Abstract

The invention relates to ferrous metallurgy, namely to instrumentation technology in the rolling industry. The purpose of the invention is to provide a uniform calibration dependence. To do this, the measuring elastic element 5, which is a body 4 with a dual-console beam 12 of equal resistance fixed in it, additionally establishes a lower yoke 7 with spring-loaded movable stops 14 located in it, which allows you to adjust the pre-stress of the two-console beam 12. 2 silt .

Description

WITH

The invention relates to ferrous metallurgy, in particular to instrumentation engineering, and can be used to measure rolling forces.

The purpose of the invention is to provide a uniform calibration dependence and simplify the interpretation of measurement results.

FIG. 1 shows the proposed device, a general view; in fig. 2 - the same, longitudinal section.

On the object under study, for example, a rolling mill, between the cushion 1 of the upper roll and the pressure screw 2 with the support 3, a case 4 of the force measuring device is installed with windows cut into it, into which a removable elastic measuring element 5 consisting of a case containing ( Fig, 2) the upper 6 and lower 7 traverse

and two cheeks 8, on which the sleeves 9 are fixed, limiting the movement of the upper crosshead 6, which through the movable stops 10 fixed by locknuts 11. rests on a dual console beam 12 of equal resistance fixed by a screw 13 on the lower cross bar 7 provided with spring-loaded movable stops 14 with springs 15 with lock nuts 16.

PRI me R. The frame 500 is used to measure the power parameters of the rolling profiles. During the scheduled stopping of the mill, on all the cages between the cushions of the upper rolls and the pressure screws, the housings of the force measuring devices, which are fixed on the cushions of the upper rolls, are installed. Before installing the device for measuring forces, they are calibrated on a 2GP-250 hydraulic press;

each case is calibrated for the entire batch of removable elastic measuring elements in order to obtain a unified calibration dependence and the possible replacement of outdated elements without additional calibration. When calibrating by moving up the movable lugs 10 of the upper crosshead, coarse adjustment of the pre-stress of the dual console beam 12 is carried out, and more precise adjustment is carried out by spring-loaded movable stops 14 of the lower crosshead to ensure uniform calibration and reduce labor intensity when deciphering the obtained results. Thus, the use of the proposed change in the design of the elastic element

Comparing with the prototype, it allows to obtain the same calibration schedules for the entire batch of elastic elements and will speed up the process of decoding the results by 2-4 times.
