Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0026] see figure 1 Generally, the blast furnace 1 is in a shape that is centrosymmetric along the central axis L, and the charge surface 2 of the charge therein is generally also in a shape that is approximately centrosymmetric along the central axis L. exist figure 1 In the cross-sectional view of , this central symmetry appears as left-right axisymmetric along the axis L.

[0027] exist figure 1 In the illustrated embodiment, the system for online measurement of blast furnace charge level of the present invention includes a laser 3 and a camera 5 arranged above the charge level 2 . The position and / or arrangement of the laser 3 and the camera 5 on the blast furnace 1 can be conventional, as in Chinese patent ZL200610089415.6.

[0028] The laser 3 emits a laser beam 4 which is “visible” to the camera 5 . It should be noted that...

Abstract

The invention discloses a system and a method for measuring blast furnace burden surface on line so as to detect blast furnace burden surface information. The system provided by the invention comprises a laser disposed over the burden surface. The laser emits laser beams which can continuously scan at least a part of the burden surface. A photography instrument is used for shooting the burden surface image which contains detecting point patterns formed by the emission of the laser beams on the burden surface. An image processing device receives the burden surface image output from the photography instrument and outputs the burden surface information. In comparison with the prior art, the method provided by the invention can be used to greatly reduce the system cost and obtain burden surface information which more conforms to reality by obtaining a lot of actual detecting points. In addition, as the system for measuring blast furnace burden surface on line can require fewer lasers (even one laser), the method has more advantages in the aspect of system miniaturization and can simplify protection measures of the laser.

Description

technical field [0001] The present invention generally relates to the field of blast furnace measurement, and more particularly relates to a system and method for online measurement of blast furnace material level. Background technique [0002] Smelting blast furnaces usually operate in a closed state, and have an environment such as high temperature, high pressure, high dust, and high humidity. Therefore, the operator cannot directly observe the information in the furnace, such as the material level of the furnace material, the charging process, the operating status of the equipment in the furnace, etc., but can only infer from the values ​​​​of conventional detection instruments such as temperature, pressure, and flow. [0003] In order to obtain the required information in the furnace, people have used infrared scanning and microwave scanning to detect the interior of the blast furnace, but these detection methods require the use of complex detection and receiving devices...
