Embodiment Construction

[0014] Raw materials are fed into the kiln through the feeding port (2) and melted in the melting tank (3). Its heating method can be electric plate or fuel burner. Between the melting pool (3) and the working area, a partition wall (5) is provided to completely separate the spaces of the two parts. Under the partition wall (5), a flow hole (6) is established, and the melting body that has been melted in the melting pool (3) enters the vertical ascending channel (7) of the work area through the flow hole (6), and the passage (7 ) is lower than the liquid level of the melt. The melt is degassed and homogenized during its ascent. Thereafter, the melt forms a thin overflow strip (10) on top of the heat shield (8). During the forward process, further degassing and homogenization.

[0015] The degassed and homogenized melt flows down the skirt plate (13) into the melt pool (12) in the working area. A semi-cylindrical chute (14) is provided below the skirt plate (13), the purpo...

Abstract

It consists of tank furnace body, feed charging hole, melting tank, separating wall, heat shield, molten mass thin layer ovrflow band, working cell, moltenmass tank, skirboard, downspouting, feeding pipe and bushing, separating wall is built between melting tank and working area to prevent disturbing and ensure stability of technology parameter. Vertical rising channel is beneficial to molten mass is homogenized and degassed progressively in process from melting tank to working area, heat shield is beneficial to heat molten mass in the working cell and uniform temp., thin layer molten mass overflow band is used to clear the thin layer, the action of downspouting is to create vortex to molten mass flowing into working cell along skirtboard to mix and uniform new molten mass and old one, stirring machine is set in working cell to uniform stir molten mass, feeding pipe is set in sealing unit in working cell to draw materials from middle but top and bottom to ensure quality of molten mass flowing wire-drawing operation bushing and parameter stability.

Description

technical field [0001] The invention relates to a basalt fiber, in particular to a tank kiln for producing continuous basalt fiber, and belongs to the technical field of international patent classification C03B37 / 01. Background technique [0002] Basalt fiber made from basalt is a high-grade thermal insulation material with good fire resistance, strong acid resistance, low water absorption and high elastic modulus. It is used in aerospace, aviation, metallurgy, shipbuilding and many other fields. Basalt itself is a kind of volcanic extrusive rock, which has the characteristics of high melting temperature, easy crystallization and high iron content, and belongs to refractory material. In the prior art, flame method, all-platinum crucible material, etc. are used, but the melting efficiency is low. Contents of the invention [0003] The object of the present invention is to overcome the above-mentioned defects, and provide a kind of tank kiln for producing continuous basalt...
