Installation for cutting through water of worker rollers of heavy plate mill

Abstract

The invention discloses a thick board rolling mill machine working roller water cutting device that is an integrative water cutting stick, which is a segment that includes double water cutting blade and convex block. The invention has the advantages of convenient to install, good water cutting effect and working stability.

Description

technical field [0001] The invention relates to a thick plate rolling mill, in particular to a water cutting device for work rolls of a wide and large thick plate rolling mill. Background technique [0002] A thick plate rolling mill as shown in Figure 1 in the prior art is a modern ultra-wide thick plate rolling mill, and its work roll 5 is CVC + Roll shape, in the process of rolling a thick plate, the work roll 5 is in contact with the hot slab 6 during rolling, and the temperature of the roll surface 51 increases so that the hardness decreases, which brings a negative impact on the service life of the work roll 5 and the quality of the rolled product. to influence. In order to ensure that the temperature of the work roll 5 is not too high, it is necessary to carry out cooling water cooling treatment on the roll surface 51 of the work roll 5 . However, the hot slab 6 in rolling has high requirements on temperature. If the cooling water on the work roll 5 flows to the hot...

AI Technical Summary

Problems solved by technology

[0003] 1. Due to the split structure, the installation is cumbersome and complicated;

[0004] 2. Since the work roll is CVC+ roll shape, the gap between the water cutting device and the work roll bonding surface is large, so the water cutting effect is not good, and the cooling water is easy to penetrate into the rolling steel plate and directly affect the product quality
