Abstract
A nodulizer for cored wire used for nodulizing the nodular cast iron is prepared from Mg ingot, Si-Ca alloy, Si-Ba alloy, rare-earth Si-Fe alloy and ferrosilicon 75 through smelting and crushing. It contains Mg (15-28%), Ca (0-10%), Ba (0-10%), rare-earth (5-20%), Si (30-80%) and Fe (rest). Its advantages include low cost, smooth nodulizing reaction, stable nodulized quality, high Mg-absorbing rate and less environmental pollution.
Description
The present invention relates to a kind of iron alloy product, it belongs to the used alloy material of spheroidizing in the spheroidal graphite cast iron production process.
In the production process of spheroidal graphite cast iron, spheroidizing is a requisite link.In the prior art, generally adopt rare earth magnesium ferrosilicon alloy to pour method in China's spheroidizing and handle.Though its process is easy, the specific absorption of magnesium is not high, particularly causes nodularization quality instability because of the nodularization process is difficult to control, and produces serious environment pollutions such as intensive magnesium light, smog in the spheroidizing process.The cored-wire wire-feeding technique is a kind of simple and effective method of adding various alloys or additive in metal melt, is a kind of important external refining means in the Iron And Steel Industry.In recent years some casting expert attempts this technology introducing foundry industry as the new tool that adds magnesium or contain magnesium alloy in molten iron.The result of test shows: have that nodularization steady quality, nodularization process are controlled easily, environmental pollution reduces and many advantages such as spheroidizing cost reduction with cored-wire cored wire injection nodulizing processing.Because the cored wire injection nodulizing treatment technology is in the starting stage in China, the nodulizing agent that cored wire injection nodulizing plays an important role in handling fails to obtain due attention, and not seeing has the special-purpose nodulizing agent of developing at the characteristics of cored wire injection nodulizing.It is lower that the nodulizing agent that is used to the method that pours contains magnesium, though it is used for cored wire injection nodulizing reacting balance, magnesium absorption rate height, the cored wire injection nodulizing cost is too high; Join the nodulizing agent that a certain amount of ferrosilicon or silico-calcium are handled as line feeding with pure magnesium line or pure magnesium powder, though the cost problem is solved, spheroidizing reacion is still too fierce, and splashing of magnesium light, molten iron is difficult to avoid.The ideal line feeding should guarantee that the cored wire injection nodulizing total cost has under the prerequisite of certain advantage, makes spheroidizing reacion steady, thereby makes specific absorption height, light and the cigarette etc. of nodularization steady quality, magnesium little to the pollution of environment with nodulizing agent.
The objective of the invention is at the deficiencies in the prior art and problem, provide a kind of adapt to the cored wire injection nodulizing processing feature and have that cost is low, spheroidizing reacion steadily, the specific absorption height of nodularization steady quality, magnesium, have forming core inoculation(effect), light and cigarette etc. that the little cored wire injection nodulizing of the pollution of environment is handled special-purpose nodulizing agent.
The composition of the said nodulizer for cored wire of the present invention is: magnesium 15~28%, and calcium 0~10%, barium 0~10%, rare earth 5~20%, silicon 30~80%, all the other are iron.
With magnesium ingot, silicocalcium, Si-Ba alloy, rare earth ferrosilicon alloy, 75 ferrosilicon etc. is raw material, determines proportioning raw materials by above-mentioned element ratio, smelts by pouring the identical method of method nodulizing agent with routine.Below Mechanical Crushing to 5 millimeter, be used to make cored-wire.
The said nodulizer for cored wire of the present invention adopts the alloy form through smelting, because the magnesium in the nodulizing agent is with Mg
2The Si form exists, make magnesium gasification, burning, reactively compare and can reduce greatly with pure magnesium, when spheroidizing with use identical Mg content, but magnesium compares with the nodulizing agent that element state exists, its spheroidizing reacion is more steady, and and then makes the specific absorption raising of magnesium.
The said nodulizing agent of the present invention has been owing to adopted rational Mg content, both guaranteed that the cost that cored wire injection nodulizing handles was unlikely too high, make again nodulizing agent can be under normal condition routinely technology smelt.The overgenerous magnesium light of unlikely generation, smog and molten iron splashed when reasonably Mg content had also guaranteed spheroidizing.
The element proportioning of the said nodulizer for cored wire of the present invention can guarantee that nodulizing agent has nodularization effect preferably, anti-ageing effect, anti-interference effect and the pregnant effect of moving back.
That below provide is an embodiment: with magnesium ingot, rare earth ferrosilicon, 75 ferrosilicon is raw material, in magnesium 20%, rare earth 9%, determine the ratio of magnesium ingot and rare earth ferrosilicon, the not enough benefit with 75 ferrosilicon, and the scaling loss of adequate compensation magnesium when melting.The nodulizing agent melting technology is smelted routinely in 150 kilograms of medium-frequency induction furnaces.Nodulizing agent is used to make cored-wire below Mechanical Crushing to 5 millimeter.
The present invention also can be at the characteristic of base iron, as what of the height of sulfur content, interference element, is that cupola furnace molten iron or electric furnace molten iron etc. are adjusted in the mentioned component scope the nodulizing agent composition, makes the special-purpose nodulizing agent at specific working condition.
