    • A cam shaft manufacturing process wherein a cam shaft is cast from a heat-treatable gray cast iron having a high carbide microstructure, is annealed while retaining the carbides and then cooled to room temperature. Surfaces, such as cam lobe surfaces, are then surface hardened and the cam shaft may thereafter be machined. The heat treating process comprises heating the cam shaft at 1600.degree. F. (871.degree. C.) in about twenty minutes, holding the cam shaft at 1600.degree. F. (871.degree. C.) for about twenty minutes and thereafter heat treating the cam shafts at a temperature of 1600.degree. to 1640.degree. F. (871.degree. to 893.degree. C.) for about eighty minutes. The cam shafts are then cooled rapidly to about 400.degree. F. (204.degree. C.), for example, within about an hour and a half, and thereafter air cooled.
    • 凸轮轴的制造方法,其中凸轮轴由具有高碳化物微观结构的可热处理的灰口铸铁铸造,同时保留碳化物,然后冷却至室温。 然后,诸如凸轮凸角表面的表面被表面硬化,然后可以加工凸轮轴。 热处理工艺包括在大约二十分钟内在1600°F(871℃)下加热凸轮轴,将凸轮轴保持在1600°F(871℃)约20分钟,然后热处理凸轮 轴温度为1600°至1640°F(871°至893℃)约80分钟。 然后将凸轮轴快速冷却至约400°F(204℃),例如在约一个半小时内,然后空气冷却。

    • A process for concentrating and diluting a treatment substance to provide a diluted treatment for introduction to a wellbore is disclosed. In one embodiment, the process includes measuring a treatment fluid flow rate. The process also includes blending the treatment fluid with a treatment substance to produce a concentrated treatment fluid. The process further includes measuring a flow rate of the concentrated treatment fluid. Moreover, the process includes determining a difference between the treatment fluid flow rate and the flow rate of the concentrated treatment fluid. In addition, the process includes comparing the difference to a target difference. The process additionally includes adjusting the difference to be within a desired range of the target difference and diluting the concentrated treatment fluid to provide the diluted treatment fluid.
    • 公开了一种用于浓缩和稀释处理物质以提供用于引入井筒的稀释处理的方法。 在一个实施例中,该方法包括测量处理流体流速。 该方法还包括将处理流体与处理物质混合以产生浓缩处理流体。 该方法还包括测量浓缩处理流体的流速。 此外,该方法包括确定处理流体流速与浓缩处理流体的流量之间的差异。 此外,该过程包括将差异与目标差异进行比较。 该方法另外包括将差异调整在目标差异的期望范围内,并稀释浓缩的处理流体以提供稀释的处理流体。
