Description
Изобретение отиоситс к области терме, обработки металлических заготовок, в частности к ипдукциоиным нагревател м дл нагрева углов заготовок пр моугольной формы.The invention relates to the field of processing metal workpieces, in particular, to producing heaters for heating the corners of rectangular billets.
Известен индукционный нагреватель дл иагрева углов пр моугольных заготовок, содержащий пр моугольный водоохлаждаемый ши.хтованный магнитопровод из двух частей П-образ,ной формы, образующих при сопр жении отверстие дл прохождени заготовки, а в каждой из частей магнитопровода выполнено по два параллельных длинной стороне выреза, в которых расположены электрические обмотки.A known induction heater for heating the corners of rectangular billets, comprising a rectangular water-cooled wire. A magnetic core consists of two U-shaped parts, which form an opening for passage of the workpiece when coupled, and in each part of the magnetic core there are two parallel to the long side of the notch in which electric windings are located.
Предлагаемый нагреватель отличаетс от известного тем, что, с целью повыщени надежности , вырезы выполнены в виде окон, электрическа обмотка «амота-на на межокониые перегородки, а «а поверхност х магнитопровода , обращенных к отверстию дл прохождени заготовки, выполнены пазы дл размещени в них труб водоохлаждени .The proposed heater differs from the well-known in that, in order to increase reliability, the cutouts are made in the form of windows, the electrical winding of the “amoton on interglacial partitions,” and the surfaces of the magnetic conductor facing the opening for the passage of the workpiece are made water cooling pipes.
На чертеже представлен индукционный нагреватель , поперечный разрез.The drawing shows an induction heater, a cross-section.
Магнитопровод состоит из двух частей / и 2, набранных из железных пластин, периодически чередуемых с медными, которые П-ри сопр жении образуют центральное отверстие 3The magnetic circuit consists of two parts / and 2, assembled from iron plates, periodically alternating with copper plates, which, in conjunction with the junction, form a central hole 3
дл прохождени обрабатываемой заготовкиfor the passage of the workpiece
4нр моугольиого понеречного сечени . Кажда нз частей магнитопровода и.меет полюса4nr of mongolian river section. Each nz of parts of the magnetic circuit and has a pole
5и 6, которые выступают к обрабатываемой заготовке в верхней и нижней част х отверсти 3. Кажда из частей магнитопровода имеет пару окон 7 н 8, между которыми образуютс межоконные перегородки 9, на которые наматываютс электрические обмотки 10.5 and 6, which protrude to the workpiece in the upper and lower parts of the opening 3. Each of the parts of the magnetic circuit has a pair of windows 7 and 8, between which inter-window partitions 9 are formed, on which electrical windings 10 are wound.
Витки обмотки охлаждаютс водой и изолированы один от другого. На поверхност х магнитопровода, обращенных к отверстию дл прохождени заготовки, выполнены пазы // дл размещени в них труб J2 водоохлаждени магнитопровода.The coils of the winding are cooled with water and isolated from one another. Grooves are made on the surfaces of the magnetic conductor facing the hole for passage of the workpiece to accommodate the water-cooling pipes J2.
В процессе работы индукционного нагревател перегородка 13 полностью защищает обмотку W от нагрева излучением и от окаЛИНЫ , лет щей с обрабатывае.мой заготовки. Перегородки 13 относительно тонкие (Д дюйма ) « щуитируют незначительную часть магнитного потока до насыщенн , после чего они действуют как открытые щели. Поскольку перегородки 13 подвергаютс интенсивному 1нагреву , они охлаждаютс с помощью труб 13. Медные пластины, вставленные в магнитопровод , также помогают отводу тепла, так как увеличивают удельную теплопроводность магнитопровода .During the operation of the induction heater, the baffle 13 completely protects the winding W from heating by radiation and from the scale flying through the workpiece. Partitions 13 are relatively thin (D in.) "Schuitter a small part of the magnetic flux to saturated, after which they act as open slits. Since the barriers 13 are subjected to intense heating, they are cooled with the help of pipes 13. Copper plates inserted into the magnetic core also help in heat removal, since they increase the thermal conductivity of the magnetic core.
