After introducing 56Nb steel, in order to meet performance requirement of 56Nb steel fish plate on the railroad rail, the production technique of 56Nb steel fish plate has been adopted under the factory equipment conditions: 450 kg steel ingot is prepared by melting in 8 t arc furnace and casting at 1 570-1 580℃ which is heated to 1 250-1 270 ℃, trimmed to 185 mm×195 mm bloom after rolling by 600 series 2-stand rolling mill; then rolled 15 times by 600 series 2-stand rolling mill when steel ing

介绍了56Nb钢后，根据铁道接头夹板的性能要求并结合厂方的设备状况制定了56Nb钢鱼尾板材料的生产工艺：用8 t电弧炉冶炼，于1 570～1 580℃下铸成450 kg钢锭；将钢锭加热到1 250～1 270℃，经600系列2机架轧机5道次轧制后修整成185 mm×195 mm方坯；再将钢坯加热到1 050～1 150℃，由600系列轧机（2机架）共15道次轧制，用350系列（3机架）精轧机经3道次精轧成60 kg/m的鱼尾板材料，终轧温度约900℃。

Coke properties has been studied by high temperature SiC oven、infrared gas analyzer and X-ray diffraction. First set forward the relationship between UPC and coke reactivity, strength, fine coke and coke graphitization, and creatively find the graphitization degree of coke tends to 100% when temp. reaches to 1350℃ UPC is profitableness to coke properties;②The effect of UPC on liquid slag distribution and flow functions in experiment oven has been studied by mathematics simulation The effect of UPC on taking shape and dropping of high titanium-bearing B. F. slag has been studied by using high temp. oven simulation cohesive zone and dropping zone of blast furnace.

为了弄清楚这部分UPC对高炉冶炼钒钛磁铁矿过程的影响，①在实验室利用高温SiC炉、红外线气体分析仪、X—射线衍射仪等进行了一系列UPC对焦炭性能及石墨化度的影响研究，提出了UPC与焦炭反应性、抗压强度、粉化性能及焦炭石墨化度之间的关系，创造性的发现高炉内1350℃以上，焦炭的石墨化度已达100％，UPC对焦炭性能的影响有益而无一害；②采用数学模拟方式研究了UPC对实验炉内液态渣分布及流函数的影响，并利用高温熔滴炉模拟高炉软熔带、滴落带研究UPC对高钛渣滴落性能的影响，采用旋转式粘度计测定滴落渣性能并通过高倍矿相显微镜观察了滴落渣的矿物结构。

Produce the BF gas mud 100, OOOt every year. The raw mineral of puddling is the magnetite containing vanadium and titanium. The grade of iron is only 53%. The grade of sinter mineral is only 47-48%. So the percentage composition of iron is relatively low, only 29.70%. The grade of zinc is relatively high, reach 9.92%. And the percentage composition of carbon is relatively high, reach 16. 80%. In the next place, the BF gas mud is the production through sinter in high temperature.

攀钢炼铁的原矿物为钒钛磁铁矿，铁品位仅为53％，烧结矿品位为47％～48％，所以攀钢高炉瓦斯泥的铁品位也相对较低，仅为29.70％，并且含锌量高，达到了9.92％，含碳则高达16.80％；其次高炉瓦斯泥是高炉冶炼过程中的产物，SiO_2、Al_2O_3和铁部分熔融在一起，选矿难度增加。
