Problems solved by technology

However, due to the limitation of the length of the thermocouple, it can only measure the temperature of the furnace gas near the ladle cover; the density of the hot gas is small and floats up, which makes the temperature distribution of the furnace gas in the ladle uneven; The method cannot accurately measure the temperature of the inner wall of the ladle

Abstract

The invention relates to the temperature measurement field of a high temperature furnace in steel and colored metallurgy industry, in particular to a method and a device for rapidly and accurately detecting and controlling the baking temperature of a ladle. The method and the device are characterized in that a dotty temperature value of the outer surface of the ladle is measured by an infrared temperature measurement instrument, the temperature value of each point of the inner surface of the ladle is calculated by a heat transfer model, the transient temperatures of the inner surface of the ladle at the different depths are calculated by the temperature of the outer surface of the ladle and a convection radiation heat transfer coefficient, a baking air-fuel ratio is adjusted by a proportion integration differentiation (PID) temperature feedback controller so as to realize the automatic baking of the ladle; when the transient temperatures in the ladle reach target values, a heat insulation program is automatically transferred. Compared with the previous technology, the method and the device provided by the invention have beneficial effects that the structure is compact, simple and reasonable, and easy to operate, the temperature measurement environment of the ladle baking is greatly improved, and the service life of the temperature measurement instrument is lengthened, and simultaneously, the accuracy of the temperature measurement is improved, so that a basic data is provided for the accuracy control of thermal regulation of the ladle baking.

Description

technical field [0001] The invention relates to the field of temperature measurement of high-temperature furnaces and kilns in iron, steel and nonferrous metallurgy industries, in particular to a method and device for quickly and accurately detecting and controlling the baking temperature of a ladle. Background technique [0002] The ladle is a container for storing molten steel and an integral part of refining equipment. It is responsible for multiple tasks such as receiving, refining and transporting molten steel. In addition to assessing whether the design parameters of the ladle meet the requirements of the previous and subsequent processes in the process, the ladle baking temperature is an important factor to ensure the quality of the ladle and affect the production cost of the steelmaking workshop and the quality of molten steel. [0003] Studies have shown that increasing the temperature of the inner wall of the ladle before tapping can reduce the temperature drop of ...
