为确保正确的安装冷风套和窑口护板，先确定回转窑筒体外壁和冷风套内壁的安

In order to ensure the correct installation of the cold air jacket and the kiln mouth guard, first determine the installation location of the outer wall of the rotary kiln shell and the inner wall of the cold air jacket. Then, according to the rotation direction of the rotary kiln, the support base is welded to the inner wall of the cold air jacket, about one meter is welded. In order to make the cold air jacket mainly bear the tensile force, the spring plate is welded to the outer wall of the rotary kiln evenly. The welding rod is J506. Note: When welding, the requirements of the welding seam are smooth, and there should be no defects such as pores and slag inclusions. If it is found that it must be repaired in time; the surface of the welding seam should not have a series of defects such as cracks, pores, slag and under-welding. Welding quality.

To ensure the correct installation of cold air cover and kiln guard, first determine the outer wall of the rotary kiln barrel and the inner wall of the cold air sleeve installation position. Then according to the rotation direction of the rotary kiln will be welded support seat on the inner wall of the cold air sleeve, about 2 meters or so welded one, in order to allow the cold air sleeve to bear the main pull force, the spring plate is evenly welded on the outside wall of the rotary kiln, the welding rod using J506. Note: Welding weld requirements for smooth, can not have pores such as slag defects, such as if found must be repaired in a timely manner, weld surface should not have cracks, pores, slag and unwelded through a series of defects, to ensure the quality of welding.

In order to ensure the correct installation of the cold air sleeve and the kiln mouth guard board, first determine the installation position of the outer wall of the rotary kiln shell and the inner wall of the cold air sleeve. Then according to the rotation direction of the rotary kiln, the support seat is welded on the inner wall of the cold air sleeve, about 2 meters. In order to make the cold air sleeve bear the main tension, the spring plate is welded on the outer wall of the rotary kiln evenly, and the welding rod is j506. Note: during welding, the weld shall be smooth and free of defects such as porosity and slag inclusion. If found, it shall be repaired in time. The weld surface shall be free of cracks, porosity, slag, incomplete penetration and other defects to ensure the welding quality.
