1, owing to adopt the branch body structure, loaded down with trivial details complexity is installed;
2, because working roll is the CVC+ roll forming, and this cuts the water device and working roll binding face slit is big, so cut the water poor effect, the steel plate that cooling water easily infiltrates in rolling directly influences product quality.
3. milling train is in the operation of rolling, and this cuts the water device and the working roll roll surface has certain pressure, and after this was cut the water device and may wear to a certain degree, the set bolt of aluminum strip contacted with roll surface, thereby can bring damage to roll surface, form have a rule draw trace A (see figure 4).
Summary of the invention
Technical problem to be solved by this invention provide a kind of easy for installation, cut the water device and working roll applying slit is little, it is better to cut the water effect, can not damage the installation for cutting through water of worker rollers of heavy plate mill of working roll roll surface, to overcome the deficiency that prior art exists.
In order to solve the problems of the technologies described above, the present invention adopts following technical scheme:
This installation for cutting through water of worker rollers of heavy plate mill is formed in one cuts the water bar, cut the water bar and be toxoplasm, toxoplasm has two water swords of cutting, and be formed with protruding block in the middle of the back at toxoplasmatic middle part, described two each of cutting in the water sword is cut the water sword and is included a blade, cuts the water sword and is connected by described middle part for described pair.
Described material of cutting the water bar is selected nonmetallic materials for use.
The root of described protruding block has mounting groove.
Described mounting groove is for to eject the adaptive step slot of air cavity groove with foreplate.
Described two water sword of cutting carries out the transition to described middle part symmetrically from two blades are ascending.Adopt technique scheme, owing to be integrative-structure, this cut the water device be installed on foreplate and eject in the groove of air cavity, very convenient.Block rubber with respect to the prior art midplane, cutting arc two of water bar cuts water sword structure and has certain stress balance effect, twoly cut the reaction force that the water sword bears and to offset the part tangential forces, improved the stability of device, and be not subjected to the influence of working roll rotating.During work, that cuts the water bar two cut the water sword and is adjacent to working roll, utilizes working roll to two reaction forces of cutting the water sword, makes two blades be adjacent to working roll all the time, obtains the desirable water effect of cutting.Because containing metal not in this device is not even wearing and tearing can bring damage to working roll yet.
Therefore, installation for cutting through water of worker rollers of heavy plate mill of the present invention, have easy for installation, to cut water good, can not damage the working roll roll surface, the advantage of working stability.
