Title: Descaling apparatus for hot rolled steel sheet
Inventor: INOUE TADAATSU
IPC: B21B45/06
Filed: 1980-01-09
Abstract: PURPOSE: To titled apparatus made possible to effectively descale, by arranging the brushing roll behind the differential rolling mill.  
     CONSTITUTION: In the said differential rolling mill 5, the upper roll 5- 1  and the lower roll 5- 2  are rotated at different circumferential speeds. Hence, a horizontal stress due to the tension is caused in the hot rolled steel sheet S passed through the gap of upper and lower roll 5- 1 , 5- 2 ; this horizontal stress causes cracks in the scale covering the steel sheet S. Moreover, when the hot rolled steel sheet S is wrapped around upper and lower rolls 5- 1 , 5- 2 , a bending stress is caused in the steel sheet S by the bending work, and hereby, the descaling effect is increased. The brushing roll 6, installed on the run-out side of above stated differential rolling mill 5, perfectly removes the scale crushed by the mill 5 from the surface of the hot rolled steel sheet S, by touching the surface of steel sheet S so as to grind it. As the material of the hair of the brushing roll 6, nylon, etc., including abrasive grains is employed.

Title: Operation of blowing pulverized coal in blast furnace
Inventor: YAMASHITA MICHIHIKO
IPC: C21B5/00
Filed: 1993-01-08
Abstract: PURPOSE:To stabilize the operation of a blast furnace by periodically varying blowing flow rate of pulverized coal blown from a tuyere in the blast furnace. CONSTITUTION:At the time of blowing the pulverized coal from the tuyere in the blast furnace, the blowing flow rate of the pulverized coal is periodically varied. By the variation, in the period when the pulverized coal is blown in a large quantity, the pulverized coal concn. in the raceway is increased and the oxygen becomes short and the combustion ratio of the pulverized coal is lowered. On the other hand, in the period when the blowing rate of the pulverized coal lowers, the pulverized coal concn. is lowered and the oxygen becomes the excess state and consumption of coke or coke powder is promoted. By this method, even if there is the variation in the operational condition of the blast furnace, the combustion ratio of the pulverized coal in the front of the tuyere according to this condition can optionally be controlled and the operation in the blast furnace can stably be maintained.
