The amount of elongation of a workpiece during forging can be determined by image processing to calculate the total amount of horizontal movement of marked patterns such as forging scale on the ends of the workpiece which move away from a forging bite during the forging blow. Images of marked patterns before and after a forging blow on both sides of the bite of a forging die are compared to determine the movement of the marked patterns and thus the movement of the ends of the workpiece. A method and system of determining the elongation and vertical displacement of a workpiece during forging is disclosed.

The present invention relates to a method for repairing a protective lining of an industrial reaction or transport vessel, such as a converter vessel, electric arc furnace, or ladle. The method comprises identifying combined areas of the lining having a thickness below a predetermined threshold value by means of a measuring device, which measuring device measures the residual thickness of the lining and a processing unit, which processing unit in a first step transforms the residual thickness data into binary data, by comparing the measured residual thickness data with the predetermined threshold value for the thickness of the lining, and assigning the binary value '1' to areas of the lining having a thickness below the pre-determined threshold value, and the binary value '0' to areas of the lining having a thickness equal or higher than the pre-determined threshold value, or vice versa, in a second step combines isolated areas of the lining having a thickness below the predetermined threshold value into combined areas of the lining to which the binary value for areas of the lining having a thickness below the pre-determined threshold value is assigned, and in a third step computes the position and repair sequence of each of the combined areas and transfers these data to a repair device, and applying monolithic lining material onto the combined areas computed by the processing unit by means of a repair device.

A method of a method for measuring wear in the lining of a metallurgical melting vessel such as a steel converter (), by a laser scanner () A laser having a contouring system on a cart can be moved between measurements The laser contouring system references three permanent marks behind the cart (PM, PM, PM) and two temporary marks positioned near the vessel (TM, TM) The distances from the movable cart to each of the five marks is determined during an initial measurement by the contouring system Every time the cart is moved and a new measurement is taken, the contouring system scans the vessel and the two temporary marks but not the permanent marks.

A method and apparatus for optimizing the forging of a workpiece that is moved along a longitudinal axis of a forging press. The method includes detecting the relative positions of the first and second ends of the workpiece along the longitudinal axis and calculating a length of the workpiece therebetween.

An optical beam separation element for a measuring apparatus includes a reflecting component with a reflecting surface and an aperture for forming an optical channel common to the transmission and the reception directions in the optical beam separation element. The reflecting surface of the reflecting component is positioned at an angle with respect to the optical channel. The aperture extends from the reflecting surface through the optical beam separation element allowing the optical beam to pass through the optical beam separation element to the optical channel in the transmission direction. The reflecting component separates the optical beams of the reception and the transmission directions.

According to the invention, a method for identifying and determining die position of a metallurgical vessel for measuring its fireproof lining using electromagnetic radiation, an operator is defined in relation to a two or three dimensional structure with a known shape and size. Distance values and corresponding measuring angles are determined in the area of the structure and measured distance value and corresponding measuring angles are used to scale the operator. The dimension and resolution of the operator in the pixel coordinates system and the anticipated values of the operator are adapted to the measured polar coordinates. A result value is then formed from the differences between the anticipated values of the operator and the measured values and the location of the structure that is sought is determined from the position of the minimum result value.
