Quality；It is inverse after machine before machine to spray water for the splash for stopping water under high pressure, it is ensured that personnel and equipment safety；Pre- bath is low pressure water, is used
In descaling header before water under high pressure is rushed, water state is maintained, eliminate the water hammer that water under high pressure opens moment and produces impact, protection
System original paper.
Inverse water pipe is designed as before the machine of original system, after machine：In the master of roughing inlet high pressure water de-scaling valve group outlet
Branch line is drawn on pipeline, for inverse water spray after machine before machine.Inverse water spray passes through collector nozzle and high pressure descaling water contrainjection,
Play the effect for stopping that high pressure descaling water is excessive.
Two shortcomings of original system：1st, because inverse water spray collector and entrance descaling header share an injection valve group, compared with machine
De-scaling valve group increased 1/3 pre- bath demand afterwards, and the flow of its pre- bath is identical with de-scaling valve group after machine, does not increase
Amount of water, thereby results in pre- amount of flush water not enough, it is impossible to eliminate water hammer, causes entrance descaling system to be impacted huge, and equipment is frequently
Numerous damage, maintenance cost is increased while having a strong impact on rolling line operating rate.2nd, it is inverse in the case where water under high pressure total flow is constant
Water spray serves shunting action, reduces the pressure of water under high pressure, so as to reduce hitting power, scale removal effect is influenceed, to product
There are potential risks in surface quality.

Vertical spraying system and pre- flushing system, eliminate water hammer, can reduce or even can to prevent roughing mill high-pressure water descaling inverse
The accident that water pipe and water under high pressure pipeline snap, inverse spray manifold nozzle falls, improves operating rate, reduces the buying expenses of spare part,
Meet onsite application requirement.
The purpose of this utility model is achieved through the following technical solutions：
It is a kind of realize before roughing mill machine with machine after independent inverse spray water under high pressure device unit, be arranged on roughing entrance de-scaling dress
Put front end, including high voltage charge road, low pressure pipeline, inverse water pipe and injection valve group and valve group of washing by water in advance, the high voltage charge
Preliminary filling water lines and low pressure water lines are connected on road and the low pressure pipeline, have been sequentially communicated in the preliminary filling water lines
First pipe clamp, stop valve, check-valves and pneumatic Scale removing valve, have been sequentially communicated the second pipe clamp, ball valve, have filled in the low pressure water lines
Water valve and check valve, the pneumatic Scale removing valve are connected with the check valve, and the output end of the pneumatic Scale removing valve passes through pipeline
It is connected with the inverse water pipe, blind plate is had additional on the inverse water pipe.
First pipe clamp is provided with least two.
The pipe diameter of the preliminary filling water lines is 120-160mm.The pipe diameter of the low pressure water lines is 50-
70mm。
Compared with prior art, the beneficial effect that the technical solution of the utility model is brought is：
1. the utility model can realize roughing mill against the autonomous working of water injection system, can prevent roughing mill high-pressure water descaling
The accident that inverse water pipe and water under high pressure pipeline snap, inverse spray manifold nozzle falls, it is safe and reliable.
2. the utility model can improve operating efficiency, reduce the buying expenses of spare part, cost-effective.
3. the utility model can improve the hitting power of roughing inlet high pressure water de-scaling, improve scale removal effect, it is ensured that product
Surface quality.
