in masonry slurry for a long time, the clamping plate is easy to deform and expand, so that the size deviation of the clamping plate is caused, and the accurate control of the size is not facilitated; (2) the clamping plate is a single plate, the control of the verticality between the clamping plate and the side surface of the silica brick mostly depends on the visual judgment of an operator, and errors are easy to generate; (3) when the clamping plate moves from one end of the chute port to the other end of the chute port, the brick position needs to be moved and adjusted, and at the moment, one end of the chute port loses positioning control, so that the silica brick generates position deviation, and the size of the chute port and the parallelism of two side surfaces are difficult to meet the requirements.

Based on above problem, the utility model provides a be used for accurate control coke oven chute to build by laying bricks or stones size fixture can build by laying bricks or stones the size and carry out accurate control to coke oven chute, reduces the error, prevents that the silica brick from producing offset, practices thrift the manual work, improves the efficiency of construction.
