Oven Boosts Energy Efficiency in Drying Cores, Molds 提高烘干芯和型的能效
Faced with increasing environmental regulations limit- ing emissions of volatile organic compounds (VOCs), the metalcasting industry has significantly increased its use of water-based binders for cores and molds. When exposed to molten metal, these binders emit fewer air pollutants. Increased use of these refractory coatings means facilities need an efficient and precise method of drying such coatings after casting. To meet growing demand among its metalcasting cus-
tomers, LaX Engineered Solutions LLC, Waukesha, Wis., has developed its line of patent-pending Cyclone ovens. Te high volume, low pressure airflow in the Cyclone ovens provides drying times that can increase throughput while decreasing the size of the equipment envelope. Designed specifically for the metalcasting industry,
the new Cyclone oven includes multiple drying zones to increase process flexibility. Te control system allows metalcasting engineers to vary and control the temperature, airflow and conveyor speed. Additionally, the electronic control allows the customer to dial in the amount of exhaust for maximum efficiency. “We are pleased with the flexibility of design and the
adjustable belt speed to optimize drying times for varying size cores,” said an engineer at a metalcasting facility that
随着环保法对于挥发性有机化合物（VOCs）排放 日益严格的限制，铸造行业已显著提高了水基粘结 剂在制芯和模具中的使用。当这种粘结剂用于熔融 金属时，它们释放较少的空气污染物。此类耐火涂 料使用的增多，意味着企业需要有效且精确的铸造 后涂料干燥法。
为了满足客户不断增长的需求，威斯康辛州沃基肖 的LaX工程公司已研发了悬空气流烘箱生产线，并已 申请专利。该气流烤箱的高容量、低压气流在干燥时 间内，可在提高效率的同时减小设备的外形尺寸。 新型气流烘箱专为铸造行业设计，有多个干燥区 域，以提高操作的灵活性。烘箱的控制系统使铸造 工程师可以改变和控制温度、气流和传输速度。此 外，电子控制设备使客户可以将排气量调节为最大 效率。
已安装了LAX公司气流烘箱的一家铸造企业的工 程师说：“气流烘箱灵活性的设计以及可调节的皮 带速度，可以优化不同尺寸砂芯的干燥时间，我们 对此很满意。砂芯可以在较低的温度下快速干燥， 并大大改善了工艺。”
The Cyclone oven was designed to maximize efficiency when drying cores and molds treated with water-based binding compounds.
