Изобретение относитс  к способу термической обработки прутка с использованием псевдоожиженного сло .This invention relates to a method of heat treating a rod using a fluidized bed.

Известен способ термической обработки прутка в псевдоожиженном слое твердых частиц, где прочность прутка может измен тьс  путем изменени  скорости охлаждени  прутка, проход щего через псевдоожиженный слой.A known method of heat treatment of a rod in a fluidized bed of solid particles, where the strength of the rod can be varied by changing the cooling rate of the rod passing through the fluidized bed.

Согласно известному способу термичес кой обработки температура псевдоожиженного сло  измен етс  дл  изменени  скорости охлаждени  прутка.According to a known heat treatment method, the temperature of the fluidized bed is changed to change the cooling rate of the rod.

Недостатком такого способа термической обработки прутка  вл етс  необходимость облицовывать внутренние поверхности бака, выполненного из стальных пластин , жаропрочным кирпичом в том случае, когда температура псевдоожиженного сло  увеличиваетс  до 600°С. Кроме того, твердые частицы- вылетают с поверхности псевдоожиженного сло  во все стороны, что приводит к необходимости использоват пылесборники с высокой жаростойкостью.The disadvantage of this method of heat treatment of the rod is the need to coat the inner surfaces of the tank, made of steel plates, with heat-resistant bricks in the case when the temperature of the fluidized bed rises to 600 ° C. In addition, solid particles fly from the surface of the fluidized bed in all directions, which leads to the need to use dust collectors with high heat resistance.

Целью изобретени   вл етс  регулирование механических свойств прутка и повышение эффективности обработки.The aim of the invention is to regulate the mechanical properties of the rod and increase the processing efficiency.

Цель достигаетс  тем, что пруток перемешают через псевдоожиженный слой под углом к горизонтальной плоскости, а врем  термообработки регулируют пугем изменени  длины участка, расположенного в псевдоожиженном слое, , причем прот жку прутка через псевдоожиженный слой осуществл ют наклонно снизу вверх, длину участка прутка, расположенного в псевдоожиженном слое, измен ют за счет изменени  высоты сло  при посто нном угле наклона прутка и за счет изменени  угла наклона прутка при посто нной высоте сло .The goal is achieved by mixing the rod through the fluidized bed at an angle to the horizontal plane, and the heat treatment time is controlled by varying the length of the section located in the fluidized bed, the rod being drawn through the fluidized bed obliquely upwards, fluidized bed, change by changing the height of the layer at a constant angle of inclination of the rod and by changing the angle of inclination of the rod at a constant height of the layer.

Способ термической обработки прутка по сн етс  чертежами, где на фиг. 1 приведен вариант реализации изобретени  дл  изменени  продолжительности выдержки пр/тка в псевдоожиженном слое за счет изменени  его высоты при посто нном угThe bar heat treatment method is illustrated in the drawings, where in FIG. 1 shows an embodiment of the invention for varying the dwell time of a fluidized bed due to a change in its height at a constant angle.
