Basalt fiber manufacturing process

Abstract

The invention relates to a basalt fiber manufacturing process. The process comprises the following steps: crushing the basalt raw ore, and then placing the crushed ore into mixing equipment to be mixed; grinding parts of materials in the mixing equipment according to a multi-draw manner, and then mixing the ground parts; preparing the uniformly mixed material powder into specimens, and detecting the phase of the specimens; if the detection result is in accordance with the standard of the basalt fiber, directly adding the materials into a tank furnace; otherwise, according to the difference between the detection result and the standard, adding corresponding components, uniformly mixing the materials added with the corresponding components, and feeding the mixture into the tank furnace; utilizing a heating electrode to heat the materials in the tank furnace, enabling the materials to be molten, and when the liquid level of the melt is raised to be coincident with a liquid level base plate at the front end of a monitoring rod, performing delayed heating; opening a discharge hole at the bottom of the tank furnace to enable the melt to flow out through a bushing plate, and then using a bushing blower to cool the melt, so as to form the fiber. The basalt fiber manufacturing process disclosed by the invention can improve the stability of the product quality and reduce waste of the product resources.

Description

technical field [0001] The invention belongs to the technical field of basalt product processing, and relates to a basalt fiber manufacturing process. Background technique [0002] Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material. It is composed of basalt rocks composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, iron oxide and titanium dioxide. drawn. The traditional process is that after the basalt is crushed and cleaned, the basalt block with a diameter of 50-60mm is put into the tank kiln by the feeding equipment, melted, homogenized and degassed at a temperature of about 1500°C, and then flow out from the leaking plate to form , the fibers are formed under the forced cooling of the blowing equipment, and then wound on the winding drum of the head of the wire drawing machine after being bundled. [0003] When basalt is used as a single raw material, it must have a definite chemical composition,...

Problems solved by technology

Therefore, unqualified basalt raw ore can only be eliminated, resulting in a great waste of minerals

Not only that, for the same batch of basalt raw ore, due to the inhomogeneity of its composition, even if multi-point sampling testing is used, the results will still be uncertain, resulting in unstable fiber processing quality
