Description

ТаблицаTable

феррито-перлитной структуры, в которой скорость диффузии намного выше. В результате длительность обработки снижаетс  более чем в 3 раза (15 час вместо 47 по известному способу ). Повышаютс  пластические свойства гор чекатаной арматуры и исключаетс  необходимость проведени  дополнительной ее термической обработки.ferrite-pearlite structure in which the diffusion rate is much higher. As a result, the processing time is reduced by more than 3 times (15 hours instead of 47 by a known method). The plastic properties of hot-rolled reinforcement are enhanced and the need for additional heat treatment is eliminated.

В результате такой обработки арматурные стержни периодического профил  0 2 мм имеют следуюшие механические свойства по сравнению со свойствами стали, обработанной по известному способу {см. табл.).As a result of this treatment, the reinforcing bars of a periodic profile 0 2 mm have the following mechanical properties as compared with the properties of steel processed by a known method {see tab.).
