Description

本発明はバッチ式熱処理炉の熱処理間時間決定方法に関し、特に、先行する熱処理工程とこれに続く熱処理工程との間の熱処理間時間を適正に決定できる熱処理間時間決定方法に関する。  The present invention relates to a method for determining the time between heat treatments of a batch heat treatment furnace, and more particularly, to a method for determining the time between heat treatments, which can appropriately determine the time between heat treatments between a preceding heat treatment step and a subsequent heat treatment step.

バッチ式熱処理炉では先行する熱処理工程（以下、第１熱処理工程という）を終えるとワークを搭載した台車を炉内から引き出し、台車上のワークを冷却装置へ移送して冷却した後、再び台車に載せて炉内へ装入して続く熱処理工程（以下、第２熱処理工程という）を行なう。   In a batch type heat treatment furnace, after the preceding heat treatment process (hereinafter referred to as the first heat treatment process) is completed, the carriage on which the work is mounted is pulled out of the furnace, the work on the carriage is transferred to a cooling device, cooled, and then returned to the carriage. A subsequent heat treatment step (hereinafter referred to as a second heat treatment step) is performed after being placed in the furnace.

なお、特許文献１には、熱延到着鋼材と、以降の鋼材の到着予定時刻に基づいて熱片加熱炉と冷片加熱炉のスケジュールを作成することによって、熱片装入開始タイミングと装入可能鋼材を適切に予測し、トラックタイムの短い熱片をスケジュールに組み込むことによって適正な加熱炉への装入・抽出のスケジュールを作成できるようにした加熱・圧延スケジュール作成方法が提案されている。   In addition, in Patent Document 1, a hot piece charging start timing and a charging time are prepared by creating a hot piece heating furnace and a cold piece heating furnace schedule based on the arrival time of the hot rolled arrival steel material and the subsequent steel materials. There has been proposed a heating / rolling schedule creation method in which possible steel materials are appropriately predicted, and a heating and rolling schedule with a short track time is incorporated into the schedule so that an appropriate charging / extracting schedule for the furnace can be created.

ところで、上記従来のバッチ式熱処理炉における、第１熱処理工程と第２熱処理工程の間の熱処理間時間の決定は、実際の台車冷却に要する時間や、ワーク冷却方法による所要時間の相違等が考慮されていなかったため、予想した全体の処理時間と実際の処理時間との間に齟齬が生じて、次工程との連携や生産計画の精度が損なわれるという問題があった。   By the way, in the conventional batch type heat treatment furnace, the determination of the time between heat treatments between the first heat treatment step and the second heat treatment step takes into consideration the time required for actual carriage cooling, the difference in time required depending on the work cooling method, and the like. Since this was not done, there was a problem between the predicted overall processing time and the actual processing time, and there was a problem that cooperation with the next process and accuracy of the production plan were impaired.

そこで、本発明はこのような課題を解決するもので、熱処理間時間を適正に決定して、次工程との良好な連携や生産計画の精度を確保することができるバッチ式熱処理炉の熱処理間時間決定方法を提供することを目的とする。   Therefore, the present invention solves such a problem, and appropriately determines the time between heat treatments to ensure good cooperation with the next process and the accuracy of the production plan. An object is to provide a time determination method.

A method for determining a time between heat treatment steps to the subsequent second heat treatment step, where the difference between the start temperature and the end temperature is determined when the start temperature of the second heat treatment step is lower than the end temperature of the first heat treatment step. When the start temperature of the second heat treatment step is equal to or higher than the end temperature of the first heat treatment step, the value obtained by dividing the value by the furnace cooling rate determined in advance according to the size of the furnace is the carriage cooling time. A step of setting the time to 0, and if the bogie cooling time is larger than an additional time predetermined in accordance with a work cooling method, the sum of the bogie cooling time and the loading time on the bogie is calculated as the time between the heat treatments. Determined as That one, when the carriage cooling time is less than the additional time and determining the sum of time loading the with the additional time as between the heat treatment time.

本第１発明においては、熱処理間時間を台車冷却時間やワーク冷却方法に応じて定めた追加時間を考慮して行なうから、予想した処理時間と実際の処理時間との間の齟齬が小さく抑えられ、次工程との連携や生産計画の精度が維持される。   In the first invention, since the time between heat treatments is performed in consideration of the additional time determined according to the bogie cooling time and the work cooling method, the difference between the predicted processing time and the actual processing time can be kept small. The linkage with the next process and the accuracy of the production plan are maintained.

