A shape detection device capable of detecting meandering of a strip with high accuracy and a method thereof. The device includes a plurality of split rolls provided in a width direction of a rolling material; a table which guides the rolling material and which is rotatably supported; a fixing member supported by the table; torque detectors for separately detecting loads acting on both ends of the split rolls when the rolling material comes in contact with the split roll as moments; supporting arms of which one end rotatably supports the split roll and the other end is supported by the fixing member through the torque detectors; a meandering amount computing unit for computing a meandering amount of the rolling material using the moments detected by the torque detectors, and a plate shape computing unit for computing a plate shape of the rolling material using the moments and the meandering amount.

Shape detection device and shape detection method

A method of producing reduced iron pellets including reducing raw material pellets to obtain reduced iron pellets, and rolling the reduced iron pellets at a temperature ranging between 800 and 1200&#xb0; C. sufficiently such that the reduced iron pellets undergo sintering.

Method of producing reduced iron and production facilities therefor

A method of producing raw material pellets, including forming pellets from a mixture of an iron oxide powder, a coal powder and a binder material after adding adjusting water to the mixture, and drying the pellets, wherein the binder material comprises at least one of tar and at least one of carboxymethylcellulose and polyvinylalcohol.
