摘要： PURPOSE:To execute the suitable cooling to high speed casting and to stabilize the casting by injecting a primary cooling water to molten metal cooled with a cooling mold and a secondary cooling water to an initial stage range in generated transition boiling zone and film boiling zone. CONSTITUTION:The molten metal 3 in a tundish 1 is introduced into the cooling mold 2 through an orifice 6 and the surface is cooled to form the solidified shell. The primary cooling is executed by the first cooling water injected from a first injection hole 23 in the cooling mold 2 to progress the solidification. Toward the steam film in the transition boiling zone and the film boiling zone formed on the surface of a cast billet 4 by injecting the primary cooling water, the secondary cooling water is injected from a second injecting hole 24 in the cooling mold 2. The secondary injected cooling water breaks through the transition boiling zone and the film boiling zone, and nucleus boiling is generated, and the cast billet 4 surface is directly secondary-cooled to form the firm solidified shell.

摘要： PURPOSE: To provide an electromagnetic chilling mold which provides an electromagnetic shield more easily and at a lower cost and easier maintenance. CONSTITUTION: This electromagnetic continuous chilling mold 10 has an inductor 18, the electromagnetic shield 24 and a cooling device 12 whose cooling liquid outlet 26 faces to the surface of a bar, and casts the bar, i.e., a billet 32 in the vertical direction. An annular shield 24 is formed with round or elliptic cross section, and in the case the shield 24 forms the elliptic cross section, the major axial diameter d1 is positioned in parallel to the vertical axial line (x) of the bar and the ratio of the major axial diameter d1 to the minor axial diameter d2 is made to 1:1-3:1. The round or elliptic cross section shield can easily be manufactured at a low cost and is hardly plastic-deformed during operating, and even after casting operation over long time, precise correcting work is unnecessary.

摘要： PURPOSE:To stably enable a high speed casting and to improve the productivity by ejecting primary cooling water to a molten steel cooled with a cooling mold, applying the primary cooling and further, applying a secondary cooling with the secondary cooling water. CONSTITUTION:The primary cooling water ejecting hole 23 having 15-40mm the distance from a meniscus and the secondary cooling water ejecting hole 24 having 20-45mm the interval between the contact position of the primary cooling water and the contact position of the secondary cooling water on the ingot (cast billet) are provided. The ejecting angle for the primary cooling water is set to 15-30 deg. and the ejecting angle for the secondary cooling water is set to 30-60 deg.. Solidification is progressed with the primary cooling water from the primary ejecting hole 23 in the cooling mold 2 and successively, the secondary cooling water is ejected toward the steam film in transition boiling zone and film boiling zone generated on the surface of the ingot 4 from the secondary ejecting hole 24. By this method, the nucleus boiling is generated by breaking through the transition boiling zone and the film boiling zone, and the ingot surface is directly secondary-cooled to form the solidified shell having further strength.

摘要： PURPOSE:To obtain the method for producing the polygon mirror having the reflection efficiency having no problems in practicable use at a low cost by using low-impurity aluminum as a material without using high-purity aluminum as the material of the polygon mirror. CONSTITUTION:The low-purity aluminum 1 melted at 700 to 720 deg.C is dropped by gravity through a sprue 2 having an outlet of a polygonal sectional shape and is rapidly cooled by cooling water 3 at the point where the aluminum of the material emerges from the sprue 2, by which the polygonal columnar aluminum blank material 4 having a fine metallic crystal part of 100 to 300mum crystal structure size formed on the rapidly solidified layer of the surface is produced. The polygon mirror is produced by precision closed forging from such polygonal columnar aluminum blank material 4.
