INSTALLATION FOR CONTINUOUS CASTING billets, blooms and slabs WITH INSTALLATION AND TRIMMING CUTTING PREPARED IN THE SAME PLACE OR LATER, BY PRODUCT FLOW FOR PRODUCTION safely, quickly and with low maintenance, elaborate SHORTER AND PARTS BURR FREE. a) Continuous casting plant for billets, blooms, slabs and sheets with a cutting and deburring arranged on the spot or later as the product flow for safely, quickly and with reduced maintenance elaborate pieces production ( 2) shorter and deburred, characterized by the provision of one or more flame cutting machines (1) between pistasde displacement (3) water-cooled, upper and lower arrangement which can be displaced also laterally by chains thrust or traction devices or rack and pinion, based on a frame (4) of the machine in the form of L, [either% or, with guide wheels and upper and lower displacement (5) being arranged in said frame a vertical and perpendicular to the cast strand (2) displaceable carriage (14) which - is movable by the bar (2) through lateral attachment device (7) or fixing, superio r (10) - is adjustable in height by motor means, hydraulic or pneumatic, - comprising a bearing pad (10) surrounding the guide bottom scroll (3) or carrying - a pair of levers lateral fixing (7) driven synchronously by a cylinder (8) operating perpendicularly, - and one or two cutting devices (15) with burners cutting (9) displaceable swingably or parallel, for vertical or horizontal cutting, tilting in height or removable upward for changing nozzles, - and an apparatus (31) for deburring operated technical gases, to the output side of the cutting beam exactly at the lower edge of the workpiece and apart cutting burners (9), its ylosbrazos supports (11) delos oeventualmente burners edge detectors, any other part itself of the flame cutting machine (1) projects below the track displacement water cooled. (3). Before the machine frame or it is provided a supply system and regulation of gas and oxygen to each burner and each medium used, with an electromagnetic valve membrane (65) with pressure detectors, and solenoid valves for adjustment and regulation to change, after a heating flame onset of intense cutting, a cutting flame working weaker, in order to avoid or reduce the formation of beads residue or prevent buildups on the upper edge of cut. Below or after the working area of ​​the flame cutting machine (1) is an apparatus for mechanical buffing (32) provided with a cursor in an arc, which is formed by a roller with a removable Decorte cap (36) which also acts as support and transport of workpieces (2) short in length or can be pivoted or the arranged directly alongside one another in package form with ends device work (2) arcuate upwards are provided or down before deburring said end, so that all affected undersides of cutting burrs at the ends are disposed at the same height. In several deburring workpieces (2) on its own roller tables individual deburring device (53-62) for each continuous casting line is available, that for the linear displacement of the plunger deburring (35) is provided car deburring (53) supporting blades deburring (36) with a drive device comprising an electric motor (58), a spindle nut (61) and spindle (60) and is moved by sliding bushes ( 55) on sliding rods (50).
