More to develop to directions such as large-scale, high automation, noble and unsullied purification and great surface qualities, this is just to Strip hot rolling line
Technique and engineering design propose higher requirement.
Because ingot casting is in the condition of high temperature in heating and course of hot rolling（Generally 600~1100 DEG C）, thus copper and
The non-ferrous metal plate bands such as copper alloy, titanium or titanium alloy, nickel and nickel alloy are both needed to examine when producing it using hot-rolling mill
Consider the removal of surface scale, and then improve the surface quality and dimensional accuracy of hot-rolled product, reduce roll wear, reduce subsequently
Processing, raising yield rate.
Oxide skin during metal hot rolling at present mainly using the modes such as the pressure of water under high pressure, impulsive force and big flow come
It is removed, wherein the pressure of water under high pressure is 8~35MPa according to the unusual of metal types.Metal utilizes setting after coming out of the stove
High-pressure water device between heating furnace and hot-rolling mill is once descaled, using being arranged on hot-rolling mill machine in the operation of rolling
High-pressure water device in frame carries out secondary scale removal.
Due to above reason, in non-ferrous metal strip hot rolling technology and engineering design, the waste water that descales need to be considered（Bag
Include the outer cold water of roller-way, finishing equipment outer cold water, the roller technology lubricant medium water on production line）Collection and purification and oxide skin it is heavy
