本発明は鋼帯の連続溶融金属めっきに用いられるめっき
浴槽に関する。DETAILED DESCRIPTION OF THE INVENTION [Field of Industrial Application] The present invention relates to a plating bath used for continuous hot-dip metal plating of steel strips.
〔従来の技術)
従来の鋼帯の連続溶融金属めっきに用いられるめっき浴
槽を、第4図に示した縦断面説明図を用いて説明する。[Prior Art] A conventional plating bath used for continuous hot-dip metal plating of steel strips will be described with reference to a vertical cross-sectional view shown in FIG.
鋼帯lは、前処理炉2を通過してめっき浴槽3内に浸漬
されジンクロール4により上方へ転回し、めっき浴槽3
から出たところで気体絞り用ノズル5により溶融金属目
付量の制御を行い次工程へ送られる。The steel strip 1 passes through a pretreatment furnace 2, is immersed in a plating bath 3, is turned upward by a zinc roll 4, and is immersed in a plating bath 3.
When the molten metal comes out, the weight of the molten metal is controlled by the gas restricting nozzle 5, and the molten metal is sent to the next step.
めっき浴槽3内の溶融金属は鋼帯lに付着して浴外へ持
ち出されるので、その分を補給するために溶融金属の原
料となる固体金属6(例えばインゴット)を固体金属装
入装置7を用いめっき浴槽3内に装入する。The molten metal in the plating bath 3 adheres to the steel strip l and is taken out of the bath, so in order to replenish the amount, a solid metal 6 (for example, an ingot), which is a raw material for the molten metal, is transferred to the solid metal charging device 7. It is charged into the plating bath 3.
めっき浴槽3には、固体金属6を溶解し溶融金属の温度
を所定の温度に制御するために溶融金属加熱装置8が設
置されており、この加熱装置の加熱源は電熱ヒータまた
は誘導加熱によるものが一般的である。A molten metal heating device 8 is installed in the plating bath 3 in order to melt the solid metal 6 and control the temperature of the molten metal to a predetermined temperature, and the heating source of this heating device is an electric heater or induction heating. is common.
ところで、溶融金属の温度を制御することは以下に示す
2点の理由で非常に重要である。By the way, controlling the temperature of molten metal is very important for the following two reasons.
(1)気体絞り用ノズル5により溶融金属の目付量の制
御を行うに際し、溶融金属の粘度が変化することは目付
量制御の大きな外乱となり、溶融金属の温度が変化する
と粘度も変化する。(1) When controlling the basis weight of the molten metal with the gas throttling nozzle 5, changes in the viscosity of the molten metal become a major disturbance to the basis weight control, and as the temperature of the molten metal changes, the viscosity also changes.
(2)めっき槽3内において鋼帯Iから鉄が溶融金属内
に常に溶出しているが、溶融金属の温度が低下すると平
衡状態が崩れて、ドロスと称する溶融金属と鉄との化合
物が析出し、これが鋼帯1の表面に付着すると傷等の表
面欠陥となる。(2) Iron is constantly leached into the molten metal from the steel strip I in the plating tank 3, but when the temperature of the molten metal drops, the equilibrium state is disrupted and a compound of molten metal and iron called dross is precipitated. However, if this adheres to the surface of the steel strip 1, it will cause surface defects such as scratches.
しかし、第4図に示した従来のめっき浴槽3においては
、いかに加熱装置8によって溶湯金属の温度を制御しよ
うとしても、例えば固体金属6が溶解している部分にお
いては温度が原理的に固体金属の融点にまで下がるので
、めっき浴槽3内の溶融金属には必ず温度差が発生し、
前述した2点の問題点は完全には解決できない。However, in the conventional plating bath 3 shown in FIG. 4, no matter how much the heating device 8 attempts to control the temperature of the molten metal, for example, in the area where the solid metal 6 is melted, the temperature is in principle lower than that of the solid metal. Since the temperature drops to the melting point of the molten metal in the plating bath 3, a temperature difference will always occur in the molten metal in the plating bath 3.
The two problems mentioned above cannot be completely solved.

のでメンテナンス費用も増加する。On the other hand, in Japanese Patent Application Laid-Open No. 1-165753, a bath dedicated to melting solid metal is installed separate from the plating bath 3,
A method has been proposed in which the molten metal melted in the bath is supplied to the plating bath using a pump, but this method complicates the equipment, increases equipment costs, and increases maintenance costs as the pump is corroded by the molten metal.

Another object of the present invention is to provide a plating bath for use in continuous hot-dip metal plating, which has low maintenance costs.

