Title: Method for treating dephosphorization of molten iron
Inventor: NAKAMURA KOICHI
IPC: C21C1/02
Filed: 1988-02-24
Abstract: PURPOSE:To efficiently execute dephosphorizing reaction in molten iron by specifying CaO/O values in refining agent at desiliconizing reaction stage preceding dephosphorization, the dephosphorizing reaction stage following this and the dephosphorizing reaction last stage at the time of dephosphorizing by blowing basic slag making agent and oxidizing agent into molten iron with carrier gas. CONSTITUTION:Before supplying the molten iron tapped from a blast furnace into a steelmaking furnace, dephosphorizing pre-refining is executed. Then, lime series basic flux and dephosphorizing agent composing of oxidizing agent are blown with the carrier gas. In this case, the refining reaction is divided into a first stage, which desiliconizing reaction precedes the dephosphorizing reaction till coming down to about 0.05% Si content in the molten iron, a second stage, which vigorous dephosphorizing reaction develops as following the above stage, and a third stage, which P in the molten iron is decreased in accordance with progress of the dephosphorizing reaction and the dephosphorizing reaction is delayed. By making 2.3-3.0 of the value of CaO/O in the dephosphorizing agent used in the first stage and 1.7-2.2 of the value of CaO/O in the dephosphorizing agent in the second and third stages, O2 efficiency used in the dephosphorizing reaction is improved, and pre-dephosphorizing reaction in the molten iron is executed at extremely efficiently.

Filed: 1984-03-05
Abstract: PURPOSE:To improve the range finding accuracy of the TDMA system by adding a BTR synchronizing signal to a short burst signal only to quicken a rise time of range finding information. CONSTITUTION:When a receiver 11 of a slave station receives a short burst signal being a slave station signal in a frequency f2, the receiver 11 regenerates a clock from a BTR and detects an UW of the slave station. A receiver 10 of a base station signal receives a base station signal in a frequency f1 and detects a referenced RUW by using the clock signal. A frequency multiplier 14 obtains a difference of the detection timing between the UW and RUW by using the clock having a frequency of n-times and the result is transmitted to the slave station as the range finding information S via a selector 19. The steady-state processing is started by allowing the slave station to transmit the full burst signal toward a communication satellite based on the signal S.
