Abstract

To study the characteristics of fire traces of rock wool color steel plates in fire field, two kinds of heat sources, muffle furnace and oil pan fire, are used to simulate the fire site. Firstly, given the simulation of fire field radiation under ideal conditions, the thermal radiation temperature of muff furnace was adjusted to study its influence on the characteristics of fire traces. Secondly, with a stable combustion heat source of oil pan fire, the heating condition was changed by controlling the distance between the color plate and oil pan. Finally, the trace characteristics of core and metal sheet were observed after heating. The results show that with the increase of temperature, the core appears to be fluffier. It will shrink and deform at 600 ℃ and get cracking at 1 000 ℃, and metal plates also show damages at various degrees with paint falling off and pits, cracks and other damage marks these results provide a basis for determining fire spreading direction, fire location and point in fire investigation of color steel plate buildings. © 2019 China Safety Science Journal.
