Title: Brick structure of degassing equipment
Inventor: ASO TADASHI
IPC: C21C7/10
Filed: 1996-06-10
Abstract: PROBLEM TO BE SOLVED: To reduce erosion speed of bricks in a circulating flow tube by dividing a brick at uppermost step into an upper and the lower parts at the uppermost part of the circulating flow tube in at least the center side of a vessel and inclining downward the boundary surface of both brick parts to molten steel flowing passage side. SOLUTION: The lower vessel 1 has cylindrical circulating flow tubes 3, 4. The circulating flow tube 3 lines the bricks at three or four steps, and each boundary surface between brick 5a at the uppermost step and a brick 5b just below the brick at the uppermost step has the inclination so that the friction force becomes large because the boundary area becomes larger than a horizatal boundary area. Direction of the inclination is formed as downward to the molten steel flowing passage side. The reason for dividing the brick at the uppermost step into two parts, is that the division into small parts is more profitable to restrain the crack caused by structural spalling, etc., progressed from the apparatus. The eroding speed of the brick at the uppermost step is reduced and the service life of the lower vessel 1 is improved.

Abstract: PROBLEM TO BE SOLVED: To enable application for rehabilitation by a method wherein stepping forces of pedals are detected to be compared with target values, when the forces are above the target values, the driving force of a motor is increased and when the forces are below the values, the driving force of the motor is decreased. SOLUTION: When pedals 15 are stepped in to drive an electric vehicle, the stepping forces are detected by a load cell 20 as pressure sensor means and a stepping force signal (a) is inputted into a control means 11. A control section 40 of the control means 11 performs a PID control and outputs a drive signal (b) to control the driving force of the motor 10. In other words, set values (f) of the stepping forces of right and left pedals are read out to be compared with the detected stepping force signal (a) and a difference Mn is calculated at each passage of specified time. A target value Kn is calculated based on the difference Mn to determine a driving force command value of the driving motor 10.  When the detected stepping force is larger than the set value (f) of the stepping force, the driving force is increased and when it is smaller than the set value, the driving force is decreased. As the result thereof changes in the stepping force of the pedals are eliminated, thereby enabling controlling of burden on feet and a waist.
