Problems solved by technology

Among the tuyere components, the tuyere sleeve closest to the furnace is very easy to burn out and needs to be replaced frequently, especially in the later period of the furnace, the replacement is very frequent
[0003] Depending on the size of the furnace capacity, the blast furnace contains several to dozens of tuyeres. Therefore, the number of small tuyere sets that need to be replaced every time the blast furnace is shut down is large, and the workload is large; In order to achieve the effect of sealing, and due to the high temperature and thermal stress, it is extremely difficult to remove the small tuyere sleeve from the middle sleeve, the work is difficult and time-consuming

Abstract

The invention discloses a disassembling mechanism for a tuyere small sleeve. The disassembling mechanism comprises a push rod device, a first hook claw and a second hook claw which are installed at the head part of the push rod device, and an elastic part for connecting the first hook claw and the second hook claw, wherein the two ends of the elastic part are respectively fixed with the first hook claw and the second hook claw; the first hook claw and the second hook claw are respectively hinged with the push rod device by a hinge; two sharp-angled reverse hooks used for hooking the tuyere small sleeve are respectively arranged at the ends, far away from the push rod device, of the first hook claw and the second hook claw. The disassembling mechanism for the tuyere small sleeve is simple and reliable in structure and convenient to use.

Description

technical field [0001] The invention relates to the technical field of metallurgical equipment, in particular to a dismantling mechanism and a dismantling method of a small tuyere sleeve. Background technique [0002] During the smelting process of the ironmaking blast furnace, hot air at about 1100°C needs to be blown to the blast furnace through multiple tuyeres. Among the tuyere components, the tuyere sleeve closest to the furnace is very easy to burn out and needs to be replaced frequently, especially in the later period of the furnace, the replacement is very frequent. [0003] Depending on the size of the furnace capacity, the blast furnace contains several to dozens of tuyeres. Therefore, the number of small tuyere sets that need to be replaced every time the blast furnace is shut down is large, and the workload is large; In order to achieve the effect of sealing, and due to the effect of high temperature and thermal stress, it is extremely difficult to remove the sm...
