  • STEEL SHELL FOR A SUCTION ROLL AND A METHOD OF PRODUCING A STEEL PRODUCT
    Publication number: 20150252529
    Abstract: A suction roll shell having a plurality of through holes is made of a stainless ferrite-austenite steel having a micro-structure essentially consisting of 35-65% by volume of ferrite and 35-65% by volume of austenite. The steel has a composition containing, among other things, 0.005-0.07 C and 0.15-0.30 N, in % by weight.

  • Method and arrangement for monitoring of injector
    Patent number: 8393141
    Abstract: A method is provided for monitoring of the functionality of an After Treatment Injector (ATI) for injection of a fluid in an engine exhaust gas system upstream of an exhaust gas treatment unit. The monitoring is performed by using a pressure sensor which detects the pressure of the fluid delivered to the ATI for a specific condition or injection cycle. The pressure sensor is located downstream of a flow regulator and upstream of the ATI in a conduit for supplying of a substance from a container to the ATI. An ECU is programmed to perform a predetermined sequence of opening and closing commands for the flow regulator and the ATI in order to monitor the functionality of the flow regulator, the ATI and the pressure sensor. The can be used in connection with an On Board Diagnosis (OBD) system.
