Claims (1)

Способ производства композитных прокатных валков, при котором в кольцевом зазоре между формирующей поверхностью кристаллизатора и наплавляемой поверхностью заготовки создают рабочий слой путем заплавления кольцевого зазора чугунным расходуемым электродом, отличающийся тем, что в качестве кристаллизатора используют металлическую оболочку, которую после заплавления кольцевого зазора удаляют механической обработкой, при этом толщину стенки оболочки определяют из соотношения
δ = t•k1•k2,
где δ - толщина стенки оболочки, мм;
t - толщина наплавленного рабочего слоя, мм;
k1 - коэффициент, учитывающий зависимость толщины стенки оболочки от толщины наплавленного слоя;
k2 - коэффициент, учитывающий зависимость толщины стенки оболочки от диаметра наплавляемой заготовки.A method of manufacturing composite rolling rolls, in which a working layer is created in the annular gap between the mold surface of the mold and the deposited surface of the workpiece by melting the annular gap with a cast iron consumable electrode, characterized in that a metal shell is used as the mold, which is removed by machining after melting the annular gap, wherein the wall thickness of the shell is determined from the ratio
δ = t • k 1 • k 2 ,
where δ is the shell wall thickness, mm;
t is the thickness of the deposited working layer, mm;
k 1 - coefficient taking into account the dependence of the shell wall thickness on the thickness of the deposited layer;
k 2 - coefficient taking into account the dependence of the shell wall thickness on the diameter of the deposited workpiece.
