  • 产品描述
    • 商品名称: DOW 陶氏化学 UCON 淬火剂 HT - 54 加仑

    UCON™ Quenchant HT 是陶氏化学公司生产的一种不易燃聚合物淬火剂。它是液体有机聚合物和腐蚀抑制剂的水溶液。

    有机聚合物可溶于水并产生均匀的溶液。然而,在温度高于 88°C (190°F) 时,聚合物会以不溶相的形式与水分离

    当铁水在 UCON Quenchant HT 的稀释溶液中淬火时,液态有机聚合物薄膜会沉积在铁水表面。金属冷却的速率部分取决于富含聚合物的薄膜的厚度。该膜的厚度由淬火槽中 UCON Quenchant HT 的浓度控制。

    还通过调节淬火浴温度和/或搅拌速率来控制冷却速率。

    UCON Quenchant HT 与其他 UCON Quenchant 的主要区别在于前者的分离温度较高。

    这为选择初始熔池温度和淬火循环期间允许的终止温度提供了更大的灵活性。

    表现

    • UCON Quenchant HT 更宽的温度范围使其适用于间歇式整体淬火炉。然而,由于设备设计的差异,每次安装都需要单独注意才能提供令人满意的性能。
    • UCON Quenchant HT 很容易适用于感应淬火,包括喷雾淬火和浸入淬火,适用于齿轮、曲轴、凸轮轴以及其他复杂几何形状和不同冶金学的零件。
    • UCON Quenchant HT 可以遵循振动式、旋转式或连续式设计的氧化或保护气氛炉。可用于锻件直接淬火;用于连铸淬火;以及锻钢、铸钢和铸铁的一般淬火。

    好处

    • 根据最新测试标准,FM Approvals 已将 UCON Quenchant HT 归类为“FM 批准”。
    • 特定金属或零件的最佳操作条件可以通过控制浓度、浴温和/或搅拌来确定。
    • UCON Quenchant HT 因其分辨率更高的温度而最大限度地减少拖曳。主要的补充要求是蒸发损失的水。
    • UCON Quenchant HT 可消除油淬火剂常见的烟雾、烟灰和残留物。设备维护和工厂清洁更容易实现和维护。
    • UCON Quenchant HT 可溶于水,并且能抑制细菌生长。
    • UCON Quenchant HT 将在 0°C (32°F) 以下结冰。使用前应解冻至室温并混合。产品不会受到任何影响

     

    应用领域

    • 从以前需要油淬的倾斜炉中硬化大型合金零件。
    • 在需要较高熔池温度的情况下直接淬火的硬化锻造零件。
    • 需要渗碳气氛的整体淬火炉。包含溜槽淬火系统的气氛炉

     

    DESCRIPTION

    UCON™ Quenchant HT is a nonflammable polymeric quenchant manufactured by The Dow Chemical Company. It is an aqueous solution of a liquid organic polymer and acorrosion inhibitor.

    The organic polymer is soluble in water and produces a homogenous solution. At temperatures above 88°C (190°F), however, the polymer separates from water as an insoluble phase

    When hot metal is quenched in a diluted solution of UCON Quenchant HT, a film of the liquid organic polymer is deposited on the surface of the hot metal. The rate at which the metal is cooled is governed, in part, by the thickness the polymer rich film. The thickness of this film is controlled by the concentration of UCON Quenchant HT in the quench bath.

    The cooling rate is also controlled by adjusting the quench bath temperature and/or the rate of agitation.

    The major difference between UCON Quenchant HT and other UCON Quenchants is the higher separation temperature of the former.

    This provides greater flexibility in the selection of initial bath temperature and in the permissible run-out temperature during the quench cycle.

    PERFORMANCE

    • The broader temperature range for UCON Quenchant HT makes it adaptable to batch type integral quench furnaces. However, because of variations in equipment design, each installation will require individual attention to provide satisfactory performance.
    • UCON Quenchant HT is readily adapted to induction hardening, both spray quench and immersion, for such items as gears, crankshafts, camshafts, and other pieces of intricate geometry and different metallurgy.
    • UCON Quenchant HT may follow either oxidizing or protective atmosphere furnaces of shaker, rotary or continuous design. It may be used for direct quenching from the forge; for continuous cast quenching; and for general hardening of forged and cast steels, and cast irons.

    BENEFITS

    • FM Approvals has classified UCON Quenchant HT as “FM Approved” as tested against the latest testing criteria.
    • The optimum operating conditions for a specific metal or part may be determined by control of concentration, bath temperature, and/or agitation.
    • UCON Quenchant HT minimizes dragout because of its higher resolutioning temperature. The major make-up requirement is for water lost by evaporation.
    • UCON Quenchant HT eliminates the smoke, soot and residues common to oil quenchants. Equipment maintenance and plant cleanliness are easier to achieve and maintain.
    • UCON Quenchant HT is soluble in water and is resistant to bacterial growth.
    • UCON Quenchant HT will freeze below 0°C (32°F). It should be thawed to room temperature and mixed before use. The product will not be affected in any way

     

    APPLICATIONS

    • Hardening large alloy parts from tilt-top furnaces that previously required an oil quench.
    • Hardening forged parts that are quenched directly where higher bath temperatures are required.
    • Integral-quench furnaces requiring carburizing atmospheres. Atmosphere furnaces containing chute quenching systems
