Description
本發明係有關一種對垂直裝載的線材捲線進行熱處理時所使用之線材捲線用之裝載治具及使用其之線材捲線之熱處理方法。 The present invention relates to a wire coil loading jig used for heat treatment of vertically loaded wire coils and a heat treatment method for wire coils using the same.
在將線材捲繞成捲線狀的線材捲線之熱處理中,加熱用或冷卻用之氣體被沿著捲線之外周流動,而流動在形成線材捲線的線材間之間隙的氣體為極少量。因此,在氣體接觸的線材捲線之表層部與氣體不接觸的內部之間之溫度差極大,而容易產生球化率之惡化、脫碳量之增加等在品質上之問題。 In the heat treatment of the wire coil in which the wire rod is wound into a coil shape, the gas for heating or cooling flows along the outer circumference of the coil wire, and the gas flowing in the gap between the wire rods forming the wire rod coil is very small. Therefore, the temperature difference between the surface layer portion of the wire coil in contact with the gas and the interior portion not in contact with the gas is extremely large, and quality problems such as deterioration of the spheroidization rate and increase of the decarburization amount are likely to occur.
為了縮小在線材捲線內外之溫度差,雖然亦可考慮減緩升溫‧冷卻速度、或延長均熱時間等,但是於此情形下會產生處理時間之延長、運作成本增加之問題。此外,當大氣冷卻時之冷卻速度緩慢之情形下,則容易產生難酸洗性鏽皮(scale),進而降低酸洗性。 In order to reduce the temperature difference between the inside and outside of the wire coil, it is possible to slow down the heating and cooling rate, or extend the soaking time, etc. However, in this case, the problem of prolonging the processing time and increasing the operating cost will occur. In addition, when the cooling rate during atmospheric cooling is slow, a hard-to-pick-washable scale is likely to be generated, thereby lowering the pickling-ability.
作為用來縮小在線材捲線內外之溫度差的手段,於下述專利文獻1中揭示有以下之特徵:藉由設置封閉線材捲線上端之封閉板(蓋部),使自線材捲線之內側空間下方朝上方吹入氣體,自線材捲線之內徑側向外朝外徑側流通,而在短時間且均勻地將線材捲線加熱。然而,專利文獻1所記載之技術內容係以不進行線材捲線之多層裝載為前提者,專
利文獻1並未揭示有用來對多層裝載之線材捲線均勻地進行加熱(冷卻)的具體之構成。
As a means for reducing the temperature difference between the inside and outside of the wire coil, the following
專利文獻1:日本國專利第2913727號公報 Patent Document 1: Japanese Patent No. 2913727
本發明係以如上述之情形作為背景,目的在於提供一種線材捲線用之裝載治具及使用其之線材捲線之熱處理方法,其可改善多層裝載之線材捲線的熱處理時之氣流,且可縮小線材捲線內外之溫度差。 The present invention is based on the above-mentioned circumstances, and aims to provide a wire coil loading jig and a heat treatment method for a wire coil using the same, which can improve the airflow during the heat treatment of the multi-layer loaded wire coil, and can reduce the size of the wire The temperature difference between the inside and outside of the coil.

