висрмости от изменени температуры обжига, физико-химических свойств материала и его расхода, иамер нэт электропроводность спекаемого материала по статистической св зи с составом материала и температурой обжига определ ют за данную электропроводность, а тепловой поток измен ют в зависимости от скорости изменени рассогласовани между измер емой и згщанной электропроводност ми .viscosity from changes in firing temperature, physicochemical properties of the material and its consumption, and the electrical conductivity of the sintered material is determined by statistical relationship with the composition of the material and firing temperature for this conductivity, and the heat flux varies depending on the rate of change of the error between the measured and electrically conductive.
Способ осуществл ют следующим образом .The method is carried out as follows.
Измер ют величины входных параметров шихты: известн ковый модуль/ 1делочной модуль, количество шихты, подаваемой в печь.The input parameters of the charge are measured: a limestone module / 1 finishing module, the amount of the charge fed to the furnace.
Определ ют по статистической зависимости электропроводности с составом материала и температурой печи заданную электропроводность.The predetermined conductivity is determined by the statistical dependence of the electrical conductivity with the composition of the material and the temperature of the furnace.

Задерживают данные на врем t , необходимое дл продвижени спекаемого материала до участка спекани (дл печи длиной 150 м t i ч 40 мин). Измер ют текущее значение электропроводности материала вначале участка спекани э€|ц. Вычисл ют алгебраическую сумму электропроводности заданной и измеренной. Определ ют скорость изменени рассогласовани заданной и измер емой электропроводностей, Производ т изменение теплового потока в зависимости от величины этой скорости .The data is delayed by the time t required to advance the sintered material to the sintering site (for a furnace with a length of 150 m t i h 40 min). The current value of the electrical conductivity of the material at the beginning of the sintering area e € | c is measured. The algebraic sum of the electrical conductivity given and measured is calculated. The rate of change of the mismatch of the specified and measured electrical conductivities is determined. A change in the heat flux is made depending on the magnitude of this velocity.
