A conversation with 哈伯德大厅’s Jerry Dwyer
Jerry Dwyer CEF, is 哈伯德大厅’s market manager for product groups pertaining to heat treating, black oxide and phosphates. 他的背景和经验使他对热处理和金属精加工领域有着渊博的见解. 德怀尔专门从事上述工艺，在热处理和金属精加工行业有30多年的历史. Dwyer has a Bachelor’s degree in chemistry and biology.
We recently caught up with him to ask a few questions about the heat treat market, and what trends he sees ahead for manufacturers using these applications.

问:你能告诉我们一些你的背景和你是如何进入热处理市场的吗?
JD:在我30多年的职业生涯中，我一直服务于热处理和金属精加工市场. 我一直站在供应方，为客户的业务提供化学物质. Hubbard-Hall has both high heat and quench products for captive and job shop needs; our quench salts, 油, and polymers are well known in the industry.
Q: Tell us what heat treating metals is all about?
JD: There are many different aspects to the heat treating space, 简而言之:将金属加工成所需的形状或状态，然后对其进行热处理，以实现其实际应用或预期用途.
问:你提到你的客户购买淬火油、淬火盐和聚合物
Hubbard-Hall. Why would they select one quench medium over the others?
JD:这完全取决于正在加工的东西和被热处理的物品的最终用途. For instance, quench salts are primarily used in an austempering process. 盐非常适合等温回火，因为它有理想的工作温度范围, to where banite is ultimately formed during the quench process. The end result will impart good hardness to the work along with a desired ductility. 当需要更高的硬度而牺牲一些延展性特性时，使用淬火油和聚合物. Parts are quenched in oil at a lower operating temperature than salt, resulting in a more severe quench and achieving martensite as a result.
问:你能给我们举几个例子，哪些部件是用盐处理的，而不是用淬火油或聚合物处理的吗?
JD: Typical parts that would be heat treated in a salt process would include springs, automotive clips, lawnmower blades, tools such as hex keys and torque wrenches, and the list goes on. 任何部分，将需要一些“给予”下的扭矩或张力，但需要良好的硬度.
问:与其他淬火介质相比，使用盐有什么缺点吗?
JD:最常见的问题是当顾客得到这种包装的盐时，袋子的重量. I’m always asked if the bags can be reduced in weight from their current 50 pounds; customers ask for smaller and lighter bags due to worker complaints and for liability reasons, 也. A skid of bags will weigh 2,000 pounds containing 40 bags; larger customers will sometime go through a truckload or more a month of salt. 现在许多客户都选择了我们标准的500磅的桶来代替提包. 有鼓式料斗和螺旋进料系统，使生活更容易时，转移盐到坦克. Reducing the weight of the 50-pound bag only results in more frequent handling. 此外，带着一个50磅重的袋子接近一个热的熔盐罐也不是一项理想的任务. 我们在澳门威尼斯人网上赌场学院就这个袋子的问题进行了讨论，得出了一个结论:为什么任何人都有必要举起一袋盐? Salt can be supplied in super sacks weighing up to 2,000 pounds. We now have equipment available that can deliver the salt with ease, 唯一需要做的工作就是用叉车把超级袋子放到合适的位置，以便运送到储罐. 这解决了人们对更轻的袋子的渴望，并使工人更快乐，工伤也更少.
Q: Have any of your customer’s taken advantage of the super sack option?
JD: Yes, as a matter of fact, they have. 一名顾客对改用超级麻袋的结果表示:“我们再也不会去搬袋子了,” with the operators on the salt line all nodding in agreement.
问:在热处理中一直使用盐吗?目前的趋势是什么?
JD: Using salt as a quench medium has been around since the mid-1950s. 从那时起，它已经发展成为一个具有不断扩大的可能性和用途的可行市场. Salt is hard to beat in terms of a quench medium and its capabilities. For austempering, no other medium or process can match salt. 越来越多的公司正在安装系统，以便更好地控制他们生产的产品的冶金过程.
Q: Tell us about Hubbard-Hall’s line of products and how facilities are using them in their processes; let’s start with the Neutral Salt series: A, B, BS和C.
JD:澳门威尼斯人网上赌场网站提供了我们每一种中性盐产品的详细信息，很容易访问. 中性盐系列产品虽然用于高温工艺，但特定于所处理的金属和/或合金类型. Neutral Salt B, 例如, is selected for the majority of austempering operations working with carbon steel. 它是氯化物化学物质的混合物，能够达到并保持适当热处理所需的高温.
Q: Hubbard-Hall also has the Quick Temper series: 275, 300 and 430 for both quenching and tempering, but also for austempering, martempering and isothermal quenching. Which ones should facilities be using for their operation?
JD: The Quick Tempers, which are a blend of nitrate and nitrite chemistries, are all used primarily as
a quench medium subsequent to the high heat process. The numbers associated with each Quick Temper product indicates its melting point. 一些客户选择快速温度275，如果他们在较低的温度淬火，以获得更高的硬度正在处理的工作. 由于其最佳工作温度范围，Quick Temp 300是最常用于等温回火的淬火盐. 再一次。, 我们的网站提供了这些产品的详细信息，以便客户可以确定哪种产品最适合他们的特定需求.
Q: The other Hubbard-Hall product is the Quick Cure 420; how is that product used by customers?
JD:快速固化420已经作为盐介质用于硫化橡胶制品几十年了. Like all of our salt products, 快速固化420是一种纯技术级盐混合物，橡胶制造公司在其挤出橡胶产品上使用该盐进行固化.
Q: If a manufacturer asked you why they should switch to Hubbard-Hall products, what are a few reasons you’d give them?
JD: It goes beyond just supplying top-grade products. 澳门威尼斯人网上赌场是一家家族企业，将客户视为家族的一部分. 我们的客户发现澳门威尼斯人网上赌场真正以客户为导向，对他们的要求和化学品需求非常敏感. We pride ourselves on all aspects of satisfying our account base. From providing quality controlled chemistry to on-time delivery, our customers are assured our best efforts to continually earn their trust. In fact, 35% of Hubbard-Hall’s team members are customer interactive. Along with safety, customers are always our first priority.
