Problems solved by technology

[0003] In the tank kiln for continuous basalt fiber production, the liquid flow hole is located between the melting zone and the channel, and is used to connect the furnace and the main forehearth. Platinum-rhodium alloy, high cost, and there is no heating and temperature control device in the liquid flow hole, so the homogenization of the melt cannot be well achieved, which eventually leads to uneven quality of basalt fiber

Abstract

The invention provides a throat for producing continuous basalt fiber, relating to the field of processing of inorganic non-metal materials. The throat comprises a throat bottom, throat walls and a throat top; electrodes and a temperature control device are arranged in the throat; each of the throat bottom, the throat walls and the throat top is of a multi-layer structure; the throat bottom and the throat walls are made of fireproof materials; the outermost layer of the throat top is coated with a steel plate; and a fireproof material is filled in the steel plate. According to the throat for producing continuous basalt fiber, provided by the invention, the fireproof materials are used for replacing platinum-rhodium alloy, so that high temperature resistance and scouring resistance are realized, and the cost is saved; and heating devices, namely the electrodes, are arranged in the throat, and the temperature control device is used for adjusting the temperature in the throat so as to ensure the homogenization of melt, so that basalt fiber with uniform quality can be produced.

Description

technical field [0001] The invention relates to the field of processing inorganic non-metallic materials, in particular to a flow hole 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 advantages.
