Description
(1)潤滑油の平均粒径を1mm未満にし、
(2)粒状の潤滑油と同時に噴射される不燃性ガス(例えば、空気、ヘリウム、窒素、アルゴン、等)の流量を毎分2000cm3以上とし、
(3)ガスの噴射速度を毎秒1m以上とし、
(4)最大潤滑供給量をロール表面積1m2あたり20cm3以下とする、
ことによって、比較的粘度が高い前記高塩基性アルカリ土類金属化合物が混合された潤滑油をガスアトマイズ法によって供給しても、火災を防止しつつ、安全かつ安定した熱間潤滑圧延を実施することができることを発見した。
−ノズルから噴射した潤滑油を極力多くロール表面に付着させる、
−ロール以外の設備に潤滑油が付着しても引火しにくいようにする、
−ノズルから噴射された潤滑油がロールに到達する間に引火しないようにする、
ことである。これをガスアトマイズ供給法で実現するための条件が、
(1)潤滑油の平均粒径を1mm未満にし、
(2)粒状の潤滑油と同時に噴射される不燃性ガス(例えば、空気、ヘリウム、窒素、アルゴン、等)の流量を毎分2000cm3以上とし、
(3)ガスの噴射速度を毎秒1m以上とし、
(4)最大潤滑供給量をロール表面積1m2あたり20cm3以下とする、である。
本願発明者は、熱間転動摩耗試験機を用いて、本発明によるロールの黒皮生成抑制効果および実験中の発火現象有無について調査した。
<実験条件>
・試験片:直径80mm、幅10mm、ハイスロール材製
・相手片:直径165mm、幅15mm、S45C製
・荷重:30kgf
・試験片回転速度:176m/min、相手片速度:185m/min
・試験片摩擦面温度:650℃、相手片摩擦面温度:880℃
・潤滑油:
(a)鉱油に300mgKOH/g塩基度のカルシウムスルフォネートを15体積%配合された潤滑油で、40℃における粘度が110cSt。
(b)鉱油に菜種油を15体積%添加された潤滑油で40℃における粘度が112cStのもの(比較用)。
・供給方法:
(i)ガスアトマイズ法。供給量は約3cm3/m2、ガスは窒素を使用。ガス流量は1000cm3/分と2500cm3/分の2水準、潤滑油の平均粒径は約200ミクロン。毎秒3mの流速。
(ii)0.8%のエマルションとして供給(潤滑油分は3.2cm3/m2供給)。
・転動摩擦時間:10分
<実験結果>
・潤滑油(a)+供給法(i)(流量1000cm3/分)→黒皮厚さ:2μm以下、試験片の一部で発火。
・潤滑油(a)+供給法(i)(流量2500cm3/分)→黒皮厚さ:2μm以下、発火無し。
・潤滑油(a)+供給法(ii) → 黒皮厚さ:3μm程度、発火現象無し。
・潤滑油(b)+供給法(i)(流量1000cm3/分)→黒皮厚さ:8μm程度、発火現象あり。
・潤滑油(b)+供給法(i)(流量2500cm3/分)→黒皮厚さ:8μm程度、発火現象無し。
・潤滑油(b)+供給法(ii) → 黒皮厚さ:9μm程度、発火現象無し。
本願発明者は、2Hi圧延機(2重式圧延機)を用いて、潤滑油供給条件を変化させたときの摩擦係数低減効果を潤滑性能の代表指標として調査するとともに、発火発生限界条件についても圧延実験で調査した。この実験では4つの供給条件において本願発明に基づく基準条件を設け、これを基準に、4つの条件のうち1つの条件について個別に変化させたときの摩擦係数低減効果と発火現象の発現有無について検討した。
・ロール:直径400mm、ハイスロール、胴長100mm
・被圧延材:0.02%炭素鋼、1mm厚×50mm幅×10000m長さ(コイル)
・加熱温度:1000℃(窒素雰囲気)
・圧延速度:50m/min
・ロールギャップ:圧下率換算で20%〜40%
・潤滑油:鉱油に300mgKOH/g塩基度のカルシウムスルフォネートを25体積%配合された潤滑油で、40℃における粘度が110cSt。
・供給条件:噴霧ノズルによる供給。不燃性ガスには窒素を使用。
(a)供給量:0.05〜30cm3/m2(基準条件:2.5cm3/m2)
(b)ガス流量:200cm3/分から10000cm3/分 (基準条件:3000cm3/分)
(c)ガス流速:毎秒0.2m〜毎秒10m (基準条件:毎秒2m)
(d)潤滑油平均粒径:0.02mmから3mm (基準条件:0.8mm)
供給条件(a)の条件を変化させ、(b)、(c)及び(d)の条件を基準条件として圧延実験を行った。図1は潤滑油供給量を変化させた時の摩擦係数低減効果と、実験中に発生した発火現象発現範囲を示すものである。図1に示すように、供給量が20cm3/m2よりも多くなると、供給した潤滑油が発火する現象が観察されたが、本願発明の条件範囲では熱間圧延中、潤滑供給しながら圧延しても供給した潤滑油が発火することなく、またスリップトラブルを引き起こすことなく圧延することができた。供給量が30cm3/m2以上では圧延スリップが発生し圧延できなかった。潤滑効果も少なくとも従来と同等以上の効果が得られることも確認した。
