Abstract

The utility model relates to a wire rod cooling roll type conveyor guide roll which comprises a guide roll body, cooling fins are arranged at the two ends of the guide roll body, and the guide roll body is of a hollow cast steel structure. The self-weight of the guide rail is about 100kg and is lowered by 44% than the design weight of an original guide roll, therefore, maintenance is more convenient, and labor intensity of a maintenance man is reduced. Due to the reduction of the self weight of the guide roll, about 400 guide rolls of a whole conveyor are light in linkage, loads of transmission chain wheels and chains are reduced substantially, service life of guide roll chains and the chain wheels is prolonged by at least one period, maintenance cost is reduced substantially, and labor productivity is improved substantially.

Description

The cooling roller path deflector roll of a kind of wire-rod roll

Technical field

The utility model belongs to technical field, particularly relates to the cooling roller path deflector roll of a kind of wire-rod roll.

Background technology

Along with the development of high-speed rod-rolling mill, be at present inherence and the surface quality that improves the high-speed rod product, realize that controlling cooling after the wire rod hot rolling is once requisite cooling method.So-called to control cooling be to utilize after hot rolling the waste heat of wire rod to control its rate of cooling with certain control device, thereby obtain the inherent organization mechanics performance of our needed wire rod, and scale on surface quantity etc.Domestic newly-built high-speed rod-rolling mill almost all adopts the cooling roller path of the loose volume of stelmor at present.The cooling section of this roller path is that multistage is controlled, blower fan carries out cooling conveyer roller-way, general roller-way length is 100 meters left and right, deflector roll quantity is 400, blower fan is configured to 16 left and right, linked transmission is all adopted in transmission between deflector roll, a sprocket wheel is installed on each deflector roll and is connected with chain, by the motor and speed reducer drive part by part.

Roller path rotates the drive wire rod by deflector roll and advances, due to the fixed contact point that does not exist between wire rod and deflector roll, again because roller-way can be divided into some sections, transmission separately, so can make contact point change between wire rod circle and circle by changing each section roller table speed, make the cooling more even of each contact point of wire rod and overlapped points place, therefore the roller of the roller path of existing design is made with solid cast, two ends are processed with the radiating gill (see figure 1), but through facts have proved that there are many design defect in this deflector roll:

The one, owing to being subjected to wire rod rolling mill practice needs, conveyer roller-way blower fan is only opened 1-2 point when the rolling low carbon common wire, and most of deflector roll will bear the high temperature of 500-900 ℃, makes that deflector roll is very easy to deform, bending, thereby affect the normal conveying of wire rod, affect the moulding of wire rod.

The 2nd, due to technological requirement, every conveyor rail has the rapid several functions such as play that all standing and roller-way are creeped, so cause driving chain and sprocket wheel operating cycles on deflector roll shorter, operating cycles the longest as chain is 6 months, if untimely replacing will cause chain breakage, cause and stop rolling, that wire rod occurs is air-cooled, waste product, milling train are cut the phenomenons such as useless, has a strong impact on lumber recovery.

Summary of the invention

The utility model pressing plate provides a kind of simple in structure for solving the technical matters that exists in known technology; weight gentlier, not yielding; and can effectively reduce the nonscheduled down time that causes because of deflector roll distortion, driving chain fracture; reduce the maintenance cost of conveyer, increasing work efficiency guarantees the cooling roller path deflector roll of a kind of wire-rod roll of production continuous rolling.

The technical scheme that the utility model pressing plate is taked for the technical matters that exists in the solution known technology is:

The cooling roller path deflector roll of a kind of wire-rod roll comprises the deflector roll body, and the two ends of described deflector roll body are provided with radiating gill, and described deflector roll body is hollow cast steel structure.

The hollow position of described deflector roll body is evenly equipped with some ventilating heat dissipating holes.

Advantage and good effect that the utility model pressing plate has are: of the present utility model from focusing on the 100kg left and right, reduced by 44% than former deflector roll design weight, keep in repair convenient, reduced the labour intensity of maintenance man, due to the minimizing of deflector roll deadweight, nearly 400 deflector rolls interlock of whole piece conveyer is very slim and graceful, the load of driving chain wheel, chain significantly reduces, the use of deflector roll chain, sprocket wheel extends one-period at least, and service expenditure significantly reduces, and has significantly improved labor efficiency.

Description of drawings

Fig. 1 is the former project organization schematic diagram of the cooling roller path deflector roll of wire-rod roll;

Fig. 2 is the utility model structural representation.

In Fig. 1 and Fig. 2,1. radiating gill, 2. deflector roll body, 3. ventilating heat dissipating hole.

The specific embodiment

For can further understand content of the present utility model, Characteristic, and exemplify following examples, and coordinate accompanying drawing to be described in detail as follows:

As shown in Figure 2, the cooling roller path deflector roll of a kind of wire-rod roll, comprise deflector roll body 2, the two ends of deflector roll body 2 are provided with radiating gill 1, deflector roll body 2 is hollow cast steel structure, in order to prevent deflector roll distortion, be evenly equipped with some ventilating heat dissipating holes 3 at the hollow position of deflector roll body, make the cooling more quick of deflector roll.

Of the present utility model from focusing on the 100kg left and right, reduced by 44% than former deflector roll design weight, keep in repair convenient, reduced the labour intensity of maintenance man, due to the minimizing of deflector roll deadweight, nearly 400 deflector rolls interlock of whole piece conveyer is very slim and graceful, the load of driving chain wheel, chain significantly reduces, the use of deflector roll chain, sprocket wheel extends one-period at least, and service expenditure significantly reduces, and has significantly improved labor efficiency.

The above is only preferred embodiment of the present utility model, be not that the utility model is done any pro forma restriction, any simple modification, equivalent variations and the modification on every foundation technical spirit of the present utility model, above embodiment done all still belong to the technical solution of the utility model scope.
