Description
Technical field
The invention belongs to non-ferrous metal metallurgy specific purpose tool technical fields, and in particular to one kind is used for electrolytic cell, intermediate frequency furnace
Smelt the fire-resistant oxidation resistant slag wooden dipper of slag hitting.
Background technique
Slag wooden dipper is the important slagging-off tool of slag hitting operation in nonferrous metallurgical process, at present the electrolytic cell of aluminium industry,
It is widely used in intermediate frequency furnace production work.The slag wooden dipper that the prior art uses is the plane slag shovel board made of Q235 material,
Q235 material is carbon containing moderate, and comprehensive comparison is good, and intensity, plasticity and welding performance are preferably cooperated, and fusing point is 1495
DEG C or more.At 950 DEG C -970 DEG C, the two poles of the earth are chemically reacted in electrolytic cell, that is, are electrolysed, and Q235 material slag wooden dipper can generate at this time
Quickly oxidation and part are melted, and slag wooden dipper consumption is huge, and tool use cost increases.Meanwhile the iron after thawing is mixed into molten aluminum,
Cause molten aluminum iron content to increase (key index that iron content is aluminium grade), directly reduces the quality of aluminium product.Intermediate frequency
For furnace smelting molten iron temperature at 1450 DEG C or more, slag wooden dipper scaling loss is larger, and melting one furnace molten steel consumption, 2 pieces of slag shovel boards lead to Work tool
Consuming cost is high, and operator needs to constantly change slag wooden dipper, and the production of slag wooden dipper and maintenance cost are higher.In addition, flat
Face shovel slag plate slagging-off effect is bad, and slagging-off efficiency is lower.
Summary of the invention
Present invention aims to solve the deficiencies of the prior art, and provides a kind of one kind to be not easy to melt, long service life, can repeatedly follow
Ring uses, and reduces tool consumption and production and maintenance cost, and can avoid the iron after fusing and be mixed into reduction aluminium product matter in molten aluminum
It measures and what slagging-off was high-efficient is used for non-ferrous metal metallurgy slag hitting fire-resistant oxidation resistant niobium alloy slag wooden dipper.
The purpose of the present invention is achieved through the following technical solutions:
One kind being used for non-ferrous metal metallurgy slag hitting fire-resistant oxidation resistant niobium alloy slag wooden dipper, and the slag wooden dipper is spoon shape structure,
Including wooden dipper body and wooden dipper handle, leak hole is offered in wooden dipper body bottom；The wooden dipper body and wooden dipper handle are made of fire-resistant oxidation resistant niobium alloy,
The fire-resistant oxidation resistant niobium alloy is Nb-1Zr；Surface is sprayed fire-resistant oxidation resistant coating material in wooden dipper body and wooden dipper, it is described
Fire-resistant oxidation resistant coating material is MoSi2。
The present invention is machined with outer end in wooden dipper can the external mounting hole for lengthening wooden dipper handle.Multiple leakages are offered in wooden dipper body bottom
Hole, including the multiple leak holes for being located at the center leak hole of wooden dipper bottom center minimum point and being uniformly arranged around center leak hole.
The fusing point of fire-resistant oxidation resistant niobium alloy of the present invention is 2467 DEG C, in 1093 DEG C of -1427 DEG C of temperature ranges
It is able to maintain higher-strength, plasticity is good, and processing performance is excellent.But since niobium alloy is in 600 DEG C or so meeting accelerated oxidations, this hair
It is bright to spray MoSi on slag wooden dipper surface2Fire-resistant oxidation resistant coating material can make oxidizing temperature be promoted to 1450 DEG C -1600 DEG C, keep away
Exempt from effectively to be solved prior art slag wooden dipper by severe oxidation and fusing and easily melted the deficiency of loss, and avoid prior art fusing
Iron afterwards is mixed into molten aluminum the problem of reducing aluminium product quality.
Slag wooden dipper of the present invention is using spoon shape structure rather than the grafter structure of the prior art, wooden dipper body can more scoop up slag,
Molten metal can be leaked down by improving slagging-off ability and efficiency, the leak hole of wooden dipper body bottom, prevented from taking molten metal out of when slagging-off and caused wave
Take.The wooden dipper outer end be machined with can external lengthening handle mounting hole, be conveniently replaceable, avoid existing shovel slag plate and shovel and use
The production of welding structure bring is troublesome and wastes big drawback.
Detailed description of the invention
Fig. 1 is the structural schematic diagram that slag wooden dipper of the present invention is overlooked；
Fig. 2 is the Section A-A figure of Fig. 1.
Specific embodiment
Below in conjunction with attached drawing, the present invention is further described.
As shown in Figure 1 and Figure 2, a kind of to be used for non-ferrous metal metallurgy slag hitting fire-resistant oxidation resistant niobium alloy slag wooden dipper, the slag
Wooden dipper is spoon shape structure, including wooden dipper body 1 and wooden dipper offer leak hole 3 in wooden dipper body bottom 2, and outer end is machined with and external can be added in wooden dipper
The mounting hole 4 of long wooden dipper handle is replaced in order to slag wooden dipper and is used, saves welding sequence.The present embodiment wooden dipper is 200mm design length,
Contact molten metal liquid level in operating process is avoided to be burnt fusing, outer end is offered 3 11 mounting holes of Φ by wooden dipper, is connected for bolt
It connects and lengthens wooden dipper handle.Multiple leak holes 3 are offered in wooden dipper body bottom, including being located at the center leak hole of wooden dipper bottom center minimum point and in
Multiple leak holes that heart leak hole is uniformly arranged, the present embodiment has opened up 7 14 leak holes of Φ, convenient for the filtering of carbon metal in the dreg liquid, wooden dipper
Negative camber inclination angle is conducive to slag and faster separates with molten iron, reduces cost of material.The present invention makes wooden dipper body 1 and wooden dipper, and 2 plate is thick
Degree only needs 6mm, and the shovel slag plate that plate thickness compared with prior art is 8mm reduces tool weight, saves material, can subtract
Light labor intensity of workers, raises labour productivity.
Being made of fire-resistant oxidation resistant niobium alloy, the fire-resistant oxidation resistant niobium alloy is for wooden dipper body of the invention and wooden dipper
Nb-1Zr.Surface is sprayed fire-resistant oxidation resistant coating material in wooden dipper body and wooden dipper, the fire-resistant oxidation resistant coating material is
MoSi2.Nb-1Zr and MoSi2It is prior art material.
