Flexible ruler for controlling mansonry horizontal seam of coke oven refractory material

Abstract

The invention relates to a flexible ruler for controlling the mansonry horizontal seam of the coke oven refractory material. The flexible ruler is a strip straight scale (1) which is made from plastics, the two side edges in the length direction of the straight scale are separately provided with a plurality of datum cutter points (2) which are distributed evenly and are used for the wall guy of the regenrative chamber and a plurality of datum cutter points (3) used for wall guy of the combustion chamber, and upper notchs (4) which is used to fix the straight scale at the furnace end and lower notchs (5) which is used to fix the straight scale at the furnace end are separately arranged between the two cutter points on the upper and lower ends of the straight scale in the length direction. The flexible ruler of the invention overcomes the problem that when the wall bricks of the regenrative chamber and the combustion chamber are laid form bottom to top, the horizontal seam is not uniform and partial mortar joints are out of limits, combines the advantages that the masonry datum using the mark post has high level and the masonry datum without using the mark post is not easy to change, eliminates the defects that the masonry datum using the mark post is easy to touch and the masonry datum without using the mark post uses the furnace end as the datum so that the level is not high enough; and the flexible ruler is convenient to carry, has two purposes and can be used repeatedly.

Description

technical field [0001] The invention relates to a masonry quality control tool, in particular to a flexible scale for controlling horizontal joints of coke oven refractory masonry. Background technique [0002] In coke oven masonry construction without benchmarks, in the past when the coke oven regenerator and combustion chamber wall were masonry, the burner head parts at both ends of the wall were first built by highly skilled workers, and a maximum of 10 layers were built every day (reservoir) heat chamber) or 8th floor (combustion chamber), keep a good frame according to the regulations, the middle part of the wall is built by ordinary workers according to the joints of the furnace head bricks, and the surface elevation of the uppermost layer is checked by measuring. The allowable error: the top of the wall is ± 4mm (regenerator), ± 5mm (combustion chamber) control, the elevation difference of adjacent wall tops is 3mm (process control is 5mm), because the ash joint of th...

[0002] In coke oven masonry construction without benchmarks, in the past when the coke oven regenerator and combustion chamber wall were masonry, the burner head parts at both ends of the wall were first built by highly skilled workers, and a maximum of 10 layers were built every day (reservoir) heat chamber) or 8th floor (combustion chamber), keep a good frame according to the regulations, the middle part of the wall is built by ordinary workers according to the joints of the furnace head bricks, and the surface elevation of the uppermost layer is checked by measuring. The allowable error: the top of the wall is ± 4mm (regenerator), ± 5mm (combustion chamber) control, the elevation difference of adjacent wall tops is 3mm (process control is 5mm), because the ash joint of the furnace head is controlled by the level of personal operation, it is easy to cause the last 2-3 floors to start to find When adjusting the elevation, the elevation can only be adjusted through the few remaining mortar joints, resulting in too large or too small individual mortar joints, and the result meets the requirements of the elevation, and the thickness requirements of the mortar joints are +2, -1 (regenerator), ±1mm (combustion chamber) is hard to reach

If there is a problem with the furnace head benchmark, it will be more difficult to guarantee the quality of the middle wall masonry
