An automatic temperature measurement and sampling system for molten steel in a steelmaking converter

Abstract

The invention relates to a stokehold automatic temperature measuring and sampling system for steelmaking converter molten steel. The system comprises a stokehold automatic temperature measuring and sampling part, a casing automatic assembling and disassembling part and a system electric control part. The casing automatic assembling and disassembling part comprises a robot and a gripper of the robot, a casing cartridge, a liquid steel sample, a waste casing collection warehouse and a machine vision system. The machine vision system measures the head position of an actual temperature measuring gun and / or a sampling gun, calculates the deformation amount of the temperature measuring gun and / or the sampling gun head by comparing the head position with preset coordinates of the temperature measuring gun and / or the sampling gun, and provides the deformation amount to the robot, so that the robot can control the displacement of the gripper according to the deformation amount and casings are accurately installed. In the process of automatic temperature measurement and sampling, a converter is turned to a certain angle for temperature measurement and sampling, thereby avoiding a conventional way that automatic temperature measuring needs to be completed by vertical insertion from a converter mouth.

Description

technical field [0001] The invention relates to an automatic temperature measurement and sampling system in front of molten steel in a steelmaking converter, and relates to the structural design and development of a robot and a machine vision system applied to temperature measurement and sampling of molten steel in a furnace, and casing automatic armor. The system can replace manual work of temperature measurement and sampling, and belongs to the field of design and development of intelligent and automatic equipment and its application in smelting systems. Background technique [0002] At present, there are imported equipment for automatic temperature measurement and sampling of large-tonnage converters, and their working method is to vertically insert into the converter from the top of the converter mouth for temperature measurement and sampling. The imported equipment requires a large investment, and a large-scale transformation of the converter is required to install and ...

AI Technical Summary

Problems solved by technology

[0003] During the temperature measurement and sampling process of the automatic temperature measurement and sampling system, there are several problems in the following aspects: When the temperature measurement sleeve is installed in the temperature measurement gun, the insertion dimensional accuracy is high, and the thermocouple at the head of the sleeve will be damaged if it is too deep. If it is too shallow, the contact point will not be touched, and the temperature signal cannot be transmitted to the transmitting device, and it is difficult to achieve this high-precision insertion size control in the existing technology; The outer diameter of the temperature measuring gun and the sampling gun has a small difference, and the accuracy of the alignment and installation of the sleeve and the gun is high; the head of the temperature measuring gun and the sampling gun is easy to bend and deform, and under a certain amount of deformation, the casing and the gun head Difficult to install accurately; there is a certain range of changes in the outer diameter of the temperature measurement sleeve, temperature protection sleeve and sampling sleeve, which cannot be reliably grasped

Due to manual operation, the temperature measurement and sampling points in the furnace are different every time, and the results are unstable and fluctuate greatly
