Abstract: To change current status of marking process in domestic steel enterprises, facilitate marking equipment localization and enhance enterprise competitiveness, the general design scheme of the online marking system for steel products was put forward by analysing software/hardware and working mode of marking system. Key technologies such as determination of synchronization mode and correlative parameters, driving scheme of high-speed solenoid valve and design for fonts forming software were discussed. And this study provided theoretical foundation and guidance for designing the marking system online. The design result was proved to meet the industrial production demand by experiments.
