Burning surface (flamed): refers to the rough surface finish processed by using acetylene, oxygen or propane, oxygen, or liquefied petroleum gas, oxygen as fuel to produce high temperature flame on the surface of stone. There are a few stones that cannot be processed by fire or the effect is not good. Due to the effect of the fire, some impurities and low melting point components on the surface of the stone can be burned, thereby forming a rough finish on the surface, which will give a certain tingling sensation to the touch. The processing of the fire surface has certain requirements on the thickness of the stone to prevent the stone from cracking during the processing. Generally, the thickness is required to be at least 2CM, and some stones have higher thickness requirements. In addition, some materials will change color during the fire process, such as rust stone (G682), the rust stone after the fire will show a certain light red instead of the original yellow rust color. The characteristics of the fire surface are rough and natural surface, non-reflective, fast processing, and relatively cheap. It is often used for dry hanging on external walls.
Fire surface treatment is mainly suitable for crystalline stones containing quartz, such as granite and hornblende. This kind of stone will instantly expand and peel off the crystalline part of the surface layer under the rapid jet high temperature flame, which is more natural. However, when flame processing was used to treat the surface of stone, there was no special flame processing device. Instead, the flame stone cutter or perforator with a flame temperature of 300℃ and a jet speed of 1200m/s was used to perform flame processing on the stone surface based on experience. , It is difficult to control the jet speed and flame temperature. However, it is very difficult to heat only the surface layer of the stone under the above-mentioned extremely fast jet speed and extremely high flame conditions, because not only the surface layer, but also the inner layer may be heated by high temperature and melt, deteriorate and change color, not only can not achieve flame processing The expected effect also damages the inherent natural color of the stone.
In order to achieve the purpose of facilitating and effective processing of the stone surface, the key is to control the spray speed and flame temperature. Therefore, it has been proved through repeated tests that the spray speed and flame temperature on the stone surface are controlled at 400~1000m/sec and 2000℃~2500℃ respectively. Within range
