When measurement is carried out, the handle is held, the inspection face is made to make contact with the inspected face of the water filling opening, and measurement is carried out by rotating the tool along the side face of the water filling opening with the pore diameter of the water filling opening as a center. The water filling opening inspection tool has the advantages of being simple in operation, accurate in measurement, and capable of ensuring the accurate matched size between the water filling opening and an installation board of a steel ladle base.

Description

A kind of filling pipe end instruments of inspection

Technical field

The utility model relates to a kind of filling pipe end instruments of inspection, belongs to refractory material inspection machine technical field.

Background technology

Metallurgy industry, the slide gate nozzle that steel-making is used is comprised of brick cup, filling pipe end, upper slide, lower skateboard and the lower mouth of a river, filling pipe end the first half is contained in lower brick cup, and the latter half is contained in refractory brick and in ladle base installing plate, and the end opening of filling pipe end is connected with upper slide orifice.In ladle, molten steel can flow out by brick cup, upper nozzle brick, upper slide, lower skateboard, the lower mouth of a river, waters steel operation.

If be combined with deviation between the filling pipe end of producing and ladle base baffle; can cause filling pipe end to install not in place; cannot guarantee that filling pipe end mother-son mouth end face and ladle base skateboards slot baseplane dress is flat, easily cause between filling pipe end fracture, filling pipe end and upper slide the serious accidents such as badly bleeding.

At present; the check of filling pipe end does not have special instrument; traditional metering system is all used slide measure to take multiple measurements filling pipe end; can determine that whether this fit dimension is qualified; because filling pipe end is designed with R angle, slide measure is difficult for location, measures inconvenient; measurement result is not accurate enough, causes being combined with deviation between filling pipe end and ladle base baffle.

Utility model content

The utility model object is to provide a kind of filling pipe end instruments of inspection, measures accurately, and the check of being more convenient for guarantees that between filling pipe end and ladle base installing plate, fit dimension is accurate, solves the problem existing in background technology.

The technical solution of the utility model is:

A kind of filling pipe end instruments of inspection, comprise handle and check face, check face is positioned at the corresponding surface of handle, described check bread is containing tolerance section, horizontal segment, vertical section, oblique line section A, angle R and oblique line section B, between oblique line section A and oblique line section B, be provided with angle R, vertical section and horizontal segment are arranged vertically, between be provided with gap, vertical section and horizontal segment end are provided with tolerance section, and check face shape and filling pipe end match.

Described check face size is verified face with filling pipe end and matches.

During measurement, hold handle, measured of check face and filling pipe end are contacted, centered by filling pipe end aperture, along filling pipe end side surface rotary, measure.

The beneficial effects of the utility model are: the one, to make simply, and machining accuracy is high, and applicability is strong, can be according to the instruments of inspection of different upper nozzle brick type design different sizes; The 2nd, simple to operate, measure accurately, dimensional tolerance, R angle are designed on the instruments of inspection, the check of being more convenient for, guarantees that between filling pipe end and ladle base installing plate, fit dimension is accurate; The 3rd, in filling pipe end installation process, guarantee that filling pipe end coordinates accurately with ladle base installing plate, prevent that filling pipe end from tilting, cause unbalance stress in use procedure, there is badly bleeding accident.

Accompanying drawing explanation

Fig. 1 is the utility model front view;

Fig. 2 is that the utility model is used view;

In figure: handle 1, tolerance section 2, horizontal segment 3, vertical section 4, oblique line section A5, angle R6, oblique line section B7, filling pipe end 8.

The specific embodiment

Below in conjunction with accompanying drawing, by example, the utility model is described in further detail.

With reference to accompanying drawing 1,2, a kind of filling pipe end instruments of inspection, comprise handle 1 and check face, check face is positioned at the corresponding surface of handle, described check bread is containing tolerance section 2, horizontal segment 3, vertical section 4, oblique line section A5, angle R6 and oblique line section B7, between oblique line section A5 and oblique line section B7, be provided with angle R6, vertical section 4 is arranged vertically with horizontal segment 3, between be provided with gap, vertical section 4 is provided with tolerance section 2 with horizontal segment 3 ends, check face shape and filling pipe end 8 match, and size is verified face with filling pipe end 8 and matches, and tolerance section 2, angle R6 make according to standard or drawing requirement.

The course of work: during measurement, hold handle 1, the check face of making contacts with measured of filling pipe end, centered by filling pipe end aperture, along filling pipe end side surface rotary, measure, whether fit at measured angle of viewing angle R and filling pipe end, if by adjusting tolerance section 2, measured of filling pipe end all can be fitted with measurement face, and measured of filling pipe end is qualified.If measured end face out-of-size section 2, is considered as defectively, need to change new die base again.

Claims (2)

1. the filling pipe end instruments of inspection, it is characterized in that comprising handle (1) and check face, check face is positioned at the corresponding surface of handle, described check bread is containing tolerance section (2), horizontal segment (3), vertical section (4), oblique line section A(5), angle R(6) and oblique line section B(7), oblique line section A(5) and oblique line section B(7) between be provided with angle R(6), vertical section (4) is arranged vertically with horizontal segment (3), between be provided with gap, vertical section (4) is provided with tolerance section (2) with horizontal segment (3) end, and check face shape and filling pipe end (8) match.

2. the filling pipe end instruments of inspection according to claim 1, is characterized in that described check face size matches with filling pipe end (8) face of being verified.
