This paper studies a technique for estimating fire patterns by analyzing the amount of change in material components. The background of the experiment is to find a method that can help people with less than two years of fire investigation practice find the ignition point. A total of 6 types of test samples were selected, including 4 types of steel plates, a front door collected from a fire site, and a brick building After heating the steel plate at a temperature of 700℃ for 1800s on a sample of 700mm in width and 700mm in length, An experiment was conducted to estimate the Fire pattern at the ignition point by analyzing the component change of the surface in the non-irrigated and watered state, and objective verification was conducted on the field applicability of this study using samples collected from the fire site. For each sample, changes such as Fe component rising and Zn component falling above the melting point were confirmed. By connecting sectors with a high rate of change, the fire pattern was completed and the ignition point was found, The change was greater in the watered state than in the non-watered state. The reason is that the surface is oxidized by water and the change is large. All experimental data are displayed in colors, graphs, and amount of change for easy interpretation, and reliability of data is improved by analyzing in three directions (X, Y, and Z axes) rather than in one direction. Through this material component analysis, it was possible to estimate the fire pattern, and based on this, it was confirmed that the ignition point could be found.
