A device for measuring the internal dimensions of a steel ladle using a laser range finder and its operating method

Abstract

The invention relates to a device for measuring the inner dimension of a steel ladle by using a laser distance measuring instrument and an operation method thereof, comprising a laser distance measuring mechanism and a beamline mechanism, and a lateral barrier frame is arranged at the bottom of the laser distance measuring mechanism. The beneficial effects of the present invention are: the device and its operating method for measuring the internal dimensions of the steel ladle by using a laser rangefinder can measure the size of any area inside the steel ladle through the method of the invention, and compare it with the relevant parameters when the ladle goes online to determine the The degree of regional melting loss can be measured by this method to easily simulate the internal situation of the ladle, measure and calculate the degree of melting loss of the refractory material of the ladle and the steel quantity of the ladle. Monitor and provide ladle lining size control data and information to lay the foundation for saving refractory consumption and increasing ladle life, and effectively prevent major accidents of ladle through furnace, and escort the safe operation of ladle ladle service and smooth production.

Description

technical field [0001] The invention relates to the technical field of steelmaking, in particular to a device for measuring the internal dimensions of a steel ladle by using a laser range finder and an operation method thereof. Background technique [0002] At present, the internal size measurement tool of the ladle is the LTG ladle lining measuring instrument. The measuring principle is: by emitting a pulsed laser beam to the lining surface of the steel ladle to be tested, and receiving the returned laser to measure its flight time, and then calculate it according to the transmission speed of the laser. The distance between the device and the target point. When measuring, the user pushes it to a certain position on the platform in front of the ladle. After the equipment performs rapid self-positioning, it can start to scan and measure the target area of ​​the ladle. During the measurement, the laser head of the equipment rotates at a certain step angle. By quickly changing...

AI Technical Summary

Problems solved by technology

[0003] Ordinary equipment has high measurement costs and high daily maintenance costs. A laser rangefinder costs about 1 million yuan, and the monthly maintenance cost is about 10,000 yuan. However, there is a measurement method in the prior art that is a pole structure measurement method. This tool It is composed of an upper pole and a lower pole. The front ends of the upper pole and the lower pole are respectively equipped with symmetrically inclined measuring feet, and the rear ends of the upper pole and the lower pole are respectively equipped with symmetrically inward inner angle measuring plates. The lengths of the rods are equal, and the hinge points of the second half are hinged to each other through the hinged device, which has the disadvantage of heavy measuring equipment, which requires 4 to 5 people to operate at the same time during the measurement, and the measurement accuracy is low
