Problems solved by technology

[0006] In the prior art, the ore melting process adopted is still unable to penetrate high-temperature impurities such as quartz, mica, and porphyrite, and it is also difficult to ensure the excellent melt quality requirements and the uniformity of melt quality requirements and fiber forming. Requirements for the degree of stereotyping
In addition, in order to achieve a higher melting temperature, it is necessary to keep the flame space of the entire melting furnace at a higher temperature, which consumes a lot of energy
In most reported basalt fiber production methods and equipment, ore melting and melt mass homogenization are two separate processes, which are carried out in different process sections of the melting furnace (Chinese patent ZL97199852.3, Chinese patent application 98114321.0), and the distance between each process section in the melting furnace is relatively long, so the production process and equipment structure are complicated, and the economy is not good enough

Embodiment

[0057] Embodiment: Utilize the equipment shown in accompanying drawing to produce the molten body required for continuous basalt fiber

[0058] The raw material of basalt ore is basalt ore containing 2-3% quartz, and the chemical composition (by weight) of basalt is: SiO 2 51%, Al 2 o 313%, Fe 2 o 3 ·FeO11%, TiO 2 2.5%, CaO10%, MgO·MnO5.2%, K 2 O3.5%, Na 2 O3.8%.

[0059] The production device adopts a 200-hole drawing bushing, and its production capacity for continuous basalt fibers with a fiber diameter of 6-13 microns is 8kg / h-12kg / h.

[0060] The basalt ore fragments with a screen size of 3-25mm are sent to the melting working platform in the furnace body of the ore melting furnace through the burner-feeder on the roof of the melting furnace in batches, and the feeding amount is controlled by the feeder meter. The dosing parameters were set to add 80-90 grams of ore over a period of 80 seconds. In the melting zone, a melting working platform with an area of ​​400×...

Abstract

The invention relates to ore melting and molten mass adjusting method in continuously basalt fiber producing process. It completes the milting process under the condition of low molten mass level height in melting technology process of localized heating in melting furnace. The invention could effectively melt ore, equalize the mass, and remove air bubble. And it increases the melt temperature of ore to achieve the effect of increasing kinds of fiber and improving quality.

Description

technical field [0001] The invention relates to a method and equipment for basalt ore melting and melt preparation, and more particularly to a method and equipment for ore melting and melt production in the continuous basalt fiber production process. Background technique [0002] Basalt, andesite basalt, basanite, diabase, gabbro, coarse-grained basalt, amphibolite, andesite porphyrite are all volcanic magmatic rocks, all of which have very high chemical and thermal stability. [0003] Fibers made from basalt ore, that is, basalt fibers have excellent properties such as high strength, high chemical stability, high thermal stability, and good electrical insulation. Therefore, basalt fibers have broad application prospects and can be used in different industrial fields. [0004] There are a large number of basalt deposits in China, so the ore raw material resources for basalt fiber production are extremely rich, but due to the limitation of complex production technology and ot...
