[0002] At present, the feeding method of flame furnaces used for basalt fiber production in China is mostly top-loading, that is, there is a feeding hole preset at the top of the flame furnace, and a feeding funnel is installed at the top of the hole. The feeder feeds the basalt raw materials into the furnace through the feeding funnel through the feeding hole according to a certain particle size ratio, and the raw materials are replenished and melted, so as to carry out continuous production operations. Due to the high melting point of basalt, about 1450-1550℃, the flame atmosphere temperature of the entire flame furnace space is relatively high, so the temperature resistance of some devices installed on the top of the furnace is relatively high, such as the feeding funnel, flame combustion nozzle and other devices. These devices are mostly made of stainless steel or heat-resistant cast iron with good temperature resistance to meet the requirements of high-temperature use environment. In a high-temperature use environment, the feeding funnel is very easy to be deformed by heat, and the impact of the raw materials on the funnel during the feeding process makes the feeding funnel more easily deformed. At the bottom of the funnel near the flame, due to long-term high-temperature radiation, it may even soften and melt.
