Description
本発明は、スラブ鋳造技術分野に関し、特に連続鋳造スラブ凝固端を高圧圧下した連続鋳造機扇状セグメント及びその高圧圧下方法である。 The present invention relates to the technical field of slab casting, and more particularly, to a continuous caster fan segment in which a continuous cast slab solidification end is subjected to high pressure reduction and a high pressure reduction method thereof.
連続鋳造スラブ凝固端高圧圧下技術は、連続鋳造生産ラインに連続鋳造スラブに圧下ローラーを設置し、鋳造スラブ中心部の固相率が８０％以上に達すると、鋳造スラブに高圧圧下変形（５〜２０ｍｍ）を印加し、その後正常な圧延生産を行うことである。該技術により連続鋳造スラブの中心部品質を大幅に向上でき（マクロ構造、収縮、緩み、偏析などを改善する）、低い圧縮比（１．５〜２．５）で高品質の厚さが１００ｍｍより大きい超厚板製品を製造することができる。
連続鋳造スラブ凝固端に高圧圧下を実施した場合、鋳造機扇状セグメントに対して全体高圧圧下を行うと、扇状セグメントの５〜７対の鋳造機ローラーが同時に鋳造スラブに接触する場合の接触面積が大幅に増加し、それによって負荷も大幅に増大するので、扇状セグメントの強度及び剛性を大幅に増加しなければ扇状セグメント及びセグメントローラー（又は鋳造機ローラー）への強力な負荷及び大きな弾性変形に抵抗できず、セグメントローラーがローラーリング、芯軸及び中間支持ベアリング台座で構成されるので、扇状セグメントのサイズ及び重量が大幅に増加し、これにより扇状セグメントの吊り上げ及びメンテナンスなどの一連の新しい問題をもたらし、かつ高圧圧下が連続鋳造スラブ凝固端の近傍に実施され、扇状セグメントを高圧圧下する複数対のローラー、小変形低圧圧下によって発生した変形（歪み）透過性が悪く、鋳造スラブ中心部領域に伝達された歪みが小さいので、中心部領域の緩み及び偏析欠陥をより良く改善するのに役立たない。
そのため、直接元の連続鋳造機の低圧圧下システムで扇状セグメントに凝固端高圧圧下を実施すると、連続鋳造機の扇状セグメント、駆動ローラーの強度及び鋼性が深刻に不足し、及びクランプシリンダの担持能力が十分ではなく、凝固端高圧圧下を実施しにくく、かつ連続鋳造スラブの中間に亀裂が容易にできるなどの問題が発生する。
In the continuous casting slab solidification end high pressure reduction technology, a pressure reduction roller is installed on the continuous casting slab in the continuous casting production line, and when the solid phase percentage of the casting slab central portion reaches 80% or more, high pressure 20 mm) and then perform normal rolling production. The technology can greatly improve the central quality of continuously cast slabs (ameliorates macro structure, shrinkage, looseness, segregation, etc.), high compression thickness 100 mm with low compression ratio (1.5 to 2.5) Larger ultra-thick board products can be manufactured.
When high pressure is applied to the solid casting end of the continuous casting slab, the contact area when 5 to 7 pairs of caster rollers of the fan segment simultaneously contact the cast slab when the entire high pressure is applied to the caster fan segment Because it significantly increases and thereby significantly increases the load, it resists strong loads and large elastic deformation on the fan segment and segment roller (or caster roller) unless the strength and stiffness of the fan segment is significantly increased. No, and because the segment roller is composed of the roller ring, core shaft and intermediate support bearing pedestal, the size and weight of the fan segment is greatly increased, which brings a series of new problems such as lifting and maintenance of the fan segment And high pressure reduction is carried out near the solidification end of the continuous casting slab, Because the deformation (strain) permeability generated by multiple pairs of rollers under high pressure reduction, small deformation and low pressure reduction is poor, and the strain transmitted to the cast slab central region is small, the looseness and segregation defects in the central region are better improved It is not useful to do.
Therefore, if solid pressure high pressure reduction is performed on the fan-shaped segment directly in the low pressure reduction system of the original continuous caster, the strength of the fan-shaped segment of the continuous caster, the drive roller and the steelability are seriously lacking, and the carrying capacity of the clamp cylinder However, problems such as difficulty in carrying out solidification end high pressure reduction and easy cracking in the middle of continuous cast slabs occur.
