Description
【０００１】0001
本考案は溶融金属などの流動や不純物の挙動をシミュレーションするための 水モデル実験用トレーサ粒子に関するものである。 This invention is a method for simulating the flow of molten metal and the behavior of impurities. It concerns tracer particles for water model experiments.
【０００２】0002
溶融した金属の流動状況を知ることは、精錬機能の追求には欠かすことのでき ない情報となってきている。このため、液体の動粘性が溶鋼などとほぼ等しく、 取扱いの容易な水を用いて、各種のシミュレーション実験を行っている。 この際に、溶融金属の流動や、溶融金属中の非金属介在物の挙動を明瞭にする ため、各種のトレーサを工夫している。トレーサには、ポリスチレン粒子やステ アリン酸の粒子を用いることが多い。これは、実機と水モデルとでフルード数な どの流体力学的相似条件を満足するために、その粒子の比重，粒径が重要となる ためである。 Knowing the flow conditions of molten metal is essential for pursuing refining functions. There is no information available. Therefore, the kinematic viscosity of the liquid is almost the same as that of molten steel, etc. We are conducting various simulation experiments using water, which is easy to handle. At this time, clarify the flow of molten metal and the behavior of nonmetallic inclusions in molten metal. Therefore, we are devising various tracers. Tracers include polystyrene particles and Particles of alic acid are often used. This is the Froude number between the actual machine and the water model. In order to satisfy which hydrodynamic similarity condition, the specific gravity and particle size of the particle are important. It's for a reason.
【０００３】 特に、溶鋼中の微細介在物の挙動や流動状態をシミュレーションするためには 、ステアリン酸などの白色の粒子を用いることがあるが、水と光学的な反射率が 近いために、トレーサとして見にくくなるという欠点があった。 また、水モデル実験に用いるトレーサ粒子は、多量に用いるものではないので 、どうしても既製品を用いることになり、適当な比重，粒径のもので、見やすい ものがなかった。0003 In particular, in order to simulate the behavior and flow state of fine inclusions in molten steel. , white particles such as stearic acid are sometimes used, but the optical reflectance of water and Because they are so close together, they have the disadvantage that they are difficult to see as tracers. In addition, tracer particles used in water model experiments are not used in large quantities; , it is inevitable to use a ready-made product, and it is one with appropriate specific gravity and particle size that is easy to see. There was nothing.
【０００４】 また、見やすいトレーサ粒子として蛍光物質でできたものがあるが、これは蛍 光物質によって比重が決まるため任意に比重を選択できないという欠点があった 。0004 In addition, some easy-to-see tracer particles are made of fluorescent materials; The drawback was that the specific gravity could not be selected arbitrarily because the specific gravity was determined by the optical substance. .

Provides easy-to-see, inexpensive, and effective tracer particles for water model experiments. The purpose is to

Good too. In addition, the particle size is determined by the hydrodynamic similarity conditions for water model experiments. It is sufficient to use one with a diameter of .

本考案によるトレーサ粒子を用いることにより水中で見分け難かった白色粒子 やアルミ粉末などを発色させることができる。また、紫外線を含んだ蛍光燈、た とえばブラックライトなどを水モデル装置に当てることにより、トレーサ粒子の みを発光させることが出来るようになった。この結果、溶融金属の流動や非金属 介在物の流動を明瞭にシミュレーションすることができる。 White particles that were difficult to distinguish in water by using the tracer particles of this invention It can color aluminum powder, aluminum powder, etc. Also, avoid using fluorescent lights that contain ultraviolet light, For example, by shining a black light on a water model device, tracer particles can be detected. It is now possible to make light emit light. As a result, the flow of molten metal and non-metal The flow of inclusions can be clearly simulated.