接著,對垂直裝載捲線體44之熱處理中所使用的熱處理爐及冷卻裝置進行說明。於圖4中,符號50係對垂直裝載捲線體44進行退火處理的分批式熱處理爐。於加熱爐50中,對垂直裝載捲線體44實施加熱→均熱→冷卻之各步驟。然後,使用後述之冷卻裝置80對自加熱爐50被取出之垂直裝載捲線體44實施大氣冷卻(急冷)之步驟。
Next, the heat treatment furnace and the cooling device used for the heat treatment of the vertically mounted
此外,垂直裝載捲線體44之冷卻步驟,可根據需要進行變更。例如,可省略在加熱爐50的冷卻而僅利用後述之冷卻裝置80來實施、或者亦可僅利用加熱爐50來實施而省略在後述之冷卻裝置80的冷卻。
In addition, the cooling step of vertically loading the
加熱爐50具備有圖中左端之裝入取出台52及熱處理室54。熱處理室54係於圖中左前側形成有開口54a,通過開口54a進行垂直裝載捲線體44之裝入及取出。開口54a被設為可藉由門55來封閉。門55係經由鋼絲懸掛於滑輪56,且藉由滑輪56之旋轉而升降。
The
熱處理室54被設為可收納6個垂直裝載捲線體44-1、44-2、…、44-6,且被假想地劃分成收納各垂直裝載捲線體44的6個區域。於各區域中配設有作為搬送手段的輥57。
The
於熱處理室54中,設置有複數個作為加熱室內之氣體的加熱手段之輻射管燃燒器68,且以室內各區域成為既定溫度所設定之方式控制輻射管燃燒器68之輸出。此外,熱處理室54具有已省略圖示之氣體供給配管,可將氮氣、RX氣體等還原性氣體適當地供給至室內。
The
圖5為在與垂直裝載捲線體44之搬送方向呈正交之方向
的熱處理室54之剖面圖,且顯示於室內裝入有垂直裝載捲線體44的狀態。
FIG. 5 is a direction perpendicular to the conveying direction of the
於熱處理室54中,除了輻射管燃燒器68外,亦設置有用來朝垂直裝載捲線體44吹入氣體的氣體循環裝置70。
In the
氣體循環裝置70係具備有管道72、被收納於管道72內部的循環風扇74、及使循環風扇74旋轉驅動的驅動馬達75。如該圖所示,管道72係形成彎曲形狀,於其一端部形成有氣體吹出口72a,該氣體吹出口72a係於垂直裝載捲線體44之正下方朝上方開口。另一方面,於管道72之另一端部形成有朝下方之氣體吸入口72b。循環風扇74被配置在該氣體吸入口72b之正上方位置。此外,符號77係溫度感測器。於本實施形態中,藉由與溫度感測器77連接之控制部(省略圖示),使利用溫度感測器77所檢測氣體之溫度與預先被設定之目標環境氣體溫度一致之方式控制輻射管燃燒器68之燃燒。
The
於如此構成之熱處理室54中,藉由使氣體循環裝置70之循環風扇74旋轉並使利用輻射管燃燒器68被加熱的氣體通過氣體吸入口72b被吸引至管道72內,且自管道72之氣體吹出口72a朝上方吹出。
In the
然後,朝上方之氣流的一部分通過垂直裝載捲線體44之第一氣體流道11被送入至下側線材捲線W1之內側空間W1a內。被送入至下側線材捲線W1之內側空間W1a內的氣體中自內側空間W1a之上端部所流出之氣體藉由第一蓋體8被阻止,然後通過構成下側線材捲線W1的線材之間隙,如箭頭所示自內徑側朝外徑側流通,一面將線材捲線內外之溫度差保持為最小,一面在短時間將下側線材捲線W1加熱至既定之加熱溫度。
Then, a part of the upward airflow is sent into the inner space W1a of the lower wire coil W1 through the first
同樣地,朝上方之氣流的其他一部分通過垂直裝載捲線體44之第二氣體流道13被送入至上側線材捲線W2之內側空間W2a內。被送入至上側線材捲線W2內側空間W2a內之氣體中自內側空間W2a之上端部所流出之氣體藉由第二蓋體9被阻止,然後通過構成上側線材捲線W2的線材之間隙,如箭頭所示自內徑側朝外徑側流通,一面將線材捲線之內外溫度差保持為最小,一面在短時間將上側線材捲線W2亦加熱至既定之加熱溫度。
Similarly, the other part of the upward air flow is sent into the inner space W2a of the upper wire coil W2 through the second
於加熱爐50中,在加熱之後進行均熱及冷卻。於冷卻之步驟中亦與加熱步驟相同,通過構成線材捲線W1、W2的線材之間隙,使既定溫度之氣體自內徑側朝外徑側流通,一面將線材捲線內外之溫度差保持為最小,一面進行下側線材捲線W1及上側線材捲線W2之冷卻。
