Embodiment Construction

[0014] As shown in the figure, the double-hole rotary refractory spray gun includes a gun body; The blue plate 3; the central nozzle 1 is set in the protective tube 2; the refractory material layer 4 is placed outside the protective tube 2; in the refractory material layer 4, a skeleton 5 is fixed outside the protective tube 2; The lower end of the central nozzle 1 is provided with two tail nozzles 6 ; the output power of the rotating mechanism 7 is transmitted to the flange 3 .

[0015] In order to protect the structure of the bottom of the gun body and prolong the service life of the spray gun, the bottom of the gun body of the present invention can be designed to be hemispherical.

[0016] The gun body of the present invention can be fixed with rotating stirring blades 8, and the number of the rotating stirring blades 8 is four, and they are evenly distributed on the outer wall of the gun body.

[0017] The heat insulation layer 9 fixedly arranged on the outer wall of the ...

Abstract

The invention belongs to the field of molten iron desulfuration equipment, and in particular relates to a double-hole rotary fireproof spray gun. The double-hole rotary fireproof spray gun comprises a gun body, wherein the gun body comprises a central spray pipe (1), a protective pipe (2), a fireproof material layer (4), a rotating mechanism (7) and a flange plate (3) fixedly connected with the central spray pipe (1); the central spray pipe (1) is sleeved in the protective pipe (2); the fireproof material layer (4) is arranged outside the protective pipe (2); in the fireproof material layer (4), a framework (5) is fixed outside the protective pipe (2); the lower end of the central spray pipe (1) is provided with two tail jet nozzles (6); the power output by the rotating mechanism (7) is transmitted to the flange plate (3); and the bottom end of the gun body is of a semi-spherical structure. The double-hole rotary fireproof spray gun is simple in structure, good in effect of mixing a desulfurizing agent and molten iron and low in splashing strength.

Description

technical field [0001] The invention belongs to the field of molten iron desulfurization equipment, in particular to a double-hole rotary fire-resistant spray gun. Background technique [0002] Spray metallurgy usually refers to the fixed injection method widely used in industry: the spray gun is in a static state when spraying from the furnace bottom, furnace wall and furnace roof to the molten pool. When the lance blows upward from the bottom of the furnace, the fixed injection method is the only way, that is, the lance needs to be fixed in the refractory layer of the bottom of the furnace. When the spray gun is inserted into the injection from the furnace wall, it is generally in a static state. In the same water model test, compared with the fixed spray gun, it was found that the rotating spray gun made the bubbles smaller and the floating speed slower. The mass transfer coefficient between gas and liquid is CO 2 And NaOH absorption measurement, it is found that the a...
