Measuring device and method for roller seams and inclined planes of tension sizing reducing mill

Abstract

The invention relates to the technical field of tension sizing reducing mills, in particular to a measuring device and a measuring method for roller seams and inclined planes of a tension sizing reducing mill. The measuring device comprises a measuring frame, wherein the two ends of the measuring frame are respectively provided with measuring parts; the two measuring parts are arranged in an inclined mode towards the outer side of the measuring frame; the two measuring parts are positioned above or below the measuring frame; measuring inclined planes are arranged on the measuring parts; the measuring inclined planes on the two measuring parts are symmetrically arranged with respect to a perpendicular line in the middle of the measuring frame; a dial indicator is arranged on one measuring part; a measuring rod of the dial indicator and the measuring inclined planes are perpendicularly arranged; and the measuring rod of the dial indicator extends out of the measuring inclined planes. The measuring device can quickly and effectively carry out high-precision high-efficiency measurement on size of an opposite-milling roller conical surface, roller seams among milling rollers and milling roller inclined planes, so that the product problem caused by inaccurate measurement is avoided.

Description

technical field [0001] The invention relates to the technical field of tension reducing machines, in particular to a device and method for measuring roller gap slopes of tension reducing machines. Background technique [0002] Tension setting and reducing machine roll is one of the main rolling tools in the production of hot-rolled seamless steel pipes. It enables the waste pipe to be reduced and sized in a state of slight tension, so as to obtain finished steel pipes of various specifications. Currently, most of them are used. It is a three-roll rolling reduction machine, that is, three rolls are set on the frame, and the rolling channel of the steel pipe is enclosed between the three rolls. The quality of the steel pipe plays a key role. When the roll gap between adjacent rolls is large, the surface finish of the rolled steel pipe cannot meet the requirements, and there will be defects such as spiral patterns and the inability to realize steel pipe rolling reduction and si...

[0002] Tension setting and reducing machine roll is one of the main rolling tools in the production of hot-rolled seamless steel pipes. It enables the waste pipe to be reduced and sized in a state of slight tension, so as to obtain finished steel pipes of various specifications. Currently, most of them are used. It is a three-roll rolling reduction machine, that is, three rolls are set on the frame, and the rolling channel of the steel pipe is enclosed between the three rolls. The quality of the steel pipe plays a key role. When the roll gap between adjacent rolls is large, the surface finish of the rolled steel pipe cannot meet the requirements, and there will be defects such as spiral patterns and the inability to realize steel pipe rolling reduction and sizing. If the roll gap is too small, the three rolls are likely to be stuck and unable to rotate, and rolling accidents are prone to occur, causing damage to the steel pipe, as well as damage to the rolls and their equipment
