Specific embodiment
As shown in Figs 1-4, a water quenching device for the heat treatment of high speed hot rolling finer wire, it is characterised in that: including
Cooler bin 1 is equipped with cooling component 2 in cooler bin 1, and steel wire 14 runs through cooling component 2, and cooling component 2 is welded by cooling holder 3
It connects and is fixed in cooler bin 1, cooling component 2 is assembled into the cooling nozzles 5 in cooling tube 7 by the positioning mold core 4, three for being set to end
Composition, cooling tube 7 are provided with gap 6, and cooling nozzles 5 are by air inlet pipe 8, water inlet pipe 9, air cavity 10, pulverizer plate 11, gas-vapor mix chamber
12, spout 13 forms, and is divided into air cavity 10 and 12 two cavitys of gas-vapor mix chamber in cooling nozzles 5, connects air inlet pipe on air cavity 10
8, water inlet pipe 9 is connected on gas-vapor mix chamber 12, middle part is equipped with spout 13 around steel wire 14, between air cavity 10 and gas-vapor mix chamber 12
It is separated by pulverizer plate 11.
There are three cooler bin 1 is set.
Technical principle: the present invention carries out Cooling Quenching to steel wire using recirculated cooling water, in cooling procedure, has cooling
Speed is fast, and cooling velocity reaches 400 degree per second, and water is a kind of safe and efficient quenching medium, and the specific heat capacity of water is, water
Heat of vaporization is.It is water mist after the vaporization of water without harmful substance, so water is a kind of ideal cooling medium, root is it was found that water
Vaporization undergo three kinds of states, water will form bubble after contacting with steel wire, the barrier of bubble affects the ability that water cools down, and gas
Highly endothermic ability is had after bubble rupture, for this cooling characteristic of water, present invention employs the mode of water, gas combination cooling,
By adjusting the mixed proportion and pressure size of water, two phase medium of gas, the cooling capacity for adjusting water quenching can be realized, managed
The quenching effect thought.
Air inlet pipe 8 above cooling nozzles 5 is connected with compressed air, admission pressure 0.2Mpa, water inlet pipe 9 and water pump
Recirculated cooling water be connected, intake pressure 0.2Mpa can individually adjust admission pressure or influent pressure according to cooling requirement
Power can also adjust air inlet and intake pressure simultaneously.Into the compressed air of air cavity, gas-vapor mix chamber, pressure are pressed by porous plate
So that water is become gas liquid mixture in contracting air injection, after this gas-liquid two-phase mixture is sprayed by spout, splits into water
Misty liquid grain is contacted with steel wire, and the particle of this liquid grain is more tiny, and cooling effect is better.
Advantages of the present invention: carrying out primary atomization to aqueous medium using diffuser of multiple holes, is situated between by spout to gas-liquid mixed
Matter carries out secondary-atomizing, keeps the particle of cooling medium smaller, cooling efficiency is higher, and cooling velocity makes up to 800 degree per second or more
The grain size of steel wire is thinner, and sorbite rate reaches 92% or more, and tension dials intensity and reaches 1200N, and elongation percentage reaches 12%, reduction of area
Up to 95.7%, water mist impact makes steel wire surface cool down rapidly, reduces the formation of oxide skin, and keep oxide layer more shallow, more carefully,
It is easy to remove.
