Description

Verfahren zum Stranggießen von Metallblöcken Es, ist ber@ei;ts vorgeschlagen worden, bei@n Gießern von Metallblöcken in Längen, die von der Höhe der Kokille unabhängig sind, unter Einhaltung ei!ne!r konstanten Entfernung zwischen. Gießoberfläche und Gießrinne und unter Absenkung des auf dem Formhoden stehenden erstarrenden Blockes, wähnend des Gießens die Gießgeschwindigkeit so groß und die Gießform so kurz zu halten, daß der am unteren Ende der Gießform .in ein. flüss,ilges Kühlbad austretende Block nur in der Randzone erstarrt ist und nun durch unmittelbare Berührung mit dem flüssigere Kühlmittel völlig zur Erstarrung gebracht wird. Hierbei wird der Formboden mit dem die Kokille verlassenden Blockteil vorzugsweisse, unmittelbar in, ein Wasserbad eingetaucht. Gegebenenfalls ist die Kokille in ihrem oberen Teil beheizt.Process for the continuous casting of metal blocks It has been suggested been, at @ n casters of metal blocks in lengths that correspond to the height of the mold are independent, while maintaining a constant distance between. Casting surface and pouring channel and lowering the solidifying block standing on the testicle, During the casting process, the casting speed is so high and the casting mold closes so short keep that the at the bottom of the mold .in a. liquid cooling bath emerging Block has solidified only in the edge zone and is now in direct contact with the more liquid coolant is completely solidified. Here the Mold bottom with the block part leaving the mold, preferably directly immersed in, a water bath. If necessary, the mold is in its upper part heated.

Es, hat sich herausgestellt, daß bei empfindlichen Legierungen oder bei großen Bllockabmessungen bei dieser scharfen Abschreckung mi;b Wasser gelegentlich Spannungen im Gußblock entstehen, die bis, zu Rissen im Blockinnern, führen können, die, da s-'e bei der Knetverarbeitung sich nilcht verschweißen lassen, zu Ausschuß führen. Es ist nun gefunden: worden., diaß es möglich ist, solche Spannungen; dadurch weitgehend zu vermeiden:, diaß man an Stelle von Wasser andere Flüssigkeiten, verwendest, die, geringere Abschreckwirkung hesiitzen, mit denen; es, aber trotzdem möglich ist, eine im wesentlichen flache Ers.traa.rrungsfrünt und ein Erstarren urmitteilbar außerhalb der Kokille herbeizuführen.It has been found that with sensitive alloys or with large block dimensions with this sharp deterrent with water occasionally Tensions arise in the cast block, which can lead to cracks in the interior of the block, which, since they cannot be welded during kneading, become scrap to lead. It has now been found that it is possible such Tensions; In this way, to a large extent to avoid: one used other instead of water Liquids, which, have a lower deterrent effect, with which; it, but still possible, is an essentially flat replacement and to bring about solidification outside the mold in a manner that can be communicated initially.

:als solche Kühlmittel eignen sich beispielsweise wäßrige kolloidale Lösungen und Emulsionen, wie das aus Apfeltrester gewonnene, im Handel befindliche -Mittel zur Abschreckhärtung, und andere Emulsionen, Wa.sserglaslösungen u. dgl.: aqueous colloidal ones, for example, are suitable as such coolants Solutions and emulsions, such as that obtained from apple pomace, are commercially available -Means for quench hardening, and other emulsions, water glass solutions and the like.

Die Anwendung dieser Kühlmitatiell kann auch lKim Hahlblackgie,ßen und beim Plattiergießen mittels einer kurze». Kalcille vorteilhaft sein, welche Verfahren; Gegen@s;tand weiterer Patenitie s,ihd.The use of this coolant can also be used in Hahlblackgie, ßen and with cladding by means of a short ». Kalcille be beneficial which Procedure; Against further patents, ihd.

PATENTANSPRUCH: Verfahren zum Gießen von Metallblöcken, wobei die Gießgeschwindigkeit so groß und die Gießfarm so kurz ist, daß der am unteren Ende der Giießfo-rm in ein, flüssiges Kühlbad austretende Block nur in der Randzone erstarrt ist und nun durch unmittelbare Berührung mit dem flüssigen Kühlmittel völlig zur Erstarrung gebracht wird, dadurch gekennzeichnet, daß der aue der Gießform austretende Block durch Emu.ls:ionen oder ko-l:loaiidale Lösungen mit geringerer Abschreckwirkung als Wasser abgeschreckt wird.CLAIM OF THE PATENT: Process for casting metal blocks, the The casting speed is so great and the casting farm is so short that the one at the bottom the casting mold emerging into a liquid cooling bath solidifies only in the edge zone and now through direct contact with the liquid coolant completely to Solidification is brought about, characterized in that the outer part of the casting mold emerges Block by Emu.ls: ions or ko-l: loaiidal solutions with less deterrent effect than water is quenched.
