Description of the invention () This invention relates to a batch of metal melt improver, which can be deoxidized (degassed) in the gold melt for casting. , Remove the inclusions, make the gold lute structure sound (even), mechanical properties (tensile strength, flexural strength and hardness, etc.) to give improved properties. In the metallurgical field, especially in the field where the raw metal needs to be melted or heated and then processed, there is a common problem, that is, the mixing of gases such as oxygen, deuterium, or hydrogen, or unnecessary The gray debris exists, and the golden tissue becomes non-uniform after solidification. In the field of binding, there is also the extraction of oxygen and other gases (generally referred to as deoxygenation) from the gold tantalum melt or the consolidation of the solidified metal group. In the past, iron ore metal was added with a monomer or compound powder that is easy to combine with oxygen and other monomers or compounds for deoxidation. In order to make the metal group sound, MFe-Si, Ca- The inoculant of Si and other main components. In addition, phosphorus compounds are added to the copper strip metal to remove the gas. An object of the present invention is to provide a metal melt improver that can solve the problems mentioned above, which have been a long-term problem in the casting field. The present inventors have conducted many studies to achieve the above-mentioned objectives, and learned that if they contain a treatment mixture made of a mixture of sulfide powder and silica-lime powder, they can be improved in the above-mentioned casting field. The nature of the invention is completed. (Feng first read the notes of the back. Matters need to be filled in.

Description of the invention () The special feature of the present invention is to use a mixture of iron sulfide powder and silica lime powder through heat treatment Although the reason why the treatment of the mixture is effective is unclear, the use of iron sulfide alone, silica lime alone, or simply mixing the two has no effect. The iron sulfide powder can be iron sulfide (FeaS) or sulfide. Ferrous iron (FeS), but it is better to use ferrous sulfide according to the price and ease of purchase. As for powder particles, the diameter M is about 100 ~ 300 mesh, preferably K is about 150 ~ 200¾ mesh. Silica lime It is also known as Wollastonite, a cyclic silicate of calcium, iron and manganese. In the present invention, the particle diameter is about 100 ~ 300 mesh, preferably about 150 ~ 200 mesh. Iron sulfide powder and silica lime powder The mixing ratio should be within 9 ~ 5: 1 ~ 5 weight ratio, if it can be 8 ~ 6: 2 ~ 4, it is better. Outside this range, it is more difficult to obtain certain properties. The heat treatment temperature is usually 300 ~ 750 = 0 If it can be 450 ~ 650t, it is better. Too low or too high may make the reaction incomplete. The treatment will vary depending on the object and purpose to be used, usually 1 ~ 10 hours, and 3 ~ 5 hours. It is advisable to use the inventive golden nugget improver, which will have excellent deoxidizing effect and improve the metal structure (homogenization) effect, and the inclusions will also be reduced. If it is a metal melt improver, except the above In addition to the treatment mixture, it is advisable to add carbon powder, silicon powder, aluminum powder, silicon oxide powder, aluminum oxide powder, ferrous oxide powder, iron powder, ferromanganese powder, fluorite, sulfonated silica powder sand, chlorpyrene , Copper powder, silica gel, sodium fluoride, etc., one or two of them are reconciled.

The combination of the components other than the above-mentioned mixture and the above-mentioned treatment mixture can especially remove oxygen from the molten molten iron, remove the inclusions M, and promote the soundness of the solidified gold scorpion group. If the target metal is a copper or copper alloy (such as bronze, etc.), for example, the above treatment mixture is 15 ~ 45%, such as 20 ~ 40% is more suitable, and copper powder lfl ~ 30%, such as 15 ~ 25% is more suitable , Gasification sodium 15 ~ 35%, such as 20 ~ 30% is more suitable, borax 5 ~ 15%, such as 7 ~ 12% is more suitable, ferrosilicon 1 ~ 5% * Printed by the Central Ministry of Economic Affairs of the Ministry of Economics and Agriculture Cooperative Print Compositions such as 2 to 4% are more suitable, ferromanganese 2 to 8%, such as 3 to 6%, and sodium fluoride%, such as 2 to 4% are more suitable. If such a%> good agent is used, the fluidity of the melt can be improved, and the heading effect can also be improved. The concave holes during shrinkage can be reduced, which can improve the mechanical properties, especially the elongation rate.

Description of the invention () The upper treatment mixture is 15 ~ 45%, preferably or 20 ~ 40%, the gasification sodium is 20% ~ 45%, preferably or 25 ~ 35%, and the sand is 1 ~ 10% by weight. Or 3 ~ 7%, sodium fluoride · 20 ~ 40% and preferably or 25 ~ 35% and the composition is more suitable. When adding such modifier, it can have excellent degassing effect, reduce casting shrinkage cavity and improve mechanical properties. When used as a metal melt improver, for 100 parts by weight of gold-tallow melt, it is preferable to add 0.1 to 0.7 parts by weight, or 0.3 to 0.5 parts by weight, if it contains 20 to 35% of the above treatment mixture. good. If it is added excessively, it is harmless but not economical, and if it is excessively insufficient, it tends not to be effective. There are various methods for adding the metal melt modifier. For example, it is a simple way to encapsulate the modifier in pins, copper and aluminum cans and put it into the melt, and it can be mixed uniformly. The available melt has less gas content, less inclusions, and improved fluidity. After solidification, the metal structure of the casting is uniform and sound, but the mechanical properties are disturbed. The following describes the improvement of the molten metal of the present invention based on manufacturing examples and examples, but the present invention is not limited to these examples.
