在南美洲的一座钢厂里，美国红阀公司A型夹管阀已经成功地通过测试并成功地应用在连续铸钢工艺中的细粒生石灰控制过程中。这些生石灰是用来将氧混合在熔化的钢水中。钙颗粒与钢水中的杂质化合后在炼钢炉内形成一层表面炉渣。这就是采用HYL：Davy McKee工艺的铁矿的首次破碎。 A Steel Mill in South America has successfully tested, and uses, Red Valve Type A Pinch Valves on dry Calcium Oxide in fine grain size on their continuous casting steel process. The Calcium Oxide is used to mix oxygen with the molten steel. The Calcium particles combine with impurities in the steel to produce surface slag in the blast furnace. This is the primary reduction of Iron Ore using the HYL: Davy McKee process. 这个工艺最终能从混杂着铁屑的铁丸中炼制出钢来。在熔化期间，杂质（与生石灰化合）会形成一层炉渣表面，很容易分离清除。 This process ultimately produces steel from iron pellets mixed with scrap iron. When melted, the impurities (combined with the Calcium Oxide), form a surface slag to ease their removal. 在本页图中，3号阀门原先采用的是蝶阀，后来改为采用美国红阀公司的A型夹管阀。蝶阀对生石灰颗粒流体具有一定的堵塞作用，延长了排放时间。而且，由于生石灰颗粒的研磨作用导致蝶阀磨损严重，因此采用蝶阀时如何维护保养成为一个难题。 In the drawing on this page, valve number 3 was butterfly valve and was replaced by a Type A Valve. The butterfly valve obstructed the gravity flow of the fine mesh Calcium Oxide grains which increased the discharge time, and also became a maintenance problem due to abrasion from the grains. 阀门（A）是一个A型夹管阀，用在气动输送传送线上，为几个贮料筒仓输送流体物质。阀门（B）也是一个A型夹管阀，对主贮料筒仓施加6公斤的进口压力（温度为90摄氏度）。这些夹管阀代替了通径为DN100的蝶阀，因为那些蝶阀每三个月就要修理一次。 Valve (A) is a Type A Pinch Valve applied on a main pneumatic conveyance transmission line feeding to several storage silos. Valve (B) is a Type A Pinch Valve applied on the main silo inlet pressure of application 6Kg/Cm2 at 90 degrees C. These valves replace 4" Butterfly valves that were being repaired every three months. 美国红阀公司的A型夹管阀在这种应用场合的使用寿命至少是12~24个月，每天操作频率为10~20次。 The Red Valve Type A Valves have a service life in this application of at least 12-24 months, being cycled 10-20 times per day. 阀门（C）作为贮料筒仓的出口控制装置，用来控制生石灰在重力作用下排放到炼钢炉中。这个阀门每六小时就要循环操作一遍，要求在三分钟内清空贮料筒仓（B）。以前，在这个位置的蝶阀在其阀瓣旋转过程中会产生流体流动不顺畅的问题。蝶阀阀瓣会使上游的生石灰积压而堵塞贮料筒仓的出口，使得蝶阀开启时生石灰流体不能立即开始流动，而在这个时候上，时间是个最需要关注的问题。 Valve (C) is being used as a tank outlet control of dry Calcium Oxide in gravity feed discharge to the blast furnace and is cycled one time every six hours to empty silo (B) in three minutes. Formerly, the butterfly valve in this location caused flow problems during it's rotation. The vane caused Calcium Oxide upstream to compress and then plug the outlet such that the flow would not begin immediately, and time is critical at this point of the cycle. 阀门（D）是一个系列D刀闸阀，起着关断的作用。每个贮料筒仓一般需要六个A型夹管阀，一个系列D泥浆刀闸阀和三个系列75手动夹管阀。 Valve (D) is a Series D Knife gate Valve for isolation purposes only. Each silo has the potential to use six Type A Valves, one Series D Slurry Knife Gate and three Series 75 Manual Pinch Valves. 在这个连续铸造炼钢厂里一共有八个贮料筒仓，都采用类似的工艺流程，因此都从美国红阀公司的产品中获益。 There are eight silos in this continuous casting Steel Mill. There are many other continuous casting mills that use a similar process and can benefit from the use Red Valve products similarly. |
