METHOD OF GRAPHITIZATION FURNACE CORE TEMPERATURE DETERMINING

摘要

FIELD: technological processes.;SUBSTANCE: invention relates to graphitized structural materials production, more specifically to graphitization operation. Disclosed new method of graphitization furnace core temperature determining is characterized by fact, that heat insulation layer temperature is measured along normal to core surface in several, but not less than three points simultaneously, wherein in such part of layer, which temperature is not exceeding 1,500 °C. Based on them determining analytical dependence of temperature distribution in temperatures measurement area, and obtained analytical dependence is spread over heat-insulating layer entire thickness. As analytical dependence square trinomial of type is taken t=ax²+bx+c. Coefficients of a, b, c in relationship are determined by simultaneously measured temperatures t(x) in several points x_i in heat insulating layer along normal to core surface. At that, length of normal section perpendicular to core side surface, on which temperature measurements are performed should be not less than 0.2 of heat insulation layer thickness.;EFFECT: simplification of graphitization furnace core temperature determining process, as well as higher accuracy of graphitization furnace core temperature determining.;3 cl
