Abstract
本实用新型涉及一种轧制无缝钢管时降温用的无缝钢管控冷控轧冷却水圈，其特征在于，设置有若干喷淋嘴的喷淋管绕水环轴线均匀设置构成笼式结构。所述的喷淋嘴轴线与垂直线有5°～20°夹角。与现有技术相比，本实用新型的有益效果是：控制无缝钢管在定径机前、后的轧制温度，有效避免冷却水滞留，并保证无缝钢管圆周方向冷却均匀，圆周方向上的强度一致，还可避免冷却水进到无缝钢管内部引起滞留。
The utility model relates to a cooling water ring for controlled cooling and rolling of seamless steel pipes used for cooling when rolling seamless steel pipes. . The axis of the spray nozzle has an included angle of 5°-20° with the vertical line. Compared with the prior art, the utility model has the beneficial effects of controlling the rolling temperature of the seamless steel pipe before and after the sizing machine, effectively avoiding the stagnation of cooling water, and ensuring uniform cooling of the seamless steel pipe in the circumferential direction. The strength is consistent, and it can also prevent the cooling water from entering the seamless steel pipe and causing stagnation.
Description
Technical field
The controlled rolling and controlled cooling device of cooling usefulness when the utility model relates to a kind of rolling seamless steel pipe.
Background technology
During rolling seamless steel pipe, because sizing mill begins rolling temperature and final rolling temperature can not effectively be controlled, cause steel pipe metal inside grain growth, thereby had a strong impact on every physical property of seamless steel pipe, make steel pipe after rolling because of the performance inconsistency lattice produce waste product, reduced the seamless steel pipe lumber recovery.The mode of present domestic implementation seamless steel pipe controlled rolling and cooling, behind the tandem mill winding arbor extraction press, add the cooling hydrosphere, in order to the forward and backward rolling temperature of control sizing mill, this cooling hydrosphere adopts the circumference closing form, cause cooling water to be deposited on the hydrosphere bottom, cause the first half and the latter half cooling degree varies of steel pipe to cause, thereby make steel pipe intensity on same circumferencial direction inconsistent.
Summary of the invention
The purpose of this utility model provides a kind of device of realizing the seamless pipe controlled rolling and controlled cooling, and this device can guarantee the cooling of seamless steel pipe circumferencial direction evenly, the intensity unanimity on the circumferencial direction.
The utility model is achieved through the following technical solutions:
A kind of device of realizing the seamless pipe controlled rolling and controlled cooling is characterized in that, the shower that is provided with some spray nozzles evenly is provided with the formation cage construction around the water ring axis.
Described spray nozzle axis and vertical line have 5 °～20 ° angles.
Compared with prior art, the beneficial effects of the utility model are: the control seamless steel pipe is in the forward and backward rolling temperature of sizing mill, effectively avoid cooling water to be detained, and guarantee the cooling of seamless steel pipe circumferencial direction evenly, intensity unanimity on the circumferencial direction also can be avoided cooling water to enter seamless steel pipe inside and cause delay.

Fig. 2 is the side view of Fig. 1.
1-water ring 2-shower 3-spray nozzle 4-steel pipe among the figure
The specific embodiment
Below in conjunction with accompanying drawing the specific embodiment of the present utility model is described further:
A kind of device of realizing the seamless pipe controlled rolling and controlled cooling, the shower 2 that is provided with some spray nozzles 3 evenly is provided with the formation cage construction around water ring 1 axis, can guarantee the cooling of seamless steel pipe circumferencial direction evenly, intensity unanimity on the circumferencial direction, cooling water can in time flow away from the gap between the shower 2, effectively avoids cooling water to be detained.
Steel pipe 4 speeds of service and cooling water inflow will be by calculating to guarantee to reach enough cooling capacities in the actual production.The physical dimension of water ring 1 and the seamless steel pipe of certain size are complementary.
