1.1本试验方法描述了将耐火材料的性能与旋转试验炉中熔渣的作用进行比较的程序。每次测试和运行中应包括一种参考材料，以进行比较。本试验方法未获得数值结果。测试结果的数值评估由测试操作员负责。试验和设备采用Valley Dolumite Corporation开发的方法。 1.2以英寸-磅为单位的数值应视为标准值。括号中给出的值是到国际单位制的数学转换，仅供参考，不被视为标准值。 1.3 本标准并非旨在解决与其使用相关的所有安全问题（如有）。本标准的用户有责任在使用前制定适当的安全和健康实践，并确定监管限制的适用性。 ====意义和用途====== 本试验方法概述了一个程序，当添加适当的评估方法时，该程序可用于开发新产品或选择与特定炉渣成分接触的产品。 通过试样存在梯度，该梯度由试样和备用材料的导热系数控制。熔渣不断更新，以保持较高的腐蚀速率。熔渣的流动会导致材料的机械侵蚀。熔炉的倾斜和旋转速度将影响机械侵蚀量。 当在一次运行中包含不同类型的材料时，在解释结果时要小心。在加热过程中，必须注意防止含碳材料氧化；否则可能会导致非常不稳定的结果。应使用参考耐火材料试样进行比较。

1.1 This test method describes a procedure for comparing the behavior of refractories to the action of molten slag in a rotating test furnace. A reference material should be included in each test and run for comparison. No numeric results are obtained from this test method. Numeric evaluation of test results is the responsibility of the test operator. The test and equipment are patterned after a method developed by Valley Dolomite Corporation. 1.2 The values stated in inch-pound units are to be regarded as standard. The values given in parentheses are mathematical conversions to SI units that are provided for information only and are not considered standard. 1.3 This standard does not purport to address all of the safety concerns, if any, associated with its use. It is the responsibility of the user of this standard to establish appropriate safety and health practices and determine the applicability of regulatory limitations prior to use. ====== Significance And Use ====== This test method outlines a procedure which, when appropriate evaluation methods are added, can be useful in the development of new products or in the selection of products to be used in contact with a particular slag composition. A gradient exists through the test specimens that is controlled by the thermal conductivity of the specimens and backup material. The slag is constantly renewed so that a high rate of corrosion is maintained. The flow of the slag can cause mechanical erosion of materials. The tilt and rotational speed of the furnace will affect the amount of mechanical erosion. Use caution in interpreting results when materials of vastly different types are included in a single run. Care must be taken to prevent oxidation of carbon-containing materials during heat up; failure to do so can result in highly erratic results. A reference refractory specimen, or specimens, should be used for comparison.
