Embodiment Construction

[0028] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0029] A hot repair method for a molten steel tank according to the present invention comprises the following steps:

[0030] 1) if figure 1 As shown, the molten steel tank is in place: the molten steel tank 5 to be repaired is hoisted by the crane and vertically seated on the turning device 4;

[0031] 2) Tank number identification of molten steel tank 5: the label 6 set on the tank body of molten steel tank 5 is automatically identified by the tag reader, and the read information is uploaded to the control system to realize automatic tracking of molten steel tank 5;

[0032] 3) if figure 2 As shown, the molten steel tank 5 is overturned: the molten steel tank 5 is turned over 90° by the overturning device 4, so that the mouth of the tank faces the horizontal direction, and then locked by a mechanical locking mechanism;

[0033] 4) Tank linin...

Abstract

The invention relates to a hot repairing method of a molten steel cylinder. The method comprises the following steps: 1) positioning the molten steel cylinder; 2) recognizing the number of the moltensteel cylinder; 3) overturning the molten steel cylinder; 4) detecting a cylinder lining; 5) positioning a dust collecting cover; 6) starting a dust removing device; 7) positioning a hot repairing spraying gun; 8) treating residual steel; and 9) washing a machine. According to the method, an intelligent system replaces traditional manual operation, so that the working efficiency and the residual steel treating effect are improved; in addition, automatic cylinder lining diagnosing and automatic cleaning functions are provided; and moreover, state pre-warning and defect alarming are realized, sothat major and extraordinarily serious accident can be avoided.

Description

technical field [0001] The invention relates to the technical field of molten steel tank maintenance, in particular to a hot repair method for a molten steel tank. Background technique [0002] The hot repair of molten steel tank is an essential process in the steelmaking process. Usually, the gas and oxygen mixed with high-temperature flame are used to burn and blow the permeable bricks to remove the sundries in the permeable bricks and ensure the normal use of the ladle. The traditional ladle hot repair method is manual operation, which can only simply deal with the residual steel at the nozzle part, with low efficiency, poor controllability, and unsatisfactory cleaning effect. At the same time, a large amount of smoke and dust will be generated during the hot repair of the molten steel tank, which will have a great impact on the environment if it cannot be disposed of in a timely and effective manner.
