Abstract

FIELD: metallurgy. SUBSTANCE: method involves supplying metal into crystallizer up to metal meniscus through immersion pot; providing radial withdrawal of ingot from immersion pot along cooling zone; forming ingot in crystallizer with parallel wide faces; pressing ingot in secondary cooling zone below crystallizer in solid-liquid and solid states by rollers. During continuous pouring of thin slabs, width of metal meniscus in crystallizer is increased by supplying metal flow from pouring cup at an angle to metal meniscus, with metal meniscus extending along crystallizer length in such a way, that tangent to crystallizer working wall, along small curvature radius at contact points with metal meniscus, is extending at an angle of 45-80 deg to horizontal plane. EFFECT: increased efficiency, simplified method and improved quality of slabs.

Изобретение относится к металлургии, конкретнее к непрерывной разливке тонких слябов. Технический эффект при использовании изобретения заключается в повышении стабильности и производительности процесса непрерывной разливки тонких слябов. Указанный технический эффект достигается тем, что подают металл в кристаллизатор под мениск металла через погружной стакан, вытягивают из него слиток вдоль зоны вторичного охлаждения в радиальном направлении, формируют слиток в кристаллизаторе с параллельными широкими гранями, а также производят обжатие слитка в зоне вторичного охлаждения под кристаллизатором в твердожидком и твердом состоянии при помощи роликов. При непрерывной разливке тонких слябов увеличивают ширину мениска в кристаллизаторе посредством подвода его струи из разливочного стакана под углом к мениску металла, а мениск металла по длине кристаллизатора располагают таким образом, что касательная к рабочей стенке кристаллизатора, расположенной по малому радиусу его кривизны, в точках контакта с мениском металла составляет тот же угол к горизонтали, равный 45 - 80 o. Изобретение предназначено для применения на установках непрерывной разливки металлов.The invention relates to metallurgy, and more particularly to the continuous casting of thin slabs. The technical effect when using the invention is to increase the stability and productivity of the process of continuous casting of thin slabs. The indicated technical effect is achieved by supplying metal to the mold under the meniscus of the metal through an immersion cup, drawing an ingot from it along the secondary cooling zone in the radial direction, forming an ingot in the mold with parallel wide faces, and also compressing the ingot in the secondary cooling zone under the mold in solid-liquid and solid state using rollers. During continuous casting of thin slabs, the meniscus width in the mold is increased by supplying its jet from the casting cup at an angle to the metal meniscus, and the metal meniscus along the mold is positioned so that the tangent to the mold working wall located along its small radius of curvature at the contact points with the meniscus of the metal is the same angle to the horizontal, equal to 45 - 80 o . The invention is intended for use in plants for continuous casting of metals.
