Embodiment 1

[0040] This embodiment provides a system for determining the rolling direction of the strip, such as figure 1 As shown, the system includes: a sample fixing device 1, a rotating platform 2, a light source 3, a projection screen 4 and a signal processor 5; wherein,

[0041] The sample fixing device 1 is used to fix the plate and strip samples, the sample fixing device 1 is fixed on the rotating platform 2, and is used to rotate the plate and strip samples; the light source 3 is used to send the plate and strip samples emit light beams; the projection screen 4 is used to receive light reflected by the plate and strip samples to form a reflected image; the signal processor 5 is used to calculate the width of the reflected image, and according to the reflected image in the rotation period The width determines the rolling direction of the strip. Wherein, the plate and strip samples may include: cold-rolled and hot-rolled plates and strips or non-ferrous metal plates and strips. T...

Embodiment 2

[0052] Corresponding to Embodiment 1, this embodiment also provides a method for determining the rolling direction of the strip, such as Figure 5 As shown, the method includes the following steps:

[0053] Step 510, using a sample fixing device to fix the plate and strip sample.

[0054] In this step, the plate and strip samples are fixed on the sample fixing device, and the sample fixing device may include a tray, a bracket, and the like. Wherein, the plate and strip samples may include: cold-rolled and hot-rolled plates and strips or non-ferrous metal plates and strips. The specification of the plate and strip sample is 50mm*50mm, and the thickness is 0.5mm.

Abstract

The invention provides a system and a method for determining the rolling direction of a plate strip. The system comprises a sample fixing device, a rotating platform, a light source, a project screen and a signal processor. The sample fixing device is used for fixing a plate strip sample, and is arranged on the rotating platform. The rotating platform is used for rotating the plate strip sample. The light source is used for emitting beams on the plate strip sample. The project screen is used for receiving light reflected by the plate strip sample to form a reflection image. The signal processor is used for calculating the width of the reflection image, and determining the rolling direction of the plate strip according to the width of the reflection image in the rotating period of the rotating platform. In the rotating period of the rotating platform, when the signal processor determines that the width of the reflection image is the maximum value, the condition that the direction in which the plate strip sample is parallel to the beams is the rolling direction is determined; and when the signal processor determines that the width of the reflection image is the minimum value, the condition that the direction in which the plate strip sample is parallel to the beams is the rolling direction is determined; and therefore, the rolling direction of the plate strip can be determined accurately, so that the accuracy of the detection data detecting result is ensured.

Description

technical field [0001] The invention belongs to the technical field of strip steel rolling direction measurement, and in particular relates to a system and method for determining the rolling direction of a plate and strip. Background technique [0002] Plates and strips have always occupied a very important position in the steel market, and are widely used in bridges, ships, construction, pressure vessels, automobile manufacturing, home appliances and other industries that are closely related to our lives. [0003] With the development of science and technology and industry, people have put forward higher requirements for the properties of plates and strips, including yield strength, tensile strength, elongation, magnetic induction, iron loss (including hysteresis loss, eddy current loss, etc. ), grain size, texture, etc. However, due to the production process characteristics of the plate and strip, there is anisotropy in the internal structure and crystal structure of the ...
