Abstract

GRUPO REFRIGERADOR PARA EL ENFRIAMIENTO DE MATERIAL LAMINADO CALIENTE (CON O SIN PATENTE DIRECTA) MEDIANTE AGUA A PRESION. EL GRUPO DE REFRIGERACION Y SU PROCEDIMIENTO, OBJETOS DEL INVENTO, SE UTILIZAN PARA EL ENFRIAMIENTO DE MATERIAL LAMINADO DE ACERO O METAL, CONFORMADO, CALIENTE Y QUE PASA A VELOCIDAD DE LAMINACION. LA NOVEDAD PRESENTADA CONSISTE EN REALIZAR LA REFRIGERACION DEL MATERIAL LAMINADO CALIENTE, CUYA EXTRACCION DE CALOR VA ACOMPAÑADA DE MUCHOS IMPONDERABLES CONOCIDOS Y DESCONOCIDOS, EN UN GRUPO REFRIGERADOR QUE CONSTE PREFERENTEMENTE DE TRES CAMARAS DE PRESION, COMO LO MUESTRAN LAS FIGURAS 1,3 Y 10, PARA ASI ELUDIR EFICAZMENTE EL RIESGO IMPLICADO EN EL EXTRACCION DE CALOR, COMO SE OBSERVA EN LAS FIGURAS 5 Y 7. LA OBTENCION DE LA TEMPERATURA DE REFRIGERACION DESEADA, PARTIENDO DE LA TEMPERATURA DE REFRIGERACION REAL ADYACENTE EN CADA CASO, SE PRODUCE A TRAVES DE LA MODIFICACION DE LA CANTIDAD DE AGUA A PRESION QUE FLUYE AL INTERIOR DE LA CAMARA DE PRESION DE CONVECCION (1),CON LO CUAL SE DISMINUYE O SE AUMENTA LA PARTE DE AGUA A PRESION FRENTE A LA PARTE DE VAPOR ( DE LA MEZCLA DE AGUA Y PRESION Y VAPOR) EN LAS CAMARAS DE EVAPORACION A PRESION; CONSIGUIENTEMENTE, SE DISMINUYE O AUMENTA LA EXTRACCION DE CALOR Y, POR LO TANTO, TAMBIEN SE REDUCE O ELEVA LA TEMPERATURA DE REFRIGERACION. CON LA AYUDA DE ESTE GRUPO DE REFRIGERACION Y ESTE PROCEDIMIENTO, RESULTA FACTIBLE AUMENTAR CONSIDERABLEMENTE LA EXTRACCION DE CALOR POR DM3 DE AGUA A PRESION, MEJORANDOSE ASI LA UNIFORMIDAD DEL ENFRIAMIENTO Y REDUCIENDOSE LA CANTIDAD DE AGUA A PRESION QUE HA DE APLICARSE, EN UN 50 A 80% POR TONELADA DE MATERIAL LAMINADO ACABADO, TAL COMO INDICA LA FIGURA 11, CON LA VENTAJA ADICIONAL DE QUE EN EL MATERIAL LAMINADO ACABADO NO SE FORMAN PARTES INTEGRANTES DE LA ESTRUCTURA CON EFECTOS INDESEABLES, DEMOSTRABLES, POR DEPENDENCIA CUALITATIVA DE LA REFRIGERACION.REFRIGERATOR GROUP FOR THE COOLING OF HOT LAMINATED MATERIAL (WITH OR WITHOUT A DIRECT PATENT) THROUGH PRESSURE WATER. THE REFRIGERATION GROUP AND ITS PROCEDURE, OBJECTS OF THE INVENTION, ARE USED FOR THE COOLING OF LAMINATED STEEL OR METAL MATERIAL, CONFORMED, HOT AND RUNNING AT LAMINATION SPEED. THE NOVELTY PRESENTED IS IN THE REFRIGERATION OF THE HOT LAMINATED MATERIAL, WHICH EXTRACTION OF HEAT IS ACCOMPANIED BY MANY IMPONDERABLE KNOWN AND UNKNOWN, IN A REFRIGERATION GROUP OF THREE, THREE CHAMBERS WITH THREE CHAMBERS, PRESENT THREE CHAMBERS AND THREE CHAMBERS, PRESENTING THREE CHAMBERS WITH THREE CHAMBERS AND THREE CHAMBERS, PRESENTING THREE CHAMBERS WITH THREE CHAMBERS AND THREE CHAMBERS, PRESENTING THREE CHAMBERS WITH THREE CHAMBERS AND THREE CHAMBERS WITH THREE CHAMBERS AND THREE CHAMBERS. TO EFFECTIVELY AVOID THE RISK INVOLVED IN THE EXTRACTION OF HEAT, AS OBSERVED IN FIGURES 5 AND 7. OBTAINING THE DESIRED REFRIGERATION TEMPERATURE, BASED ON THE ADJACENT REAL REFRIGERATION TEMPERATURE IN EACH CASE, OCCURS THROUGH MODIFICATION OF THE AMOUNT OF PRESSURE WATER FLOWING INSIDE THE CONVECTION PRESSURE CHAMBER (1), WHICH THE PRESSURE WATER PART IS REDUCED OR INCREASED IN FRONT OF THE VAPOR PART (OF THE MIXTURE OF WATER AND PRESSURE AND VAPOR) IN THE PRESSURE EVAPORATION CHAMBERS; THEREFORE, THE EXTRACTION OF HEAT IS DECREASED OR INCREASED AND THEREFORE, THE REFRIGERATION TEMPERATURE IS ALSO REDUCED OR ELEVATED. WITH THE HELP OF THIS REFRIGERATION GROUP AND THIS PROCEDURE, IT IS POSSIBLE TO INCREASE CONSIDERABLY THE EXTRACTION OF HEAT BY DM3 OF WATER UNDER PRESSURE, SO IMPROVING THE UNIFORMITY OF THE COOLING, WHICH HAS TO BE APPLIED BY 50 80% PER TON OF FINISHED LAMINATED MATERIAL, AS INDICATED IN FIGURE 11, WITH THE ADDITIONAL ADVANTAGE THAT IN THE FINISHED LAMINATED MATERIAL NO INTEGRATING, DEMONSTRABLE EFFECTS OF THE STRUCTURE ARE FORMED BY QUALITATIVE DEPENDENCE.
