Embodiment Construction

[0018] The present invention will be further described in detail with reference to the accompanying drawings and embodiments.

[0019] Such as figure 1 and figure 2 As shown, the method for measuring the matte liquid level in the oxygen-enriched bottom-blown furnace in the present embodiment may further comprise the steps:

[0020] Step 1, making a measuring rod, the measuring rod includes a measuring section AC, an operating section BA and an angle adjustment section BD, the measuring section AC, the operating section BA and the angle adjustment section BD are in the same plane, and the measuring section AC and the angle adjustment section The length of the section BD is the same, and the angle between the angle adjustment section BD and the operation section BA and the angle between the operation section BA and the measurement section AC are both α;

[0021] Step 2. Align the measurement section AC with the slag mouth of the oxygen-enriched bottom-blown furnace upward, an...

Abstract

The invention provides a method for a measuring copper matte liquid level in an oxygen-rich bottom blowing furnace to solve the problems of an existing method that workers are liable to be burned, potential safety hazards exist, the measuring process is complex, and accuracy is low, and belongs to the field of oxygen-rich bottom blowing furnace copper smelting operation. Measuring is conducted with a measuring rod at a cinder notch of the oxygen-rich bottom blowing furnace. The characteristics of relative quiescence of the liquid level in the sediment zone at the cinder notch in the furnace are fully utilized. A measuring opening being blocked by splashing materials is avoided, and the safety factor is relatively high. The method can be used for measuring at any time in the working time period of slag discharging, and the measuring time is flexible. The bonding force between the copper matte and slag and the measuring rod is different so that the copper matte liquid level can be accurately measured, and therefore the copper matte liquid level in the oxygen-rich bottom blowing furnace can be better controlled, the slag release and copper discharge time can be reasonably arranged, better serve is provided for the next process, and an intuitive and referable basis is provided for practical production.

Description

technical field [0001] The invention relates to the technical field of copper smelting operation in an oxygen-enriched bottom-blown furnace, in particular to a method for measuring the liquid level of matte in an oxygen-enriched bottom-blown furnace. Background technique [0002] Oxygen-enriched bottom-blown furnace bath smelting is a new generation of copper smelting technology with independent intellectual property rights in my country. This method has the characteristics of low investment, strong adaptability of raw materials, and energy saving. The oxygen-enriched bottom-blown smelting furnace is a rotatable horizontal cylindrical furnace, which blows oxygen-enriched air into the molten pool through the oxygen lance at the lower part of the molten pool, so that the molten pool is in a strong stirring state. After the mixture in the furnace undergoes a series of physical and chemical changes in the reaction zone, the molten material flows toward the slag mouth and enters ...
