Abstract

The invention discloses a masonry method for a deformed part and a weld joint crossing part of a cylinder. The masonry method comprises the following steps: 1) measuring and confirming the deformed part before masonry; (2) mortar is laid on the cylinder at the deformation position, and bricks are kept horizontal; (3) when the deformation area is built, a wet building mode is adopted, large-surface mortar joints of the fire bricks are kept at 1-1.5 mm, the fire bricks are completely attached to one another, and the large ends of the bricks are attached to the cylinder; wherein when the weld joint is higher than the surface of the kiln cylinder by more than 8mm, the building is carried out after the higher part is polished off; and when the welding seam is within 8mm higher than the kiln cylinder, the bottom of the fire brick is paved with fire clay, so that the brick ring at the welding seam is parallel to the rest brick rings. According to the masonry method for the cylinder deformation and weld joint crossing part, stable positioning of the refractory bricks and the stability of the whole arch ring can be ensured.

Description

technical field [0001] The invention relates to a rotary kiln, in particular to a cylinder body deformation and a masonry method across a welding seam. Background technique [0002] After a period of operation of the rotary kiln, the cylinder body is often deformed due to local high temperature, which brings hidden dangers to the masonry quality. When we masonry deformed and cross-weld parts, we should follow the principle that the horizontal seam of the fire brick is parallel to the kiln axis, and the circumferential seam is perpendicular to the axis and coplanar. [0003] For the masonry of the cylinder body and the raised part of the weld, refractory mud can be directly used to pad the lower part of the brick when it is ≤8mm, so that the refractory bricks can be closely attached to the cylinder body and the refractory bricks on both sides. In principle, the thickness of the refractory mud should not exceed 8mm. If it exceeds 8mm, it will affect the stable positioning of ...
