Description
Technical field
The utility model belongs to Rolling-mill Auxiliary Facilities field, is specifically related to a kind of milling train rolled piece temperature balancing device.
Background technology
In rod hot rolling process, rolled piece, owing to being subject to the effect of roll draught pressure and frictional force, produces violent distortion heat and frictional heat, and rolled piece temperature raises, and rolled piece tissue is difficult to accurate control, thereby cannot meet the rolling needs of particular characteristic steel; Because can making rolled piece, the rising of rolled piece temperature in guide and guard, there is to swing spring simultaneously, and also abnormal serious to the wearing and tearing of guide and guard.At present the rolled piece in rolling bar process is cooling, is mainly that online water cooling plant is set after milling train unit, and when the method cannot be to rolling, the temperature of rolled piece carries out accurately effectively controlling, and then can not obtain the product that meets particular organization and performance.
Utility model content
For the deficiencies in the prior art and defect, the utility model provides a kind of milling train rolled piece temperature balancing device, and this device can be controlled the temperature of rolled piece effectively in the operation of rolling.
To achieve these goals, milling train described in the utility model comprises guide and guard head, refrigerating head shell, refrigerating head core pipe, water inlet pipe and cooling tube with rolled piece temperature balancing device, water inlet pipe is provided with the valve for controlling the flow of water in water inlet pipe, one end of cooling tube is connected with guide and guard head, one end of refrigerating head shell is socketed on the other end of cooling tube, refrigerating head core pipe box is connected in the other end of refrigerating head shell, the side of refrigerating head shell is provided with water inlet, and the delivery port of water inlet pipe is connected with the water inlet of refrigerating head shell side.
One end of described refrigerating head core pipe and the end fixed seal connection of refrigerating head shell, the gap that has annular between the side of the refrigerating head core pipe other end and the inwall of refrigerating head shell, the water inlet of refrigerating head shell side is connected with cooling tube by the gap of described annular.
Described cooling tube is fixedly connected with refrigerating head shell by the first bolt.
Described refrigerating head core pipe is by the second bolt and the fixed seal connection of refrigerating head shell.
Compared with prior art, the beneficial effects of the utility model are:
Milling train described in the utility model uses rolled piece temperature balancing device in the process of work, rolled piece enters into cooling tube by guide and guard head, water in water inlet pipe enters into cooling tube through the water inlet of refrigerating head shell side, realize the cooling to rolled piece, effectively suppress rolled piece temperature rise, the temperature of rolled piece while simultaneously carrying out controlled rolling by the flow of water in valve control water inlet pipe, thereby the temperature of rolled piece can be controlled in the scope of the required deformation temperature of product, and then obtain best tissue and optimum properties of product; Reduce the wearing and tearing of rolled piece simultaneously by guide and guard head, reduce roll alternating thermal stress, reduce roller consumption.
Further, the water inlet of refrigerating head shell side is connected with cooling tube by the gap of annular, when rolling, the reverse spray that the high temperature rolled piece shutting out from roll pass is subject to 360 ° of ring-type high-pressure cooling waters in cooling tube carries out cooling, thereby effectively improves the cooling efficiency of rolled piece.
Brief description of the drawings
Fig. 1 is generalized section of the present utility model.
Wherein, 1 is that guide and guard head, 2 is that cooling tube, 3 is that refrigerating head shell, 4 is that refrigerating head core pipe, 5 is that water inlet pipe, 61 is that the first bolt, 62 is the second bolt.
Detailed description of the invention
Below in conjunction with embodiment and accompanying drawing, the utility model is specifically described:
With reference to figure 1, milling train of the present invention comprises guide and guard 1, refrigerating head shell 3, refrigerating head core pipe 4, water inlet pipe 5 and cooling tube 2 with rolled piece temperature balancing device, water inlet pipe 5 is provided with the valve of the flow for controlling water inlet pipe 5 interior water, one end of cooling tube 2 and guide and guard 1 are connected, one end of refrigerating head shell 3 is socketed on the other end of cooling tube 2, refrigerating head core pipe 4 is socketed in the other end of refrigerating head shell 3, the side of refrigerating head shell 3 is provided with water inlet, and the delivery port of water inlet pipe 5 is connected with the water inlet of refrigerating head shell 3 sides.
It should be noted that, one end of refrigerating head core pipe 4 and the end fixed seal connection of refrigerating head shell 3, between the side of refrigerating head core pipe 4 other ends and the inwall of refrigerating head shell 3, there is the gap of annular, the water inlet of refrigerating head shell 3 sides is connected with cooling tube 2 by the gap of described annular, and cooling tube 2 is fixedly connected with refrigerating head shell 3 by the first bolt 61; Refrigerating head core pipe 4 is by the second bolt 62 and 3 fixed seal connections of refrigerating head shell, and the hydraulic pressure of the water in water inlet pipe 5 is less than or equal to 2.5MPa.
Specific works process of the present utility model is:
In the time that high-pressure cooling water enters the inner chamber of refrigerating head shell 3 by water inlet pipe 5 and valve, the obstruction that is subject to refrigerating head core pipe 4 forms after 360 ° of circular flows and evenly sprays from the gap location of the two, when rolling, the reverse spray that the high temperature rolled piece shutting out from roll pass is subject to 360 ° of ring-type high-pressure cooling waters in cooling tube 2 carries out cooling, control rolled piece temperature thereby reach, the object that obtains best tissue and optimum properties of product finally passes and enters next process from refrigerating head core pipe 4.
Technical scheme in above-described embodiment is known intactly description, and obviously, described embodiment is only the utility model part embodiment, instead of all; Based on the embodiment in the utility model, those of ordinary skill in the art are not making the every other embodiment obtaining under creative work prerequisite, all belong to the scope of the utility model protection.
