Embodiment Construction

[0011] The batch material is added from the flame space (1) to the glass 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 higher load current and the self-energization generate heat, so that the batch material melts and the molten glass is clarified. The molten glass is further clarified and homogenized through the lower pool (3) of the melting tank, and the clarified and homogenized glass liquid enters the forming material channel through the flow hole (4) and the ascending channel (5). The starting molybdenum electrode (7) is only used when the full electric furnace is started for charging, and only a small amount of electric load is added to the 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 it is of...

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 furnace technology capable of melting high-quality high-borosilicate instrument glass. Background technique [0002] At present, the all-electric melting furnace for high borosilicate instrument glass is triangular or quadrangular. This furnace shape limits the reasonable arrangement of the melting electrodes, so that the internal heat distribution of the molten glass in the furnace is uneven; and this furnace shape leads to "dead corners" of the molten glass. many. Moreover, the depth of the existing all-electric furnace for high borosilicate instrument glass causes the clarification and homogenization time of the glass to be too short. The above factors make it difficult to improve the quality of molten glass. Summary of the invention [0003] In order to overcome the problems of uneven heat distribution in the molten glass in the existing all-electric borosilicate instrument glass furnace, many "dead corners" of ...
