Description
Technical field
The utility model relates to a kind of composite plate blanks casting devices.
Background technique
Conventional alloys cannot meet a variety of in terms of such as delivery vehicle, structure, electronics engineering very well since performance is single
The requirement of performance synthesis, therefore composite material becomes the emphasis of new material research and development.Laminar composite is due at low cost, comprehensive
Can it is good, be widely used, the maximum composite material of output, wherein composite board band is then the most composite wood of current dosage
Material.
The main production process of composite board band is segmented into three classes: one kind is solid phase composite algorithm, including method hot rolling, cold
Rolling compound etc., the second class are liquid-solid composite method, such as reverse solidification method, and third class is liquid composite algorithm, such as continuous casting process.It passes
The production technology of the composite board band of system is Rolling compund, and the more new surfaces of creation are compound to realize under the big pressure rate of high temperature,
But they the shortcomings that are: casting is molten steel to be poured into tundish from steel ladle, and the acquisition of molten steel needs to contain in molten iron and steel scrap
There are the impurity such as C, Mn, Si, P, S, in low temperature melting process, C, Si, P, S are oxidized, and the impurity of elemental is made to become compound state
Impurity, so that the later period further removes impurity.Iron rust (ingredient Fe of the oxygen in furnace charge2O3·2H2O), aoxidize
Iron sheet, the iron ore of addition and oxygen and oxygen blast in air.The oxidation process of various impurity is the interface in clinker and molten steel
Between carry out.Oxidation process is the de- charcoal carried out at high temperature, dephosphorization, degassing, impurity elimination qualitative response, deoxidation, desulfurization and tapping.
Aoxidize latter stage, excessive oxygen contained in steel, by be added into molten steel blocky or powdery ferroalloy or polynary element alloy come
Remove superfluous oxygen in molten steel, the pernicious gas CO of generation is discharged with furnace gas, the clinker of generation can further desulfurization, i.e., last
Tapping process in, slag, steel mix flushing strongly, increase desulphurization reaction.The molten steel for smelting out from converter contains on a small quantity
Gas and impurity, usually molten steel is injected in refining packet, Argon, degassing, the processes such as ladle refining is carried out, obtains purer
Molten steel.
During field of material processing, especially composite casting, avoid molten steel be oxidized be composite casting technique most
Substantially most important target.However in the actual process, molten steel in casting process inevitable ingress of air, resistance to material, cover
The substances such as lid agent, the oxidation that wherein ingress of air generates influence maximum to the quality of final bimetal, while being also to be most difficult to control
System, cause just to have occurred and that oxidation while molten steel is cast in mold, cause when serious molten steel dross can not continue into
Row casting.
