Description

Предлагаемый способ исследовани  перемещений деформируемого металла относительно поверхности обрабатываемого инструмента - валков, бойков и т. п. основан на магнитных свойствах материалов.The proposed method for studying the displacements of a deformable metal relative to the surface of the tool being machined — rolls, strikers, etc., is based on the magnetic properties of the materials.

Сущность способа состоит в том, что в прокатный валок / (см. черт.) вмонтирован индуктивный датчик 2, корпус 3 которого изготовлен из парамагнитного материала. Магнитопроводы 4 датчика выполнен) из электротехнической стали, выведены па пове; хность валка и здесь разорваны. Магнитное поле, создаваемое обмотками 5, замыкаетс  в основном пластинкой (ферроточкой) 6 размерами 1X1,5X0,3 из ферромагнитпого материала. Перед каждым рабочим пропуском пластинка (ферроточка) 6 крепитс  к поверхности валка (бойка) клеем. Обмотки датчика включены в дифференциальный .мост ипдуктивностей, который питаетс  током звуковой частоты (в данном случае - 800 гц). В измерительную диагональ моста через электронный усилитель включаетс  щлейф осциллографа. Электрическа  св зь датчика с аппаратурой осу1цествл етс  через коллектор и токосъемник.The essence of the method lies in the fact that the mill roll / (see. Fig.) Mounted inductive sensor 2, the body 3 of which is made of a paramagnetic material. The magnetic cores of the 4 sensors are made of electrical steel; The knackiness of the roll is also broken here. The magnetic field created by the windings 5 is closed mainly by a plate (ferrite) 6 with dimensions 1X1.5X0.3 made of ferromagnetic material. Before each working pass, the plate (ferropoint) 6 is attached to the surface of the roll (striker) with glue. Sensor windings are included in the differential bridge and inductances, which are powered by an audio frequency current (in this case, 800 Hz). An oscilloscope loop is inserted into the measuring diagonal of the bridge through an electronic amplifier. The electrical connection of the sensor to the equipment is through a collector and a current collector.

При прокатке в момент входа в очаг деформации пластинка (ферроточка ) стаповитс  придатком поверхности прокатываемой полосы и, следовательно , перемещаетс  относительно поверхности валков вместе с полосой . При перемещении пластинки (ферроточки) относительно полюсов баланс моста нарущаетс  и ток небаланса записываетс  на движущуюс  пленку. В этом случае получаетс  непрерывна  крива , отображающа  характер перемещени  поверхности прокатываемого образца относительно поверхности валка.When rolled at the time of entry into the deformation zone, the plate (ferro point) stacks with the appendage of the surface of the rolled strip and, consequently, moves relative to the surface of the rolls together with the strip. When the plate (ferro-points) is moved relative to the poles, the balance of the bridge is disturbed and the unbalance current is recorded on the moving film. In this case, a continuous curve is obtained, reflecting the nature of the movement of the surface of the rolled sample relative to the surface of the roll.
