一、中(zhong)頻透熱(re)(re)(re)(re)爐(lu)線圈(quan)(quan)的作用透熱(re)(re)(re)(re)爐(lu)線圈(quan)(quan)即為透熱(re)(re)(re)(re)爐(lu)的加(jia)熱(re)(re)(re)(re)爐(lu)體，主要(yao)作用就是產生磁(ci)場來切割線圈(quan)(quan)內部的金(jin)屬(shu)，產生渦流而自身(shen)加(jia)熱(re)(re)(re)(re)。透熱(re)(re)(re)(re)爐(lu)線圈(quan)(quan)設計制造水平的高(gao)低決(jue)定了電磁(ci)能(neng)量與熱(re)(re)(re)(re)能(neng)之(zhi)間(jian)轉換的效率高(gao)低，決(jue)定金(jin)屬(shu)加(jia)熱(re)(re)(re)(re)速度(du)(du)快慢、決(jue)定了透熱(re)(re)(re)(re)爐(lu)加(jia)熱(re)(re)(re)(re)的溫(wen)度(du)(du)均勻性。因此，透熱(re)(re)(re)(re)爐(lu)線圈(quan)(quan)在整個透熱(re)(re)(re)(re)爐(lu)系統中(zhong)起(qi)著(zhu)非常重要(yao)的作用，加(jia)熱(re)(re)(re)(re)溫(wen)度(du)(du)一般不超過1250度(du)(du)。

　　二、透(tou)(tou)熱(re)(re)爐(lu)(lu)(lu)線(xian)圈(quan)(quan)的設(she)(she)計(ji)參(can)(can)數(shu)為什么說透(tou)(tou)熱(re)(re)爐(lu)(lu)(lu)線(xian)圈(quan)(quan)設(she)(she)計(ji)復雜、種類(lei)繁多(duo)呢?這與透(tou)(tou)熱(re)(re)爐(lu)(lu)(lu)線(xian)圈(quan)(quan)設(she)(she)計(ji)參(can)(can)數(shu)有(you)很大的關系(xi)。透(tou)(tou)熱(re)(re)爐(lu)(lu)(lu)線(xian)圈(quan)(quan)的設(she)(she)計(ji)參(can)(can)數(shu)與被(bei)加(jia)熱(re)(re)金(jin)(jin)屬的材質、金(jin)(jin)屬比熱(re)(re)能、加(jia)熱(re)(re)溫度、被(bei)加(jia)熱(re)(re)金(jin)(jin)屬的外(wai)形尺(chi)寸、重量以及生產(chan)效率都有(you)著(zhu)直(zhi)接的關系(xi)，被(bei)加(jia)熱(re)(re)金(jin)(jin)屬工件的任(ren)何一個參(can)(can)數(shu)變化都會引起透(tou)(tou)熱(re)(re)爐(lu)(lu)(lu)線(xian)圈(quan)(quan)的匝(za)數(shu)、銅管規格、線(xian)圈(quan)(quan)長度、線(xian)圈(quan)(quan)直(zhi)徑或者線(xian)圈(quan)(quan)形狀發(fa)生變化。

　　三、透熱(re)爐(lu)線(xian)(xian)(xian)圈(quan)(quan)的種類透熱(re)爐(lu)線(xian)(xian)(xian)圈(quan)(quan)一般分為貫通式加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、局部或者(zhe)端部加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、扁平(ping)或者(zhe)橢圓形(xing)加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、鋼板加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、鋼管加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、長棒料加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、方坯加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)、大功率分段式加(jia)熱(re)線(xian)(xian)(xian)圈(quan)(quan)等等。

　　四、透熱爐(lu)線(xian)(xian)圈的結構透熱爐(lu)線(xian)(xian)圈由矩形紫銅(tong)(tong)管按照(zhao)設計的銅(tong)(tong)管規格、直徑、匝數在繞(rao)線(xian)(xian)機上(shang)繞(rao)制而(er)成，線(xian)(xian)圈上(shang)焊有(you)銅(tong)(tong)螺(luo)釘，銅(tong)(tong)螺(luo)釘上(shang)安裝帶(dai)有(you)一定匝間距離的膠木柱，固定線(xian)(xian)圈匝間距離，保(bao)持透熱爐(lu)線(xian)(xian)圈形狀不變(bian)線(xian)(xian)圈上(shang)一般(ban)有(you)噴(pen)涂絕緣漆、纏(chan)(chan)繞(rao)云母帶(dai)、纏(chan)(chan)繞(rao)玻璃絲帶(dai)以及(ji)絕緣漆固化四到絕緣處理，再打結爐(lu)襯(chen)保(bao)護線(xian)(xian)圈，輔助(zhu)于底(di)托固定、不銹(xiu)鋼爐(lu)口板、外圍膠木板、水路、立排(pai)以及(ji)卡扣式連接排(pai)等，形成完整的透熱爐(lu)線(xian)(xian)圈。
