The utility model has simple structure, low cost and simple and easy operation method, and can be used for measuring the abrasion loss and the abrasion part of the front end surface of the blast furnace tuyere.
Description
Technical field
The utility model relates to a kind of a kind of blast-furnace tuyere front end wear measurement device of technical field of blast furnace ironmaking, the measuring apparatus of particularly a kind of blast-furnace tuyere front end abrasion loss and abration position.
Background technology
The air port is easily-consumed products in blast furnace ironmaking production, and is often worn out or burn and cause the air port interim damping down that leaks to change the air port because of the air port, has a strong impact on the normal operation of blast furnace.5 degree because the air port has a down dip; The while out-of-shape; Never have suitable survey instrument and measure the abrasion loss and the abrading section of inlet front end, so blast furnace man author do not understand abrasion loss and the wear law of inlet front end, the air port replacing does not have the data foundation of science; Making that part air port wearing and tearing are less just is replaced, and causes the increase of production cost; And some air port serious wear is not changed timely, causes interim damping down frequent, and this has brought inconvenience not only for the production practice of steel mill, simultaneously, can not fundamentally solve the inlet front end wear problem.
Summary of the invention
The purpose of the utility model is to propose a kind of blast-furnace tuyere front end abrasion amount measuring device; This installs the abrasion loss that appearance not can accurately be measured inlet front end; Can also measure the particular location of abrading section, for changing the air port and solving the data support that the inlet front end wearing and tearing provide science.
For realizing the foregoing invention purpose, the utility model 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 the measurement ring, slide calliper rule and measurement ring are fastenedly connected;
When described slide calliper rule tightened in the part with the blast furnace fresh wind port sidewall projection that does not receive any wearing and tearing, measurement ring and this blast-furnace tuyere front end face were fitted;
Also be provided with crossbeam in the middle of the 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 does not receive any wearing and tearing.
A kind of application method of blast-furnace tuyere front end wear measurement device is characterized in that, this method is:
A, do not receiving select location on the blast furnace fresh wind port of any wearing and tearing; Produce slide calliper rule according to the determined blast-furnace tuyere sidewall profile in this position; Slide calliper rule are when tightening with the blast furnace fresh wind port boss that does not receive any wearing and tearing; Measurement ring and this blast-furnace tuyere front end face are fitted, and slide calliper rule and measurement ring are fastenedly connected;
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, the slide calliper rule and the blast-furnace tuyere boss chucking that worn and torn, slide calliper rule and the applying of air port sidewall;
Distance between C, measurement inlet front end face and measurement ring, this distance is exactly the abrasion loss of inlet front end, through reading the angle index that detects on the corresponding measurement ring in position, can see the abrading section, air port accurately.
Concretely, measurement ring engraves angle index, and the diameter of measurement ring is identical with the diameter at the outstanding position of fresh wind port front end; In the middle of the measurement ring crossbeam can be arranged; Be used for fixing measurement ring, can be connected with slide calliper rule simultaneously yet, at first selection does not receive 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 coincide with the blast furnace fresh wind port sidewall profile that does not receive any wearing and tearing, measurement ring and slide calliper rule are fastened together, and when slide calliper rule tighten, will guarantee the applying of measurement ring and fresh wind port front end face.
After producing blast-furnace tuyere front end wear measurement device according to above-mentioned requirements; When measuring, on the blast-furnace tuyere of existing wearing and tearing, select and the identical position of blast furnace fresh wind port that does not receive any wearing and tearing the part chucking of the blast-furnace tuyere projection of slide calliper rule and wearing and tearing; Slide calliper rule are fitted with wearing and tearing air port sidewall; The abrasion loss of the range observation inlet front end through measurement ring and inlet front end can also draw the angle of abrading section and slide calliper rule according to the scale on the measurement ring, and the 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 often using different lengths and diameter simultaneously of blast furnace; Through the measurement ring of processing different diameter and the slide calliper rule of different size, the combination back just can be convenient for measuring the air port of various size.
The beneficial effect of the utility model is: the utility model is through 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 the abrasion loss and the abrading section in air port, this device is simple to operate; Simultaneously, the design that the utility model can be through size is applicable to the abrasion loss of various inlet front ends and the measurement of abrading section.
