Description
A kind of being installed on the rolling service line, the annular spray formula cooling that directly utilizes the stocking waste heat to heat-treat
The invention belongs to stocking and roll back waste heat heat-treating apparatus.
Existing cooling
Nozzle and the angle between the nozzle chamber big, be difficult for processing, water cooling tube connecting joint, water cooling tube are screwed connections, and be not quick detachable, increases break down time.Garden of the present invention ring jet-type cooling
The little easy processing of angle between nozzle and the nozzle chamber.Water cooling tube connecting joint, water cooling tube are used instead to spend slightly to connect to be convenient to dismantle and are saved break down time.
Annular spray formula cooling of the present invention
By nozzle (1), water inlet pipe (2), nozzle chamber (3), and water-cooled pipe joint (4), water cooling tube (5) and back water pipe (6) are formed, and it is characterized in that forming between nozzle (1) and nozzle chamber (3) 14-15 ° angle.Nozzle, water inlet pipe, nozzle is used thread connection between the chamber.Water-cooled pipe joint (4) utilizes degree connection slightly between water cooling tube (5) and the back water pipe (6), with the assurance convenient disassembly, and be convenient to the processing accident.
Water-cooled pipe joint (4), water cooling tube (5) and back water pipe (6) constitute 2.5～3.5 meters length, to guarantee that steel are in cooling
In carry out the heat exchange of fullest.
The objective of the invention is to make surface of reinforced bar to carry out uniform hardening, for example, can make the yield strength of 16 millimeters reinforcing bars of 20MnSi diameter improve 10 kgf/millimeters

Claims (4)
1, a kind of annular spray cooler is by nozzle (1), water inlet pipe (2), nozzle chamber (3), and water-cooled pipe joint (4), water cooling tube (5) and back water pipe (6) are formed, and it is characterized in that nozzle, water inlet pipe, nozzle use thread connection between the chamber.
2, by the described cooling of claim 1
Form 14 °～25 ° angle between its nozzle (1) and nozzle chamber (3), roll to high velocity flow to guarantee that low-pressure water becomes.
3, by the described cooling of claim 1
, water-cooled pipe joint (4), water cooling tube (5) utilizes slightly with back water pipe (6) that degree is connected.
4, by the described cooling of claim 1
, water-cooled pipe joint (4) has the length of 2.5-3.5 rice between back water pipe (6), to guarantee that reinforcing bar is in cooling
In carry out the heat exchange of fullest.
