Abstract

The utility model discloses a roller cooling water assembly, which comprises a water supplying assembly, a water distributing pipe and narrow and long water jets which are uniformly distributed alongthe water distributing pipe, the water distributing pipe is transversely arranged along rollers, and the water jets are arranged along the axial cords of the rollers and are just opposite to rolling grooves of the rollers. The assembly adopts the structure that the diameter of the water jets is larger than or equal to the width of the rolling grooves of the roller, can guarantee all the rolling grooves of the rollers to be cooled, enables the rollers to be uniformly cooled, avoids the phenomena of crack and heavy abrasion of the rollers and the chip falling of the surfaces of the rollers and the like caused by the cooling problem, enables the cooling effect of rolled pieces to be good, reduces the failure rate of the rolling mill, prolongs the manufacturing period, improves the normal measuring efficiency of the rolling mill, and reduces the manufacturing cost.

Description

Roll cooling water assembly

Technical field

The utility model relates to a kind of rolling mill parts, particularly a kind of roll cooling water assembly.

Background technology

Rolling mill roll cooling is a link important in the steel rolling process, if inhomogeneous, the bad body of roll place temperature of local cooling condition raises, and causes that roll chaps, serious wear and roller surface fall phenomenons such as piece.In the prior art, rolling mill roll cooling generally adopts the mode of spraying cooling water to cool off, and cooling effect not only influences the hot convexity and the rolling quality of roll, and cooling water also directly acts on the rolled piece, and the cooling velocity of rolled piece is had considerable influence.The best duty of roll cooling is that cooling water forms the thick and heavy moisture film of one deck attached to body surface, makes its cooling evenly, fully; Avoid occurring iron scale to greatest extent in the situation of body of roll adhesion and the generation of fatigue point.

In the prior art, roll cooling water assembly generally adopts upper hose and water distributor, water jet is set on the water distributor, the effect of water distributor be can be to greatest extent with water distribution around whole roll, and water jet directly sprays cooling with water, and that water jet is provided with is unreasonable, cause the groove both sides of roll to can not get cooling, do not reach even cooling purpose, thereby the cooling of the duty of breaker roll and rolled piece has adverse effect, make roller surface that problems such as be full of cracks take place, influence ordinary production.

Therefore, need breaker roll cooling water assembly to transform, can guarantee that whole grooves of roll fully cool off, and make the roll cooling evenly, avoid because the cooling problem causes that roll chaps, serious wear and roller surface fall phenomenons such as piece, and make the rolled piece cooling effect good.

The utility model content

In view of this, the utility model provides a kind of roll cooling water assembly, can guarantee that whole grooves of roll fully cool off, and makes the roll cooling evenly, avoid because the cooling problem causes that roll chaps, serious wear and roller surface fall phenomenons such as piece, and make the rolled piece cooling effect good.

Roll cooling water assembly of the present utility model, comprise supply mains, water distributor and along the uniform thin-and-long water jet of water distributor, described water distributor is along the roll horizontally set, water jet is along the roll axis setting and over against roll groove, and described water jet is along the size of the roll axis width of groove more than or equal to roll.

Further, the opening size of described water jet is greater than 8mm;

Further, described water distributor is a semicircular structure, is arranged on the excircle of roll, and breaker roll forms the semi-surrounding structure;

Further, described water jet is arranged on the short tube of closed at both ends, and described short tube is parallel to roll axis and is communicated with water distributor.

The beneficial effects of the utility model: roll cooling water assembly of the present utility model, adopt the structure of water jet more than or equal to the width of groove of roll, whole grooves that can guarantee roll fully cool off, and make roll cooling evenly, avoid because the cooling problem causes that roll chaps, serious wear and roller surface fall phenomenons such as piece, and make the rolled piece cooling effect good, thereby reduce the fault rate of milling train, prolong the ordinary production cycle, improve the ordinary production efficient of rolling mill, reduce production costs.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further described.

Fig. 1 is a structural representation of the present utility model;

Fig. 2 be Fig. 1 along A to view.

The specific embodiment

Fig. 1 is a structural representation of the present utility model, Fig. 2 be Fig. 1 along A to view, as shown in the figure: the roll cooling water assembly of present embodiment, comprise supply mains 1, water distributor 2 and along the uniform thin-and-long water jet 3 of water distributor 2, described water distributor is along roll 6 horizontally sets, water jet 3 is along roll 6 axis settings and over against roll groove 61, described water jet 3 is along the size of roll 6 axis groove 61 width more than or equal to roll 6, in the present embodiment, water jet 3 is along the size of roll axis groove 61 width greater than roll 6, guarantee that roll fully cools off, avoid because the rolling mill fault that the cooling problem occurs;

In the present embodiment, the opening size of water jet 3 can adopt 9mm greater than 8mm, prevents that foreign material such as incrustation scale from stopping up water jet and influencing the regular supply of cooling water;

In the present embodiment, water distributor 2 is a semicircular structure, is arranged on the excircle of roll 6, and breaker roll 6 forms the semi-surrounding structure, be beneficial to comprehensive breaker roll 6 coolings of cooling water, and cooling evenly;

In the present embodiment, water jet is arranged on the short tube 4 of closed at both ends, and described short tube 4 is parallel to roll 6 axis and is communicated with water distributor by pipe nipple 5, and is simple in structure, making is easy and save cost.

Explanation is at last, above embodiment is only unrestricted in order to the explanation the technical solution of the utility model, although the utility model is had been described in detail with reference to preferred embodiment, those of ordinary skill in the art is to be understood that, can make amendment or be equal to replacement the technical solution of the utility model, and not breaking away from the aim and the scope of technical solutions of the utility model, it all should be encompassed in the middle of the claim scope of the present utility model.
