Jablonski said. “It comes down to this: when you build a new [sand processing] plant, you can’t build just for today. Eventually, all industries have down cycles.”
The Metalcaster’s Recourse So what are metalcasters to do as the casting sand sup-
ply constricts? Industry experts point to two options—use different sand or use less sand. “[Metalcasters] can look at using what I would call less than ideal sands,” Jablonski said. “Tere are a lot of other sands that can be used—lake sands, bank sands, etc. Tey are not as round, so you might have to change your processes to use them.” Peaslee said his company would use a multi-pronged
approach to combatting a sand shortage. First, it would explore the possibility of adjusting processes to meet the requirements of a new material. Second, it would rely on good old fashioned manners. “Getting the material has never been an issue for
us because we have been loyal to our suppliers. We don’t go shopping,” he said. “If a shortage did occur, we would keep our eyes or ears open for alternative sup- pliers, but we would also like to stay with suppliers and build a relationship.” Jablonski suggests metalcasters look closer at sand
reclamation in their facilities to keep sands from becoming spent as quickly. “If you called today and asked us for sand supply, we
would need to know your volume requirements,” he said. “From the foundry standpoint, we are at capacity. What this should do in my mind is [make metalcasters] think more actively about reclamation.” Jablonski said he has a number of customers that are
他们吸干地球吗？
“在这一点上砂矿不是一个真正的问题，” Jablon- ski说。“总的来说：当你建立一个新的砂工厂，你不仅 仅是为今天使用而建造的。 最后，所有行业都有萧条的 时候。“
铸造厂的追索权 那么，当铸造用砂供给缩紧后，铸造厂又能做些什 么那？
业内专家指出两种选择--使用其它的砂或者尽可能少 得使用砂子。
“铸造厂可以考虑使用我所说的不够理想的砂子，”
Jablonski说。“有很多其它的砂子可以用，如选择使 用—湖砂、岸砂等，它们不够圆整，所以你可能需要改 变工艺来使用这些砂子。“ Peasle表示他的公司将从多方面入手解决砂短缺问 题。首先，它将探索调整工艺的可行性，以满足新材料 的要求。 其次，公司将依靠良好的传统方式。 “对于我们来说，原材料的获取从来就不是一个问 题，因为我们与供应商关系一直很好。
我们不是普通的买东西，”他说。“如果确实发生短 缺，我们将全身心寻找替代供应商，但是，我们也要与 供应商保持联系并建立合作关系。 “ Jablonski建议铸造厂们仔细研究看看旧砂再生，以 避免砂很快地被用掉 。
“如果你今天打电话要求我们供应砂，我们需要知道
Silica sand can come from a variety of sources, including river beds (shown). Until recently the hydraulic fracturing industry used different grades of sand than metalcasting facilities.
石英砂可以有各种来源，包括河床（如图所示）。 直到最近， 相比于铸造厂水力压裂行业才使用多等级的砂子。