In the
圖6為顯示用來冷卻垂直裝載捲線體44之冷卻裝置80之構成的圖,且顯示在處理室81內裝入有垂直裝載捲線體44的狀態。於該圖中,符號82係對垂直裝載捲線體44供給朝上方之冷風(大氣)的鼓風機裝置,鼓風機裝置82之氣體吹出口82a被配置在垂直裝載捲線體44之正下方。符號84係形成於處理室81之側壁上部的氣體排出用之配管。
FIG. 6 is a diagram showing the configuration of a
於如此構成之本實施形態之冷卻裝置80中,未被加熱之大氣被作為冷卻用之氣體,自氣體吸入口82b取入,且自鼓風機裝置82之氣體吹出口82a朝上方吹出。
In the
並且,由於朝上方氣流之一部分通過垂直裝載捲線體44之第一氣體流道11而被送入至下側線材捲線W1之內側空間W1a內,並且朝上方氣流之其他一部分通過垂直裝載捲線體44之第二氣體流道13而被送入至上
側線材捲線W2之內側空間W2a內,因此於該冷卻步驟中亦與加熱步驟同樣,通過構成線材捲線W1、W2的線材之間隙,可使冷卻用之氣體自內徑側朝外徑側流通,一面將線材捲線內外之溫度差保持為最小,一面進行下側線材捲線W1及上側線材捲線W2之冷卻。再者,被用來冷卻之氣體通過氣體排出用之配管84而被排出至室外。
In addition, a part of the upward airflow passes through the first
如上所述,根據本實施形態之裝載治具1,其可改善多層被裝載之下側線材捲線W1及上側線材捲線W2中之氣流,縮小熱處理時之捲線內外之溫度差。藉此,根據本實施形態之裝載治具1,其不需要為了縮小溫度差而使升溫速度‧冷卻速度變慢,而可實現急速加熱‧急速冷卻,可縮短熱處理時間,降低運行成本。此外,藉由急速冷卻可抑制難酸洗性鏽皮之生成,而提高酸洗性。
As described above, according to the
此外,於本實施形態之線材捲線用之裝載治具1中,由於第一蓋體8係被設置成可沿第一支柱4之軸向移動,且被載置於下側線材捲線W1之上端,因此,即使因負載崩潰等而造成下側線材捲線W1之上端位置產生變化時,第一蓋體8亦可追隨其變化而維持下側線材捲線W1之上端封閉的狀態。
In addition, in the wire
此外,於本實施形態之線材捲線用之裝載治具1中,在第一支柱4上方且上側線材捲線W2之內側空間W2a內設置第二支柱6,通過被形成在第二支柱6的開口40,氣流被導入至上側線材捲線W2之內側空間W2a。
In addition, in the wire
如此,第二支柱6可抑制上側線材捲線W2因負載崩潰等所引起之變形,並且藉由被形成在第二支柱6的開口40,可控制朝上側線材捲線W2
之內側空間W2a的氣流之吹出方向。
In this way, the
以上,雖然已對本發明之實施形態進行詳細之說明,但是該等僅為一示例而已。例如,用來使氣流通過形成於第一載置板的第一貫通孔及第二貫通孔之形狀及大小,其並不限於上述實施形態,而可適當變更。此外,設於上側線材捲線之內側空間內的第二支柱之形狀及大小,亦可適當地變更,亦可根據情形,採用不設置第二支柱之構成等,本發明可在不脫離其意旨之範圍內,追加各種變更之形態來實施。 The embodiments of the present invention have been described above in detail, but these are merely examples. For example, the shape and size of the first through hole and the second through hole formed in the first mounting plate are not limited to the above-described embodiment, and can be appropriately changed. In addition, the shape and size of the second struts provided in the inner space of the upper wire coil can be appropriately changed, and the structure without the second struts can be adopted depending on the situation. Within the scope, various modifications are added and implemented.
