3 Overview

The coal ash fusibility measuring instrument comprises a measuring instrument for manually monitoring the morphological change of the sample and determining the characteristic temperature, and the observation recorder can be self-contained A tester that records the change in the shape of the sample, a tester that can automatically determine the characteristic temperature, and the like, the performance should be in accordance with GB/T 219. Provisions. The working principle is as follows. the ash sample is made into a triangular cone of a certain size, and heated in a certain gas medium at a certain heating rate. Observe the morphological change of the ash cone during the heating process, observe and record its four characteristic melting temperatures. deformation temperature (DT), softening temperature (ST), Hemisphere temperature (HT) and flow temperature (FT). 1 and 2 are the basic structures of a horizontal analyzer and a vertical analyzer, respectively. Description. 1---high temperature furnace; 2---heating furnace; 3---observation recorder; 4---temperature controller. Figure 1 Schematic diagram of the horizontal coal ash melting tester ......
