Abstract: Pneumatic systems play a crucial role in the manufacturing industry. Many industrial machine require pneumatic systems to operate at present. In industrial machine systems, pneumatic cylinders are one of the machine parts that operate with a high level of intensity; therefore, it is necessary to replace and maintain pneumatic cylinders. The purpose of this paper is to propose the design and production of a prototype pneumatic cylinder that is inexpensive and suitable for single-unit production. The article proposes an approach for determining, developing, and fabricating a pneumatic cylinder prototype for industrial equipment. From the initial working requirements given, a pneumatic cylinder prototype was designed and simulated on Solidwork software. To demonstrate the accuracy of the model, simulations of motion are also taken into account. Next, the dimensions of the pneumatic cylinder are calculated in full detail based on the preliminary model to ensure that they meet the design specifications. The control circuit system is then designed and calculated in accordance with the system's structure. Then, Automation Studio software is utilized to recalculate and validate the model's accuracy. Finally, a pneumatic cylinder prototype was constructed to validate the model. Prototypes are manufactured by CNC machining with the support of CAD/CAM technology. The prototype's smooth motion demonstrates the accuracy of the design process.

Abstract: The large-scale blast furnace ironmaking system, characterized by extremely complicated mechanism, multiphase/field coupling, dynamical working circumstances and unbalanced data set, is facing several problems in information detecting, object modelling, safety manufacturing and operation controlling. How to keep blast furnace in a secure and steady status, i.e., ensuring high efficiency and safety of ironmaking process under various conditions has become a major issue in operational control of industrial system. Many scholars have tried to improve the operation control level of large-scale blast furnace. However, the existing research mainly focuses on individual processes of the blast furnace, lacking studies on intelligent coordinated optimization of the entire ironmaking process, including raw material yard, sintering, and blast furnace operations. In order to help researchers to have a better understanding of the ironmaking process, we have made a comprehensive review of the current developments and future trends in the research of large-scale blast furnace. In this paper, we first introduce the backgrounds and characteristics of ironmaking process, as well as analyze the challenges in different research fields. Then, key technologies and current progress of information perception, feature modelling, fault diagnosis and optimal control in large-scale blast furnace are summarized. Furthermore, the future developments and potential applications of blast furnace ironmaking process are outlined in the end.
