Embodiment Construction

[0012] The batch material is added from the flame space (1) to the glass liquid surface of the upper pool (2) of the melting pool and covers the entire liquid surface; the glass liquid is provided by six molybdenum melting main electrodes (8) evenly installed vertically on the transition brick (6) The large load current and self-energization generate heat, so that the batch material is melted and the molten glass is clarified. The molten glass is further clarified and homogenized through the lower tank (3) of the melting pool, and the clarified and homogenized molten glass enters the molding channel through the liquid hole (4) and the ascending channel (5). The start-up molybdenum electrode (7) is only used when starting and charging the all-electric furnace, and only a small amount of electric load is added to the start-up molybdenum electrode to supplement the heat taken away by the cooling water of the electrode water-cooling jacket during the operation of the furnace after ...

Abstract

A stepped hexagonal cold-top full-electric smelting furnace for smelting the high-boron silicon glass used for instrument is composed of flame space, smelting pool, liquid flowing hole, and lifting channel. Said smelting pool is composed of the hexagonal upper pool with large area, the tetrahexagonal lower pool with small area, and the transition bricks for connecting both pools. Six molybdenum electrodes are vertically installed to said transition bricks. Its advantage is uniform heat distribution.

Description

Technical field [0001] The invention relates to an all-electric melting furnace capable of melting high-quality borosilicate instrument glass. Background technique [0002] At present, the high borosilicate instrument glass all-electric melting furnace is triangular or quadrangular. This kind of furnace shape limits the reasonable arrangement of melting electrodes, so that the heat distribution inside the molten glass in the furnace is uneven; and this kind of furnace shape leads to "dead corners" of the molten glass many. Moreover, the depth of the existing high borosilicate instrument glass all-electric melting furnace pool is shallow, resulting in too short clarification and homogenization time of the glass liquid. The above factors cause the quality of molten glass to be difficult to improve. Contents of the invention [0003] In order to overcome the problems of uneven heat distribution of molten glass in the existing high borosilicate instrument glass all-electric ...
