摘要： A system for melting materials during the production of a glass or ceramic material is disclosed. A method for melting materials during the production of a glass or ceramic material is also disclosed. The system comprises a melt tank having an interior with a width and a length; and an electrode array comprising a plurality of elongate electrodes each extending at least partially across the width of the interior of the melt tank in a direction substantially perpendicular to the length of the interior of the melt tank. Each electrode within the electrode array is spaced apart from an adjacent electrode within the electrode array by from about 5 mm to 100 mm. The electrode array is configured such that during a heating operation, current flows between adjacent electrodes within the electrode array, such that heat is radiated from the electrodes to materials located within the interior of the melt tank.

摘要： The present invention refers to a method for producing a glass body with high silicic-acid content by drawing a softened glass mass from an elongated, substantially cylindrical crucible in that SiO2 granules are supplied from above into the crucible, the SiO2 granules are heated to a softening temperature, so that the softened glass mass which comprises a melt surface is formed, the softened glass mass is drawn off via a bottom opening of the crucible so as to form a glass strand, and the glass strand is cut to length to obtain the glass body, wherein due to the supply of the SiO2 granules a bulk heap is formed that covers the melt surface in part while leaving a melt edge, and wherein the melt surface is optically detected. To improve the fusion behavior of the granules and to suppress or altogether prevent the formation of a sinter crust, it is suggested according to the invention that during the optical detection of the melt surface the width of at least a sub-section of the melt edge is determined consecutively and is set to a value within a target width range through the supply rate of the SiO2 granules.

摘要： A vacuum melting furnace for infrared glass, includes an upper furnace body and a lower furnace body that can be connected with each other or isolated from each other. Vacuum melting of the infrared glass is achieved in the upper furnace body wherein the influence of water in the environment is eliminated. The vacuum negative pressure environments can promote separation of hydroxyl in the structure, which achieves removing of hydroxyl in the glass, and then discharging of the molten infrared glass is conducted at atmospheric pressure in the lower furnace body. By using the vacuum melting furnace for infrared glass, infrared glass with good spectrum transmission performance can be obtained with improved property stability and optical homogeneity, which facilitates the preparation and molding of large sized and special-shaped infrared glass products.

摘要： A waste vitrification apparatus (10) having rotatable mixer impeller (16) functioning as a shaft electrode (60) and metallic vessel (14) functioning as a vessel electrode (62). A stream (12) of waste material and vitrifiable material are mixed and melted in the vessel (14) for vitrification. The waste vitrification method converts a feed stream (12) by mixing the feed stream into a glass melt (13) and melting glass batch of the feed stream (12) to form a foamy mass. The stream is dispersed by the impeller (16) to form a foam which is then densified in a settling zone (22), recovered through a spout (24) and solidified in storage containers. An adjuster adjusts the location of the mixing impeller (16) in the vessel (14) to change the depth of the settling zone (22). The impeller (16) is mounted on a drive shaft (18) having a recirculating coolant flow.

摘要： A method for producing an elongated composite glass body by melting at least two starting materials of different material compositions, feeding the starting materials to a drawing die disposed at the bottom of an externally heated melting crucible, and continuously drawing the melts vertically out of the drawing die to form a composite body laminated transverse to the drawing direction. To provide an interface free from impurities between the starting materials in the composite body and to enable the path of the interface to be freely shaped, the starting materials are fed in particle form continuously to a single melting crucible and heaped therein to form a preformed body in which one starting material lies directly next to the other starting material forming an interface line therebetween that extends substantially vertically and parallel to the drawing direction.

摘要： For melting an inorganic fiber which is mixed with an organic substance, the inorganic fiber material and organic substance are heated in a furnace to a temperature sufficient for the organic material to combust, and sufficient oxygen enriched gas is fed to the furnace that the combustion of the organic substance produces sufficient heat to melt the inorganic material. The oxygen enriched gas is preferably oxygen enriched air having an oxygen content of at least 40% by volume. It should be fed in sufficient quantity to heat material having an adiabatic temperature of at least 850.degree. C., and preferably 1200.degree. C. which permits the melted inorganic material to freely flow out of the furnace. The oxygen enriched gas is preferably fed to a location adjacent a boundary layer between the melted material and unmelted material on the top thereof.

摘要： An electric melting furnace for solidifying highly radioactive waste in glass has a melting cavity made of a non-conductive refractory and adapted to melt a raw material consisting of highly radioactive waste and a glass material by passing a current between horizontally opposing electrodes, and to extract the molten glass material through a plurality of outlet ports at a bottom portion of the furnace, the melting cavity being partitioned by a non-conductive partitioning refractory provided on the bottom portion of the furnace between outflow ports. Since the furnace is so structured that the melting cavity is partitioned by the non-electrically conductive refractory, all current lines connecting the pair of electrodes for melting the highly radioactive waste, which contains elements of the platinum group, detour around the partitioning refractory. According to the current line distribution produced, it is just as if the electrodes were located on the upper side of the refractory as seen from each section of the partitioned melting cavity. This makes it possible to prevent the current flowing between the electrodes from concentrating in deposits which collect at the furnace bottom and contain the platinum-group elements in high concentration. It is also possible to reduce melting cavity depth in comparison with the melt surface area and inter-electrode distance.