本発明が解決しようとする技術的問題は連続鋳造スラブ凝固端を高圧圧下した連続鋳造機扇状セグメント及びその高圧圧下方法を提供し、従来技術において元の連続鋳造機システムを用いて扇状セグメントに凝固端高圧圧下を実施すると、連続鋳造機の扇状セグメント、駆動ローラーの強度及び鋼性が深刻に不足であり、及びクランプシリンダの担持能力が十分ではなく、凝固端高圧圧下を実施しにくく、かつ鋳造スラブの中間に亀裂が容易にできるなどの問題を解決することである。 The technical problem to be solved by the present invention is to provide a continuous caster fan segment in which a continuous cast slab solidifying end is reduced under high pressure and a high pressure reduction method thereof, and solidify into the fan-shaped segment using the original continuous caster system in the prior art. When the end high pressure reduction is carried out, the strength and the rigidity of the fan-shaped segment of the continuous caster, the driving roller are seriously lacking, and the carrying capacity of the clamp cylinder is not sufficient. It is an object of the present invention to solve problems such as easy cracking in the middle of slabs.
上記の技術的問題を解決するために、本発明の実施例による連続鋳造スラブ凝固端を高圧圧下した連続鋳造機扇状セグメントは、連続鋳造機扇状セグメントに位置する上枠、下枠、上駆動ローラー、下駆動ローラー、左従動ローラー群、右従動ローラー群、圧下装置及びクランプシリンダを含み、前記クランプシリンダが上枠と下枠をクランプして設定された間隔を維持することに用いられ、前記上駆動ローラーが圧下装置に接続され、前記上駆動ローラーが上ベアリング台座を介して上枠に接続され、前記下駆動ローラーが下ベアリング台座を介して下枠に接続され、前記左従動ローラー群及び前記右従動ローラー群がそれぞれ駆動ローラーの両側に位置し、前記左従動ローラー群が圧下前の鋳造スラブをクランプすることに用いられ、前記右従動ローラー群が圧下後の鋳造スラブをクランプすることに用いられ、前記駆動ローラーの直径と従動ローラーの直径との比が１．１：１〜２：１である。 In order to solve the above technical problems, a continuous caster fan segment obtained by applying a high pressure to a continuous cast slab solidifying end according to an embodiment of the present invention is an upper frame, a lower frame, an upper drive roller located in the continuous caster fan segment. A lower drive roller, a left driven roller group, a right driven roller group, a pressure reduction device, and a clamp cylinder, the clamp cylinder being used to clamp the upper frame and the lower frame to maintain a set distance; The drive roller is connected to the pressure reduction device, the upper drive roller is connected to the upper frame through the upper bearing pedestal, and the lower drive roller is connected to the lower frame through the lower bearing pedestal, and the left driven roller group and the above The right driven roller groups are respectively located on both sides of the driving roller, and the left driven roller groups are used for clamping the cast slab before rolling, Right driven roller group is used to clamp the cast slab after rolling, the ratio of the diameters of the driven roller of the drive roller 1.1: 1 to 2: 1.
その内、前記右従動ローラー群と駆動ローラーの開度が圧下後の鋳造スラブ厚さと同じである。 Among them, the opening degree of the right driven roller group and the drive roller is the same as the cast slab thickness after reduction.
その中、前記左従動ローラー群の開度が圧下前の鋳造スラブ厚さと同じである。 Among them, the opening degree of the left driven roller group is the same as the thickness of the cast slab before reduction.
その中、前記駆動ローラーは一体型であり、一体成形プロセスによって製造される。

（３）右従動ローラー群を調整してその開度を上下駆動ローラーの間の間隔と同じにし、圧下後の鋳造スラブをクランプすることに用いられるステップとを含む。
Among them, the drive roller is integral and manufactured by an integral molding process.

The total deformation when high pressure reduction is performed is the total deformation where high pressure reduction deformation is performed on a continuous cast slab by a large roller diameter drive roller, and 5 to 7 pairs of caster rollers of a general fan-shaped segment It is not the total amount of deformation that implements one small deformation to complete the high pressure reduction.

Correspondingly, the required clamping force of the clamping cylinder in the fan segment is reduced, while at the same time the structural material and weight that needs to be increased to maintain the strength and the steelability of the upper and lower fan segments under high pressure reduction. Do;
