  fettling
Intelligent robotic fettling using a visual feedback technique and force sensing
      
In this paper, we present the results and implications of our experimental study into robotic fettling operation using a visual feedback technique and force sensing.
      
A real time supervisory control over the robotic fettling operation is proposed using force data.
      
A theoretical model verified with experimental results is established to describe and to optimise the empirical relationship among the process parameters of the fettling process.
      
The empirical relationship derived enables the robotic fettling system to react and to compensate accordingly for variations in the burr profile thus producing a fettling result with better consistency and accuracy.

The life of lining of 30 t. top-blown converter № 2 in the steel plant has reached to 2868 heat on May 14,1978. The campaign lasts 59 days and 17 hours 26 min. and the average output per heat is 34.68 t., In this campaign the converter lining consists of pitch-dipped synthetic magnesia-dolomite bricks in main parts together with lightly burnt pitch-dipped bricks made of synthetic materials and dolomite, During the campaign, the quality of hot metal is good. Some measures have been taken in respect to raw materials, their feeding, oxygen supply,slag formation and temperature control in order to relieve erosion of the lining. The lining has been proved to have good resistance to erosion. After 526 heats, fettling has been started on the feeding side. After 2073 heats the permanent layer of lining has been exposed in some places. By means of spraying wet fettling materials life of converter lining was further prolonged another 800 heats. Consumption of refractory materials was 3.19 kg/t. of steel This campaign gave satisfactory parameters in output, steel quality, consumption of refractory materials and life of lining.

首钢炼钢厂2号30吨氧气顶吹转炉炉令于1978年5月14日达到2868炉.炉役共历时59天17小时26分钟,平均每炉产钢34.68吨.这个炉役在炉衬的主要部位首次大量使用合成镁白云石烧成油浸砖,配合用合成料、白云石料的轻烧油浸沥青结合砖进行综合砌炉.炉役过程中,铁水条件良好,并在原料、装入、供氧、造渣和温度制度方面采取措施,减缓对炉衬的浸蚀:整个炉衬显示良好的抗浸蚀性能,526炉开始于装料侧补炉,2073炉时炉衬局部见永久层后,以湿法喷补手段使炉龄延长800炉,炉衬耐火材料消耗3.19公斤/吨钢.这个炉役显示了"高产、优质、低耗、长寿"的良好效果.

An aspect is summarized of microscopic studies on certain slagged high-alumina bricks dismantled after arc furnace roof service with various steel smelt-ing operations in the past years since 1957. The bricks were attacked mainly byMgO, CaO and iron oxides. The MgO had its sources by evaporation and infiltra-tion from either magnesite fettling material or basic furnace wall under highertemperatures.

An aspect is summarized of microscopic studies on certain slagged high-alumina bricks dismantled after arc furnace roof service with various steel smelt-ing operations in the past years since 1957. The bricks were attacked mainly byMgO, CaO and iron oxides. The MgO had its sources by evaporation and infiltra-tion from either magnesite fettling material or basic furnace wall under highertemperatures. It was identified by X-ray powder pattern and by microscopic ob-servation that the periclase grains or/and needles occur in the slagged zone ofbricks. The iron oxides, if presence, accumulated themself mostly on the surfacelayer of slagged zone, formed an assemblage of reaction products and convertedinto two systems of ferro-spinels as (MF')A and (F'M)F. However, only MAspinel was formed with less iron oxides content. Other equilibrium phases contain-ing CaO may be monticellite and anorthite. The reaction products observed seemto be calcium- hexaluminate and gehlenite in the inner layer of slagged zone,and a certain amount of glass is also present.

本文汇集1957年以来某些电炉炉顶使用后高铝砖的显微镜观察工作,砖体主要受MgO,CaO和铁氧化物侵蚀.MgO来源于补炉镁砂和镁质炉墙在高温下的冲蚀和挥发,X射线和显微镜分析证实渣蚀带一些区域内存在粒状和针状方镁石晶体.存在铁氧化物时,基本上吸附在渣蚀带表面,形成有两个尖晶石固溶体〔(MF’)A和(F’M)F〕系列的矿物共生组合,当不存在铁氧化物时,在渣蚀带生成纯MA.其它平衡相有钙镁橄榄石和钙长石.在渣蚀带内层,反应产物为六铝酸钙和钙铝黄长石.

This paper describes the protection mechanism of blast furnace hearth lining with materi-als containing titanium based on laboratory test simulating errosion of the lining and examin-ation of the samples taken after the blown-out of №2 blast furnace. The protection functionof the materials is an automatically selective fettling course. Furthermore, due to the addition of Ti-bearing materials. mineral constituent of slag andslag/brick interface varies considerably, a series of minerals of high melting point may formand they may do some good for the protection of the hearth lining.

本文叙述了湘钢2号高炉停炉取样及实验室的炉缸侵蚀模拟试验,分析了含钛物料的护炉机理,是“一种能自动选择的补炉过程”。此外,高炉配加含钛物料冶炼后,炉渣的矿物组成以及渣-砖界面的矿物组成发生很大变化,形成一系列高熔点矿物,有助于保护炉缸。
