Abstract: Appts. for the prodn. of oxidised iron ore pellets is used for producing reduced iron ore pellets. Appts. consists of (a) a feed for raw pellets; (b) a transport grid for the pellets which conveys the pellets successively through a drying chamber; (c) a dehydration chamber and a preheating chamber (d) a number of electrostatic pptn. units or bag filters for collecting material from the drying chamber and (e) a sintering oven connected to the preheating oven. A reducing atmosphere is maintained in the oven and the temp. is pref. maintained at 1150-1280 degrees C. The pellets pass over collection screens and through a series of cooling devices before final collection. The gas from the oven is fed into the preheating oven and thence to the dehydration oven and thence to the predrying oven. The exhaust is passed through the filters before being discharged to atmosphere. A separate discharge device is used for the reduced pellets which directs the pellets under a water jet to cool them. A double slide is used to separate the reduced pellet discharge from the oxidised pellet discharge and, to ensure that no air gains access to the pellets, N is introduced in the chamber between the two slides. In the reducing mode, an additional feature enables gas to be removed from the preheat oven and fed through one set of filters in which zinc rich material is recovered. Process enables a single installation to be used for the prodn. of either oxidised or reduced iron ore pellets.

Title: Tubular sheet wall thickness regulation system - measures thickness at successive positions in lengthwise direction round periphery
IPC: B29C48/86
Filed: 1990-12-10
Abstract: The system regulates the wall thickness of a tube of sheet material extruded from the annular opening of a head and pulled at adjustable speed by a haulage mechanism. Temperatures in sectors around the head periphery are regulated dependent on wall thicknesses in the respective sectors, and haulage speed dependent on variation in wall thickness from the desired value. At each position on the periphery, thickness is measured at several successive points in the lengthwise direction of the sheet, and from the results a mean value is calculated. From these in turn a mean value is calculated for the entire periphery, and the discrepancies from this value of the individual sectors are used to generate control signals altering their respective temperatures.
