Method for measuring high furnace burden face appearance and material flow track using laser ranging technique

Abstract

The invention relates to a method for measuring blast burden shape and burden flow trajectory with the laser range-finding technique, which mainly includes the following steps: fetching the point group data in the blast furnace by the laser scanner equipped on the upper part of the blast burden with laser scanning method, rebuilding a three-dimensional model from the point group data by computer, achieving the measurement of blast burden shape, measuring the burden flow trajectory by the two-dimensional laser scanner equipped above the blast burden to form a blanking curve down from the hopper, and integrating the curve with the three-dimensional model by computer, for operators to confirm whether the blanking position is in accordance with the original set position, and according to the result verifying the burden distribution angle and burden turns number. The invention mainly uses the characters that the laser scanner is rapid, stable and accurate and the measurement is not affected by the blast furnace environment, coordinated with the computer process, which can be applied in blast burden investigation of the burden surface after burden distribution and the burden flow trajectory, in order to provide an accurate and practical measure method.

Description

technical field [0001] The invention relates to a method for measuring the shape and flow track of a blast furnace charge surface, in particular to a method for measuring the shape and flow track of a blast furnace charge surface by using laser ranging technology. Background technique [0002] The blast furnace is a complex large-scale chemical reactor, and its reaction process is mainly a series of redox reactions between iron oxide and coke. The efficiency of these chemical reactions depends on the distribution of high-temperature airflow in the blast furnace, and one of the keys to determining the distribution of airflow It lies in the shape and size of the cohesive zone, which is determined by the shape of the material surface. In addition, the position and proportion of the cohesive and iron ore distribution in the furnace will also affect the distribution of the air flow. Therefore, the blast furnace The shape of the material surface and the trajectory of the material ...
