Title: Cooling method for steel material
Inventor: BANDOU SEIJI
IPC: C21D1/00
Filed: 1978-07-13
Abstract: PURPOSE: To stabilize the cooling at the low cooling capacity region which has been considered difficult according to the conventional method, and to prevent the deterioration of the quality, by injecting the mixture of water and steam from the injection nozzle, in case of the heat treatment for the steel material by water cooling.  
     CONSTITUTION: In case of the heat treatment for the steel material using the dual fluid (air and water) injection nozzle 10 of the conventional method, which is inapplicable because of its unstableness in the cooling capacity under the condition that the air pressure is lower than 0.5kg/cm 2 , the steam instead of air is introduced into the air supply chamber 14, and the water and steam are injected from the injection nozzle 18. Hereby, when the steel material is cooled to 800W 500°C, the time for cooling is 50 seconds by the conventional method, however, this method can extend the minimum cooling capacity so as to continue the cooling for about 80 seconds. As a result, the cooling at a low cooling capacity region, which is unstable by the conventional dual fluid nozzle, is stabilized.

Abstract: PROBLEM TO BE SOLVED: To enable a control board to immediately recognize an initial position of a car after current-carrying by arranging a door zone sensor to detect door zone vanes respectively arranged in cargo landing floor positions of respective stories and position vanes respectively and separately arranged from the door zone vanes of the respective stories, in the car. SOLUTION: Power failure is caused at elevator operating time, and when an electric current is carried thereafter, a command is sent out to a hoist 4 through an inverter 5 from a control board 6, and a car 1 is made to temporarily travel in the upward direction. Then, a door zone sensor 17 detects a door zone vane 12, and detects a positione vane 15 in the next place. A distance (t2 ) between the door zone vane 12 and the position vane 15 is detected by a rotary encoder 10, and this signal is outputted to the control board 6. Since this distance (t2 ) is different from distances (t1 and t3 ) of the other stories, the control board 6 can immediately recognize that on which story an initial position of the car 1 exists only by making the car travel a little after current- carrying.
