This invention relates to a method of rolling steel rails comprising : a method of rolling steel rails comprising: providing a rail blank (5), the blank comprising a foot portion (2), a head portion (3) and a web portion (4) connecting the foot portion to the head portion; finishing the rail blank to form a steel rail (6) in a multi-stand continuous tandem finishing mill comprising at least one horizontal stand (H) and at least five four-roll universal stands (U), wherein each universal stand (U x ) only contains flat vertical rolls for forming the lower foot portion (2a) and the head portion (3a) of the rail, and wherein each universal stand (U x ) contains two shaped horizontal rolls for forming the sides (6a, 6b) of the rail and particularly the web portion (4a, 4b) of the rail, wherein the rail blank is passed only once through said finishing mill, and wherein in at least one combination of two subsequent stands U l and U l+1 ⋅ the rail is worked on the foot and not on the head using the flat vertical rolls in U l and wherein the rail is worked on the head and not on the foot using the flat vertical rolls in U l+1 ; or ⋅ the rail is worked on the head and not on the foot using the flat vertical rolls in U l and wherein the rail is worked on the foot and not on the head using the flat vertical rolls in U l+1 . The invention also relates to an apparatus for carrying out said method, and to a product produced therewith.
摘要:
The invention relates to a method and a device for assessing through-wall leakage and combustion problems of a heating wall of a coke oven (20) by measuring gas components and dust of combustion waste gases exiting the heating walls (Wall 20, Wall 21) of the coke oven, wherein components of combustion waste gases are measured simultaneously from both heating walls of a coke oven. The device for measuring the components of the waste gases is a self contained unit with measuring devices in a temperature regulated closable housing.

A method of manufacturing working electrodes for series connected dye sensitised solar cells in a continuous reel-to-reel production line comprising the steps of: i. Providing a metal carrier strip substrate having a first side and a second side; ii. Providing an organic electrically insulating layer on the first side of the metal carrier substrate having a temperature resistance in the range of 200°C to 600°C; iii. Providing an organic conductive layer on the electrically insulating layer having a temperature resistance in the range of 200°C to 600°C, optionally comprising conductive inorganic additives; iv. Scribing the organic conductive layer at regular intervals to divide the organic conductive layer into cells that are electrically separated; v. Providing a metal oxide layer on the scribed organic conductive layer; vi. Sintering the metal oxide layer; vii. Sensitising the sintered metal oxide layer with a dye.
