Problems solved by technology
Due to the errors in the laying out of the adjacent Sanchakou, the setting and production of the tire rotation, rework of the composite bricks at the Sanchakou often occurs. At the same time, it is difficult to guarantee the construction quality of the brick holes in the Sanchakou, which seriously affects the overall construction quality and normal production of the pipeline.

Embodiment Construction
[0014] A construction method for lining refractory material masonry at a three-way junction of a process pipeline is completed according to the following steps:
[0015] (1) Hang the line to find the center of the main and branch pipes, determine the exact position of the three-fork composite brick in the main pipe according to the center line of the branch pipe, and then use the center line of the main pipe to position the three-fork in the main pipe on a straight line, repeat After passing the test, build refractory bricks in the lower half ring of all pipelines.
[0016] (2) During the masonry construction of the lower half ring, the brick joints must be controlled within the required size range and the mortar must be full, and the standard roundness should be controlled by the arc-shaped sample ruler, and the roundness of the lower half ring masonry should be guaranteed It cannot be offset from the diameter size and center.
[0017] (3) According to the distribution of th...

The invention relates to a process pipeline divergence lining refractory masonry construction method. In the method, thread drawing determination is utilized to find out a main pipe center and a branch pipe center, and the positions of the pipeline center and all divergence combination bricks are fixed. After lower semiring masonry of the bottom of a pipeline is finished, firstly, a branch pipe section is in masonry extending to the center part of a main pipe section; secondly, in a divergence combination brick section, a rotary tire sleeve is built on a branch pipe rotary tire and is well set; and then the main pipe divergence combination brick part is built, extending forward from one end, thereby finishing masonry operation. Therefore, the invention has the advantages of procedure saving, reduced errors in the construction, convenient operation, high construction efficiency, rapid construction progress, safety, reliability, economy and application.
Description
Technical field: [0001] The invention relates to a construction method for lining a refractory material masonry at a three-way junction of a process pipeline in the iron and steel industry. Background technique: [0002] Process piping with lined refractory masonry is widely used in the steel industry. In engineering construction or maintenance engineering, the progress and quality of lining refractory material masonry at the three-way junction of the process pipeline is the key process to ensure the smooth completion of the entire construction project or emergency repair project. [0003] In the construction of refractory material masonry for the lining of the traditional process pipeline Sanchakou, it is necessary to make the rotary tire in advance with the same shape as the Sanchakou composite brick, and then build the Sanchakou composite brick first, and then build outwards along the three directions of the Sanchakou When the three-way intersection intersects with the r...
