执行标准/Operative Norm: Q/LYZT 002-2012



由于国家对电解铝行业生产规模和环保指标的控制,国内电解铝各企业围绕节能降耗,改善环境和技术进步竞争激烈。为了适应国内电解铝行业的技术改造,我公司和有关电解铝行业专家、技术人员于2000年7月共同开发研制出一种新产品“磷生铁”。该产品是将铸造生铁的五大成份碳、硅、硫、磷、锰控制在符合电解铝阳极浇注的各项指标和工艺技术要求范围内。改变了以往用磷铁、硅铁、锰铁、生铁的混合配料工艺。经近年来的使用,效果显著,得到了电解铝行业专家和工程技术人员的一致好评。产品国内用户占有率达50%以上,并出口马来西亚、哈萨克斯坦、越南等国家。

Since the state control of the scale of production and environmental indicators for the aluminum industry,domestic electrolytic aluminum enterprises have a fierce competition focus on saving energy,improving environment and technology.In order to adapt to the technological transformation of the domestic aluminum industry, our company cooperated with related experts and technical staff in aluminum industry,developed a new product called phosphorus pig iron in July 2000. The product is cast iron of Five components which are carbon,silicon,sulfur,phosphorus, manganese are controlled in the range of various indicators and technology requirements of anodic aluminum casting,which changed the mixed ingredients processes with phosphorus iron,ferrosilicon,ferromanganese and pig iron in the past.By practical use,the effect is significant in recent years,which got high praise of aluminum industry experts and engineering technicians.Products share over 50% of domestic users,and export to Malaysia, Kazakhstan,Vietnam and other countries.


该产品属电解铝厂阳极钢爪和阳极碳块浇注连接固定专用磷生铁,它对中频炉、工频炉、冲天炉均能适应。

This product is special phosphorus iron for the electrolytic aluminum anode steel claw and anode carbon block casting connections,it can adapt to intermediate frequency furnace,power frequency furnace and cupola.



化学成分也可根据各企业实际情况要求配比生产

Chemical composition can be produced by ratio according to the actual circumstance of enterprise’s requirements.


磷生铁因不需再进行磷铁、硅铁、锰铁、生铁的混合配比,这不但使阳极浇注工序简化,省时、省力,而且解决了硅铁、磷铁、锰铁因风化,破碎产生粉末及入炉后的氧化、挥发造成的损耗和污染问题。对文明生产、环境达标有不可替代作用。

专用磷生铁五大元素含量稳定准确。比组配工艺可降低熔点100-150℃左右,并能使每炉熔化时间缩短15分钟。从而节省电力、燃料,提高了工作效率。

专用磷生铁在电解槽使用过程中,能使铁碳压降全系列稳定一致,便于电解生产技术条件的调整,给各经济技术指标的稳定提高奠定了基础。

使用磷生铁,熔化浇注时,流动性好,浇口饱满平滑,冷却后反石墨化优点突出,容易脱离。常年使用该产品,可延长钢爪使用寿命。

对钢爪材质和碳素材质均有良好的粘接强度,保证在电解过程中避免阳极的脱落。

Phosphorus pig iron do not need to be mixed with ferrophosphorus,ferrosilicon, ferromanganese, and pig iron by ratio,which not only simplifies the anode casting process,saving time and effort,and to solve the problem of powder caused by efflorescence,broken of ferrosilicon,ferrophosphorus and manganese,cost and pollution caused by oxidation and volatilization.It played irreplaceable role for civilization production and environmental compliance.

The content of five elements in phosphorus pig iron are stable and accurate. Compared with the group process,100-150 ℃ of the melting point can be reduced, and 15 minutes of each furnace melting time can be shortened,thus saving electricity, fuel and improving work efficiency.

The process of special phosphorus cast iron used in electrolytic cell can make the iron carbon pressure drop in the whole series stable and consistent.It’s  advantageous for the adjustment of electrolytic production technology conditions and it laid a solid foundation to the stable improvement of the economic and technical index.

When using phosphorus iron for casting, It’s with good liquidity,pouring flat and smooth.Anti graphitization advantage is significant after cooling and easy to remove.It can prolong the service life of the steel talons if the long term use of the product.

It has good adhesive strength the material of the steel claw and the carbon,so that to ensure to avoid loss of the anode during the electrolysis .


1、磷生铁的循环使用周期关键在于阳极组装车间的细化管理及责任心,前两三次的使用,各元素基本保持在规定的指标范围内,之后若干次的使用在保证磷生铁正常状态下,每次高温熔化过程中各元素都有新的变化,根据各元素变化的多少来调控磷生铁和磷铁环的投炉循环使用比例,比如磷生铁与磷铁环的比例为2∶8 3∶7 5∶5 6∶4 7∶3……这样即保证铁水的流动性好又使磷生铁各元素保持良好指标。

2、磷生铁与磷铁环配比铁水中碳含量过低可加入专用增碳剂,提高碳的含量,硫含量超出范围,加入专用脱硫剂,使硫控制在规定范围。加入量根据生铁中碳、硫的含量而定。

3、磷生铁与磷铁环配比熔炼中难免杂质过大,可采用专用除渣剂去除杂质,提高浇铸质量、合格率。

The use of regulation when recycled use of phosphorus pig iron and phosphorus hoop  

ng to the actual circumstance of enterprise’s requirements.


1.The key to phosphorus pig iron recycle period is the fine management and sense of responsibility of anode assembly shop,the basic content of each element will keep within the scope of the regulation of index in the use of first two or three times, after several times of using,each element has new change in high temperature melting process while the state of phosphorus iron is normal.The recycle usage ratio of phosphorus pig iron and phosphorus iron ring is decided according to the changes in the elements of phosphorus iron,such as the proportion of phosphorus iron and phosphorus iron ring is 2:8 3:7, 5:5 6:4 7:3...It can guarantee good liquidity of molten iron and keep each element of phosphorus iron with good indicator.

2.If the carbon content in molten iron with proportion of phosphorus pig iron and phosphorus iron hoop is low,special carburant can be added in it to increase the content of carbon,and if sulfur content beyond the scope,add the dedicated desulfurizer and sulphur can be controlled within the prescribed scope.The adding amount is up to the content of carbon and sulfur in phosphorus iron.

3.Special cleaner agent can be added to avoid excessive impurities in the melting of phosphorus iron and phosphorus iron ring in proportion,thus improving casting quality and qualified rate.
