摘要： A casting of metal strip by continuous casting in a twin roll caster is provied. In a twin roll caster, molten metal is introduced between a pair of counter-rotated horizontal casting rolls that are cooled so that metal shells solidify on the moving roll surfaces. The twin roll caster is capable of continuously producing cast strip from molten steel through a sequence of ladles positioned on a turret. In casting thin strip by twin roll caster, the crown of the casting surfaces of the casting rolls varies during a casting campaign. The crown of the casting surfaces of the casting rolls in turn determines the strip thickness profile.
摘要翻译：本发明涉及在双辊连铸机中通过连续铸造金属带。在双辊连铸机中，将熔融金属引入一对反向旋转的水平铸辊之间，所述水平铸辊被冷却，使得金属壳在移动的辊表面上凝固。双辊铸机能够通过位于炮塔上的一系列钢包连续生产钢水铸造钢带。在用双辊铸机铸造薄带时，在铸造过程中，铸辊铸件表面的顶部会发生变化。铸辊的铸造表面的顶部又决定了带材厚度分布。公开了一种可靠而有效的方法，用于在铸造过程中直接并且严密地控制铸辊铸造表面中的冠部形状，并进而控制由双辊铸造机生产的薄铸造带材的横截面厚度分布。本发明公开了一种控制横截面带钢厚度轮廓的方法，该方法通过位于形成铸辊的圆柱形管内和附近的膨胀环来控制铸造表面中的顶部。

摘要： Provided is a spray nozzle configured so that the angle of spray does not change even if the flow rate of liquid is adjusted largely. A circular conical primary hole narrowing toward the discharge-side front end is provided in a communicating manner at the discharge-side center of a primary flow passage extending along the center axis of a nozzle body, and a pair of secondary holes is provided on both sides of the primary hole in the width direction so as to communicate with the primary flow passage and the primary hole. The secondary holes are formed in an elongated shape, and portions of the long sides of the secondary holes on both sides, the portions facing each other across the primary hole, and both side portions of the primary hole are connected. The ratio of the length (D2) of the secondary holes to the rear end diameter (D1) of the primary hole, that is, D1: D2, is set in the range of 1:0.7 to 1:1.2. A cutout is formed in the discharge-side end surface of the nozzle body so as to extend in the diameter direction which is the same direction as the length direction of the secondary holes, and forming the cutout removes the front end circular arc section of the primary hole to form a discharge opening.

摘要： A method of casting a metal ingot with a microstructure that facilitates further working, such as hot and cold rolling. The metal is cast in a direct chill casting mold, or the equivalent, that directs a spray of coolant liquid onto the outer surface of the ingot to achieve rapid cooling. The coolant is removed from the surface at a location where the emerging embryonic ingot is still not completely solid, such that the latent heat of solidification and the sensible heat of the molten core raises the temperature of the adjacent solid shell to a convergence temperature that is above a transition temperature for in-situ homogenization of the metal. A further conventional homogenization step is then not required. The invention also relates to the heat -treatment of such ingots prior to hot working.

A continuous casting mold 1 according to the present invention has plural separate portions 3 filled with a metal of low thermal conductivity formed by filling a metal having a thermal conductivity of 30% or less of that of copper into circular concave grooves 2 having a diameter of 2 to 20 mm which are formed in the region of the inner wall surface of the copper mold from an arbitrary position higher than a meniscus to a position 20 mm or more lower than the meniscus, in which the filling thickness (H) of the metal in the portions filled with the metal of low thermal conductivity is equal to or less than the depth of the circular concave grooves and satisfies the relationship with the diameter (d) of the portions filled with the metal of low thermal conductivity expressed by expression (1) below: 0.5 ≤ H ≤ d
