Изобретение СУГНОСИТСЯ к металлургии и может бьггь использовано при спекании РУД.The invention is OVERCESSED to metallurgy and can be used in sintering ores.
Известен способ И определени места законченности процесса спекани в зависимости от интенсивности теплового излучени зоны спекани , контролируемой в диапазоне длин волн 1,6-2,1 мк.The known method AND determining the place of completion of the sintering process, depending on the intensity of thermal radiation of the sintering zone, controlled in the wavelength range of 1.6-2.1 microns.
Недостатки способа - сложность оборудовани и большие эксплуатационные затраты.The disadvantages of the method is the complexity of the equipment and high operating costs.
Наиболее близким к предлагаемому вл етс способ, согласно которому место законченности контролируют по величине усадки 21 .Closest to the present invention is a method according to which the place of completion is controlled by the amount of shrinkage 21.
Недостатком известного способа вл етс неоднозначность св зи межу величиной усадки и координатой места.The disadvantage of this method is the ambiguity of the connection between the amount of shrinkage and the coordinate of the site.
Цель изобретени - повышение точности .The purpose of the invention is to improve accuracy.
Поставлеш1 1 цель достигаетс определением места законченности спекани при непрерывно измер емой высоте агло-Deliver 1 The goal is achieved by determining the place of completeness of sintering at continuously measured agglomeral height.
спека в щх хессе сп ;ани по прекрашекию изменени высоты агпоспека.speke in shch Hesse sp; ani by stopping the change in the height of the agspace.
Известно, что в установнЕШЯЙс период спекани измен га структуры сло происход т в зоне формщювани агломерата при разм гчении и плавлении шихты. По вление жидкой фазы сопровождаетс ее ст гиванием в результате действи молекул рных сил к отдельным контактным участкам, что приводит к усадке, It is known that in the established sintering period, changes in the structure of the layer occur in the zone of sintering of the agglomerate during softening and melting of the charge. The appearance of the liquid phase is accompanied by its contraction due to the action of molecular forces on individual contact areas, which leads to shrinkage,
10 котора обусловлена температурно-тепловым уровнем процесса спекани .10 which is caused by the temperature-thermal level of the sintering process.
По длине агломашины устанавливаютс , например, п ть датчиков высоты сло : первый контролирует высоту сло за за15 грузочным лотком, а остальные четыре над последними вакуумкамерами.For example, five sensors for the height of the layer are installed along the length of the sintering machine: the first controls the height of the layer behind the loading tray and the remaining four above the last vacuum gauges.
Датчики высоты непрерывно измер ют высоту аглоспека, показани которых поступают в устройство сравнени и вычио The height sensors continuously measure the height of the aglospeck, the readings of which are fed into the comparison device and
20 лени дл определени разности между показани ми соседних датчиков.20 for determining the difference between the readings of adjacent sensors.
Достижение разности, показаний соседних датчиков нулю означает; прекращениеAchievement of the difference, readings of neighboring sensors means zero; termination

Реализаци лрещюгаемого стособа позвсхп ет с пбвЫшенной точностью определить Место законченности прсщесса спеканва, 4to обеспечивает получение качествад ного агломерата и увеличение пронзвоштельности машин.The implementation of the interchangeable center allows you to determine the place of completeness of the special process, with 4 accuracy, which ensures quality agglomerate and an increase in the productivity of the machine.
