Abstract
The invention discloses a kind of stabilizing roller centre spinning method, comprise the following steps：1）Iron-based material molten metal and cobalt-base alloys molten metal are subjected to melting in two smelting furnaces respectively；2）Removed slag after iron-based material molten metal and cobalt-base alloys molten metal are melting down and deoxidation treatment；3）Outer layer cobalt-base alloys molten metal is first subjected to spun casting, the outer layer cobalt-base alloys molten metal gross weight for being cast to need to cast when outer layer cobalt-base alloys molten metal 35% 40% when add glass dregs protective agent with outer layer cobalt-base alloys molten metal；4）Wait to have cast after outer layer cobalt-base alloys molten metal, the iron-based material molten metal for internal layer of being cast after the solidification of outer layer cobalt-base alloys molten metal, until terminating, inside and outside double layer of metal liquid under the action of the centrifugal force cooled and solidified for centrifugation stabilizing roller blank.The present invention substantially reduces glass dregs addition.
Description
Technical field
The present invention relates to a kind of metal casting method, and in particular to a kind of metal centre spinning method.
Background technology
In order to corrosion-resistant, wear-resisting, cobalt-base alloys roller set is set with roller outer wall, this stabilizing roller typically uses centrifugal casting
Make method：Iron-based material molten metal and cobalt-base alloys molten metal are first subjected to melting in two smelting furnaces respectively, then by outer layer
Cobalt-base alloys molten metal carries out spun casting, after outer layer cobalt-base alloys molten metal of waiting to have cast, in outer layer cobalt-base alloys metal
The iron-based material molten metal of casting internal layer after liquid solidification, until terminating, inside and outside double layer of metal liquid cools down under the action of the centrifugal force
It is solidified as centrifuging the blank of stabilizing roller.To prevent inner surface metal liquid oxidation, centrifuged by outer layer cobalt-base alloys molten metal
Glass dregs protective agent is added during casting.It is a kind of disclosed in China Patent Publication No. CN 101596584A " sinking roller or stabilizing roller
Compound centrifugal manufacturing method ", wherein one of step are：Outer layer cobalt-base alloys molten metal is first subjected to spun casting, treats outer layer cobalt
Based alloy molten metal is cast to be closed during the 20%-30% for the outer layer cobalt-base alloys molten metal gross weight for needing to cast with outer layer cobalt-based
Golden molten metal adds glass dregs protective agent；The defects of this compound centrifugal manufacturing method, is：The addition of glass dregs protective agent is too early,
Waste more.
The content of the invention
The present invention in view of the shortcomings of the prior art, proposes a kind of stabilizing roller centrifugal casting that can substantially reduce glass dregs addition
Make method.
The present invention is achieved through the following technical solutions technical goal.
Stabilizing roller centre spinning method, it is theed improvement is that：Comprise the following steps：
1）Iron-based material molten metal and cobalt-base alloys molten metal are subjected to melting in two smelting furnaces respectively；
2）Removed slag after iron-based material molten metal and cobalt-base alloys molten metal are melting down and deoxidation treatment；
3）Outer layer cobalt-base alloys molten metal is first subjected to spun casting, treats that outer layer cobalt-base alloys molten metal is cast to need to cast
Outer layer cobalt-base alloys molten metal gross weight 35%-40% when with outer layer cobalt-base alloys molten metal add glass dregs protective agent；
4）Wait to have cast after outer layer cobalt-base alloys molten metal, the iron for internal layer of being cast after the solidification of outer layer cobalt-base alloys molten metal
Sill molten metal, until terminating, cooled and solidified is to centrifuge the blank of stabilizing roller to inside and outside double layer of metal liquid under the action of the centrifugal force.
The present invention compared with prior art, has the positive effect that：Treat that outer layer cobalt-base alloys molten metal is cast to need
During the 35%-40% of the outer layer cobalt-base alloys molten metal gross weight to be cast glass flux shielding is added with outer layer cobalt-base alloys molten metal
Agent, so, substantially reduce glass dregs addition.
Embodiment
With reference to embodiment, the invention will be further described.
