Fluent热轧钢卷显热回收利用技术模拟研究
热轧钢卷显热回收技术，是针对热轧刚结束的钢卷进行余热回收。该技术可以吸收钢卷从650℃降温至350℃的过程中所释放出的热量。该热量通过将水冷壁管内的水加热蒸发，变为蒸汽后，将蒸汽进行收集用作它用，比如转化为动能。最重要的是使得生产过程中所产生的能量得到了最大程度的利用，有效节约了能源。可以说，该项技术的发展前景相当可观。
本设计主要分为实物测量和软件模拟两块部分。软件模拟是使用Airpak或者Gambit进行建模。设计主要采用Gambit建模，再通过Fluent进行非稳态传热计算，通过对蒸发总量的计算，从而判断该研究的可行性和实用性。31103

Hot Rolled Steel Coils Sensible Heat Recycling Technology Simulation Study
Abstract: With the increasing of China's steel production capacity, total demand for energy will have corresponding growth. Through the energy saving technical reconstruction or waste heat recovery, and reducing the energy consumption of the iron and steel enterprises is the inevitable choice of easing the energy constraint.
Hot rolled steel coils sensible heat recovery technology is just after the hot rolled steel coils for waste heat recovery. The technology can absorb the temperature of coil from 650 ℃ to 350 ℃ in the process of heat release. The heat heats water in the water wall tube, makes water become water vapor, then recycling water vapor to convert it into other forms of energy, such as the kinetic energy. The most important thing is to make the production process of energy to get the best use, it effectively save the energy. It can also say, the technology development prospect is considerable.
This design is mainly pided into a physical measurement and software simulation. Software simulation can use Airpak, Gambit to make a model. This design mainly uses the Gambit. Next Fluent make a calculation by using unsteady heat transfer. Finally it records the evaporation quantity of water, so as to determine the feasibility and practicability of the study.
Keywords: Energy saving reconstruction; Waste heat recovery; Gambit; Unsteady heat transfer calculation
