Patent CA-2261501-C (CA)
Inventor: JANZ JOACHIM
IPC: C21B5/02
Filed: 1999-02-12
Granted: 2003-11-18
Abstract: The invention concerns a process and en apparatus for producing metal from metal ores, in particular crude or pig iron from iron ore, in which the ore which contains metal oxides is brought into reaction contact with a reducing gas which contains carbon and/or hydrogen (and possibly compounds thereof) and which was previously obtained from solid, carbon-bearing and/or hydrocarbon-bearing substances, It is known that the ore which for the major part comprises metal oxides (being various ones, even in the case of iron) must be subjected to a reduction procedure before the metal can be obtained. Taking the known process as set forth in the opening part of this specification as its basic starting point, the object of the invention is to make plastic waste, including in organically and/or inorganically contaminated form, useable as a supplier for the constituents of the reducing gas. Plastic waste occurs constantly in large amounts and represents a serious disposal problem. It occurs mostly if not exclusively in solid form, either as packaging waste -which is frequently heavily contaminated -, or as offcuts or the like in the course of the production of plastic articles. Accordingly the invention provides that the carbon-bearing and/or hydrocarbon-bearing substances, at least partially comprising plastic material, which in the process of the general kind set forth in the opening part of this specification are supplied to obtain the reducing gas, are injected in comminuted fluidised form as an agglomerate into the air flow in the hearth of the metallurgical shaft or pit furnace, in particular a blast furnace. That is effected by way of lances which project into the shaft furnace and which are connected to a transport conduit. The plastic material to be injected is fed to the lances by way of that transport conduit. In the event that, contrary to expectation, blockages should occur or hot air should blow back out of the blast furnace into the lance and thus into the transport conduit, a plurality of shut-off or check devices are proposed in the transport conduit, so that the transport conduit is not only protected but immediate resumption of overall operation of the installation and injection of the plastic materials occurs. To dissolve blockages of the plastic material in the transport conduit, there are provided a first and third shut-off device, while a second shut-off device is provided to prevent reverse transportation of plastic material or blow-back of the hot gas masses from the blast furnace into the transport conduit. The mode of operation thereof is set forth in greater detail in the claims but in particular also in the specific description.

Title: Method and apparatus for die jam protection/anticipation and correction
Inventor: LUKAS DANIEL G
IPC: B21C51/00
Filed: 1998-03-04
Granted: 2000-06-13
Abstract: A method and apparatus for protecting a die (1) from damage due to material jams in the material stamping equipment, wherein the material is advanced through the die by press feed rollers (6) powered by a drive motor (5). The position error, of the rollers (6) is monitored by the resolver (11), and the torque, of the drive motor (5) is monitored by a strain gauge (10), during the advance of the material through the die. The monitored position error or torque of the motor (5) is compared to the expected position error or the expected torque. If the monitored position error or torque deviates by more than a tolerance value from the expected position error or torque then the material is moved backwards to a previous position, typically the position at which the material was last stamped. The operation of the material stamping equipment may be stopped after the material is moved back if desired.
