Description
Technical field
The present invention relates to a kind of a kind of blast-furnace tuyere front end wear measurement device of technical field of blast furnace ironmaking, particularly the measuring apparatus of a kind of blast-furnace tuyere front end abrasion loss and abration position.
Background technology
In blast furnace ironmaking production, air port is easily-consumed products, often worn out because of air port or burn and cause the air port interim damping down that leaks to change air port, has a strong impact on the normal operation of blast furnace.Due to air port 5 degree that have a down dip, the while out-of-shape, never have suitable survey instrument and measure abrasion loss and the abrading section of inlet front end, therefore blast furnace man author does not understand abrasion loss and the wear law of inlet front end, tuyere replacement does not have the data foundation of science, make that part air port wearing and tearing are less just to be replaced, cause the increase of production cost; And some air port serious wear is not changed timely, cause interim damping down frequent, this has brought inconvenience not only to the production practice of steel mill, simultaneously, can not fundamentally solve the inlet front end wear problem.
Summary of the invention
The object of the invention is to propose a kind of blast-furnace tuyere front end abrasion amount measuring device, this device not only can accurately be measured the abrasion loss of inlet front end, can also measure the particular location of abrading section, for changing air port and solving the Data support that the inlet front end wearing and tearing provide science.
For achieving the above object, the present invention has adopted following technical scheme:
A kind of blast-furnace tuyere front end wear measurement device, it is characterized in that: this device comprises slide calliper rule and measurement ring, and angle index is arranged on measurement ring, slide calliper rule and measurement ring are fastenedly connected;
Described slide calliper rule are when the part chucking of the blast furnace fresh wind port sidewall projection with not being subject to any wearing and tearing, and measurement ring and this blast-furnace tuyere front end face are fitted;
Also be provided with crossbeam in the middle of described measurement ring;
The diameter of described measurement ring is identical with the diameter at the outstanding position of the fresh wind port front end that is not subject to any wearing and tearing.
A kind of application method of blast-furnace tuyere front end wear measurement device, is characterized in that, the method is:
A, be not subject to select location on the blast furnace fresh wind port of any wearing and tearing, go out slide calliper rule according to this position determined blast-furnace tuyere sidewall shape fabricating, when slide calliper rule tighten at the blast furnace fresh wind port boss with not being subject to any wearing and tearing, measurement ring and the laminating of this blast-furnace tuyere front end face, be fastenedly connected slide calliper rule and measurement ring;
B, the above-mentioned measuring apparatus of making being placed on the blast-furnace tuyere that weares and teares, and guaranteeing this position and steps A) selected position is identical, and slide calliper rule are fitted with the air port sidewall with the blast-furnace tuyere boss chucking that worn and torn, slide calliper rule;
Distance between C, measurement inlet front end face and measurement ring, this distance is exactly the abrasion loss of inlet front end, by reading the angle index detected on measurement ring corresponding to position, can see accurately the abrading section, air port.
Concretely, measurement ring engraves angle index, the diameter of measurement ring is identical with the diameter at the outstanding position of fresh wind port front end, in the middle of measurement ring, crossbeam can be arranged, for the fixation measuring ring, also can be connected with slide calliper rule simultaneously, at first selection is not subject to arbitrary position of the blast furnace fresh wind port of any wearing and tearing, can produce the shape of slide calliper rule according to this position, make slide calliper rule shape with the blast furnace fresh wind port sidewall profile that is not subject to any wearing and tearing, coincide, measurement ring and slide calliper rule are fastened together, and will guarantee measurement ring and the laminating of fresh wind port front end face when slide calliper rule tighten.
After producing blast-furnace tuyere front end wear measurement device according to above-mentioned requirements, when measuring, select the position identical with the blast furnace fresh wind port that is not subject to any wearing and tearing on the blast-furnace tuyere of existing wearing and tearing, the part chucking of the blast-furnace tuyere projection of slide calliper rule and wearing and tearing, slide calliper rule and the sidewall laminating of wearing and tearing air port, the abrasion loss of the range observation inlet front end by measurement ring and inlet front end, can also draw the angle of abrading section and slide calliper rule according to the scale on measurement ring, abrading section is accurately located.Two parts of measurement ring and slide calliper rule can also be convenient for measuring the air port of different size, the on-the-spot air port of different lengths and diameter of often simultaneously using of blast furnace, by the measurement ring of processing different diameter and the slide calliper rule of different size, after combination, just can be convenient for measuring the air port of various size.
The invention has the beneficial effects as follows: the present invention is by simple structure design, profile standard measuring equipment customized according to the blast furnace fresh wind port, use this measuring apparatus to measure the blast-furnace tuyere that worn and torn, can accurately measure abrasion loss and the abrading section in air port, this device is simple to operate, simultaneously, the present invention can pass through the design of size applicable to the abrasion loss of various inlet front ends and the measurement of abrading section.
