Abstract
The invention provides a centrifugal casting compound bi-metal rolling technology, making high alloy anti-grinding cast iron at the surface, inner layer being complex rolling sleeve with low carbon steel, for mechanical processing, then for heat treatment, with the core shaft filled with complex rolling sleeve, with core shaft and roll sleeve low carbon steel for welding, and rolling it to required dimension. It is simple in process, convenient in production with high durability.
Description
Affiliated technical field
The present invention relates to a kind of manufacturing technique method of centrifugal casting composite bimetallic combined type rolling-mill roller, especially adopt centrifugal method to cast out the bimetal composite roller shell, the combined type rolling-mill roller of welding axle.
Background technology:
At present, domestic small-sized, middle low speed rod-rolling mill adopts chilled cast iron roll more, the groove quick abrasion, and roll campaign is low, needs often to repair groove and change roll, influences the activity duration, not only lacks steel rolling, and influences the stocking precision.In recent years, some factory begins to adopt low nickel chromium triangle molybdenum cast iron roll and middle nickel chromium triangle molybdenum cast iron roll on finishing mill, but can not deal with problems fully, pass of the small-sized planishing roll of low, middle nickel chromium triangle molybdenum can only roll about 200t, middle pass of low speed wire roll can only roll tens tons, class of factory that output is high need change groove (pass) several times, and service life is very undesirable, and serious restriction is produced.The problem that small-sized planishing roll exists the roll breakage phenomenon also often occurs during rolling angle iron except that milling round steel, screw-thread steel wear no resistance.Domestic in recent years introduced not have at a high speed turn round rod-rolling mill, middle-size and small-size alloy bar material and continuous section rolling machine and make common roll more can't adapt to the requirement of production.Domestic at this situation, developed low carbon high chrome casting iron composite casting roll.Low carbon high chrome casting iron composite casting roll has high rigidity, high-wearing feature, and its mandrel has high strength, high tenacity, and at present, the rich chromium cast iron composite roll is extensively used.But its production process complexity, technical difficulty and manufacturing cost are all very high.
Summary of the invention:
In order to overcome the deficiency that existing roll exists, the invention provides the capable machining of a kind of centrifugal casting composite bimetallic, carry out quenching heat treatment then, the hole of reprocessing roller shell after the heat treatment, with the axle roller shell of packing into, and axle and roller shell low-alloy steel partly welded, with the Roller Machining that assembles to the size that requires.
The invention has the beneficial effects as follows that production process is simple, easy to operate, the yield rate height is difficult for generation by its heat treatment process and splits the roller phenomenon, also possesses the characteristics of high life simultaneously.
Specific embodiments:
Description of drawings
Below in conjunction with drawings and Examples the utility model is done detailed explanation.
Accompanying drawing is a generalized section of the present invention.(1) axle, (2) high alloy antifriction cast iron layer, (3) low-alloy steel layer, (4) weld bond among the figure.
The specific embodiment:
At first adopt the centrifugal casting composite manufacturing method, cast out the roll surface surface and be high alloy antifriction cast iron layer (2), inner surface is the compound roller shell of low-alloy steel layer (3), machining is carried out to it in the annealing back, carry out quenching heat treatment again, with the axle (1) that the processes roller shell of packing into, and axle (1) and compound roller shell low-alloy steel layer (3) part welded.Axle (1) is a low-alloy steel, and composition is C:0.28～0.35%, Si:1.0～1.5%, Mn:0.8～1.2%.Weld bond (4) should guarantee to have the dimensions, with the Roller Machining that assembles to the size that requires.
