Abstract
The present invention relates to a silicon-aluminium-barium alloy for steel-making and its production method. The element contents of said alloy are (wt%) 28-40 of silicon, 15-30 of aluminium , 12-20 of barium, and rest is iron. In its production process the charging sequence is changed into steel cuttings, silicobarium alloy and aluminium ingot, and after said metal is molten in the course of smelting, a layer of thin slag is made on its surface, and at the same time its tapping temp. is controlled in about 1200 deg.C.
Description
The present invention relates to a kind of steel-making silicon-aluminium-barium alloy and preparation method thereof.
In the process for making process, the reductor of steel-making final deoxygenation is generally served as by aluminium, but because the price of metallic aluminium is higher, so improved the cost of steel-making.For cost is reduced, Iron And Steel Company seeks the surrogate of aluminium one after another both at home and abroad, but the deoxidation of generally adopting at present is still higher with silicon-aluminium-barium alloy and aluminium that making processes consumes thereof, and can not fully satisfy the needs that reduce steel-making cost.
Make silicon-aluminium-barium alloy at present and generally smelt as raw material, then casting with the material of siliceous, aluminium, barium.Wherein element recovery rate is meant:
Element recovery rate is a parameter that is subjected to multiple factor affecting, and rate of recovery height means the prepared using height, thereby reduces production costs.But because of reasons such as working condition, technologies, the rate of recovery can not infinitely improve, and owing to different element proportions in the alloy have the certain limit restriction, thereby also certain element recovery rate can not be carried very high.Therefore, how totally to improve each element recovery rate, both made alloy meet steel-making requirements, reduced consumption of raw materials again, just become the last outstanding problem in the silicon-aluminium-barium alloy production.
Traditional alloy smelting technology is divided into batching, induction furnace smelting, casting, opens four steps such as mould finishing.In the induction furnace smelting process, its order of addition(of ingredients) is: aluminium, Si-Ba alloy, steel cuttings; Tapping temperature is 1300 ℃ or higher; And on melt metal the unprotect layer, metal is directly contacted with air.This method makes production cost high because effect such as element volatilization and oxidation under the high temperature reduces each element recovery rate greatly.
The object of the present invention is to provide a kind of sial barium of making steel usefulness to close unanimous and production method.This alloy can play the effect of substitution of Al as reductor, can effectively reduce the consumption of aluminium again, reaches the effect that reduces steel-making cost, and this method can effectively improve the rate of recovery of elements such as silicon in the alloy, aluminium, barium.
The object of the present invention is achieved like this: the silicon-aluminium-barium alloy that a kind of deoxidation in steel making is used, wherein contain silicon, aluminium, barium, iron, and to count by weight percentage, their proportions in alloy are (%): silicon 28-40, aluminium 15-30, barium 12-20, surplus is an iron.
Above-mentioned silicon-aluminium-barium alloy, its production technique key step is: (1) batching, (2) induction furnace is smelted, (3) casting, (4) open the mould finishing, it is characterized in that, and step (2) is:
A, a certain proportion of Si-Ba alloy, aluminium ingot, steel cuttings are pressed steel cuttings, Si-Ba alloy, the order of aluminium ingot adds induction furnace;
Behind B, the metal melting, make thin slag one deck thereon;
C, alloy are 1150 ℃-1250 ℃ from the tapping temperature of induction furnace.
General alloy production processing step comprises batching, induction furnace smelting, casting, opens four steps of mould finishing.Following processing: a is made in the present invention general smelting wherein, change order of addition(of ingredients) is steel cuttings, Si-Ba alloy, aluminium ingot; B, when smelting, make the skim covering slag; Can reduce the burning amount like this, reduce the loss of metallic element; C, tapping temperature is reduced to about 1200 ℃ by original 1300 ℃, this has also reduced the loss that element oxidation and volatilization cause effectively.Use the present invention to produce alloy, each element recovery rate height has reduced production cost effectively.Its aluminum content of the alloy of this invention reaches the deoxidation in steel making requirement, replace aluminium to make the steel-making end-deoxidizer with this alloy, can make in the steel with the aluminium sesquioxide to be that the large-scale inclusion of matrix obviously reduces, thereby significantly reduce the casting nozzle dross, help normally the carrying out of continuous casting process of steel.
Claims (2)
1, the silicon-aluminium-barium alloy used of a kind of deoxidation in steel making wherein contains silicon, aluminium, barium, iron, counts by weight percentage, and their proportions in alloy are (%): silicon 28-40, and aluminium 15-30, barium 12-20, surplus is an iron.
2, silicon-aluminium-barium alloy according to claim 1, its production technique key step is: (1) batching, (2) induction furnace is smelted, (3) casting, (4) open the mould finishing, it is characterized in that, and step (2) is:
A, a certain proportion of Si-Ba alloy, aluminium ingot, steel cuttings are pressed steel cuttings, Si-Ba alloy, the order of aluminium ingot adds induction furnace;
Behind B, the metal melting, make thin slag one deck thereon;
C, alloy are 1150 ℃-1250 ℃ from the tapping temperature of induction furnace.
