Title: Method for control of flow rate in converter waste gas treatment device
Inventor: FUKUSHIMA SHIYUN
IPC: C21C5/38
Filed: 1980-05-12
Abstract: PURPOSE:To control the flow rate of waste gas easily and highly efficiently with high accuracy by obtaining the flow rate of the gas produced in a converter by subtracting an estimated suction flow rate of the furnace port from the waste gas flow rate of the current point and adding a suitable preset suction flow rate of the furnace port. CONSTITUTION:At the start of blowing, first the reference coefficient of pressure loss at skirt height is determined with the waste gas flow rate from a waste gas flowmeter 3, and the signal of the furnace port hood pressure from a pressure gate 4, by an arithmetic device 7. Thence, ignition is made and the information on the flow rate from the flowmeter 3, the analysis value from an analyzer 5, the hood pressure from the gage 4 and skirt height is accumulated in the device 7 at every fixed period. After the ignition, the correction coefficient for the delay time of the analyzer 5 is calculated, by which the suction flow rate of the furnace port is determined and the waste gas flow rate is calculated. The waste gas flow rate is applied as a set value to a PID. In the PID, operations are made, and a manipulated variable signal is applied to a damper DC6 for controlling flow rate, whereby the waste gas flow rate is controlled. Thereafter, this is repeated at every fixed period.

Abstract: PURPOSE: To surely press-weld the microporosity of the cast billet, by reheating the continuously cast billet to specified temperatures after casting or after reducing thickness, without permitting to pass the transformation point, and by applying the hot rolling work with the specified shape ratio, and by restricting the hydrogen inclusion of the steel.  
     CONSTITUTION: The spread of the microporosity of the cast billet's core portion due to the hydrogen inclusion of the steel, is prevented by the heat treatment. After the continuously cast billet is cast or is reduced in its thickness, the billet is reheated to Ac 3  or moreW1170°C or bellow without permitting the billet to pass the transformation point. While above thickness reducing work or the hot rolling work for the thick steel plate, the shape ratio α is maintained at a value obtained from the formula I at least one time. The 18mm or more thick steel plate is manufactured by restricting the hydrogen inclusion Hc (ppm) of steel at the middle zone of thickness to a value obtained from the formula II. Besides, hereupon, the casting structure at the continuously cast billet's core portion is made the regular system, and the shape ratio α obtained from the formula III can substitute the value obtained from the formula I.