本第２発明では、前記第１熱処理工程と前記第２熱処理工程の間に更に新たな第３熱処理工程が設定された場合に、前記第１熱処理工程とこれに続く前記第３熱処理工程においては当該第３熱処理工程を本第１発明における前記第２熱処理工程としてこれら熱処理工程の間の熱処理間時間を本第１発明の各ステップで決定するとともに、前記第３熱処理工程とこれに続く前記第２熱処理工程においては前記第３熱処理工程を本第１発明における前記第１熱処理工程としてこれら熱処理工程の間の熱処理間時間を本第１発明の各ステップで決定する。 In the second invention, when further new third heat treatment step between the first heat treatment step and the second heat treatment step is set in the first heat treatment step and the third heat treatment step following this The third heat treatment step is used as the second heat treatment step in the first invention, and the heat treatment time between these heat treatment steps is determined in each step of the first invention, and the third heat treatment step and the subsequent second heat treatment step are performed. In the second heat treatment step, the third heat treatment step is used as the first heat treatment step in the first invention, and the time between heat treatment steps is determined in each step of the first invention .

本第２発明では、前後の熱処理工程の間に新たな熱処理工程が設定された場合にも、予想処理時間と実際の処理時間との間の齟齬が小さく抑えられて、次工程との連携や生産計画の精度が維持される。   In the second invention, even when a new heat treatment process is set between the preceding and following heat treatment processes, the wrinkle between the expected treatment time and the actual treatment time is kept small, The accuracy of the production plan is maintained.

本発明方法はコンピュータで実現され、そのモニタ上の表示の一例を図１に示す。本実施形態では複数のバッチ式熱処理炉１号炉〜３号炉が備えられており、各炉について、熱処理工程１１〜１４，２１〜２４，３１〜３４のタイムチャートが表示されている。なお、本実施形態のバッチ式熱処理炉は既述したものと同様に、先行する熱処理工程（第１熱処理工程）を終えるとワークを搭載した台車を炉内から引き出し、台車上のワークを冷却装置へ移送して冷却した後、再び台車に載せて炉内へ装入して続く熱処理工程（第２熱処理工程）を行なうものである。   The method of the present invention is realized by a computer, and an example of the display on the monitor is shown in FIG. In this embodiment, a plurality of batch-type heat treatment furnaces No. 1 to No. 3 are provided, and time charts of the heat treatment steps 11 to 14, 21 to 24, and 31 to 34 are displayed for each furnace. In addition, the batch type heat treatment furnace of the present embodiment is similar to the one described above, and after the preceding heat treatment step (first heat treatment step) is completed, the carriage on which the workpiece is mounted is pulled out from the furnace, and the workpiece on the carriage is cooled by the cooling device. After being transferred to and cooled, the heat treatment step (second heat treatment step) is carried out after being placed on the carriage again and charged into the furnace.

図１において、各熱処理工程１１〜１４，２１〜２４，３１〜３４の長さは、予熱や本熱処理等の処理パターンに基づいて予め決定された処理時間に応じたものとなっている。この場合の、タイムチャートで表示された前後する熱処理工程（図２にＸａ，Ｘｂで示す）、すなわち第１熱処理工程Ｘａと第２熱処理工程Ｘｂの間の、熱処理間時間Ｘｈは、図３にフローチャートを示す以下の手順で決定されている。   In FIG. 1, the length of each heat treatment process 11-14, 21-24, 31-34 respond | corresponds to the processing time previously determined based on processing patterns, such as preheating and this heat processing. In this case, the heat treatment steps before and after displayed in the time chart (indicated by Xa and Xb in FIG. 2), that is, the inter-heat treatment time Xh between the first heat treatment step Xa and the second heat treatment step Xb are shown in FIG. It is determined by the following procedure showing a flowchart.

