A segmented contact type hot rolling roll shape detection device

Abstract

The invention discloses a segmented contact type hot-rolled roll plate shape detection device. The device comprises a main roll body, a water inlet and outlet device, a detection device body and a data processing control center. The main roll body comprises an outer roll body and an inner roll body, wherein the outer roll body is in a segmented type and composed of two outer roll end covers, two outer roll cushion blocks and multiple segmented outer roll bodies, the inner roll body is in an integrated type, the outer roll body rotates under the effect of the static frictional force of a plate, and the inner roll body is fixed; the water inlet and outlet device is used for introducing cooling liquid for cooling; by means of the detection device body, the interval between two polar plates is changed by sensing the change of the surface thickness of the plate by measuring steel balls, and a capacitance value is fed back to a processing center; and by means of the data processing control center, the thickness of the plate is worked out, and the closing and the flow of a water inlet valve are controlled. The segmented contact type hot-rolled roll plate shape detection device is simple in structure and easy to mount and dismount, the design is novel, the plate shape of the high-temperature rolled plate is measured, and the segmented contact type hot-rolled roll plate shape detection device is of important practical significance.

Description

technical field [0001] The invention belongs to the technical field of rolling measurement, and relates to a segmental contact type hot rolling roll shape detection device, which is used for the shape measurement of rolled plates. Background technique [0002] Strip steel is one of the main products of the steel manufacturing industry, and it is widely used in automobiles, ships, aviation, machinery and other fields. Plate shape is one of the important indicators to measure the quality of cold and hot-rolled plates, and the poor flatness of the plate and strip will affect a series of subsequent process operations. And with the continuous development of modern industrial technology, the thickness of hot-rolled strips is getting thinner and thinner, which can gradually replace cold-rolled steel products in more fields, so it is very important to study the shape of hot-rolled strips. However, the working temperature of the hot-rolled strip is high, the environment is harsh, th...

Problems solved by technology

The non-contact type is mainly used for indirect detection of plates, mainly used for the measurement of cold-rolled steel strips, and the measurement accuracy is low; the contact type mainly uses detection rollers to measure the tensile stress of each point of the plate to detect potential problems in the plate shape, so it has a direct detection signal. , high measurement accuracy and other characteristics, mainly include the stress type shape meter developed by Northeastern University and the segmented roller shape meter developed by ABB Sweden, but this type of measuring device is greatly affected by high temperature, vibration, floating, etc.
