Patent DE-4023737-A1 (DE)
Title: Continuously producing seamless tubing - by deforming concasting rod in die fitted with magnetically suspended mandrel
Inventor: WASSEN HANS
IPC: B21C23/08
Filed: 1990-07-26
Abstract: Continuously producing seamless hollow bodies made from metal (alloys) or steel is of passing a continuously cast rod (3) through a die (5) into which a magnetisable mandrel (6) is suspended and held by a magnetic field. At the same time the mandrel is caused to vibrate up and down by an alternating magnetic field. Temp. at the deformation area at the pointed end of the mandrel is pref. kept near to just below the solidus temp. so that the deformation force required is very low. Ratio of concast rod cross-section to hollow block cross-section is pref. greater or equal to 3. Mandrel is held in position by holding magnets (7) and two reversible centering systems (10). Die is protected from over-heating by cooling channels (11). Mandrel has a thermally heat resistant cap (12) which may be produced by build-up welding. Upper end of the mandrel may be made of non-magnetisable material to maximise the working force applied to the concasting. USE/ADVANTAGE - Esp. for mfg. seamless tubing. Tubing can be made in long lengths and in a finished condition which is similar to a rolled or forged condition.