図３において、ステップ１００〜３００では、台車冷却時間を決定する。台車冷却時間は、第１熱処理工程Ｘａの終了温度（第１温度）と第２熱処理工程Ｘｂの開始温度（第２温度）の比較で算出方法が異なる。すなわち、第１温度＞第２温度の場合には、下式（１）によって算出する（ステップ１００，２００）。
台車冷却時間＝（第１温度−第２温度）／炉冷却速度…（１）
ここで、炉冷却速度は本実施形態においては、当該炉が大型炉か小型炉かによって表１に示すように予め定められている。一方、第１温度≦第２温度の場合には台車冷却時間は０に設定される（ステップ１００，３００）。 In FIG. 3, in steps 100 to 300, the bogie cooling time is determined. The method for calculating the dolly cooling time differs depending on the comparison between the end temperature (first temperature) of the first heat treatment step Xa and the start temperature (second temperature) of the second heat treatment step Xb. That is, when the first temperature> the second temperature, the following equation (1) is used (steps 100 and 200).
Bogie cooling time = (first temperature−second temperature) / furnace cooling rate (1)
Here, in this embodiment, the furnace cooling rate is predetermined as shown in Table 1 depending on whether the furnace is a large furnace or a small furnace. On the other hand, if the first temperature ≦ the second temperature, the cart cooling time is set to 0 (steps 100 and 300).

Figure 0005609099

続くステップ４００では、上記台車冷却時間と、冷却方法によって予め定められた追加時間とを比較し、台車冷却時間＞追加時間の場合には下式（２）によって熱処理間時間を算出し（ステップ５００）、台車冷却時間≦追加時間の場合には下式（３）によって熱処理間時間を決定する（ステップ６００）。本実施形態では、上記追加時間は表２に示すように水冷、油冷、その他（空冷等）の三種の冷却方法に応じて予め定められている。また、下式（２）、（３）中、台車積込み時間は本実施形態では０．５時間の一定値に設定されている。
熱処理間時間＝台車冷却時間＋台車積込み時間…（２）
熱処理間時間＝追加時間＋台車積込み時間…（３） In subsequent step 400, the bogie cooling time is compared with an additional time determined in advance by the cooling method, and when the bogie cooling time> the additional time, the time between heat treatments is calculated by the following equation (2) (step 500). ) When the cart cooling time ≦ the additional time, the time between heat treatments is determined by the following equation (3) (step 600). In the present embodiment, as shown in Table 2, the additional time is determined in advance according to three cooling methods such as water cooling, oil cooling, and other (air cooling, etc.). In the following formulas (2) and (3), the truck loading time is set to a constant value of 0.5 hours in this embodiment.
Heat treatment time = cart cooling time + cart loading time ... (2)
Time between heat treatments = additional time + truck loading time ... (3)

このような手順によって、熱処理間時間Ｘｈが、実際の台車冷却に要する時間や、ワーク冷却方法による所要時間（追加時間）の相違等を考慮することによって適正に決定される。   By such a procedure, the heat treatment time Xh is appropriately determined by taking into consideration the time required for actual bogie cooling, the difference in required time (additional time) depending on the work cooling method, and the like.

なお、本実施形態ではさらに、モニタ画面上で、ある熱処理工程をマウスクリックして、これをドラッグアンドドロップ（図１の白矢印）により同一炉ないし他の炉の任意の熱処理工程位置に移動させることができる。そして、移動させた熱処理工程を第３熱処理工程として、第１熱処理工程とこれに続く第３熱処理工程との間、および第３熱処理工程とこれに続く第２熱処理工程との間の熱処理間時間の決定を、上記ステップ１００〜６００と同様の手順で再度行なう。この場合も、前後の熱処理工程Ｘａ，Ｘｂの間の熱処理間時間Ｘｈが適正に決定されて、これに応じてモニタ画面上に表示されたタイムチャートの、各熱処理工程１１〜１４，２１〜２４，３１〜３４の表示位置が修正変更される。   In the present embodiment, a certain heat treatment process is further clicked on the monitor screen with a mouse click, and this is moved to an arbitrary heat treatment process position in the same furnace or another furnace by drag and drop (white arrow in FIG. 1). be able to. Then, the transferred heat treatment step is defined as a third heat treatment step, and the time between heat treatments between the first heat treatment step and the subsequent third heat treatment step and between the third heat treatment step and the subsequent second heat treatment step. Is again determined in the same procedure as in steps 100 to 600 above. Also in this case, the heat treatment time Xh between the preceding and following heat treatment steps Xa and Xb is appropriately determined, and the heat treatment steps 11 to 14 and 21 to 24 of the time chart displayed on the monitor screen in accordance with this are determined. , 31 to 34 are corrected and changed.

上記実施形態では熱処理炉が３基の場合について説明したが、１基の場合、２基の場合、あるいは４基以上の場合にも本発明を適用することができる。 Although the case where there are three heat treatment furnaces has been described in the above embodiment, the present invention can be applied to the case of one, two, or four or more.
