数据是在高达280°C的温度下获取的，并且空气速度每秒高达4米。氧化烤箱中最关键的性能指标之一是空气速度均匀性。Harper的氧化烤箱均匀性的尺寸为2.2％。
整个拖曳带的空气速度均匀性是必不可少的，因为PAN稳定阶段是放热反应。如果速度区域较低，则反应可能会逃跑，从而导致偏移。如果速度较高，则可能会损坏细腻的锅纤维。
Harper’s design also demonstrated temperature uniformity of +/- 2.5 °C throughout the entire heated length.
温度均匀性在碳纤维制造中至关重要，因为它可以提高生产率。随着较高的生产率导致更宽，更高和更长的氧化烤箱，这是提高速度和温度均匀性同时增加烤箱尺寸的速度和温度均匀性的关键挑战。
Harper的高级流程技术工程师Bill Stry和Renee Bagwell评论说：“ Harper的烤箱设计为我们的客户提供了增强的性能和增强对纤维制造的信心。”
“我们承担了工程氧化烤箱的任务，该烤箱涉及今天和明天的市场DEM和效率和质量，以及在完整测试中获得的数据表明我们的成功。”
