Description
Technical field
The present invention relates to a kind of refining furnace microalloy adding apparatus and its Adding Way, belongs to metallurgy industry refining equipment skill
Art field.
Background technology
, it is necessary to add trace element in special steel smelting process, because micro- addition is small, cost is high, and easily
Reacted with top slag, cause microalloy to not easily pass through top slag blanket and reach molten steel, reduce the recovery rate of trace element, cause micro-
The increase of alloy usage amount is measured, cost improves.
To improve the recovery rate of trace element, cost is reduced, most efficient method is to avoid pushing up slag blanket, directly by micro conjunction
Gold is added in molten steel.
At present, add the method for trace alloying element mainly have it is following two：First, RH application of vacuum process is used, true
Microalloy is directly added into molten steel by empty room, second, the addition of the microalloy for no RH equipment, using open band
Flat cylindrical vessel adds, and this opening is with flat cylindrical vessel, because bottom area is big, so by molten steel and steel
The buoyancy of slag is big, and molten steel difficulty is pressed into when causing to add, and because top is open, causes microalloy oxidation in adition process tight
Again, it is low to ultimately result in the recovery rate of trace element, usage amount increase, cost improves.
The content of the invention
It is an object of the present invention to provide a kind of refining furnace microalloy adding apparatus and its Adding Way, can prevent micro conjunction completely
Gold and top slag reaction, reduce oxidation by air amount, improve the recovery rate of microalloy, reduce usage amount, reduce smelting cost, solve
Problem present in background technology.
The technical scheme is that：
A kind of refining furnace microalloy adding apparatus, include cylindrical drum, handle, taper cone barrel, end cap and steam vent, the bottom of cylindrical drum
It is fixedly connected with taper cone barrel into a single integrated structure, the top of cylindrical drum is provided with end cap, and the end cap is in disk form, and end cap is provided with more
Individual steam vent, handle are fixed in cylindrical drum.
The cylindrical drum and taper cone barrel are that stainless steel plate is welded.
The wall thickness of the cylindrical drum is more than the wall thickness of taper cone barrel.
Multiple steam vents on the end cap are evenly arranged.
A kind of refining furnace microalloy Adding Way, using above-mentioned limited refining furnace microalloy adding apparatus, comprising with
Lower step：
1. microalloy is added in cylindrical drum and taper cone barrel, and cover end cap；
2. hand-held handle, the top slag blanket in refining furnace is broken using taper cone barrel, and taper cone barrel is inserted into the molten steel in refining furnace
In；
After 3. taper cone barrel is melted, microalloy is naturally fallen in the molten steel in refining furnace.
The beneficial effects of the invention are as follows：Microalloy and top slag reaction can be prevented completely, oxidation by air amount is reduced, carry
The recovery rate of high microalloy, usage amount is reduced, reduce smelting cost, simple to operate, strong applicability, and taper cone barrel is fused to molten steel
It is interior, molten steel will not be polluted.
Brief description of the drawings
Fig. 1 is schematic structural view of the invention；
In figure：Cylindrical drum 1, handle 2, taper cone barrel 3, end cap 4, steam vent 5.
Embodiment
Below in conjunction with accompanying drawing, by example, the invention will be further described.
Referring to the drawings 1, a kind of refining furnace microalloy adding apparatus, cylindrical drum 1, handle 2, taper cone barrel 3, the and of end cap 4 are included
Steam vent 5, the bottom of cylindrical drum 1 are fixedly connected into a single integrated structure with taper cone barrel 3, and the top of cylindrical drum 1 is provided with end cap 4, described
End cap 4 is in disk form, and end cap 4 is provided with multiple steam vents 5, and handle 2 is fixed in cylindrical drum 1.
A kind of refining furnace microalloy Adding Way, using above-mentioned refining furnace microalloy adding apparatus, comprise the steps of：
1. microalloy is added in cylindrical drum 1 and taper cone barrel 3, and cover end cap 4；
2. hand-held handle 2, the top slag blanket in refining furnace is broken using taper cone barrel 3, and taper cone barrel 3 is inserted into the steel in refining furnace
In water；
After 3. taper cone barrel 3 is melted, microalloy is naturally fallen in the molten steel in refining furnace.
In the present embodiment, cylindrical drum 1 is welded by 2mm stainless sheet steel, 1 high 200mm of cylindrical drum, external diameter
200mm.Taper cone barrel 3 is welded by 5mm stainless steel thick plate, and the maximum outside diameter of taper cone barrel 3 is 200mm, is highly 150mm,
Taper cone barrel 3 can quick penetration top slag blanket, and do not melted by top slag.End cap 4 is made by 5mm general steel plates, and the external diameter of end cap 4 is
190mm, multiple steam vents 5 on end cap 4 are symmetrically arranged, a diameter of 2mm, both can guarantee that the expanded by heating gas in device
Smoothly discharge, and can ensure microalloy and air relative insulation inside device.Handle 2 is by 4 points of steel pipe manufacturings, a length of 2 meters.
In refining process, 5Kg microalloys are added in cylindrical drum 1 and taper cone barrel 3, cover end cap 4, hand-held handle 2,
By the cone of taper cone barrel 3 down, top slag blanket is broken rapidly, is inserted inside molten steel, and after molten steel fusing taper cone barrel 3, microalloy melts
Change and enter in molten steel.Prevent microalloy and top slag reaction completely, reduce oxidation by air amount, and only taper cone barrel 3 is molten
In in molten steel, molten steel will not also be polluted.
