产品介绍：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***、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，***，得到了电解铝***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Because of country control electrolytic aluminium industry production scale and of the environmental protection index, every electrolytic aluminium industry lowering energy consumption , improve the environment and technical progress. Is for the update the technology, our company research and development new product “Phosphorus pig iron” with electrolytic aluminium specialist in 2000. The product is casting of the five element(C, Si, S, P, Mn) will composition control in compliance with the cast aluminum anodes of each index and technical requirements of range. Change with phosphorus iron ferrosilicon ferromanganese pig iron mixed ingredients process. Effective etc, get the praise of the aluminum experts. Domestic user up to 50%, and exports Malaysia, KZ, Vietnam.适用范围： 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。Used for anode steel talons and anode carbon block casting fixed, accommodate of intermediate frequency furnace, line frequency furnace and cupola.磷生铁型号及化学成分/Chemical composition 产品特点及效果1、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***作用。2、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。3、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。4、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。5、对钢爪材质和碳素材质均有良好的粘接强度，***在电解过程中避免阳极的脱落。1.No need mixing ratio with Ferro phosphorus, ferrosilicon, ferromanganese, pig iron, the anode pouring process simplified, save time, save effort, solve the problem of the loss and pollution.2.Five element content stable and accurate. Lower melting point 100-150, melting time shorten 15 minutes. Saving electric power, fuel.3.Make the iron carbon pressure drop all series consistency, facilitate adjustment technology.4.Easy flow , sprue smooth , after cooling the graphitization outstanding merits, easy separate.5.Have good adhesive strength, avoid anode drop.磷生铁与磷铁环循环使用时的调控使用方法Phosphorus pig iron and phosphorus hoop recycling regulated by the method1、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***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***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。1. Phosphorus pig iron cycle life cycle of the key is the refinement of the anode assembly plant management and accountability, two or three times before use, the elements remained in the specified target range, after a number of the use of phosphorus pig iron normal state each high-temperature melting process elements have a new change, the proportion of each element the number of changes to the regulation of phosphorus pig iron and phosphorus hoop cast furnace cycle, such as phosphorus pig iron and phosphorus hoop ratio of 2:8 3 : 7 5:5 6:4 7:3 ... so that to ensure the fluidity of molten iron of the elements phosphorus pig iron to maintain a good indicator.2. Phosphorus pig iron and phosphorus hoop ratio is too low carbon content in molten iron can be added dedicated Recarburizer, to improve the content of carbon, sulfur content is out of range, add special desulfurizer, the sulfur control in the specified range. By adding the amount of pig iron, carbon, sulfur content.3. Phosphorus pig iron and phosphorus hoop ratio of melting is inevitable impurities is too large, can be dedicated Cleaner to remove impurities, improve casting quality, qualified rate. |
