Description
Technical field
The present invention relates to a kind of anti-oxidation reducing agent, refer in particular to a kind of molten metal oxidation resisting and reducing agent.
Background technology
In the industrial production, regular meeting relates to a kind of metal or alloy of fusion, the technology that makes itself and another kind of melts combine or adhere to.Because most metals contact with oxygen all can oxidation, getting rusty as iron promptly is the modal example of oxidation.Under hot environment, especially under melting state, the situation of metal (or alloy) oxidation can be more violent, can form one deck oxide compound very soon, and poly-more many more.And adhere in the bonded technological process at molten metal and other metals, the flow circuit that molten metal must not stop, this can aggravate oxidation rate on the one hand, means that on the other hand the oxide compound on top layer and a spot of oxygen can be brought to below the liquid level, i.e. liquid internal.Oxidation can take place equally in inside so.Oxide compound will be carried the floating liquid level of going up of good metal secretly like this, form scum silica frost.Because the generation that do not stop of scum silica frost, emersion causes the scum silica frost accumulation more and more, and is folded, more and more thicker mutually layer by layer, influence liquid level after several hours and flows, even produce excessively, pollutes danger again.The scum silica frost that is produced can not normally participate in the production process that merges, can only constantly salvage out otherwise processed.Because of after salvaging scum silica frost, liquid level is not enough, even it is not enough to produce consumption, can only ceaselessly add and replenish new raw metal.
For this reason, for avoid the molten metal oxidation as far as possible, need molten metal is carried out antioxidation treatment, at present, existing antioxidation processing technology mainly contains reductive agent reduction method, reduction machine facture, fills nitrogen insulation blocking method etc.Wherein increase reductive agent and reduce antioxidation method and adopt comparatively extensively, reductive agent commonly used has the gluey reducing substance of reducing powder, reducing metal and thickness etc.
Wherein, the employing reducing powder carries out the reductive mode of operation and is: at the molten metal fluid surface, sow flour, its deficiency or limitation performance are as follows:
A: use very inconvenience of form, because it is a flour, it is very not easy to operate to make an addition to the high-temperature molten metal surface, for the bigger liquid level of surface area, want to sow and evenly note again not ironed by high temperature, must be very careful, so use extremely inconvenience.
B: disperse easily, thereby cause waste and pollute,, and ventilation plant is arranged all generally above the molten metal liquid level, as sow and improper generation is dispersed, cause waste and pollute because be the dryness flour.
C: smog is bigger, and reducing powder is generally acid, alkali, salts substances, with after the molten metal liquid level contacts can and other auxiliary agents reactions, the back smog that is heated is bigger, original ventilation plant is not enough to wind is drained.
D: hazardness is bigger, as mentioned above, because of it is acid, alkali, salts substances, to human body, equipment, environment all have certain harm, calculate the saving of its effect back reduzate, and economic worth is not high.
And adopt the operating principle of reduction particle (metal) to be: in or the metal that mix identical with molten metal, add high-purity activity material (as reducing powder), cooling forming is made metallic particles (or metal segments), adds and molten metal liquid during use.Its weak point have following some:
A: costliness, from its preparation form promptly as can be known,, add actives because of having passed through the metal fusion, operations such as moulding, Master Cost and processing charges are all very high.
B: use-pattern is optimized inadequately, during use, drops in proportion in the molten metal liquid, allows metallic particles melt, and separates out reducing substance, recurrence reduction and anti-oxidation effect.Because of fusing needs a time, after separating out, actives is dissolved in metal liquid, spread evenly also non-easy thing rapidly.
C: alloy content changes than regular meeting, and not necessarily in full accord with the work alloy because of the metallic particles alloy ratio, the long-term input can change work alloy content ratio, and this sometimes change can bring serious quality consequence.
D: certain side effect is arranged, and wayward because of consumption requires accurately, because of production line is not balanced especially, it is excessive that some particle uses, and except causing waste, also can make work molten alloy tension force become big, on the contrary in conjunction with adhere to downgrade.
The method that adopts the gluey reducing substance of thickness is that more external companies release.Its principle of work is, adds active substance in viscous liquid, pours the molten metal liquid level during use into, through fully stirring, is spread in fluid surface, forms protective membrane, and continues to take place reductive action.Its limitation be following some:
A: spread rapidly inadequately, must effort stir.
B: viscosity is excessive, and regular meeting is attached to workpiece, causes product contamination, is difficult to clean.
C: the residual and molten metal mixture of its viscosity, in the flow of molten metal circulation, be attached to equipment unit, cause equipment circulation passage obstruction, not smooth, bring inconvenience to maintenance of the equipment.
D: throw out, stick at equipment unit, be similar to the resin type hard material, cleaning is difficulty very.Very inconvenience of corrective maintenance cleaning, in the long run, damage equipment is bound to.
