Description

technical field [0001] The invention relates to the field of processing inorganic non-metallic materials, in particular to a kiln feeding device for producing continuous basalt fibers. Background technique [0002] The continuous basalt fiber is made of natural volcanic extrusive rock as raw material, which is crushed and put into the melting furnace. After melting at 1450-1500 ℃, it is a continuous fiber made by drawing bushings. Compared with carbon fiber, aramid fiber, ultra-high molecular weight polyethylene fiber (UHMWPE) and other high-tech fibers, it has many unique advantages, such as good mechanical properties, good high temperature resistance, and can be used continuously in the range of -269 to 650 °C. Work, acid and alkali resistance, strong UV resistance, low moisture absorption, better environmental resistance, in addition, it has good insulation performance, high temperature filterability, radiation resistance, good wave transmission performance and other adva...
