INVENTORS WILLIAM A. WOOD CA-MILLE A. ZELDIN 2a vz 'ad ATTORNEYS United States Patent 3,342,252 M ANDREL FOR CONTINUOUS CASTING MOLD William A. Wood, Glen Burnie, and Camille A. Zeldin,
Baltimore, Md., assignors to Kennecott Copper Corporation, New York, N.Y., a corporation of New York Filed Sept. 15, 1964, Ser. No. 396,687 2 Claims. (Cl. 164-283) This invention relates to apparatus for the continuous casting of metal, such as copper, brass or aluminum and has for its object the provision of an improved mandrel for use in a mold to cast hollow billets or tubes.
Apparatus for continuously casting hollow billets usually comprises a mold having an inner lining of graphite, a graphite mandrel suspended in the mold forming an annular upright space in which the metal is poured and solidified, means, for lubricating the graphite surfaces and means for cooling and vibrating the mold and drawing the cooled billet out of the mold. The mandrel of the invention is used in a casting apparatus of this type.
The improved mandrel of the invention is formed of graphite, and is constructed to be suspended in the graphite mold so as to provide the space for pouring the metal and forming the hollow billet. The mandrels used for continuou casting are largely surrounded with molten metal and usually are heated to temperatures approximating the temperature of the metal. At such temperatures the graphite is subject to corrosion and breakage. Accordingly the mandrels used heretofore have relatively short life and are the cause of delaying inetrruptions. The cooling and lubricating of the mandrel have not been satisfactory heretofore and have not contributed to a solution of the problem of extending the useful life of mandrels used in hollow billet casting.
The graphite mandrel of the invention is hollow and is provided with means in the hollow space for cooling and/ or lubricating the mandrel. The mandrel is preferably fitted with a cooling means, preferably a tubular coil for circulating a cooling fluid inside the mandrel, and means for supporting the coil in heat-exchange contact with the mandrel. In one of its aspects the mandrel includes a means for introducing and distributing a lubricant in the mandrel. The invention preferably provides a core inserted into the mandrel for the distribution therein of a lubricant which is dispersed through pores in the graphite to the casting surface. Advantageously the invention includes a combination of the cooling means and the core for distributing lubricant. The tubular coil is constructed to make a close fit in the mandrel to add strength or reinforcement to the mandrel and to absorb the heat to protect the mandrel and facilitate the solidification of the metal.
In the accompanying drawings FIG. 1 is a fragmentary side elevation, with parts in section, of billet casting apparatus illustrating the use of the improved mandrel of the invention;
FIG. 2 is a side view, partly in section, illustrating the mandrel of FIG. 1 having a lubricant distributor core;
FIG. 3 is a sectional side view of the mandrel provided with a coolant coil, and
FIG. 4 is a side view, with parts in section, of a mandrel of the invention having both a coolant coil and a core for the distribution of a lubricant.
The apparatus of FIG. 1 comprises a metal mold support 1, circular in cross-section, a graphite mold or liner 2, a graphite mandrel M, coupling ring 3, preferably formed in two parts and bolted in snug contact with the mold support 1. The support 1 and the mold 2 are preferably provided with cooling means and the mold 2 with lubricating means. The mandrel support 4 may be circular in plan, has an annular groove 5 which centers it on the mold support 1, bolts 6 for securing it to the coupling 3,342,252 Patented Sept. 19', 1967 ring 3 and an annular recess 7 for receiving the annular the mandrel in place.
The graphite mandrel M illustrated comprises two main parts the upper head part 9 and the lower tapered part 12. The mandrel head has a cylindrical recess or cup 13 at the top for receiving molten metal and three radially disposed ducts D through which metal flows into the casting space.
The mandrel M shown in FIG. 2 is preferably constructed by machining and boring a single piece of graphite to form the head portion 9 including the cup 13 which is the subject of the copending application of William H. Ludwig, Ser. No. 398,844, filed Sept. 24, 1964. The lower inner portion 12 of the mandrel, from the surface 14 to the bottom end 15 is hollow, advantageously having a cylindrical inner surface 16 and the outer surface 17 from about the surface 14 downward is tapered downward to compensate for the shrinkage of the solidified billet. This portion of the mandrel which is tapered and a short section thereabove is normally contacted with the metal of the billet. FIG. 1 shows the liquid metal L surrounding the head and the solidified billet therebelow. It is important to lubricate both the mold and the mandrel and this may be achieved by forcing a suitable gas through pores or small holes in the graphite. The mandrel of the invention includes effective means for introducing and distributing a fluid lubricant in the mandrel. The interior hollow space within surface 16 has a snug fitting, generally cylindrical, core 18 which has a helical groove 19 providing channels facing the inside surface 16. The uppermost end of the helical groove is connected to an upright duct such as a bore hole 20 which connects to a tube 21 for introducing a lubricant gas through the groove and into contact with the mandrel inner surface 16. The core 18 is held in position within the mandrel by the graphite screw plug 22. The core not only serves as a lubricant distributor but a reinforcement for the fragile hollow mandrel.
FIG. 3 illustrates a hollow graphite mandrel M similar to the mandrel of FIG. 2 having a hollow center in which is mounted a coiled metal tube 25 which is in direct contact with the inner wall surface 16. This tube is preferably of good heat conducting metal such as copper and is in heat-exchange contact with the mandrel. The inlet end 26 of the tube passes upwardly through hole 27 and the outlet end 28 passes up through hole 29. It will be noted that the incoming coolant fluid, preferably refrigerated gas, enters the coil near the top where the mandrel is hottest and leaves the mandrel at the bottom where the mandrel is the coolest. The graphite plug 30 secures the coil in position.
FIG. 4 illustrates a graphite mandrel M as shown in FIGS. 2 and 3 having a hollow center within the surface 16 in which a tubular coolant coil 25 is mounted as in FIG. 3. The space within the coil has a snug-fitting core 18 as shown in FIG. 2. The mandrel of FIG. 4 provides the cooling coil of FIG. 3 in combination with the core and groove means of FIG. 2 for the introduction and distribution of a lubricant.
The mandrel support shown in FIG. 1 is the subject of the copending patent application of George C. Earl, Ir.,
Ser. No. 395,541, filed Sept. 10, 1964.
