3FeNb在钢液中的溶化行为及在钢包精炼过程中提高Nb收得率的最佳工艺显示文摘阐述了标准铌铁(FeNb)的微观组织特性及其溶入钢液中的研究结果。在实验室的感应炉中进行了不同温度下的非连续试验,分析了固相FeNb与钢液凝固层界面的微观组织,并与原始FeNb粒子的微观组织进行了对比。这些试验研究结果可以阐释FeNb的溶解机制和它在不同炼钢温度下的融入动力学条件。标准FeNb在钢水中溶解的试验结果证实FeNb颗粒的溶解速率高于有关文献中报告的结果,它们认为FeNb粒子的熔化温度高(>1600℃),所以在其模型中假定FeNb的溶解仅是通过固相粒子的扩散实现。本项工作得到的试验证据为标准FeNb的溶解机理提供了一种新的说法:在1500~1510℃受其共晶区的熔化行为控制,在1530~1575℃温度范围内则由初始板条相的熔化行为所主导,也就是说,均低于1600℃左右的炼钢温度。根据这些研究结果和炼钢厂已有的生产经验,对于微合金化钢在二次精炼阶段加入FeNb推荐了最优的工艺。Edmundo Burgos Cruz Daniel Pallos Fridman Marcelo C Carboni Rogério Contato Guimares Marcos A Stuart Nogueira Ferdinando Luiz Cavallante 王厚昕 2010世界钢铁2010,,6:2

15Niobium in Microalloyed Steels Unchallenged for Its Main Applications显示文摘During the past five decades niobium has emerged as the most important microalloying element in high strength steels.The first theories to explain its role were presented in the seminal publications of Woodhead,Morrison and Gray.Today niobium microalloyed steels are unchallenged for their main applications.Some examples include linepipe for gas transportation,automotive steels used in body-in-white and structural parts,shipbuilding,steel towers and steel structures in civil construction that exhibit better fire resistance and seismic load performance.Modern technology for steelmaking helped emphasize the superior overall properties that can be attained with the use of niobium.Gas linepipe is the best example of cleaner steel with carbon levels below 0.05% manufactured economically.Modern niobium microalloyed steels present the optimal balance of strength,toughness,weldability and formability.This paper describes the evolution of the technology associated with niobium in microalloyed steels,technology that secured its status as the efficient solution to solving today's challenges:safety,energy efficiency and environmental concerns.The paper also presents evidence that enhances the case that there is a secure,stable,long-term supply of the ferroniobium used to manufacture these steels.Nogueira Marcos A Stuart Carneiro Tadeu 2011Journal of Iron and Steel Research(International)2011,18,S1:0
16Development of microalloyed steels for high temperature carburizing显示文摘The potential for use of microalloy additions to suppress abnormal austenite grain growth and produce steels with enhanced bending fatigue resistance after high temperature vacuum carburizing was investigated in a series of Ti-modified SAE 8620 steels with w(niobium) additions up to 0.1%.Results are considered from a series of papers at the Advanced Steel Processing and Products Research Center on the effects of Nb content,heating rate, rolling history,and processing temperature on the evolution of austenite grain structures in carburizing steels. Emphasis is placed on understanding the effects of alloying and processing on each stage in the annealing process including the as received laboratory rolled conditions,during the onset of carburizing after annealing at different heating rates,and after annealing for various times at carburizing temperatures up to 1 100℃.Heating rate to the carburizing temperature was shown to be an influential variable and suppression of abnormal grain growth was dependent on the development of a critical distribution of fine NbC precipitates,stable at the austenitizing temperature.The importance to industrial carburizing practice of heating rate effects on precipitates and austenite grain size evolution are discussed and correlated to selected data on fatigue performance.David K MATLOCK John G SPEER Steven G JANSTO Marcos STUART 2010Baosteel Technical Research2010,4,S1:0
