Tundish baking and protecting system and method

Abstract

The invention discloses a tundish baking and protecting system. The system comprises a baker, a tundish arranged below the baker, and a PLC. The baker comprises burners, a coal gas branch pipe and anair branch pipe. The multiple burners are arranged in the length direction of the tundish in a spaced and centered manner. An electronic igniter and a flame detector are arranged in each burner. The burners communicate with the coal gas branch pipe. The coal gas branch pipe is provided with a coal gas flow detector, a coal gas check valve and a coal gas flow adjusting valve. The burners communicate with the air branch pipe. An air flow detector, an air check valve and an air flow adjusting valve are arranged on the air branch pipe. All the detectors, all the valves and all the electronic igniters are connected with the PLC. The system has the beneficial effects that the protecting system can be used for protection for the overhauling mode and the baking mode, and safety control under all working states of a baking area of the tundish is effectively ensured.

Description

technical field [0001] The invention relates to the technical field of tundish baking in the iron and steel industry, in particular to a tundish baking protection system and method. Background technique [0002] The main function of the tundish roaster is to roast the tundish, which is an important part of the entire continuous casting production process and one of several key quality control points. At present, tundish baking is generally operated manually, and there is also a lack of monitoring for the baking process and maintenance conditions. The main problems are as follows: manual ignition, there are potential safety hazards; during the tundish baking, whether there is personnel There is no effective monitoring and reminder when entering the baking area; whether there is gas leakage in the system is unpredictable; whether the gas content exceeds the standard, whether the equipment in the tundish area can be repaired cannot be judged; whether various valves are installe...

AI Technical Summary

Problems solved by technology

At present, tundish baking is generally operated manually, and there is also a lack of monitoring for the baking process and maintenance conditions. The main problems are as follows: manual ignition, there are potential safety hazards; during the tundish baking, whether there is personnel There is no effective monitoring and reminder when entering the baking area; whether there is gas leakage in the system is unpredictable; whether the gas content exceeds the standard, whether the equipment in the tundish area can be repaired cannot be judged; whether the various valves are installed and closed normally lacks detection

However, there is currently no effective system for how to ensure the safety of tundish baking
