Abstract

The invention provides a blast-furnace molten slag deslagging amount online detection device and method. The device comprises a slag amount weighing device, a gravity sensor, a data collection systemand a data processing and displaying system; the slag amount weighing device is arranged on the tail end of a blast furnace slagging channel and used for weighing the deslagging weight in real time, the slag amount weighing device is provided with a slag trough work lining, the gravity sensor is arranged on a concrete or steel structure platform, the slag amount weighing device is arranged on andhangs on the gravity sensor, the data collection system is used for collecting variable weighing data of the slag amount weighing device in real time, the data processing and displaying system is usedfor calculating and displaying the blast-furnace deslagging amount and the deslagging flow value in real time according to blast-furnace molten slag deslagging variable weight data, through real-timedetecting of blast-furnace deslagging weight changes, the blast-furnace molten slag deslagging amount and the instant flow are calculated, the device and method can be suitable for online detection needs of blast furnace deslagging amount adjusting under the blast furnace complex process, the reliable judgment basis is provided for ensuring stable direct motion of a blast furnace, meanwhile, thebasis is provided for subsequent slag flushing system water amount adjusting, and the furnace slag processing system power consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of blast furnace smelting, in particular to an on-line detection device and method for blast furnace slag output. Background technique [0002] Blast furnace ironmaking is a complex system engineering. Due to the harsh internal environment of high temperature, high pressure and chemical erosion in the blast furnace hearth, the parameters for the flow state of slag and iron in the hearth can only be obtained by indirect means. The amount of slag per ton of pig iron smelted by blast furnace is an important parameter of blast furnace operation. Its amount reflects the grade of ore and fuel consumption. It is difficult to measure in actual production and can only be obtained by theoretical calculation. Due to the influence of chemical composition error, the calculated slag amount has a large error. [0003] However, there are four methods for detecting the slag output of blast furnace slag: the first method use...
