Embodiment 1

[0050] Such as figure 1The longitudinal sectional view of the charge surface of the blast furnace is shown. The blast furnace includes a furnace body, a small inspection manhole 4 arranged on one side above the furnace body and a large inspection door 1 on the other side; the internal charge surface of the blast furnace includes a charge surface platform 2 and a charge surface The surface center funnel 3; the inner diameter D of the blast furnace is 5050 mm, which is the radius of the blast furnace charge surface.

[0051] Such as figure 2 Shown is the measuring device used in this embodiment, including a long rod-shaped measuring device body 5, a pulley 6 fixedly arranged at one end of the measuring device body, a steel wire rope 7 arranged along the measuring device, passing through the pulley, and a wire rope 7 arranged at one end of the steel wire rope 7. Heavy hammer 8.

Embodiment 2

[0065] This embodiment also takes figure 1 Take the measurement of the blast furnace material level as an example, using such as image 3 The measuring device shown is different from Embodiment 1 in that the pulley 6 and the measuring device body 5 can slide relatively, and one end of the pulley 6 is provided with a moving pole 9 extending along the length of the measuring device body.

[0066] A method for measuring the shape of a charge surface of a blast furnace, comprising the steps of:

[0067] 1) if image 3 As shown, the preparation of the measuring tool is to process a long rod-shaped measuring device. A pulley that can move relative to the measuring device body is arranged on the measuring device. The wire rope with the weight is arranged along the measuring device, passes through the pulley, and makes the weight fall vertically;

[0068] 2) if Figure 8 As shown, install the measuring device, open the small manhole for blast furnace maintenance, and extend one en...

Embodiment 3

[0079] Same as Example 1, the difference is: when adjusting the horizontal position of the entire measuring device in steps 3), 6), and 7), the measuring device can be detachably fixed to the fixed point at one end of the blast furnace and move together, that is, when adjusting, Move and adjust the whole measuring device and the bracket that is fixed by bolts to support the measuring device; The change of the length of the device body protruding into the blast furnace will lead to changes in the size of the bending deformation. In order to avoid changes in the front and rear bending deformation, the bracket supporting the measuring device is moved together so that the bending deformation of the measuring device body does not change before and after the movement. , which can also effectively offset the error caused by bending deformation and improve the measurement accuracy.

Abstract

The invention discloses a method for measuring the shape of a charge surface of a blast furnace, which belongs to the field of blast furnace measurement, and solves the problems of low visual accuracy and high cost of laser measurement in the existing blast furnace charge surface measurement. The method of the present invention has the following steps: preparation of measuring tools; installation of measuring devices; by adjusting different positions of the measuring devices, measuring and marking the positions of these different positions relative to a fixed point of the blast furnace, converting the marked points into distances, and combining the parameters of the blast furnace itself , calculate the depth of the blast furnace center funnel and the width of the material surface platform. The invention can complete the measurement of the charge level of the blast furnace at relatively low cost, has accurate measurement data, and plays a powerful guiding role in charging the charge of the blast furnace.

Description

technical field [0001] The invention belongs to the field of blast furnace measurement, and in particular relates to a method for measuring the shape of a blast furnace material surface. 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. Such as figure 1 As shown, a longitudinal section view of a charge level of a blast furnace, wherein the shape of the charge level includes a charge level platform and a center funnel of the charge level. In order to obtain the required information in the furnace, people have used in...
