Melt desulfurization turbine agitator

Abstract

The invention belongs to the field of hot metal pretreatment desulfurization equipment, and particularly relates to a melt desulfurization turbine agitator. A first hub (2) is arranged on the upper parts of agitating blades (1); a jet pipe (4) is arranged in the middle of an agitating shaft (3) in a sleeved manner; the exterior of the jet pipe (4) is sleeved with a cooling jacket (8); a distributor (9) is arranged at the bottoms of the jet pipe (4) and the cooling jacket (8); an annular cooling gas through groove (801) is formed in the top of the distributor (9); the inner wall of the coolingjacket (8) and the jet pipe (4) form a cooling gas channel (12); the bottom of the cooling jacket (8) is provided with air supply holes (802); the top of the distributor (9) is circumferentially provided with an exhaust grille (10); the air supply holes (802) communicate with the exhaust grille (10); an annular cooling cavity (201) is formed in the first hub (2); and the exhaust grille (10) communicates with the annular cooling cavity (201). The melt desulfurization turbine agitator is high in agitating power and high in desulfurization efficiency.

Description

technical field [0001] The invention belongs to the field of molten iron pretreatment desulfurization equipment, in particular to a melt desulfurization turbine agitator. Background technique [0002] With the rapid development of modern industrial production and science and technology, the requirements for steel quality are increasing day by day. For example, in order to avoid internal cracks in billets and obtain good surface quality, the sulfur content of ordinary steel is required to be less than 0.020%; in order to make structural steel have uniform mechanical properties, the sulfur content in steel is required to be less than 0.010%; in order to make oil and Natural gas pipelines, steels for petroleum refining equipment, steels for offshore oil production platforms, low-temperature steels, thick ship plate steels, and aviation steels have properties such as hydrogen-induced crack resistance, more uniform mechanical properties, and higher impact toughness. Silicon steel...

AI Technical Summary

Problems solved by technology

However, the existing KR method mechanical stirring device generally has a single direction of stirring force and insufficient stirring force, which will cause some desulfurization agents to float up into the slag without participating in desulfurization, and some desulfurization products are still in the molten iron due to insufficient floatation. To achieve the desulfurization effect, the stirring force is weak, resulting in slow desulfurization reaction speed and low desulfurization efficiency
