Abstract

EL INVENTO ES UN PROCEDIMIENTO Y UN HORNO PARA UN PROCESO DE CALENTAMIENTO EFICAZ, EN EL CUAL LA MATERIA A CALENTAR SE TRANSPORTA POR UN SISTEMA DE RODILLOS DE EMPARRILLADO ELEVADORES DISCONTINUO EN EL HORNO. EL RODILLO DE TRANSPORTE (15) SE DISPONE EXTERIORMENTE A LAS PAREDES LATERALES (11) DEL HORNO, TRANSVERSAL A LA DIRECCION DEL TRANSPORTE DEL MATERIAL A CALENTAR Y TIENE MMOVIMIENTO DE VAIVEN Y SOLAMENTE SE MUEVE EN EL INTERIOR (10) DEL HORNO BAJO LAS PIEZAS A CALENTAR (13) DURANTE UN BREVE INTERVALO DE TRANSPORTE DE MATERIAL Y MEDIANTE ORIFICIO DE PESO (18). EL LAVANTAMIENTO DE LOS RODILLOS DE TRANSPORTE (15) O EN LA BAJADA DE LOS BLOQUES DE RESERVA (14) EL RODILLO DE TRANSPORTE (15) RECIBE EL MATERIAL A CALENTAR Y LO TRANSPORTA PASO A PASO MEDIANTE BREVES MOVIMIENTOS GIRATORIOS. EL RODILLO (15) DE TRANSPORTE DESMONTA LA PIEZA DE MATERIAL A CALENTAR A TRAVES DE UN MOVIMIENTO RELATIVO, PERPENDICULAR Y ALTERNATIVO DEL BLOQUE (14) DE RESERVA Y DICHO RODILLO (15) DE TRANSPORTE SE LLEVA A UNA POSICION DE REPOSO REFRIGERADA. ESTA DISPOSICION DEL RODILLO DE TRANSPORTE POR FUERA DEL HORNO ACCIONA CARGAS PEQUEÑAS CON PEQUEÑO DESGASTE PORQUE SOLAMENTE SE PRODUCE UNA FASE DE REFRIGERACION ELEVADA EN EL HORNO CALIENTE (10) DURANTE BREVES PARADAS. TAMBIEN LA INSTALACION DE REFRIGERACION DE AGUA PARA LA VIA DE RODILLOS DE TRANSPORTE SE ECONOMIZA EN EL INTERIOR DEL HORNO.THE INVENTION IS A PROCEDURE AND AN OVEN FOR AN EFFECTIVE HEATING PROCESS, IN WHICH THE MATTER TO BE HEATED IS TRANSPORTED BY A DISCONTINUOUS LIFTING ROLLER SYSTEM IN THE OVEN. THE TRANSPORTATION ROLLER (15) IS DISPOSED EXTERNALLY TO THE SIDE WALLS (11) OF THE OVEN, TRANSVERSAL TO THE DIRECTION OF THE TRANSPORTATION OF THE MATERIAL TO BE HEATED AND HAS MOVING MOVEMENT AND IS ONLY MOVED INSIDE (10) OF THE OVEN UNDER THE PIECES TO HEAT (13) DURING A SHORT INTERVAL OF MATERIAL TRANSPORT AND THROUGH A WEIGHT HOLE (18). THE WASHING OF THE TRANSPORT ROLLERS (15) OR IN THE DESCENT OF THE RESERVE BLOCKS (14) THE TRANSPORT ROLLER (15) RECEIVES THE MATERIAL TO BE HEATED AND TRANSPORTS IT STEP BY STEP BY BRIEF SWIVELING MOVEMENTS. THE TRANSPORT ROLLER (15) REMOVES THE PIECE OF MATERIAL TO BE HEATED THROUGH A RELATIVE, PERPENDICULAR AND ALTERNATIVE MOVEMENT OF THE RESERVE BLOCK (14) AND SUCH TRANSPORT ROLL (15) IS TAKEN TO A REFRIGERATED REST POSITION. THIS DISPOSAL OF THE OUT-OF-OVEN TRANSPORTATION ROLL DRIVES SMALL LOADS WITH LITTLE WEAR BECAUSE ONLY A HIGH COOLING PHASE OCCURS IN THE HOT OVEN (10) DURING SHORT STOPS. ALSO THE INSTALLATION OF WATER COOLING FOR THE ROAD OF TRANSPORTATION ROLLERS IS ECONOMIZED IN THE INTERIOR OF THE OVEN.
