Description

A kind of inspection device of mill roll-gap

Technical field

This utility model relates to checking device, more particularly, it relates to the inspection device of a kind of mill roll-gap.

Background technology

The technological process of hot rolling line substantially has heating, roughing, finish rolling, batches the operations such as whole.As it is shown in figure 1, first According to rolling scaduled, slab is loaded walking beam furnace 1 according to order, slab be heated to the target temperature of process stipulation with After, by taking out steel machine, slab is extracted out successively, be placed on charging roller table, then hot slab is transported to roughing mills.In roughing Unit, slab initially enters R1 two roller reversible milling train 2 and rolls 1-3 passage.Then slab entrance R2 four-high reversing mill 3 rolls 3-7 passage processed, afterwards at R3 and the R4 milling train tandem rolling 4 by being disposed close to.The slab rolling of 200-250mm is by roughing district After the intermediate blank of 38-60mm, before being passed to mm finishing mill unit.Intermediate blank becomes 1.2-25.4mm thickness through mm finishing mill unit 5 tandem rolling Finished strip.After strip steel goes out mm finishing mill unit, its temperature is cooled to specify by heat output roller way through section cooling equipment Temperature.Last strip steel is admitted to coiling machine 6 and coils into coil of strip.

Horizontal roller on hot rolling line needs more to renew roller after rolling certain tonnage number.After more renewing roller, need Hydraulic press down system or machinery press down system are carried out Zero calibration, to obtain the information such as Roll-gap position accurately.If simply Change working roll or support roller, owing to the roll gap system change of roll is less, roll gap need not be checked.But if year Repair, periodical repair carried out strip inspection or replacing to machinery pressure and hydraulic press down system, then be accomplished by checking roll gap.

As in figure 2 it is shown, the inspection method of prior art is:

The most first lift roller 7；

Cut off the rolling power supply of roller-way 8 the most again；

Cut off upper roller 7 and the transmission power supply of lower roll 9 the most again；

4. inspection personnel pierces in milling train from outlet, uses tape measure lower roll 9, equal in distance both sides, lower roll 9 center The position setting-out mark of distance；

The most then identify according to setting-out, fill in the copper rod 10 of two same thicknesses from the outlet of milling train；

6. upper roller 7 is pressed downward against, makes roll gap reach the half of copper rod 10 diameter；

The most finally lift roller 7, take out copper rod 10 and measure.

And use existing mode that roll gap is checked, there is following defect:

1. need to pierce milling train from outlet due to inspection personnel, there is potential safety hazard, it is necessary to stop roller-way power supply；

2. the space of some inlet of rolling mills and outlet is less, and inspection personnel cannot pierce, and the method that can only use range estimation will Copper rod is placed in the position of near symmetrical, affects the accuracy of measurement result；

3. copper rod needs to fill in from outlet, in order to avoid security incident, needs longer copper rod, and waste is serious；

The most whole Inspection needs about 30 minutes, time-consuming the most laborious.

Utility model content

For above-mentioned the deficiencies in the prior art, the purpose of this utility model is to provide the inspection of a kind of mill roll-gap Device, it is possible to stretch into mill roll-gap from side, it is to avoid personnel walk on roller-way, by scale location copper rod and the phase of roll To position, improve accuracy and the safety of roll gap Inspection, decrease the activity duration.

For achieving the above object, this utility model adopts the following technical scheme that

The inspection device of a kind of mill roll-gap, including localizer, copper rod, measurement bar and centering claw, localizer has two Individual, two localizers are sheathed on measurement bar respectively, and localizer is respectively equipped with sleeve, and two copper rods pass through sleeve pipe respectively with corresponding Localizer connect, centering claw is also sheathed on measurement bar, and is positioned at the outside of a localizer, measures and is additionally provided with quarter on bar Degree.

Also being equipped with screw on described localizer, localizer is fastened with measuring bar by screw.

Being additionally provided with screw on described centering claw, centering claw is fastened with measuring bar by screw.

Spike the most also it is connected with below described localizer.

In technique scheme, this utility model also has the advantage that

1. check in need not pierce milling train again due to inspection personnel, be not required to cut off roller-way power supply, eliminate safety Hidden danger；

2. the space for some entrance and exits is less and cannot measure the milling train of copper rod putting position, can improve measurement Accuracy；

3. the length of copper rod only needs 300-500mm, very saves material；

The most whole Inspection needs 10 minutes, time saving and energy saving.
