Title: Production of high-chromium alloy steel
Inventor: YOSHIDA MASASHI
IPC: C21C5/30
Filed: 1985-11-02
Abstract: PURPOSE:To make more efficient blowing by specifying the timing for blowing out in the stage of controlling the flow rate of a bottom blowing gas and oxygen blowing rate from the upper part and quantitatively determining the cross relation between the latter and the transition of the concn. of Cr and C then executing the blowing in a top and bottom blown refining furnace. CONSTITUTION:A steel bath of 1,600-1,800 deg.C is subjected to blowing at the flow rate of the bottom blowing gas controlled to >=0.06Nm<3>/min per ton of the molten steel and at the oxygen blowing rate from the upper part controlled to <=3.5 Ko2 (Nm<3>/min/ton of the molten steel) in the stage of producing a high Cr alloy steel by a top and bottom blown refining method. The blowing is so executed that the value of RIDAS expressed by the equation I attains 15-40. In the equation, [%Cr], [%C] are respectively the concn. (wt%) of Cr and C in the steel bath and Ko2 is the oxygen blowing rate from the upper part (Nm<3>/min/ton of the molten steel). The blowing is ended when the concn. [C] of C in the steel bath attains the [Cs] value defined by the equation II. In the equation, alpha is the constant determined by the intended oxidation ratio of Cr. The method is thereby made applicable to various blowing methods to permit the selection of RIDAS to an optional value among 15-40 and the adequate timing for blowing out is assured.

Filed: 1986-10-15
Abstract: PURPOSE:To shorten the test time of a cell in a partial cell with no access while decreasing the addresses by setting a PROM write data signal to a counter with a control signal. CONSTITUTION:In a data write mode a PROM array 1 is set under a write inhibiting state when a control circuit 2 is kept at level '1' for example. In this case, the value of a data signal 6 is set to a counter 4 when a control signal 7 is set at '1'. Then the value of the signal 6 is held by the counter 4 when the signal 7 is set at '0'. At the same time, the value set to the counter 4 is delivered to an address signal 5. Then the value stored in the relevant address is added to the signal 6 and the signal 2 is set at level '0'. Thus the array 1 is set under a write enable state and the signal 6 is stored in the array 1.
