Due to the pure and stable composition, direct reduction iron (DRI) is considered to be the perfect material for electric arc furnace (EAF) steelmaking. [1] As EAF steel output growing and the high quality scrap supply is seriously insufficient, the demand for DRI will grow continuously in the world.

With the development of energy science and technology, thermal system becomes more complicated and higher parameterization.
That might affect the closing of valves and cause damage. 7) Mechanical parts and pipe wear may affect the system runs normally 8) It is possible that corroded components in thermodynamic system maybe undergo chemical reaction with some certain fluids catalyzed by certain material 9) Several different kinds of fluid flowed over the same pipe may occur fluid mixed and happen some chemical reactions in some cases. 10) Scrap emitted from pipes may feedback into other pipelines 11) Each branch of various loops may not prevent sneak backflow 12) If valves in a system can realize different functions when they are in different operating mode, valves at the process of closing will produce unexpected actions. 13) Different operating mode has different pressure level, it may exceed predetermined range in some cases. 14) Each valve of system opens in the wrong order. 15) Multiple valves when they are opened or closed at the same time may cause undesirable effect. 16) The opening status of

The present paper, summarizing studies carried out within last years at the Research Center of Mechanics of Materials and Structural Reliability-CEMSIG ([5-8]), from the Department of Steel Structures and Structural Mechanics, is intended to provide some new evidence on the previous FEMA 277 conclusions.
The material in members and connections is S355 structural steel.
For the full-scale AEM models, same properties were adopted (meshing, material properties, acceptance criteria).

Because Granier probe to the variation of the temperature is anomaly sensitive, the probes were external packaged radiation material to reduce the thermal radiation to probe the interference, at the same time it can prevent rain immersion effect to guarantee the determination results from the influence of a certain extent.
