Method and apparatus for slitting steel slabs

A cutting table assembly for oxy cutting comprising a cutting table having a slab loading face and mounted for pivotal movement between a loading position in which the loading face is generally horizontal and a cutting position in which the face is oblique, and a pair of torches mounted on the table. The loading face is constituted by a pair of loading subfaces separated by a slot and the torches are mounted in the slot below the loading face. The torches are positioned at opposite ends of the slot prior to the initiation of the cutting action and, upon the initiation of the cutting action, move toward each other and cut into opposite ends of the slab. A pair of gantries are mounted on the table and each carries a deburring device positioned in overlying opposition to a respective torch. Each gantry further includes a plurality of spaced downwardly directed nozzles which are supplied with compressed air to generate an air curtain.

Method and device for the robot-controlled cutting of workpieces to be assembled by means of laser radiation

In a method for robot-controlled cutting of workpieces to be joined by laser radiation, a first workpiece is arranged in vicinity of a second workpiece in a first position. A laser is focused onto the first workpiece. A contour of the first workpiece is cut with the laser beam; this contour is to be assembled and joined with the second workpiece. During cutting, a first spacing of a focal point of the laser beam from the second workpiece is repeatedly determined in a distance direction that is identically oriented during cutting and is adjusted to a direction of assembling the first and second workpieces. During cutting, a second spacing of a processing point of the laser beam from the second workpiece is maintained at a constant value.

Accelerated steel cutting methods and machines for implementing such methods

A method for cutting steel includes heating a portion of the steel until it is molten, positioning a cutting torch to have a high angle of incidence relative to the molten steel, and blasting hgih pressure oxygen at the molten metal. The blast of high pressure oxygen further heats the molten metal and blows the molten metal away from the steel to create a cutting trench. The cutting torch is then moved generally parallel to the cutting method includes a cutting torch that emits a high pressure combustible gas and a high pressure combustion enhancing gas. The torch directs the high pressure gases at the steel so that the gases hit the steel at an acute angle of attack. An automated device propels the torch in the general direction of the desired cut. The resultant cut metal product has at least one edge with a grain pattern that is not perpendicular to the direction of cut.
