Description
Technical field
The utility model relates to the cooling technology field of steel rolling process, is specifically related to the gas-mist cooling device on a kind of rod-rolling mill Stelmor cooling line.
Background technology
At present, high-speed rod rolling, Laying head with the coil lopping after flat telling on the stelmor conveyor roller, be tiled in the coil on roller-way, rotate transportation forward by table roller, under roller-way, the number formulary Fans is upwards dried to coil, wire rod is forced quenching, by the dry number of units of blower fan of change, the wind turbine allocation of the amount of air, stay-warm case is opened quantity and the roller table speed different set changes the intensity of cooling of coil, thereby makes different size, steel grade wire product obtain required tissue and performance.Methods for cooling is divided into according to the needs of different steel grades that standard type is cooling, slow type is cooling and delaying type is cooling.Some needs are forced cooling steel grade, and the cooling cooling velocity requirement that sometimes do not reach is forced in the below blowing.Particularly in high-carbon steel production, the blower fan cooling capacity does not usually reach product to the cooling velocity requirement, for carbon steel wire rod with high is obtained near the lead bath handling property, require the higher laying temperature of needs and cooling velocity faster according to C curve, the cooling velocity of this technology controlling and process can make the degree of supercooling of austenite decomposition increase like this, continuous cooling transformation (CCT) curve moves to the lower right, makes thicker austenite crystal change pearlitic transformation into and carries out at lower temperature.Fast cooling can make high-carbon steel particularly hypereutectoid steel sorbite rate improve, improve its reduction of area, drawing property is improved, and avoids simultaneously occurring in metallographic structure network cementite and martensite to ensure the material extension property.It is wherein the most difficult that network cementite is controlled, and directly way improves front cooling the hastening of phase transformation exactly, allows metal in a disguised form complete rapidly, and the net time is separated out and connected into to the compression cementite, and it is crucial improving the blower fan cooling capacity.
Summary of the invention
In view of the defective that above-mentioned prior art exists, the purpose of this utility model is that proposition is a kind of simple in structure, easy to operate, can improve the wire rod air-cooled line gas-mist cooling device of blower fan cooling capacity.
The purpose of this utility model, to be achieved by the following technical programs: a kind of wire rod air-cooled line gas-mist cooling device, comprise blower fan, it is characterized in that: described blower fan air blast cooling fore-end is equipped with fog-cooling, described fog-cooling comprises nozzle, the end of described nozzle is connected to the compressed air input pipe by air inlet pipe, and the below of described nozzle is connected to coolant intake pipe by water inlet pipe.
The technical scheme that the utility model further limits is: aforesaid wire rod air-cooled line gas-mist cooling device, described nozzle at right angle setting both is threaded on the nozzle connecting plate.
Further, aforesaid wire rod air-cooled line gas-mist cooling device, described metal hose end is equipped with snap joint.
Further, aforesaid wire rod air-cooled line gas-mist cooling device, described nozzle up and down or the adjusting angle of left and right be 0 ° ~ 180 °.
The utility model, its outstanding effect is: the utility model can effectively improve the steel cooling velocity, improves the steel reduction of area, effectively reduces the steel surface scale, can reduce scale on surface and generate, and the acid consumption when improving secondary operations is improved surface quality.Can improve tensile strength and yield strength for screw-thread steel, can reduce environment temperature, improve operating environment.And the utility model is simple in structure, and is easy to operate, and production cost drops into low.
Following constipation closes the embodiment accompanying drawing, the specific embodiment of the present utility model is described in further detail, so that technical solutions of the utility model are easier to understand, grasp.
Description of drawings
Fig. 1 is the utility model structural representation.
The specific embodiment
The wire rod air-cooled line gas-mist cooling device that the present embodiment provides, structure as shown in the figure, comprise blower fan, wherein the air blast cooling fore-end of blower fan is equipped with fog-cooling, this fog-cooling comprises nozzle 1, and nozzle-end is provided with the external screw thread screw thread, and the vertical spinning of this nozzle both is threaded on the nozzle connecting plate 2 that is provided with the internal thread screw thread.Simultaneously, the end of nozzle is connected to compressed air input pipe 5 by air inlet pipe 4, and the below of nozzle is connected to coolant intake pipe 7 by water inlet pipe 6.And at water inlet pipe and air inlet pipe two ends, pipe joint 3 is installed.
Operation principle of the present utility model is: cooling water is by nozzle below access, and compressed air is accessed by nozzle-end, and the spray pattern of nozzle is that cavity atomizes outward, simultaneously, the head of nozzle is hemispherical, and has vertical masonry joint, atomizing is more abundant like this, and projected area is larger.The aerosol of atomizing is brought into blower fan, reaches wire surface with the blower fan blowing.Nozzle quantity of the present utility model can be according to cooling needs configuration, to reach necessary cooling requirement.Simultaneously, be designed with screw thread outside nozzle, make nozzle be assemblied in fixedly place.Cooling water and compressed air pressure are not less than 2.5Mp.
The utility model can effectively improve the steel cooling velocity, improves the steel reduction of area, effectively reduces the steel surface scale, can reduce scale on surface and generate, and the acid consumption when improving secondary operations is improved surface quality.Can improve tensile strength and yield strength for screw-thread steel, can reduce environment temperature, improve operating environment.And the utility model is simple in structure, and is easy to operate, and production cost drops into low.