である。[Means for Solving the Problems] In order to solve the above problems, the present invention provides a plating bath in which hot-dip metal plating is performed by continuously immersing a steel strip in the plating bath, in which there are two or more plating baths. The chamber is divided into two chambers, one of which is a supply section for the solid metal that is the raw material for molten metal, and the other is an immersion section for the steel strip, allowing molten metal to flow from the supply section to the immersion section. The present invention provides a plating bathtub used for continuous molten metal plating, characterized in that it is equipped with a heating device capable of independently controlling the temperature of molten metal in each divided room.
[作用]
本発明のめっき浴槽を、その縦断面説明図を示す第1図
を用いて説明する。[Function] The plating bath of the present invention will be explained using FIG. 1, which shows a vertical cross-sectional view thereof.
めっき浴槽3内に高さが鋼帯浸漬部3bの浴面より少し
高い仕切りせき9を設置し、このせき9によってめっき
浴槽3は固体金属供給部3aと鋼帯浸漬部3bに分割さ
れており、供給部3aと浸漬部3bには各々別個に加熱
装置8a、8bが設置されている。A partition weir 9 whose height is slightly higher than the bath surface of the steel strip immersion section 3b is installed in the plating bath 3, and the plating bath 3 is divided into a solid metal supply section 3a and a steel strip immersion section 3b by this weir 9. Heating devices 8a and 8b are separately installed in the supply section 3a and the dipping section 3b, respectively.
めっき浴槽3がこのように構成されているので、固体金
属6の溶解は供給部加熱装置8aによって行われ、浸漬
部3bの溶融金属の温度制御は浸漬部加熱装置8bによ
って行われる。Since the plating bath 3 is configured in this way, the solid metal 6 is melted by the supply section heating device 8a, and the temperature of the molten metal in the immersion section 3b is controlled by the immersion section heating device 8b.
供給部3aにおいては固体金属6の投入量の分だけ浴面
が上昇し、一方浸漬部3bにおいては鋼帯1への目付量
の分だけ浴面が低下する。よって、溶融金属は、供給部
3aから浸漬部3bへ仕切りせき9をオーバーフローし
て流出する。In the supply section 3a, the bath level rises by the amount of solid metal 6 introduced, while in the immersion section 3b, the bath level decreases by the amount of basis weight applied to the steel strip 1. Therefore, the molten metal overflows the partition weir 9 from the supply section 3a to the immersion section 3b.
供給部3aにおいては前述の問題点と同様に溶融金属の
温度分布が発生するが、せき9のオーバーフロ一部近辺
の溶融金属温度を測定して、供給部3aから浸漬部3b
に流出する溶融金属温度を浸漬部3bの溶融金属の温度
と等しくなるように供給部加熱装置8aを制御すれば前
述の問題点は解消できる。In the supply section 3a, temperature distribution of the molten metal occurs in the same manner as the above-mentioned problem, but by measuring the temperature of the molten metal near the overflow part of the weir 9,
The above-mentioned problem can be solved by controlling the supply section heating device 8a so that the temperature of the molten metal flowing out is equal to the temperature of the molten metal in the immersion section 3b.
また、鋼帯lからの鉄の溶出はもっばら浸漬部3bにお
いて生じ、鉄の溶出した溶融金属は供給部3aの方へは
逆流しないので供給部3a内にある溶融金属には鉄分が
含まれず、前述のように供給部3aの内に温度差が生じ
てもドロスは発生しない。Further, the elution of iron from the steel strip l occurs mostly in the immersion section 3b, and the molten metal from which the iron has eluted does not flow back toward the supply section 3a, so the molten metal in the supply section 3a does not contain iron. As described above, even if a temperature difference occurs within the supply section 3a, no dross is generated.
また、浸漬部3には固体金属が供給されないので溶融金
属内に温度の低い部分を生ずることがなく、したがって
ドロスが発生せずめっき鋼帯表面の傷を生ずることがな
い。Further, since no solid metal is supplied to the immersion section 3, no low temperature areas are created in the molten metal, and therefore no dross is generated and no scratches are generated on the surface of the plated steel strip.
せき9をオーバーフローする溶融金属が落差少なく浸漬
部3bに入るには、固体金属6の供給量を浸漬部におけ
る溶融金属の消費量とマツチさせる。落差が太き(なる
と大気が溶融金属に巻き込まれ易(なり、ドロスが発生
し易(なる。In order for the molten metal overflowing the weir 9 to enter the immersion section 3b with a small head, the supply amount of the solid metal 6 is made to match the consumption amount of molten metal in the immersion section. If the head is large, the atmosphere is likely to get caught up in the molten metal, and dross is likely to occur.

