Изобретение относитс к термичесной обработке металлической полосы и проволоки.This invention relates to the thermal treatment of metal strip and wire.
Известен способ термической обработки изделий, заключающийс в том, что мотки проволоки сначала формируго а затем нагреваазт в индукторе тонами промьпдленной частоты.There is a known method of heat treatment of products, which consists in the fact that the coils of wire are first formed and then heated in the inductor with industrial frequency tones.
Однако известный способ нагрева стальной проволоки характеризует неравномерность в распределении температуры витков (слоев) по сечению мотка в радиальном направлении, что приводит к снижению производительности из-за необходимости выравнивани температуры.However, the known method of heating steel wire characterizes the non-uniformity in the temperature distribution of the coils (layers) over the cross section of the coil in the radial direction, which leads to a decrease in productivity due to the need to equalize the temperature.
Цель изобретени - обеспечение равномерности распределени температуры по сечен ю мотва (рулона) и повышение качества изделий, The purpose of the invention is to ensure uniform temperature distribution over the section of the motva (coil) and improve the quality of products,
Это достигаетс тем, что нагрев полосы или проволоки в индукторе по предлагаемому способу провод т одновременно с процессом сматывани их в рулон (моток) во внутренней полости цилиндрического индуктора.This is achieved by the fact that the heating of the strip or wire in the inductor of the proposed method is carried out simultaneously with the process of winding them into a roll (skein) in the internal cavity of a cylindrical inductor.
Пример. Полосу толщиной I мм и шириной 1000 мм из низкоуглеродистой стали, смотаннув в рулон на моталках прокатного стана, передают на специальное перемоточное устройство, моталка которого находитс во внутренней полости индуктора. Полоса задаетс в моталку через специальное технологическое отверстие в индукторе, затем моталву и индуктор включают одновременно . Индуктор выполнен так, что его диаметр, в процессе роста диаметра рулона, растет, сохран при этом посто нство зазора между наружнойExample. A strip with a thickness of I mm and a width of 1000 mm of low carbon steel, coiled on coilers of a rolling mill, is transferred to a special rewinding device whose coiler is located in the inner cavity of the inductor. The strip is set into the coiler through a special technological opening in the inductor, then the coiler and the inductor are turned on simultaneously. The inductor is designed so that its diameter, in the process of growth of the diameter of the coil, increases, while maintaining the constancy of the gap between the outer
Ьонерхноотью нагреваемого рулона и внутренней поверхностью шдунтора. При изменении диаметра нагреваемого рулона о 500 мм до 1300 мм, частоте тона индувтора 1000 гц и температуре нагрева 720°С мощность инду тора должна быть изменена с 1500 ввт до 4150 КВТ, при этом средн окорооть нагрева составит 2,5 кг/сен или 9 т/час. С повышением установочной мощности индуктора реально можноTop of the heated coil and the inner surface of the shduntor. When the diameter of the heated roll is about 500 mm to 1300 mm, the frequency of the inductor's tone is 1000 Hz and the heating temperature is 720 ° C, the power of the inductor should be changed from 1500 kW to 4150 kW, while the average heating volume will be 2.5 kg / sen or 9 t / hour With an increase in the installation power of the inductor, you can really
