High titanium slag smelting emergency accident sand pool

Technical Field

The utility model belongs to the technical field of high titanium slag smelting, and particularly relates to a high titanium slag smelting emergency accident sand pool.

Background

In the high titanium slag smelting process of the electric furnace, because high-temperature smelting is used in the electric arc furnace, the temperature in the electric furnace is not equal to 1800 ℃, and because the electric furnace is in long-term production operation, the risk of high-temperature burning-through exists on the furnace wall, and the condition that the slag and iron can not be blocked due to discharge of various factors such as overhigh temperature, material blocking quality problems and the like in the discharging process of the slag and iron exists. Therefore, an emergency sand pool is usually arranged below the smelting furnace for accommodating high-temperature furnace burden leaked out of the furnace, so that the accident loss is reduced.

The current is in the middle of will leaking high temperature furnace charge drainage to emergent accident sand pool usually, the iron that solidifies in the sand pool of emergency accident is cleared up, nevertheless it is longer because of the flow behind the sand pool of emergency accident that the high temperature fuse-element furnace charge flows into, the high temperature fuse-element furnace charge temperature of outflow reduces, mobility weakens greatly and leads to the enrichment of high temperature fuse-element furnace charge to be close to furnace body and building factory building one side, it is thick to lead to the fact to be close to furnace body and factory building one side to pile up in the sand pool of emergency accident, at the in-process of clearing up the sand pool high temperature fuse-element furnace charge of emergency accident, because of the iron plate is thick and receive the influence increase clearance degree of difficulty of furnace body and factory building, reduce the sand pool of emergency accident and clear up iron efficiency.
