Abstract

PURPOSE:To prevent penetration of molten metal into a mating face and formation of metal foil by fastening an upper mold and a lower mold in a graphite mold constituting the mold with tungsten-made fastening bolts. CONSTITUTION:The upper mold 1a and the lower mold 1b at connecting part 1c in the graphite mold 1 buried with refractory material 5 are fastened with the tungsten-made fastening bolts 6. Molten metal is introduced to passage between the upper mold and lower mold and solidified to continuously form a cast billet. In this case, even if the mold becomes high temp. during casting, as heat expansions of the graphite and tungsten are almost same, the fastening force is not weakened. By this method, the entering of molten metal into the mating face between the upper mold and the lower mold and the formation of metal foil can be prevented and the development of flaw at end part of the cast billet can be prevented.

Therefore, during casting the connection (1c) of the graphite mold (1)
There was a problem in that the metal foil was gradually formed at the joints of the ingots, causing defects in the ingot and the molten metal in the molten metal holding furnace flowing out from the defects.6 [Problem to be solved by the invention] The invention was made to solve the above problems, and it prevents molten metal from entering the joints of graphite molds during casting, thereby preventing metal foil from growing at the joints of graphite molds. The purpose is to obtain a continuous casting mold that can prevent the occurrence of ingot defects and melt leakage.

The connection part (lc) tightened with the tightening bolt (6) reaches about 1000°C during casting, but since the difference in linear expansion coefficient between graphite and tungsten is about 6X10-', the temperature of graphite due to thermal expansion increases. The opening of the seam is kept to about 0.02 weight l, preventing the intrusion of molten metal and the formation of metal foil that would cause problems in casting. In the above example,
The tightening bolt (6) is used only at the connection (lc) of the graphite mold (1) inside the refractory material (5), but it is also tightened at the graphite mold (1) in the water-cooled steel jacket (2). You may also use the bolt (6). [Effects of the Invention] As described above, according to the present invention, since the upper and lower molds of the graphite mold constituting the mold are fastened with tungsten tightening bolts, the upper mold and the lower mold are It is possible to prevent the intrusion of molten metal into the seams and the formation of metal foil, thereby preventing the occurrence of flaws at the ends of the ingot.
