Abstract

Inventia se refera la un valt de laminare tip Pilger, la care, în scopul optimizarii folosirii lui, se propune divizarea zonei de lucru în con de lucru/iesire-calibru de polizare si con de lucru/iesire. în acest sens, calibrarea propusa prezinta urmatoarele carcateristici: a) conul de reducere se desfasoara aproape linear, pe partea superioara, dinspre calibrul de polizare, pe o zona unghiulara de 25 degree , si zona de care se leaga, între 25 si 50 degree , urmareste functia y=d. (a+b.e la puterea c.x la n) b) zona de lucru 0-III a valtului este de 210...235 degree ; c) divizarea zonei de lucru în con de lucru/iesire-calibru de polizare - con de lucru/iesire este în raport de circa 36, 28, 36%.The invention relates to a roller mill type Pilger, in which, in order to optimize its use, it is proposed to divide the working area into a working / output cone-grinding caliber and a work / outlet cone. In this regard, the proposed calibration has the following features: a) the reduction cone is carried out almost linearly, on the upper side, from the grinding caliber, on an angle zone of 25 degrees, and the area to which it is connected, between 25 and 50 degrees, follows the function y = d. (a + b.e at power c.x to n) b) working area 0 to III of the wave is 210 ... 235 degrees; c) dividing the working area into working / output-grinding wheel - the working / outlet cone is in the ratio of about 36, 28, 36%.