17The outcomes and safety of patients undergoing endoscopic retrograde cholangiopancreatography combining a single-use cholangioscope and a single-use duodenoscope:A multicenter retrospective international study显示文摘Background: Duodenoscope-related multidrug-resistant organism(MDRO) infections raise concerns. Disposable duodenoscopes have been recently introduced in the market and approved by regulatory agencies with the aim to reduce the risk of endoscopic retrograde cholangiopancreatography(ERCP) associated infections. The aim of this study was to evaluate the outcome of procedures performed with single-use duodenoscopes in patients with clinical indications to single-operator cholangiopancreatoscopy. Methods: This is a multicenter international, retrospective study combining all patients who underwent complex biliopancreatic interventions using the combination of a single-use duodenoscope and a single-use cholangioscope. The primary outcome was technical success defined as ERCP completion for the intended clinical indication. Secondary outcomes were procedural duration, rate of cross-over to reusable duodenoscope, operator-reported satisfaction score(1 to 10) on performance rating of the single-use duodenoscope, and adverse event(AE) rate. Results: A total of 66 patients(26, 39.4% female) were included in the study. ERCP was categorized according to ASGE ERCP grading system as 47(71.2%) grade 3 and 19(28.8%) grade 4. The technical success rate was 98.5%(65/66). Procedural duration was 64(interquartile range 15-189) min, cross-over rate to reusable duodenoscope was 1/66(1.5%). The satisfaction score of the single-use duodenoscope classified by the operators was 8.6 ± 1.3 points. Four patients(6.1%) experienced AEs not directly related to the single-use duodenoscope, namely 2 post-ERCP pancreatitis(PEP), 1 cholangitis and 1 bleeding.Conclusions: Single-use duodenoscope is effective, reliable and safe even in technically challenging procedures with a non-inferiority to reusable duodenoscope, making these devices a viable alternative to standard reusable equipment.Alessandro Fugazza Matteo Colombo Michel Kahaleh V.Raman Muthusamy Bick Benjamin Wim Laleman Carmelo Barbera Carlo Fabbri Jose Nieto Abed Al-Lehibi Mohan Ramchandani Amy Tyberg Haroon Shahid Avik Sarkar Dean Ehrlich Stuart Shermand Cecilia Binda Marco Spadaccini Andrea Iannone Kareem Khalaf Nageshwar Reddy Andrea Anderloni Alessandro Repici 2024Hepatobiliary & Pancreatic Diseases International2024,23,1:0
18不确定性量化及典型反问题:二氧化碳的捕获及存贮显示文摘反问题求解中不确定性量化的问题在数学科学中是一个令人兴奋的研究领域,在分析,计算,概率论和统计学的交汇领域中提出了意义重大的挑战.就来自诸如天气预报,流行病学以及交通流等物理学,生物学和社会科学中的的各种不同的问题而言,不确定性量化的可应用范围是极其巨大的.粗略地说,反问题要面对的是带有数据的数学模型,因此我们可以推演出为运行此类模型所需要的输入;然后可将有关这些输入的知识用于做预测,甚至设计基于此等预测的控制策略.模型和数据二者通常都是不确定的,作为结果的推演和预测也都是不确定的;因此,如果不确定性得到量化,那么基于此等预测作出的任何决策或控制策略将会得到极大的改善。Marco Iglesias Andrew M.

19Dissolution of FeNb in liquid steel and best practices to increase niobium recovery during ladle refining显示文摘This paper presents a microstructural characterization of standard ferroniobium(FeNb) and a study of its dissolution in steel.Interrupted dissolution trials at different temperatures were carried out in a laboratory induction furnace.The microstructure at the interface between solid FeNb and frozen steel was analyzed and compared with the original FeNb particles.The results allowed clarifying both the FeNb dissolution mechanism and its incorporation kinetics at steelmaking temperatures.Experimental results from the dissolution of standard FeNb in liquid steel proved that the dissolution rates of FeNb particles were higher than those reported in the pertinent literature,where models assume that FeNb dissolves only by the diffusion of solid particles due to its high melting temperatures(over 1 600℃).Most recent FeNb phase diagrams and DTA analyses have shown that standard FeNb begins to melt down below 1 600℃.The experimental evidences in this work have led to the adoption of a new description of the dissolution mechanism whereby standard FeNb dissolves predominantly by the melting of its eutectic zones at 1500℃to 1510℃and,later on,by the melting of the primary laths between 1530℃and 1575℃,i.e.,below the steelmaking temperatures of around 1 600℃.Based on these results and on previous melting-shop experience,this paper recommends the best practices for the addition of FeNb during the microalloyed steels secondary refining phase.Edmundo Burgos CRUZ Daniel Pallos FRIDMAN Marcelo C CARBONI Rogerio Contato GUIMARAES Marcos A Stuart NOGUEIRA Ferdinando Luiz CAVALLANTE 2010Baosteel Technical Research2010,4,S1:0
