Definitions
- the present invention relates to a method for producing an iron-based amorphous material at low cost.
- Gold has excellent characteristics as an electromagnetic material, and when used as an iron core material for power transformers, it is said that the iron loss is about 1/3 compared to conventional directional silicon steel sheets. The mass production is delayed.
- the biggest cause is that the price is much higher than that of silicon steel plates, and the main raw materials such as Fe-B account for most of the manufacturing costs.
- the aluminum thermite method is refined by the electric furnace method.
- the electric furnace method consumes a large amount of power, the power price is high and amorphous. Material production costs will also increase.
- the aluminum thermite method is inexpensive to manufacture, but since A 1 and Ti are mixed in F e — B, if this is used as a raw material for the amorphous material, the Ti concentration of the manufactured amorphous material and A 1 concentration increases. It is known that increasing the Ti and A 1 concentrations decreases the magnetic properties, and could not be used as a raw material for amorphous materials unless 1-8 can be removed at low cost.
- the present invention solves the above-mentioned problems of the prior art and efficiently removes A 1 and T i, which lower the magnetic properties, even when inexpensive Fe-B or scrap is used as a raw material for amorphous materials. So cheap Another object is to provide a method for producing an amorphous material.
- the gist of the present invention is as follows.
- Fig. 1 is a graph showing the change over time in the concentration of Ti in molten iron when an iron oxide source is added to the molten iron of the amorphous base metal.
- Fig. 2 is a graph showing the change over time in the concentration of A 1 in molten iron when an iron oxide source is added to the molten iron of the amorphous base material.
- the present inventors have found from experiments using a small melting furnace that Ti and A 1 can be efficiently oxidized and removed by adding iron oxide when the iron-based amorphous matrix is melted. did. Since T i and A 1 are preferentially oxidized compared to B and S i, which are the main components of the amorphous base material, they are oxidized and removed without significantly reducing the yield of B and S i.
- the main raw material blended so as to be the required B and Si components is melted in a melting furnace, and when the molten iron is generated, the iron oxide source containing 55 mass% or more of iron content To oxidize and remove T i and A 1.
- molten iron of an amorphous base material containing B: 3.2 mass% and Si: 1.8 mass% was generated in a melting furnace, heated to 150 ° C., and then molten iron 1
- Figure 1 shows the changes over time in the concentrations of T i and A 1 in molten iron when various iron oxide sources with a mass of 50 kg per ton are added. It can be seen that, for any iron oxide source having an iron concentration of 55% or more, T i and A 1 are reduced to less than 0.05 mass%, which does not affect the magnetic properties. However, the lower the concentration of iron and the higher the amount of gangue other than iron oxide, the lower the rate of oxidation removal of T i and A 1.
- an iron oxide source containing 55% by mass or more of iron with a main raw material blended so as to become the necessary B and Si components is charged in a melting furnace in advance and melted.
- molten iron is produced as a base material.
- dust is generated during the addition, and this form is desirable when the dust collection capacity of the melting furnace is insufficient.
- T i and A 1 are oxidized and removed during the melting stage, the refinement is completed within the time required to melt the raw materials and raise the temperature to the temperature required for the steel.
- the T i concentration was 0.05% by mass or more.
- component composition and its range in the present invention will be described. Unless otherwise specified, the range of component composition is mass%.
- B is an element effective for improving the amorphous forming ability and thermal stability, and an appropriate amount is added according to the requirements of each characteristic. If B is less than 2%, an amorphous phase cannot be stably obtained. On the other hand, if B exceeds 4%, formation of the amorphous phase becomes difficult due to an increase in melting point.
- S i is an element that is effective in improving amorphous formation ability and thermal stability. Yes, the appropriate amount is added according to the requirements of each characteristic. If 3 1 is less than 1%, an amorphous phase cannot be formed stably, while if it exceeds 6%, the effect of improving thermal stability is saturated.
- C is an element effective in improving the magnetic flux density of the ribbon and improving the amorphous form performance (improving the forgeability), and the appropriate content is determined according to the requirements of each property.
