A tundish baking protection system and method

Abstract

The invention discloses a tundish roasting protection system, which comprises a roaster, a tundish arranged under the roaster, and a PLC controller. The roaster includes a burner, a gas branch pipe and an air branch pipe. There are multiple burners, which are arranged at intervals along the length of the tundish; the burners are equipped with electronic igniters and flame detectors, and the burners are connected to gas branch pipes; gas flow detectors, gas A cut-off valve and a gas flow regulating valve; the burner is connected to the air branch pipe; an air flow detector, an air stop valve and an air flow regulating valve are arranged on the air branch pipe; each detector, each valve and the electronic igniter are respectively Connect with PLC controller. The beneficial effects of the present invention are: the protection system can be used for protection in the two modes of inspection mode and baking mode, effectively ensuring the safety and control of each working state in the tundish baking area.

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...

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
