Abstract
The invention discloses a moss-shaped ferro-silicon-aluminum composite deoxygenation block for steelmaking. The moss-shaped ferro-silicon-aluminum composite deoxygenation block is characterized by comprising a ferro-silicon-aluminum moss-shaped block, the diameter of the bottom of the moss-shaped block ranges from 40 mm to 50 mm, and the height of the moss-shaped block ranges from 25 mm to 35 mm. When the ferro-silicon-aluminum composite deoxygenation block of the moss-shaped block is used, the contact area between the ferro-silicon-aluminum composite deoxygenation block and molten steel is large, the melting speed of the deoxygenation block can be increased, and the deoxygenation reaction process of the molten steel is facilitated.
Description
Technical field
The present invention relates to a kind of steel-making tongue shape ferro-silicon-aluminium composite deoxidation block.
Background technology
The production of aluminium and use procedure can produce considerable number of waste aluminum, the aluminum content that steel-making aluminium ingot standard specifies is lower than the aluminum content of primary aluminium ingot, therefore available waste aluminum makes deoxidizer in steel production, and waste aluminum is carried out regeneration, and tool is of great significance.
The Main Function of deoxidant for steelmaking is to react with the oxygen of dissolving in molten iron, mainly generates nonmetallic compound, forms precipitation and float up in slag blanket, the molten iron being removed pure.Aluminum is as deoxidizer, grain refiner and alloy addition in process for making, and its application form is aluminum steel (injection feeding technology), little aluminium ingot, aluminum ring, aluminum cake (throw-in play), aluminum shot, aluminium bomb (shooting method), ferro-aluminum block, aluminum silicon barium iron block (complex deoxidization method) etc..Existing aluminum steel is usually cable factory and utilizes primary aluminium ingot to take melting, extruding or rolling mill practice to produce, and the outer primary aluminium ingot making such as deoxidation aluminium ingot, aluminum ring and the utilization of Lv Bingshi steel mill, ferro-silicon-aluminium and aluminum barium ferrum utilize mineral hot furnace to produce.
Summary of the invention
It is an object of the invention to provide a kind of steel-making tongue shape ferro-silicon-aluminium composite deoxidation block.
Technical problem solved by the invention can realize by the following technical solutions.
Steel-making tongue shape ferro-silicon-aluminium composite deoxidation block, it is characterised in that include the tongue shape block of a ferro-silicon-aluminium matter, described tongue
The base diameter of shape block is 40mm～50mm, and the height of described tongue shape block is 25mm～35mm.
The beneficial effects of the present invention is, the ferro-silicon-aluminium composite deoxidation block of this tongue shape block is big with the contact area of molten steel in use, can accelerate the burn-off rate of deoxidation block, be conducive to the deoxygenation process of molten steel.
Accompanying drawing explanation
Fig. 1 is that the present invention makes steel with the structural representation of tongue shape ferro-silicon-aluminium composite deoxidation block.
Detailed description of the invention
For the technological means making the present invention realize, creation characteristic, reach purpose and effect and be easy to understand, below in conjunction with being specifically illustrating, the present invention is expanded on further.
Shown in Figure 1, steel-making includes the tongue shape block 100 of a ferro-silicon-aluminium matter with tongue shape ferro-silicon-aluminium composite deoxidation block, and the base diameter of described tongue shape block 100 is 40mm～50mm, and the height of described tongue shape block 100 is 25mm～35mm.
During use, the ferro-silicon-aluminium composite deoxidation block of this tongue shape block is big with the contact area of molten steel in use, can add
The burn-off rate of fast deoxidation block, is conducive to the deoxygenation process of molten steel.
The ultimate principle of the present invention and principal character and advantages of the present invention have more than been shown and described.Skilled person will appreciate that of the industry; the present invention is not restricted to the described embodiments; described in above-described embodiment and description is that principles of the invention is described; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements both fall within the claimed scope of the invention.Claimed scope is defined by appending claims and equivalent thereof.
