Abstract: Изобретение относится к области металлургии. Способ непрерывного литья заготовок включает подачу металла в неразъемный кристаллизатор, вплотную состыкованный с разъемным, формирование заготовки с жидкой сердцевиной в неразъемном кристаллизаторе, формирование разделяющими выступами разъемного кристаллизатора нескольких заготовок с перемычками и разделение этих заготовок после разъемного кристаллизатора. В неразъемном кристаллизаторе, боковые стенки которого выполняют в виде полукруга с радиусом, равным половине толщины полости кристаллизатора, формируют заготовку с круглыми боковыми поверхностями, содержащую оболочку и жидкую фазу, толщина которой составляет 10-15% от толщины заготовки. Формирование заготовок в разъемном кристаллизаторе осуществляют в два этапа: разделяющими выступами стенок-бойков в направлении, перпендикулярном оси движения заготовки, осуществляют смыкание стенок оболочки и исключение жидкой фазы с образованием перемычек, а затем одновременно обжимают каждую заготовку по двум взаимоперпендикулярным направлениям с исключением из них жидкой фазы. Обеспечивается повышение стабильности процесса литья нескольких заготовок, что приводит к улучшению их качества. 2 н.п. ф-лы, 5 ил. 1 пр.

Abstract: FIELD: loading systems.SUBSTANCE: invention relates to the loading of material into train cars. A train loading system for loading material into train cars contains a reclaimer, an intermediate hopper, direct and inverse connection components. The reclaimer is made with the possibility of taking from a stack with some consumption of material for loading into the train. The hopper is made with the possibility of receiving material from the reclaimer and feeding it to cars that move under the hopper. The hopper contains a gate with an adjustable opening position to change the flow rate of the output material flow and the flow rate when loading into the train. The opening position of the gate depends on the train speed. An increase in the train speed entails a position of the gate, at which the opening and the flow rate when loading the train are increased. When the speed is decreased, the opening and the flow rate when loading the train are decreased. The direct connection component is made with the possibility of determining the train speed taking into account the direct connection based on the flow rate during the intake. The train speed, taking into account the direct connection, is used to set the train speed. The inverse connection component is made with the possibility of changing the train speed taking into account the direct connection based on the amount of material in the intermediate hopper. The method for loading material into train cars includes intaking for loading from the stack of material, receiving from the reclaimer into the hopper and feeding material from the hopper into cars, determining the train speed taking into account the direct connection based on the flow rate during the intake, changing the train speed taking into account the direct connection based on the amount of material in the hopper.EFFECT: maintenance the amount of material in the intermediate hopper at a level that avoids stopping the reclaimer or stopping the train due to the level of material in the intermediate hopper is achieved.46 cl, 1 tbl, 6 dwg