ることができる。In the present invention, the plating bath 3 is constructed by using a partition box 10 as shown in FIG. , 9b, it can be divided into two or more parts.
本発明のめっき浴槽は、鋼帯の連続溶融亜鉛めっき等に
好適に使用される。The plating bath of the present invention is suitably used for continuous hot-dip galvanizing of steel strips.

。[Example 1 Example 1 An example in which the present invention is applied to a hot-dip galvanized steel bathtub in which the galvanized bathtub is divided into two rooms by a partition, is shown in FIG. I will explain using
操業条件は、鋼帯lのサイズは1mm厚×1000mm
幅、進行速度は100mpm、目付量は両面合計で20
0 g / rri″である。The operating conditions are that the size of the steel strip is 1mm thick x 1000mm.
The width and traveling speed are 100mpm, and the total basis weight on both sides is 20
0 g/rri''.
鋼帯1は460℃の温度でめっき浴槽3の浸漬部3bに
進入し、浸漬部3b内の溶融亜鉛は460℃になるよう
に加熱装置8bで制御されている。The steel strip 1 enters the immersion section 3b of the plating bath 3 at a temperature of 460.degree. C., and the molten zinc in the immersion section 3b is controlled by a heating device 8b to have a temperature of 460.degree.
一方、めっき浴槽の供給部3aにおいては、加熱装置8
aによって、亜鉛インゴット6を溶解しつつ浸漬部3b
への流出する溶融亜鉛の温度は460℃に制御されてい
る。On the other hand, in the supply section 3a of the plating bath, the heating device 8
a, while melting the zinc ingot 6, the immersion section 3b
The temperature of the molten zinc flowing out is controlled at 460°C.
このような操業条件においては、浸漬部3bにおいて鋼
帯lに付着して持出される亜鉛の量は1200kg/h
であり、この量に対応して供給部3 a il:おいて
は、1000kg単位の亜鉛インゴット6が50分に1
回ずつ、平均1200kg/hになるように装入される
。Under such operating conditions, the amount of zinc attached to the steel strip l in the immersion section 3b and taken out is 1200 kg/h.
Corresponding to this amount, in the supply section 3 ail: 1000 kg of zinc ingot 6 is delivered every 50 minutes.
It is charged at an average of 1200 kg/h each time.
加熱装置8a、8bの所要電力は、8aが190kW、
8bが90kWであった。The required power for the heating devices 8a and 8b is 190kW for 8a,
8b was 90kW.
この時、供給部3aにおける溶融亜鉛内の温度差は、約
30℃あったが、浸漬部3bの方へ流出する亜鉛温度は
460±2℃の範囲で一定であった。また浸漬部3bに
おいては、浸漬部からの放散熱量に相当する分だけ加熱
装置8bから加熱するだけであり、溶融亜鉛内部の温度
差も460±2℃の範囲におさまった。At this time, the temperature difference in the molten zinc in the supply section 3a was about 30.degree. C., but the temperature of the zinc flowing out toward the immersion section 3b was constant within the range of 460.+-.2.degree. Further, in the immersion section 3b, only the heating device 8b heated the immersion section by an amount corresponding to the amount of heat dissipated from the immersion section, and the temperature difference inside the molten zinc was within the range of 460±2°C.
このような状況において溶融亜鉛への鉄の溶出は浸漬部
3bにおいてのみ発生するが、溶融亜鉛内部の温度差が
ほとんどないのでドロスの発生が激減した。また、溶融
亜鉛は浸漬部3bから供給部3へ逆流せず、供給部3a

大きくてもドロスの発生は皆無であった。以上の結果を
、第4図に示す従来装置を用いた場合と比較して第1表
にまとめて示す。なお、表面傷発生率は鋼帯製品を目視
で観察し、傷が1カ所でもついた鋼帯を「傷鋼帯」と定
義して、製造全鋼帯に対する比率により求めた。In such a situation, iron elution into the molten zinc occurs only in the immersion section 3b, but since there is almost no temperature difference inside the molten zinc, the generation of dross is drastically reduced. Further, the molten zinc does not flow back from the immersed part 3b to the supply part 3, and the molten zinc does not flow back to the supply part 3a.
Since there was no iron leached out, no dross was generated even when the temperature difference was large as mentioned above. The above results are summarized in Table 1 in comparison with the case using the conventional device shown in FIG. Incidentally, the surface flaw occurrence rate was determined by visually observing the steel strip product, defining a steel strip with even one flaw as a "scarred steel strip", and determining the ratio to the total manufactured steel strip.
ドロス発生量が175になり、その結果表面傷の発生率
も半減した。また、目付量のばらつきもわずかではある
が減少できた。The amount of dross generated was reduced to 175, and as a result, the incidence of surface scratches was also halved. In addition, the variation in basis weight was also reduced, albeit slightly.
