Embodiment Construction

[0047] Attached below Figure 1-4 A detection device and detection method for the interface between matte and slag in a side-blowing smelting furnace of the present invention are described in detail.

[0048] The theoretical basis of the present invention is based on the use experience of the air blowing type liquid level / interface instrument, and the air supply steady flow control device (valve group) of the side blowing spray gun provides the air source carrier for pressure transmission. According to the principle of static pressure transfer (Pascal's law), the pressure at a point A in the liquid is:

[0049] P=ρ·h

[0050] It should be noted that the gravitational acceleration g is omitted in the above formula and the following calculation formula, because g=9.8m / s 2 , is a constant; among them, P is the pressure at a certain point A in the liquid, ρ is the density of the liquid, and h is the height at a certain point A from the liquid surface. Assuming that ρ is known, ...

Description

technical field [0001] The invention relates to the technical field of metallurgical auxiliary detection, in particular to a detection device capable of realizing the interface between matte and slag in a side-blown smelting furnace and a detection method thereof. Background technique [0002] Oxygen-enriched side-blown smelting furnace is a relatively advanced non-ferrous metallurgical furnace. The control of the interface between molten matte and smelting slag during the metallurgical process of side-blown smelting furnace is one of the important control indicators for the safe and continuous operation of the furnace. At present, the detection of the interface between the matte and the smelting slag in the side-blown smelting furnace mainly relies on the detection of the winch probe. Features that are conducive to operation. How to accurately measure the interface between molten matte and smelting slag in the side-blowing smelting furnace in real time is an important link...
