Method for automatically grabbing blast furnace water slag through travelling crane

Abstract

The invention discloses a method for automatically grabbing blast furnace water slag through a travelling crane. The method comprises the following steps that (1) an automatic slag grabbing system isbuilt up; (2) parameters are set; and (3) slag grabbing is achieved, wherein when a grab bucket is in contact with the water slag in one slag flushing pool, a controller records the numerical value ofan absolute value encoder at this moment, the height, namely, the height of the water slag in grabbing units, of the bottom of the grab bucket, is obtained, the water slag is grabbed, the controllercontrols the grabbing bucket to sequentially grab the water slag in the k*j grabbing units in the slag flushing unit, operation is carried out by multiple turns till all the water slag in the slag flushing pool is grabbed, and then the water slag in the next slag flushing pool is grabbed. According to the method, a weight sensor is arranged on a steel wire rope, the absolute value encoder is arranged on a winding drum, the multiple slag flushing pools are numbered, each slag flushing pool is divided into the k*j grabbing units, and multi-turn slag grabbing is carried out on each slag flushingpool till all the slag is grabbed; and efficiency is high, manual operation is not needed, manpower is saved, and personal injuries are reduced.

Description

technical field [0001] The invention relates to a method for automatically grabbing blast furnace slag by driving a vehicle. Background technique [0002] Blast furnace slag is an indispensable by-product in the ironmaking process. The slag discharge temperature is about 1450 degrees and contains rich sensible heat resources. Blast furnace slag is currently a treatment method commonly used by ironmaking enterprises. The biggest advantage of this method is Blast furnace slag can be recycled and utilized very well. The resource utilization rate of blast furnace slag in my country has reached more than 95%. It is usually used as cement raw material. At the same time, blast furnace slag can be used as cement raw material to reduce the decomposition of limestone in the cement production process, thereby reducing carbon dioxide emissions. . [0003] The slag grabbing crane, as the equipment for transporting blast furnace slag washing water, plays an important role in the entire pro...
