At present, a steel pipe induction quenching cooling mode generally adopts a fixed low-pressure external shower device, and the cooling capacity of the steel pipe induction quenching cooling mode is limited. For thick-wall steel pipes or steel pipes with poor hardenability, the cooling rate cannot be effectively increased even if the flow rate of the outer spray water is increased, so that a mode of combining inner spray and outer spray is required. However, the existing internal spraying cooling device has poor cooling effect, internal spraying water flows from one end of the inner bottom of the steel pipe to the other end, and cannot be uniformly sprayed to the inner surface, so that the difference of cooling rates of different positions of the steel pipe is large, uneven structures of the inner wall and the outer wall are caused, and even the problems of unqualified performance or insufficient strength allowance and the like are also caused. In addition, since the steel pipe is always in a rotating state during quenching, how the spray head of the internal water spray device is fixed inside the steel pipe also becomes a problem.
So no effective quenching cooling mode exists at present.

Detailed Description
Referring to fig. 1 and 2, the utility model relates to an internal spray cooling device for steel pipe induction quenching, which comprises two sections of roller tables 1, wherein the roller tables 1 are controlled to act through a row of driving rollers 2, and the driving rollers 2 are controlled to rotate positively and reversely through a motor, so that the roller tables 1 can be driven positively or reversely. The steel pipe 11 is placed on the roller way 1, and the distance between the two sections of roller ways 1 is far smaller than the length of the steel pipe 11, so that the steel pipe 11 can be smoothly conveyed from the front section of roller way to the rear section of roller way.
The middle of the two sections of roller tables 1 is provided with a spray groove 3, and the side wall of the spray groove 3 is higher than the front side and the rear side at the left side and the right side, so that the steel pipe 11 can conveniently pass through from front to back. A plurality of outer spray pipes 4 are inserted into the side wall of the spray tank 3, the outer spray pipes 4 are positioned at the left side and the right side of the inner wall of the spray tank 3, and a gap is reserved between the left outer spray pipe 4 and the right outer spray pipe 4 to allow the steel pipe 11 to pass through.
