The Setup program takes over and will walk you through the driver installation process.3 You may need to reboot your PC once the driver installation is complete. Enabling SLIIf you have installed multiple graphics cards in your system for SLI, you can set your SLI configuration in the NVIDIA Control Panel:4 In Windows Vista, go to Start > Control Panel > Additional Options and select the NVIDIA Control Panel icon.5 Click on Set SLI and PhysX Configuration in the left task pane and select Enable SLI and click Apply .6 Click Yes on the Applications Shutdown Required window.Note: Quad SLI is only supported under the Windows Vista operating system.SL SPDIF GND213 Remove any existing graphics card(s).4 Install the graphics card into the Primary PCI Express x16 slot.If you are installing an additional GeForce GTX 295 graphics card for Quad SLI configuration, continue with step 5. If you are only installing one GeForce card, go on to step 6.Power Status LEDGREEN: Both power connectors are correctly connectedRED: One or both power connectors are incorrect or not plugged correctlyPrimary Graphics Card LEDIn a Quad SLI configuration running in Quad SLI mode, only one graphics card will have active displays. The blue LED indicates the Primary card with the active displays. Make sure to plug your displays into this card.DVI-I Connectors1. Primary DVI Connector2. Secondary DVI Connector5 For Quad SLI, install the second GeForce card into the outer most PCI Express x16 slot on the motherboard.Connect the two cards together using the dual SLI bridge connector that came with your SLI-ready motherboard.6 Connect BOTH a 6-pin AND an 8-pin PCI Express auxiliary power connector from the computer power supply to the connectors on the top edge of the GeForce GTX 295 graphics card.Attention: If your system has been running for a period of time prior to opening the panels, it is very important that you wait until the graphics cardin yoursystem has cooled before taking the card out of the system. Graphics cards can get hot when they have been operating for any length of time.Note: All of the graphic cards in Quad SLI configuration must be identical.Therefore, both graphics cards must be GeForce GTX 295.Primary PCI Express x16 slotDual SLI Bridge ConnectorHDMI Connector7 If you are going to be using your graphics card to output audio over an HDMI connection, connect the SPDIF cable as shown in the diagram to your primary graphics card:8 Reinstall the cover on your computer and reconnect any cables that you removed earlier in the installation.The GeForce GTX 295 graphics card can be connected to PC monitors or TVs that support DVI, VGA, or HDMI inputs. Supported multi-display configurations vary based on the operating mode of the graphics card that is set in the NVIDIA Control Panel:▪ Multi-display mode: Allows user to output to up to three displays per graphics card. The user can connect to any combination of display outputs on the graphics card.▪ Multi-GPU mode: In this mode, the GPUs work together toincrease rendering performance and image quality. The user can output to up to two displays (only one display supported forWindows XP), but must connect to the displays using the two DVI connectors on the primary graphics card (the primary graphics card is indicated by the blue LED on the bracket).Connect your computer monitor(s) or TV(s) to the GeForce graphics card.Connect this end of the SPDIF cable into the SPDIF header on the motherboard, making sure to match the SPDIF and GND pins on the cable to the correct pins on the motherboard. Consult your motherboard documentation for information on the SPDIF pins on the motherboard.Attention: Make sure to plug the 8-pin PCI Express power connector ( ), NOT the 8-pin motherboard connector ( X ), into your graphics card.Note: When two or more displays are connected, only the one connected to the primary connector of the primary card will POST . The other monitor will not come up until Windows loads.。

HP295性能优化工艺实践
1 概述
焊接气瓶钢板是指厚度为2.5~6.0mm的优质碳素结构铜和低合金结构热轧钢板,焊接气瓶要求具有一定的塑性和强度,加工时先进行一次冷冲压成型,然后利用焊接成型。

液化石油气瓶产品规格为50kg、30kg、15kg、10kg、5kg和2kg级,在钢瓶的总生产量中,家庭型15kg级钢瓶的生产量占98%~99%,15kg级钢瓶年产1500~1600万只,30kg级钢瓶年产20万只。

