Problems solved by technology

However, due to the high iron content of basalt, it is very easy to have a replacement reaction with the molybdenum electrode, resulting in a short service life of the kiln due to corrosion of the molybdenum electrode.
Therefore, the production cost of the product is high, and the product quality defect is many.
And in the kiln of a kind of production basalt fiber described in CN104692647A, although change kiln from rectangle to circular, although can improve certain production efficiency, can not change the kiln service life that molybdenum electrode plate erosion causes And the status quo of low product quality, this is also as of the beginning of 2015, the annual output of continuous basalt fiber in my country is only about 5,000 tons, which is directly related to the kiln of continuous basalt fiber

Abstract

The invention relates to a basalt continuous fiber furnace with a bottom-inserted electrode, comprising a melting tank (2). The melting tank (2) is provided with a feed port (1); a rod molybdenum electrode (6) is inserted into the bottom of the melting tank (2), the rod molybdenum electrode (6) is sleeved with a cooling device, and the rod molybdenum electrode (6) is connected with a Scott transformer through a lead (9). It is possible to effectively improve melting efficiency of basalt.

Description

technical field [0001] The invention relates to the electromelting preparation of continuous basalt fibers, in particular to a continuous basalt fiber kiln with bottom-inserted electrodes. Background technique [0002] Basalt has been unable to improve its melting effect due to factors such as high melting temperature, black color, and strong erosion. Since the 1980s, the former Soviet Union has used the shallow melting method of top flame melting, but it is inefficient in the drawing process. And in the alkali-resistant basalt fiber manufacturing method, product and equipment as described in CN00110460, utilize plate electrode to melt basalt fiber. However, due to the high iron content of basalt, it is very easy to have a replacement reaction with the molybdenum electrode, resulting in a short service life of the kiln due to corrosion of the molybdenum electrode. Therefore cause product production cost height, product quality defect is many. And in the kiln of a kind of ...
