Automatic observing and controlling method for roasting heat accumulating type steel ladle and the device using the method

Abstract

The present invention discloses an automatic measurement and control method for the heating regenerative ladle comprising an automatic measurement and control method for ladle internal lining, an automatic measurement and control method for the smoke and dust density in the flue exhaust and an automatic measurement and control method for flue exhaust temperature. The present invention also discloses an automatic measurement and control method for the heating regenerative ladle comprising an automatic measurement and control method for ladle internal lining, an automatic measurement and control method for the smoke and dust density in the flue exhaust and an automatic measurement and control method for flue exhaust temperature; the present invention can ensure the sufficient burning of fuel and the heating quality of the ladle; the present invention can thoroughly remove the defect that the smoke and dust will pollute the environment and the energy-saving effect is obvious.

Description

Technical field [0001] The invention relates to an automatic measurement and control method for baking a heat storage type ladle and a device used in the method, which is suitable for baking ladle and tundish. Background technique [0002] At present, the baking ladle and tundish usually use manual valves to adjust the flow of fuel and combustion air. The baking temperature is usually monitored by opening the ladle lid to observe the color of the furnace lining, and some use disposable thermocouples to measure the temperature. During the roasting process, the ratio of fuel to combustion-supporting air is generally based on human observation of the color of flue exhaust gas. If black smoke is found, the flow of combustion-supporting air will be increased; currently, the baking ladle and tundish usually have no heat accumulator, and the ladle is high in temperature The gas is directly discharged into the atmosphere through the flue. It can be seen that the traditional baking devic...

AI Technical Summary

Problems solved by technology

It can be seen that the traditional baking device has the following disadvantages: 1. The temperature monitoring and flow adjustment are not accurate during the baking process, which affects the baking quality; 2. The reasonable ratio of fuel to combustion air cannot be guaranteed. If the proportion of combustion air is too low, the fuel cannot Full combustion will not only waste fuel, but also pollute the atmosphere with black smoke from the flue. If the proportion of combustion-supporting air is too high, the heat loss will be large, which will not only waste heat energy, but also reduce the baking temperature; 3. The flue gas temperature is high, and the waste heat cannot be obtained. Utilization, not only wastes heat energy, but also damages air quality; 4. High requirements for operators and heavy workload
