Problems solved by technology

The existing electric melting furnace basically has such a structure, which has the following disadvantages: 1. Generally, the two-sided electrodes are used to extend into the furnace wall to heat the materials in the furnace. This method requires separate control of the electrodes on both sides. , easily lead to the problem of uneven heating; 2. Generally, it takes a long distance for the material to be transported from the bottom of the melting tank to the working channel to reach the position of the bushing plate for the process of drawing continuous fibers. The distance between the pool and the working channel (drawing forming area) is long, which not only increases the production cost of the electric melting furnace and the loss cost of electric energy, but also prolongs the preparation time for continuous fiber production and reduces production efficiency.

Embodiment 2

[0043] In this example, see Figure 5 with Image 6 , different from Embodiment 1, a second blocking brick 310 is also arranged between the blocking brick 300 (the first blocking brick) and the forehearth 102, the second blocking brick 310 is arranged side by side with the blocking brick 300, and the second blocking brick 310 and the The blocking brick 300 has the same structure, and also has a second central part for accommodating the second cooling device and a second peripheral structure wrapping the second central part. Similarly, the top of the second blocking brick 310 is fixed on the top of the melting pool The inner wall, the bottom of the second block brick 310 and the bottom of the melting pool have a second preset height for conducting the solution, and the second preset height is less than the preset height (the preset height is the bottom of the above block brick and the melting tank). The preset height h) formed by the bottom of the pool, the distance between th...

Abstract

The invention discloses an electric melting furnace for producing continuous basalt fibers. Theelectric melting furnace comprises a furnace body and an electric melting control device, a melting tank, a material channel, a working material channel and a working chamber are sequentially arranged in the furnace body, a feeding part is arranged above the melting tank, and a baffle brick is arranged between the melting tank and the material channel; the baffle brick is provided with a center part used for containing the cooling device and a peripheral structure wrapping the center part. The top of the baffle brick is fixed to the inner wall of the top of the melting tank, and the bottom of the blocking brick and the bottom of the melting tank have a preset height for communicating a solution. By means of the structure, a throat and an electrode structure in the prior art are improved, and the baffle structure is added, so that the distance from the bottom of the melting tank to the material channel is shortened by about 4 / 5 than that of a throat shrinkage structure. Due to arrangement of the electrodes in the single side, heating is more uniform, heat losses are reduced, and therefore the construction cost of the electric melting furnace is greatly reduced, energy consumption losses are reduced, and the production efficiency of continuous fiber production is improved.

Description

technical field [0001] The invention relates to the technical field of basalt fiber production equipment, in particular to an electric melting furnace for producing continuous basalt fiber. Background technique [0002] Basalt fiber is a continuous fiber drawn from natural basalt. It is a continuous fiber drawn through a platinum-rhodium alloy drawing bushing at high speed after the basalt rock is melted at 1450 ° C to 1500 ° C. Basalt fiber is a new type of inorganic environmentally friendly green high-performance fiber material, which is composed of oxides such as silicon dioxide, aluminum oxide, calcium oxide, magnesium oxide, iron oxide and titanium dioxide. Basalt continuous fiber not only has high strength, but also has various excellent properties such as electrical insulation, corrosion resistance, and high temperature resistance. In addition, the production process of basalt fiber determines that less waste is produced, less environmental pollution, and the product...
