A multi-point temperature measurement method for converter body

Abstract

The invention belongs to the technical field of temperature measurement of a converter body, and in particular relates to a multi-point temperature measurement method for a converter body. A bearing seat (7) is arranged under the shaft (6), the trunnion (6) is installed on the bearing seat (7), the bearing seat (7) is placed on the platform, and the converter body (1) passes through the trunnion (6 ) to achieve 360-degree rotation; the taphole temperature measurement point (2), the trunnion temperature measurement point (3), the furnace body temperature measurement point (4) and the furnace bottom temperature measurement point (5) are set on the converter body (1) ;Measure and record the temperature values ​​of each temperature measurement point by using a hand-held portable thermometer; make statistics and summary of the measured temperature values ​​of each temperature measurement point, obtain the temperature of the converter body, and complete a measurement cycle.

Description

technical field [0001] The invention belongs to the technical field of temperature measurement of a converter body, and in particular relates to a multi-point temperature measurement method for a converter body. Background technique [0002] In order to solve the existing converter smelting conditions, since the converter is built with refractory materials, it will be eroded unevenly by steel, slag and oxygen during the smelting process. [0003] At present, the measures of slag splashing to protect the furnace and repairing the furnace have a certain maintenance effect; however, there will still be local thinning of the refractory material in the furnace, and the weak parts cannot be seen from the outside of the furnace shell by the naked eye due to the influence of high-temperature flue gas. Weak parts can easily cause molten steel to pass through the furnace body, causing the converter to be shut down for maintenance, which greatly affects the life of the furnace body and...

Problems solved by technology

[0002] In order to solve the existing converter smelting conditions, due to the refractory materials in the converter furnace, during the smelting process, the erosion caused by steel, slag and oxygen is uneven.

[0003] At present, the measures of slag splashing to protect the furnace and repairing the furnace have a certain maintenance effect; however, there will still be local thinning of the refractory material in the furnace, and the weak parts cannot be seen from the outside of the furnace shell by the naked eye due to the influence of high-temperature flue gas. Weak parts can easily cause molten steel to pass through the furnace body, causing the converter to be shut down for maintenance, which greatly affects the life of the furnace body and smooth production
