The utility model has simple structure, is based on the structure of the traditional sprinkler, and realizes the purpose of reducing the temperature of the sprinkler by circularly introducing cold water in the cold water pipe; the utility model can cool down the water sprayer in a balanced way by adding the cold water pipe at the position of the water sprayer near the high temperature, thereby achieving the purpose of protecting the water spraying pipe.

Description

Anti-deformation water sprayer

Technical Field

The utility model belongs to the field of roller manufacturing, and particularly relates to an anti-deformation water sprayer for cooling a roller in the roller quenching process.

Background

The main production process flow of the roller comprises centrifugal casting, quenching, cooling and the like. In the quenching process, because the roll body and the roll neck of the roll are not integrally cast, the roll body and the roll neck are required to be quenched respectively, if a water quenching method is adopted, the simultaneous influence on the roll neck or the roll body cannot be avoided, and the conditions of different quenching degrees of crystals of the roll neck and the roll body, crack generation and even fracture can be caused.

In view of the above situation, currently, roller manufacturers generally adopt air cooling or air cooling to quench the roller body and the roller neck respectively. The air cooling technology for the roll neck mainly adopts a circular ring with the diameter larger than that of the roll neck to cover the water sprayer on the periphery of the roll neck, meanwhile, cooling water is introduced into the circular ring to cool the roll neck, and an induction coil is generally arranged between the water sprayer and the roll neck to control the displacement distance of the water sprayer (as shown in figure 4). Because the water sprayer needs to work in a high-temperature environment for a long time, the water sprayer is easy to deform in the later stage of quenching, and irreversible deformation can occur for a long time, so that the water sprayer cannot be used normally, namely cannot be sleeved on the periphery of the roll neck of the roll.
