    摘要: The invention relates to a method for producing continuous shopped, coarse, staple inorganic fibres from such natural minerals and rocks as sand, quartz, reduced quartz sand stone and quartzite. The inventive method consists in melting silicon-based stone, which is used in the form of a raw material, at a temperature of 1750-1850° C., the melt being homogenated and stabilised at said temperature, in forming a decompression zone on the path of the melt flow to the discharge orifice die, in which the melt flow is shaped in the form of a strip with a thickness of 3-20 mm, and in passing said strip through the decompression zone at a speed V=(7 . . . 9)10−4 m/s. The air pressure in the decompression zone above the melt flow is maintained within a range of 0.10-0.30 Pa. The inventive device comprises a furnace for producing melt, a feeder, at the output of which a transfer chamber is mounted, a discharge orifice, a stream feeder assembly and a fibre producing mechanism. A homogenizer in the form of two cylinders, which are vertically and coaxially arranged with a gap one inside the other, is situated between the furnace and the feeder. A vertical baffle for producing a melt flow in the form of a strip is placed in the external cylinder. A clarifying chamber is provided with a unit for forming vacuum in the cavity thereof. Said invention makes it possible to increase the strength and chemical resistance of produced fibres by providing conditions for reducing the number of foreign, in particular, gaseous inclusions.

The inventive method consists in loading a ground composition in a melting furnace, in melting said composition, in homogenizing a melt, in consequently stabilizing the melt in the melting furnace feeder, in drawing and oiling the fiber and in winding it on a spool. Prior to loading, the composition is held in an alkali solution for 15-20 minutes, and is then washed with flowing water for 20-30 minutes and dried. After having been washed with flowing water, the dried composition is loaded into the melting furnace.

    摘要: The present invention pertains to plants for producing inorganic fibers from melted rocks, advantageously, with narrow working interval and low diathermy, for example, basalts, diabases, amphibolites, andesites, dacites, rhyolites and other rocks. The plant comprises the furnace for obtaining the melt connected to the feeder, working aperture and a warmed feeder with draw dies located below working aperture where, according to the invention, transition chamber is installed on the feeder exit, such transition chamber is intended for creation of thin layer melt flow, its enclosure contains working aperture, the transition chamber has the heater, the threshold installed at its entrance and adjustable damper located over the threshold, and these components are intended for obtaining the melt flow of needed thickness and quality. The feature of the proposed invention is also the bottom of the transition chamber which has an inclination directed towards the working aperture. The plant has also accumulator tank installed between the exit of the furnace for obtaining the melt and the feeder, which is intended for receiving the melt homogeneous in ten is of composition and temperature. Another feature of the plant is that the plant has the unit for removing iron containing impurities from the melt, such unit being the source of direct or pulsing current with electrodes installed at the feeder entrance, connected to corresponding poles of the current source and intended for creating electric current in the melt. The proposed invention is aimed at creation of such plant which will improve strength, chemical and thermal stability of produced fibers by way of creating conditions near working aperture that will decrease the quantity of external impurities in the flow and allow obtaining of the melt, which is homogenous in terms of composition and temperature, in said zone of the plant. It is attained by means of adjustable damper installed at the entrance of the transition chamber, which does allow upper part of the melt flow (i.e. foam) to pass to the working aperture, and by means of the threshold installed below the adjustable damper, which does not allow lower part of the melt containing heavy unmelted rock particles to pass to the transition chamber. This significantly reduces the possibility of formation of stress concentrators in produced fiber and also the draw dies clogging.

    摘要: Method and apparatus for producing chopped rock fibers, such as basalt. A furnace is preferably used to melt rocks, and a drawing assembly is used to draw the melted rocks into fibers. Prior to chopping the fibers to selected lengths, a preconditioning assembly operates to induce mechanical defects in the drawn fibers. Preferably, the preconditioning assembly comprises a shock cooling stage and/or a fiber twisting stage. The shock cooling stage significantly reduces the temperature of the drawn fibers, such as by the application of a stream of fluid such as water or steam to the drawn fibers. Additionally or alternatively, the shock cooling stage preferably comprises a liquid coolant bath through which the drawn fibers pass. The fiber twisting stage preferably utilizes a twisting assembly such as a roller to induce a torsional force upon the drawn fibers to continuously twist the fibers about an axis thereof.

    摘要: The invention relates to a method and a plant for producing fibers from molten rocks such as basalt, diabase, amphibolite, andesite, dacite, granite and rhyolite. The inventive method involves rock crushing for producing grains of a specified size, charging the crushed rock into a melting zone and drawing fibers from the melt. The melting zone is extended along the vertical axis. The sized grains successively fall under gravity into the melting zone and the fibers are drawn from each sized grain melt. The drop rate of each sized grain into the melting zone is limited by the upward flow of a hot gas-air mixture. The plant comprises a rock crushing device and melting device with a melting zone whose outlet is connected to the discharge orifice with a bushing assembly and a device for fiber winding at the output. The plant includes a funnel at the outlet of the rock crushing device rotatable around the vertical axis.
