Problems solved by technology

If re-repair is carried out, the dipping tube must be cut off and a new dipping tube must be reinstalled, which not only wastes costs, affects the age of the tube and tank, but also leads to unplanned slotting methods, which seriously affects production

Embodiment Construction

[0012] Such as figure 1 As shown, a method for repairing a circulation pipe, the lower end of the circulation pipe 2 is connected with an immersion pipe 1, and includes the following steps: A. Insert a steel drum 3 into the lumen of the circulation pipe 2 and the immersion pipe 1, and the steel drum 3 barrels There is a gap between the wall and the inner wall of the immersion pipe 1 and the inner wall of the circulation pipe 2; B. The gap between the steel drum 3 and the immersion pipe 1 is plugged with asbestos fiber 6; C. The repair material is 13-16 by weight: 100 is mixed and stirred into a fluid, and then the fluid repair material is pressed into the gap 4 between the barrel wall of the steel barrel 3 and the inner wall of the dip tube 1; D, the repair material is sintered by curing, natural evaporation and baking. The wall tiles falling off 5 of the circulation pipe 2 are filled with fire mud.

[0013] The method of the present invention was tested in Baosteel Company. After...

Abstract

The invention discloses a method of repairing a circumfluence pipe; the lower end of the circumfluence pipe is connected with a dipping pipe; the repairing method is characterized in that the method includes the following steps: A. a steel cylinder is inserted into the pipe cavities of the circumfluence pipe and the dipping pipe; gaps are maintained between the cylinder wall of the steel cylinder and the inner wall of the dipping pipe; B. the gaps between the steel cylinder and the dipping pipe are filled with asbestos fiber; C. the repairing fillers are filled into the gaps between the cylinder wall of the steel cylinder and the inner wall of the dipping pipe; D. the repairing fillers are sintered. The method of repairing a circumference pipe can improve the average pipe service life and reduce the damage of the dipping pipe due to the replacement of the circumfluence pipe.

Description

Technical field [0001] The invention relates to a method for repairing a circulation pipe. Background technique [0002] The vacuum tank is composed of an upper tank, a lower tank and a dip tube. The immersion pipe is connected with the circulation pipe at the bottom of the lower tank. Because the dip tube is directly inserted into molten steel, it melts quickly, so it must be separated and replaced during use. When the immersion pipe is replaced, the refractory bricks of the circulation pipe will fall off irregularly. Use unshaped refractory materials such as fire mud, plastics, etc. to fill, and only 10-20 furnaces can be used. After the stuffing material is washed clean, it can only be maintained by gunning. If re-mending is implemented, the dip tube must be cut off and a new dip tube must be reinstalled. This will not only waste cost, affect the tube age and tank age, but also lead to unplanned slotting methods, which seriously affects production. Summary of the invention ...
