内容简介

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. 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.
