Abstract
The method that built-up welding supporting roller diameter is measured under a kind of Warm status of the present invention, equipment is opened without interrupt operation, rod face girth is less manually measured at high temperature, calculated using simple geometry, overall operating efficiency can be improved, while it also avoid staff's exposure at high operating temperatures to draw the rod face diameter under working condition, it is safer, quickly.
Description
Technical field：
The present invention relates to a kind of method of built-up welding backing roll in-site measurement built-up welding diameter, the especially built-up welding just in stay-warm case
The condition of high temperature under measurement built-up welding supporting roller diameter method.
Background technology：
Backing roll is one of important component of metallurgy rolling mill, and because its applying working condition is severe, roll surface is easily impaired, breakaway,
Need Bead weld repair.Its bead-welding technology is usually to use automatical hidden arc overlay welding, Bead weld repair is carried out in stay-warm case, its built-up welding
Journey and heat treatment process are completed in stay-warm case entirely.Surfacing equipment system mainly includes：Work rotate and support system, welding machine and
The insulation cover system etc. of flux delivery system, temperature control/thermometric, this set system substantially closes backing roll, only on device systems
Open window is left in portion and side.Whole weld deposit process, backing roll are nearly among the closing of device systems, roll surface temperature
Up to 300 DEG C~400 DEG C, weld deposit process centre measuring roller diameter is extremely difficult thing.Traditional measurement method is to set
Standby system is opened, it is hot it is lower measure roll surface girth with steel tape, be then convert into diameter, operating difficulties, error is big.
The content of the invention：
In order to solve the above problems, the invention provides a kind of method that built-up welding supporting roller diameter is measured under Warm status.
The technical solution adopted for the present invention to solve the technical problems：
A kind of method that built-up welding supporting roller diameter is measured under Warm status, is comprised the following steps：
1) No.1 round steel wire is drawn along backing roll length direction, it is levelling with Laser Line Marker, ensure No.1 round steel wire and branch
Runner diameter parallel；
2) weight is fastened No. two round steel wire lower ends, under gravity, is slided along roller shaft head periphery, final No. two
Round steel wire is vertical with roller axis, while vertical with No.1 steel wire, measure and record roller shaft head radius r and No.1 round steel wire with
The distance L that No. two round steel wires project in horizontal plane1；
3) No. two round steel wires in step 2) are removed after hanging up weight, the upper operating window of slave unit system workbench
Mouthful, No. two round steel wires are slided along built-up welding roll surface, under gravity, No. two round steel wires slide close to roll surface, finally and roller
Sub- axis is vertical, while vertical with No.1 round steel wire, now, measures and records No. two round steel wires with No.1 round steel wire in horizontal plane
The distance L of projection2；
4) because No.1 round steel wire and roller axis in the distance that horizontal plane projects are certain value, steel wire diameter is relative to heap
Welding roller diameter can be neglected, then r+L1=Φ/2+L2, therefore roller diameter Φ=2 × (r+L of built-up welding1-L2)。
Described No.1 steel wire rope can not be in same level with supporting roll axis.
Due to using technical scheme as described above, the present invention has following superiority：
The method that built-up welding supporting roller diameter is measured under a kind of Warm status of the present invention, opens without interrupt operation and sets
It is standby, roll surface girth is less manually measured at high temperature, is calculated using simple geometry, can be to draw the roller under working condition
Face diameter, overall operating efficiency is improved, while it also avoid staff's exposure at high operating temperatures, it is safer, soon
Speed.
Brief description of the drawings：
The front view of Fig. 1 surfacing equipments of the present invention；
Fig. 2 is the left view of surfacing equipment of the present invention；
Fig. 3 is the partial enlarged drawing that Fig. 2 omits surfacing equipment；
Embodiment：
The present invention can be explained in more detail by the following examples, the open purpose of the present invention is intended to the protection present invention
In the range of all changes and improvements, the invention is not limited in the following examples；
The method that built-up welding supporting roller diameter is measured under a kind of Warm status with reference to described in accompanying drawing, is comprised the following steps：
1) draw No.1 round steel wire 1 along backing roll length direction, it is levelling with Laser Line Marker, ensure 1, No.1 round steel with
Backing roll diameter parallel；
2) weight is fastened No. two lower ends of round steel wire 2, under gravity, is slided along the periphery of roller shaft head 4, final two
Number round steel wire 2 and supporting roll axis are vertical while vertical with No.1 round steel wire 1, measure and record the radius r=of roller shaft head 4
317mm, and the distance L that No.1 round steel wire 1 and No. two round steel wires 2 project in horizontal plane1=1403mm；
3) No. two round steel wires 2 in step 2) are removed after hanging up weight, the upper operating of slave unit system workbench
Window, No. two round steel wires 2 are slided along the face of Technology of Welded Roller 3, under gravity, No. two round steel wires 2 slide close to roll surface, finally
It is vertical with roller axis while vertical with No.1 round steel wire 1, now, measure and record No. two round steel wires 2 and No.1 round steel wire 1
In the distance L of horizontal plane projection2=622mm；
4) because No.1 round steel wire 1 and roller axis in the distance that horizontal plane projects are certain value, steel wire diameter relative to
Built-up welding roller diameter can be neglected, then r+L1=Φ/2+L2, therefore diameter of phi=2 of Technology of Welded Roller 3 × (r+L1-L2)=2 ×
(317+1403-622)=2196mm.
Described No.1 steel wire rope 1 can not be in same level with supporting roll axis.
It is prior art not state part in above content carefully, therefore does not run business into particular one and state.
Claims (2)
