Description
Technical field
The utility model relates to a kind of water-cooled nozzle, relates in particular to a kind of high-efficiency water cooling nozzle that is applicable in rod, the wire water-cooled device.
Background technology
Water cooling plant is to force cooling and online heat treated equipment for the rod of the high temperature after rolling, wire rod, its principle is to cool off fast under austenitic state after utilizing rod, wire rolling, rod, wire surface are quenched into martensite, emit waste heat by its heart section subsequently and carry out self tempering, improve intensity and the plasticity of rod, wire rod, improve toughness, thereby obtain good comprehensive mechanical property.
When water-cooled is processed after utilizing water cooling plant that rolled piece is rolled, when cooling water is met red-hot rolled piece surface, can be subject to from the fast repulsive interaction of the steam blanket of the expansion of generation of rolled piece surface, and the direction of motion of change cooling water flow, thereby the action effect of reduction cooling water.
Therefore, the pressure of water cooling plant cooling water in cooling procedure and flow are two principal elements that affect the rolled piece cooling effect.And the structure of water-cooled nozzle directly affects the mode of jet of cooling water and the flow of cooling water in the water cooling plant, is the critical component in rod, the wire water-cooled device.
At first, the structure influence of water-cooled nozzle the pressure distribution of cooling water.The jet angle of water-cooled nozzle jet is a key factor that determines the water-cooled nozzle cooling effect, jet angle hour, the cooling water fluid is even in the section VELOCITY DISTRIBUTION of body porch, and during near the rolled piece surface, cooling water fluid speed is larger, fluid impact power is large, easy rupture of membranes, still, jet angle hour, the conference of fluid impact power cause rolled piece to be impacted and in water cooling plant play, cause the rolled piece interior tissue to occur bad; When jet angle was large, vertical component was larger, also was beneficial to rupture of membranes, but when jet angle was large, inhomogeneous cooling was even.
Secondly, the temperature of rolled piece reduces will come balance with the temperature rise of water, so the flow of cooling water can affect the cooling velocity of rolled piece.
In the prior art, the mode of jet of traditional water-cooled nozzle has two kinds of annular convergence seam and holes.Wherein, adopt hole to carry out the water-cooled nozzle of jet, when the hole ejection of current from nozzle, strengthen the injection kinetic energy of stream thigh, can effectively destroy the steam blanket on rolled piece surface, heat exchanger effectiveness is high.The jet hole forms certain angle with the rolled piece traffic direction, has jet angle hour, and cooling water fluid speed is larger, and fluid impact power is large, rolled piece impacted and in water cooling plant play, it is bad that the rolled piece interior tissue occurs, when jet angle is large.
