Title: Control of extrusion of coke
Inventor: KAWATE OSAMU
IPC: C10B41/02
Filed: 1995-04-26
Abstract: PURPOSE: To suitably control the driving of an extruder by suitably setting the secondary resistance value of a coil type induction motor in response to the extrusion state of the extruder. CONSTITUTION: The secondary resistance value of a coil type induction motor for driving an extruder is set to the 1st notch to prevent the generation of a high starting electric current, and when a contact member is brought into contact with coke, the secondary resistance value is set to the 2nd or 3rd notch to reduce the collision of the contact member on the contact treatment and prevent the increase in the load between the coke and the side wall of a carbonization chamber. Until the coke is compressed with the contact member into a coke cake and subsequently moved at a constant speed, the secondary resistance value is set to the 5th notch to generate a high extrusion force. When the coke cake is moved at the constant speed, the secondary resistance value is set to the 6th notch to move the coke cake at a high speed.

Astigmatic aberration is also given to the other light beam through a condenser lens 40 and a cylindrical lens 41 and received by a quadripartite photodetector 42. Since the focal distance of the lens 41 is longer than the focal distance of the lens 38, the astigmatic aberration of the light beam through the lens 41 is larger than the astigmatic aberration of the light beam through true lens 38 and, consequently, the detection sensitivity of a focusing error signal FEa obtained from the detector 39 becomes larger than the detection sensitivity of a focusing error signal FEb obtained from the detector 42.