- C in an amount of 0.001% or more, preferably 0,003% or more, the wettability between the molten metal and the cooling substrate is improved, and a good ribbon can be formed.
- C when C is 0.01% or more, an effect of improving the amorphous form performance can be obtained. On the other hand, if it exceeds 3%, the effect of improving the magnetic flux density decreases.
- P is an element effective in improving iron loss and amorphous form performance, and an appropriate amount is contained according to the requirements of each characteristic.
- the inclusion of P improves the iron loss and amorphous form performance, and the allowable amount of impurity elements is increased, but if P is less than 0.08%, the amorphous form performance improvement effect and the iron loss improvement effect In other words, the effect of expanding the allowable amount of impurity elements Mn and S does not appear.
- P is an element effective in improving iron loss and amorphous form performance, and an appropriate amount is contained according to the requirements of each characteristic.
- the inclusion of P improves the iron loss and amorphous form performance, and the allowable amount of impurity elements is increased, but if P is less than 0.08%, the amorphous form performance improvement effect and the iron loss improvement effect In other words, the effect of expanding the allowable amount of impurity elements Mn and S does not appear.
- the increase in P content cracks tend to propagate to the ribbon and workability deteriorates.
- the composition of the present invention includes a part of Fe that is 20% or less of the Fe amount, Co, Ni, or 6% or less. Even when it was substituted with one or more of Cr, the effect of the present invention was not particularly impaired.
- Co and Ni have the effect of improving the magnetic flux density, they are expensive, so considering the raw material cost, the replacement is limited to 10% or less, and even 5% or less of the Fe amount. Is preferred.
- Fe, B, S i, C, P, N i, C o, C r as well as known N, T i, Z r, V, N b, Mo , Cu, etc. should not impair the effects of the present invention. Yes.
- molten iron was produced as an amorphous base material, and Ti and A 1 were oxidized and purified.
- main raw material inexpensive steel scrap and Fe-B having the composition shown in Table 2 were used, and some Fe-Si was used for adjusting the Si concentration.
- the basic unit of the blending amount is also shown in Table 2. Table 2
- the temperature of the molten iron is raised to 1500 ° C.
- Table 3 the same iron ore used in the small experiment (Mount Newman: Iron content) 6 5 mass%), steelmaking dust (dust during decarburization treatment: iron 64 mass%), and sintered ore (58 mass% iron) after addition of 15 O kg (50 kg Xt) After 20 minutes, steel was produced.
- the molten iron component after melting is from 0.001% to 3% C, 0%.
- Table 4 shows the components of the molten iron sampled just before the iron oxide source was added and the components of the molten iron just before the steel was released.
- both T i and A 1 have a concentration reduced to less than 0.05% by weight which does not affect the magnetic properties. It was found that the oxidation loss of Si was small, and there was a yield of 95% or more based on the composition.
- Example 2 Use the same amount as the raw material used in Example 1, and charge the iron oxide source with an iron content of less than 55% by mass as shown in Table 5 into a 3-ton high-frequency melting furnace before melting. Went. When about 10 minutes had passed after the raw material melted, the temperature was measured and the molten iron was sampled. After the temperature was raised to 150 ° C., sampling was performed again to produce steel. For the purpose of improving the characteristics, by adding C, P, Co, Ni, and Cr to the main raw material, the molten iron component after melting becomes C 0. 0 0 8% or more 0.1.
- Table 6 also shows the components of the molten iron after melting and the components just before the steel starts.
- both T i and A 1 have no effect on the magnetic properties from the stage when the raw material is melted down, and the concentration is less than 0.05% by weight.
- the T i and A 1 concentrations decreased further in the steelmaking stage after the temperature rise.
- the oxidation loss of B and S i was small, and it was found that the yield with respect to the compounding composition of the pre-steel composition was 92% or more.
- an amorphous material can be produced at a low cost by efficiently removing A 1 and T i that deteriorate the magnetic properties. And became possible.
