Abstract

SE DESCRIBE UN PROCEDIMIENTO BAJO APLICACION DE UN GRUPO DE REFRIGERACION PARA LA REFRIGERACION DIRIGIDA DEL MATERIAL DE PRODUCTOS FORMADOR, DE PESADOS A LIGEROS, CALIENTES DLUIDOS DE ACERO Y METAL EN AGUA DE PRESION, DONDE SE HACE USO DE UNA CAMARA DE PRESION UNICA O VARIAS, CUYO VOLUMEN ES PRECALCULABLE DEPENDIENTE DE LA PRODUCCION. EL VOLUMEN ESTA LIMITADO HABITUALMENTE A TRAVES DE DOS DIAFRAGMAS DE ESTRANGULACION O SEA, ESTOS ESTRECHAMIENTOS FORMADOS. SE PREVEE AL MENOS UNA AFLUENCIA DEL AGUA DE PRESION, DE CONDENSACION Y / O DE REFRIGERACION, DE CONDUCCION PARA CADA CAMARA DE PRESION. EL MATERIAL PARA REFRIGERAR SE IMPULSA CON UNA CANTIDAD DE AGUA DE PRESION, QUE SEA NECESARIO, PARA RETIRAR EL CALOR DEL MATERIAL DE PRODUCCION, DONDE EL AGUA DE PRESION DE REFRIGERACION, QUE FLUYE EN EL GRUPO REFRIGERADOR A PRESION Y EN LA PIEZA REFRIGERADORA DE CONVECCION SE CALIENTA JUNTO CON EL AGUA DE PRESION DE LA CONDUCCION, QUE FLUYE AL LADO, PREFERENTEMENTE HASTA EL PUNTO DE EBULLICION. LA MEZCLADE VAPOR Y DE AGUA CALIENTE PRODUCIDA DE TAL SE RETIRA EN LA PIEZA REFRIGERADORA DE EVAPORACION DIRECTAMENTE A CONTINUACION A TRAVES DEL CALOR DE LA EVAPORACION NECESARIO DE LA MEZCLA DE AGUA CALIENTE Y DE VAPOR, AL MATERIAL DE LA PRODUCCION CALOR A CONTINUACION. SE DIMENSIONA LA LINEA DE ALIMENTACION TAL MANERA PARA EL GRUPO REFRIGERANTE DE PRESION, QUE LAS PERDIDAS DE PRESION SON ESCASA EN SI MISMO, POR LO CUAL HAY DISPUESTAS EN LAS LINEAS DE ALIMENTACION VALVULAS REGULADORAS DE CIRCULACION CON ARTICULACIONES DE MANDO.A PROCEDURE IS DESCRIBED UNDER THE APPLICATION OF A REFRIGERATION GROUP FOR THE DIRECT REFRIGERATION OF FORMING PRODUCTS MATERIAL, FROM HEAVY TO LIGHTWEIGHT, HOT DUTY STEEL AND METAL IN PRESSURE WATER, WHERE USE IS MADE OF A SINGLE OR OTHER PRESSURE CHAMBER. WHOSE VOLUME IS PRE-CALCULABLE DEPENDING ON PRODUCTION. VOLUME IS HABITUALLY LIMITED THROUGH TWO DIAPHRAGMS OF STRANGULATION OR WHETHER THESE NARROWS ARE FORMED. AT LEAST AN INFLUENCE OF PRESSURE WATER, CONDENSATION AND / OR COOLING, CONDUCTION IS PROVIDED FOR EACH PRESSURE CHAMBER. THE REFRIGERATING MATERIAL IS DRIVEN WITH AN AMOUNT OF PRESSURE WATER, WHICH IS NECESSARY, TO REMOVE THE HEAT OF THE PRODUCTION MATERIAL, WHERE THE REFRIGERATION PRESSURE WATER FLOWS IN THE PRESSURE REFRIGERATOR GROUP AND IN THE REFRIGERATOR PART IT IS HEATED TOGETHER WITH THE PRESSURE WATER FROM THE CONDUCTION, WHICH FLOWS TO THE SIDE, PREFERABLY TO THE BOILING POINT. THE MIXTURE OF STEAM AND HOT WATER PRODUCED FROM SUCH IS REMOVED IN THE EVAPORATION REFRIGERATOR PART DIRECTLY FOLLOWING THROUGH THE HEAT OF THE EVAPORATION NECESSARY OF THE MIXTURE OF HOT WATER AND STEAM, TO THE MATERIAL OF HOT PRODUCTION. THE FEEDING LINE IS DIMENSED SUCH A WAY FOR THE PRESSURE REFRIGERATING GROUP, THAT THE LOSSES OF PRESSURE ARE LITTLE IN ITSELF, THEREFORE, THERE ARE PROVISIONS IN THE FEEDING LINES FOR CONTROLLED CIRCULATION VALVES WITH CONTROL JOINTS.
