Description

Technical Field

[0001] The utility model relates to the technical field of slag water quenching, in particular to a slag water quenching device with controllable slag flushing. Background Art

[0002] Water-quenched slag is the abbreviation of water-quenched basic iron furnace slag. It is a granular slag with a rough and porous surface, light and brittle texture, and easy to break. In 1972, Nanhui paved a 500-meter-long wet-rolled water-quenched slag test road (instead of cement concrete) on the Shanghai-Nan Highway. The quality of use was good, but due to the shortage of water-quenched slag materials, it was not further promoted. Water-quenched slag is a method for treating slag from an ore-heating furnace. This method quenches the molten slag of the ore-heating furnace with water to obtain water slag. At present, when using the water quenching method to treat the slag of the electric arc furnace, the slag flushing pressure is difficult to control. If the pressure is too low, a large amount of foaming slag will be produced, which will clog the connectors, distributors and other equipment, and even explode in severe cases. If the pressure is too high, the water slag particle size is small, and it is easy to produce fine slag and cotton slag, causing part of it to clog the filter screen and reduce the drum filtering capacity, and part of it will pass through the filter screen and enter the hot water pool, thereby wearing out the slag flushing pump, hot water pump, underflow pump, pipelines and other equipment. In addition, when water quenching is performed, the water quenching aqueous solution and the molten slag liquid are easily exposed to the explosion and splashing effect due to the excessive temperature difference at the moment of contact, causing equipment damage and personal injury, and the operating environment is poor.
