" recovery " is to the alloy that comprises in the molten steel after injecting and a kind of tolerance of additive capacity.Recovery is expressed as that injection back comprises in steel is injected at the alloy in the steel or the percentage ratio of additive.The percentage ratio that comprises in this steel after the injection is big more, and reclaiming also will be big more.Reclaim big more concerning steel manufacturers the expression cost low more because injection to contain the core metal silk few more.And the predictability and the repeatability that reclaim the chemical property of big more ordinary representation final steel can be high more.
As everyone knows, with containing in the core metal silk of additive alloy (being ground to diameter usually less than 1 millimeter powder) the ladle shell of packing into, the result who this wire degree of depth is injected the molten bath reclaims to significantly improve.But this area is also known is the disadvantageous effect that the recovery of special additive alloy is subjected to oxygen level in molten bath and top, the molten bath slag.Might reduce the oxygen level of molten bath and slag; But till the ass ascends the ladder oxygen level is reduced to zero.The most common is, has a certain amount of oxygen all the time and stays in molten metal and the slag, additive alloy is reclaimed have a negative impact.Oxygen level is high more, and this disadvantageous effect is big more.
The contriver believes, additive alloy powders particle 16 can become be dissolved in molten metal 10 before, the oxygen 13 in the molten metal 10 makes the surface oxidation of additive alloy 16.This situation as shown in Figure 1.In this case, zone of oxidation 19 covers additive alloy powders particle 16, therefore reduces the overall consistency of particle 16, makes particulate buoyancy greater than steel 10.For example, the density of Nb is 8.57gm/m
3, Nb
2O
5Density be 4.47gm/m
3, and the density of steel is 7.6gm/m
3Fig. 2 shows that more low-density oxide alloy rises towards the surface of molten steel 10.In other cases, oxide skin 19 becomes the blocking layer of additive for fusing alloy core 16.For example, the temperature of fusion of 70%FeTi is 1085 ℃, and TiO
2Temperature of fusion be 1850 ℃, still, the temperature of molten steel 10 is about 1600 ℃ usually.In Fig. 3, shown this problem.The effect of these mechanism is to rise to the slag surface at additive alloy particle 16 not make it be dissolved in melt metal 10 fully before being absorbed.
In other currently known methodss, the purpose that additive alloy 16 is injected molten bath 10 is to be formed with nitride and/or the carbide that benefits the finished product.For many years, in order to increase the nitrogen content in its molten bath 10, the steel manufacturer uses calcium cyanamide (CaCN
2).Referring to, for example United States Patent (USP) the 3rd, 322, No. 530.In addition, find when adopting that No. 114 described contains the core metal silk and be injected in the molten bath 10 and add CaCN according to United States Patent (USP) the 4th, 897
2The time, significantly improved the nitrogen recovery.
Although the improvement in these prior art fields is arranged, still need to improve at molten metal the particularly recovery in the molten steel.
