Description
Известны способы охлал дени верха стального слитка, применение которых не обеспечивает снижение головной обрези ниже 13-25% от iBeca слитка.Known methods chilled the top of a steel ingot, the use of which does not reduce head trim below 13-25% of iBeca ingot.
Предлагаемый способ обеспечивает значительное снижение обрези слитка {до 4-7% от его веса) и отличаетс от известных тем что разливку стали осуществл ют в изложницу бутылочной формы, имеющую сверху теплоизол ционную надставку.The proposed method provides a significant reduction in ingot trimming (up to 4-7% of its weight) and differs from the known ones in that the steel is cast into a mold in a bottle form having a thermal insulative extension on top.
На чертеже показана изложница бутылочной формы дл осуществлени предлагаемого способа.The drawing shows the mold of the bottle for the implementation of the proposed method.
Жидкий металл заливают в изложницу 7 с утепл ющей футерованной надставкой 2. При затвердевании стали в вepxнeй.узкой части изложницы (в горловине) металл затвердеет быстрее, чем в надставке и изложнице. Благодар этому здесь образуетс мост твердого .плотного металла. Оставщийс жидкий металл в надставке над мостом затвердевает , надежно изолиру от атмосферы открытую усадочную раковину 3, котора будет образовыватьс под мостом.The liquid metal is poured into the mold 7 with insulated lining extension 2. When the steel hardens in the upper part of the mold (in the throat), the metal hardens faster than in the extension and the mold. Due to this, a solid solid metal bridge is formed here. The remaining liquid metal in the extension above the bridge hardens, reliably isolating the open shrinkage shell 3 from the atmosphere, which will form under the bridge.
Ликваци элементов в таком слитке 4 незначительна Закрыта усадочна раковина 5 оказываетс чистой и при обработке давлением свариваетс . Открыта усадочна раковина всегда окисл етс F прч обработке давлением не свариваетс и поэтому отводитс в обрезь Выход годного металла от таких слитков значительно выще чем при Других способах отливки.The elimination of the elements in such an ingot 4 is negligible. The closed shrinkage shell 5 is clean and is welded during pressure treatment. An open shrinkage shell is always oxidized by FH. The pressure treatment does not weld and therefore is cut off. The yield of metal from such ingots is much higher than with other casting methods.
Предмет изобретени Subject invention
Способ охлаждени верха стального слитка, отличающийс тем, что, с целью уменьщени отходов при обрезке слитка разчивку стали осуществл ют в изложницу бутылочной формы, имеющую свепху теплоизол ционную надставку.A method of cooling the top of a steel ingot, characterized in that, in order to reduce waste during the cutting of an ingot, the steel is cast into a bottle mold having a super heat insulating extension into the mold.