HP295是一种常用的气瓶用钢,主要用于家用煤气的存储,随着我国石油天然气工业的发展,该产品得到了比较广泛的使用。

济钢焊瓶钢产品自开发之后,一段时间出现产品质量波动大的问题,用户使用过程中出现变形不均、冲压开裂的现象,为此针对产量最大的焊瓶钢――HP295采取了一系列工艺措施,提高焊瓶钢屈强比、延伸率等主要性能指标,满足了用户的使用要求。

2 性能优化措施制定
性能存在的问题主要为屈强比和延伸余量小、屈服强度偏高,因此将性能提升的方向确定为降低屈强比、提高延伸率。

2.1 温度优化
2.1.1 加热温度优化。

板坯经过加热、冷却过程,其中的奥氏体经过再结晶过程,因而组织晶粒尺寸更小,并且分布更为均匀。

加热温度和加热时间工艺参数制定时,既要考虑到节约能源,防止由于过热或加热时间过长导致出现异常组织,又要保证加热充分、组织均匀。

综合考虑组织和成本因素,将出钢温度由1220℃调整为1180℃。

冷料加热最小时间由
140min调整为100min。

2.1.2 终轧温度优化。

终轧温度也是带钢轧制的一个重要工艺参数。

终轧温度越高,带钢内部组织再结晶越充分,分布也更均匀;终轧温度越低,再结晶的部分将增加,同时缺陷组织增多,强度有所降低。

在满足强度要求的前提下,终轧温度适当提高时可提高带钢的击韧性,对降低屈强比也有利。

综合考虑上述因素,将终轧温度由860℃调整为870℃。

2.2 负荷分配优化
精轧负荷分配主要是确定各道次的压下量,在满足个机架轧制力满足轧机能力的前提下,保证轧制稳定和性能要求。

因带钢存在温降,前面机架温度高、变形抗力小,后面机架温度低、变形抗力大,一般负荷分配制定时遵循前大后小的原则。

一般情况下,变形量越大,组织发生再结晶越充分,组织尺寸越小。

为了保证焊瓶钢轧制的稳定性,为了保证精轧压下率、改善屈强比,将中间坯厚度增加1mm,同时对压下负荷分配系数进行了调整,F0~F6负荷分配系数调整为53、45、38、32、20、16、12。

2.3 层流冷却模式优化
屈强比是焊瓶钢一个重要的加工性能指标,国标要求不大于0.8,屈强比数值越小,越有利于加工变形。

HP295各个指标中,屈强比是最难控制的指标,且屈强比余量很小,因此将屈强比作为性能优化的首要原则。

研究实验表明,通过两段冷却能显著降低屈强比,因此焊瓶钢层流冷却均采用两段冷却。

由式(1)和式(2)可以看出,晶粒尺寸对屈服强度的影响要高于对抗拉强度的影响,从这个角度分析,如果要降低HP295的屈强比,可以通
过粗化晶粒尺寸来实现,在宏观上即是要降低屈服强度,把晶粒度控制在合适的范围内,因此,两段冷却模式进一步优化的原则为:在满足屈服和抗拉要求的条件下,适当增大铁素体晶粒度尺寸。

具体实施时,就是减小前段冷却强度,使铁素体在较高温度下经过充分空冷,然后再进行第二次水冷,增大铁素体晶粒尺寸。

通过逐步调整优化,将前段冷却模式由第2组开6优化为第2组开3、第3组开3。

2.4 层流侧喷优化
带钢层流冷却过程是决定产品性能的重要环节,带钢表面残留水对带钢性能的均匀性影响较大,故需要对层流侧喷进行优化,带钢残余冷却水。

层流侧喷的目的是吹扫掉带钢上表面的层流水,使带钢沿宽度方向上的冷却速度尽量均匀。

侧喷的力度取决于带钢表面的水受到的沿带钢宽度方向冲击力的大小,在层流侧喷压力不变的条件下,提高侧喷效果的措施就是设置合理的侧喷参数,使喷出的水都打到带钢上,并且能均匀覆盖整个带钢宽度。

层流侧喷优化的关键为喷嘴在竖直面喷射角,
