摘要： PURPOSE:To produce a satisfactory dephosphorizing effect when a high carbon steel is refined by blowing in a top and bottom blowing converter, by using a specified slag forming agent. CONSTITUTION:When a high carbon steel is refined by blowing in a top and bottom blowing converter, cement clinker or slag formed in an electric arc furnace in a reduction stage is substituted for part of lime. Thus, a high-carbon low-phosphorus steel can be manufactured by top and bottom blowing independently of the flow rate of oxygen to be fed, the kind of gas to be blown from the bottom, the flow rate of the gas, the basicity of slag, the molten iron ratio, etc.

摘要： PURPOSE:To pretreat molten iron efficiently and simply by adding a specified amount of CaCO3 to scale or the like to obtain a molten iron desiliconizing agent having a specified grain size and by adding the agent to the molten iron during passing through an iron discharging spout. CONSTITUTION:At least 8-21wt% CaCO3 is added to an iron oxide-base material such as scale, ore or minus mesh from a sintering stage to obtain a molten iron desiliconizing agent composed of grains. All the grains have =50wt% of all the grains. Molten iron discharged from a blast furnace is desiliconized with the desiliconizing agent during passing through an iron discharging spout. Since slag formed by the desiliconization has high flowability, it can be removed easily through a slag discharging spout placed at the downstream side of the iron discharging spout.

摘要： PURPOSE:To prevent central segregaion of a continuous casting billet at the joint part and to improve the yield thereof by providing respectively electromagnetic stirrers near the water-cooled casting mold of a continuous casting device, the terminal part of solidification of the drawn billet and between said parts and operating the stirrers in accordance with a schedule. CONSTITUTION:A billet is drawn while all of the 1st-3rd electromagnetic stirrers 2a, 2b, 2c are operated during the time when the joint part of different kinds of steels moves by the length corresponding to the distance L (b-c) from the molten metal surface in a casting mold 1 to the 2nd stirrer 2b and to the 3rd stirrer 2c. The billet is drawn by stopping the 3rd stirrer 2c and operating the 1st and 2nd stirrers 2a, 2b during the time when the joint part of the different kinds of steels drawn by the length corresponding to the distance L (b-c) arrives at the 2nd stirrer 2b. The billet is drawn by operating only the 1st stirrer 2a during the time when said joint part moves to the 2nd-3rd stirrers 2b, 2c. The billet is drawn under stirring by the stirrers 2c, 2a after the joint part arrives at the stirrer 2c.
摘要翻译：目的：为了防止在连接部分连续铸造坯料的中心分离并通过在连续铸造装置的水冷铸造模具附近设置分别电磁搅拌器来提高其产量，拉伸坯料的凝固终端部分和表示部件按照时间表操作搅拌器。构成：当在不同种类的钢的接合部分移动相当于距离熔融金属的距离L（bc）的长度的时间期间，所有第1〜3电磁搅拌器2a，2b，2c全部被操作时，在第1搅拌机2b和第3搅拌机2c的铸模1中的表面。通过停止第三搅拌器2c并操作第一和第二搅拌器2a，2b，在对应于距离L（bc）的长度拉伸的不同种类的钢的接合部分到达第二搅拌器 2B。在所述接合部移动到第2〜第3搅拌器2b，2c的时间期间，只通过操作第1搅拌器2a来抽出坯料。在接头部分到达搅拌器2c之后，通过搅拌器2c，2a的搅拌下将钢坯拉伸。

摘要： PURPOSE:To promote the dispersion of disiliconizing agent into hot metal by the gravity energy at difference parts in level and to raise the desiliconizing oxygen efficiency, by providing not less than 2 difference parts in level on the downstream side of the position of pig-iron runner for injection of desiliconizing agent in carrying out the pig-iron runner desiliconization on the casting bed of blast furnace. CONSTITUTION:Not less than 2 difference parts in level are provided on the downstream side of the position A of pig-iron runner for injection of desiliconizing agent in carrying out the pig-iron runner desiliconization on the casting bed of blast furnace. For example, the head of drop weir 7 is lessened and at the same time the second drop weir 7a and the third drop weir 7b are further provided on its downstream side. In that case, because allowable head is limitted, their total head is the same as before. Thus, the mixing of hot metal and desiliconizing agent are promoted and the desiliconizing oxygen efficiency is raised.
摘要翻译：目的：通过不同部位的重力将促进脱硅剂分散到铁水中，提高脱硅效率，通过在生铁位置的下游侧提供不少于2个不同部位的水平用于在高炉铸造床上进行生铁转杯脱硅的脱硅剂注射器。构成：在高炉浇铸床上进行脱铁剂脱水处理的生铁流水线位置A的下游侧，不得少于2个不同部位。例如，下降堰7的头部被减小，同时第二堰坝7a和第三堰堰7b进一步设置在其下游侧。在这种情况下，因为允许的头部被限制，它们的头部与之前相同。因此，促进了热金属和脱硅剂的混合，提高了脱硅氧的效率。
