Problems solved by technology

Due to the large amount of data, the two data cannot be mixed and calculated. In addition, due to the limitation of the accuracy of the measuring instrument, the change point cannot be directly measured. Factors such as long measurement time and manual measurement will affect the accuracy of the measurement results.

Embodiment Construction

[0027] The specific embodiment of the present invention will be further described below in conjunction with accompanying drawing:

[0028] Taking the deformation measurement of No. 10 blast furnace in a steel plant as an example, the specific operation steps are as follows:

[0029] 1) Select four pillars (No. 1, No. 2, No. 3, and No. 4 pillars) and a crane beam on the foundation of the blast furnace as deformation observation objects, and illustrate by observing the deformation of the four pillars and a crane beam Deformation of blast furnace body;

[0030] 5 ground control points are arranged on the blast furnace ground: B1, B2, B3, B4, B5. See figure 1 ; Ground control points are marked on the concrete floor with steel nails. Each ground control point should meet the requirements of the plane method and the elevation method respectively. , that is, point B1 observes the inclination of column No. 1, point B2 observes the inclination of column No. 2, point B4 observes the ...

Abstract

The invention belongs to the field of deformation measurement of buildings and structures, and in particular relates to a method for observing the deformation of a blast furnace. The method for observing the deformation of the blast furnace is characterized in that deformation observing points are respectively set on a brace and a crane beam representing the basic deformation of the blast furnace for using as deformation observing objects for reflecting the incline degree of the furnace body, with the aid of a laser total station and a leveling instrument, the measurement is respectively performed by the planar method and the elevation method, and then the arithmetic mean value of the two measurement results are used as the deformation of the blast furnace. Compared with the prior art, the method for observing the deformation of the blast furnace has the beneficial effects that (1) the cost is saved, the investment is reduced, and important actual guiding significance is provided; (2) reference is provided for the optimal design of the blast furnace; (3) influence of environment, pressure, temperature and atmospheric refraction on the measurement is reduced; and (4) the evaluation of the blast furnace is much closer to the real situation.

Description

technical field [0001] The invention belongs to the field of measuring the deformation of the ironmaking blast furnace foundation, and in particular relates to a method for observing the deformation of the blast furnace. Background technique [0002] With the development of society and economy, in the process of technological upgrading in the iron and steel industry and the transformation of old blast furnaces, it is necessary to analyze the stability and operation posture of blast furnaces, evaluate the health status of blast furnaces, and inspect the design quality, construction quality and Detect the stability and safety of the blast furnace during production and operation. During normal production and operation, analyze the state of the blast furnace: such as the deformation at no-load and full load, determine the loading of the blast furnace, and ensure production safety. It can also be used to evaluate its stability and analyze the value of use when renovating old buil...
