Description
Technical field
The present invention relates to the cooling technology field of steel rolling process, be 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 the roller-way, rotate forward transportation by table roller, the number formulary Fans is upwards dried to coil under the roller-way, wire rod is forced quenching, by changing the number of units of blowing blower fan, 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 standard type cooling, slowly type cooling and delaying type cooling according to the needs of different steel grades.The needs that have are forced the steel grade of cooling, and the below blowing forces cooling sometimes not reach the cooling velocity requirement.Particularly the blower fan cooling capacity does not usually reach product to the cooling velocity requirement in the high-carbon steel production, 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 under lower temperature.Cooling can make particularly hypereutectoid steel sorbite rate raising of high-carbon steel fast, improves its reduction of area, and drawing property is improved, and avoids simultaneously occurring in the metallographic structure network cementite and martensite to ensure the material extension property.Network cementite control is wherein the most difficult, and cooling hastened before directly way improved phase transformation exactly, allowed metal in a disguised form finish 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 objective of the invention is to propose 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.
