Title: Production of rigid water-crushed granulated slag
Inventor: IDE HIDEO
IPC: C04B5/06
Filed: 1997-11-21
Abstract: PROBLEM TO BE SOLVED: To inexpensively produce a rigid water-crushed granulated slag suitable for a fine aggregate for concrete and mortar by a current water-crushing device in front of a furnace. SOLUTION: At the time of water-crushing a molten blast furnace slag, the water-crushing is executed by using a water in which 100-1,000 ppm water- soluble polymer is dissolved as a cooling water for water-crushing. As the water-soluble polymer, for example, more than one kind carboxymethyl cellulose and polyethylene oxide are used. When the molten blast furnace slag is brought into contact with the water, if the water-soluble polymer is dissolved in the cooling water, cooling speed is raised and a growth of a coagulating layer becomes fast. Therefore, a foaming reaction causing specific gravity drop is hardly caused and the slag is densified. The rigid water-crushed granulated slag can be inexpensively produced with the current water-crushing device in front of the furnace without executing a new plant investment.  The blast furnace granulated slag is used for not only blast furnace cement but also for fine aggregate, so it contributes for changing the blast furnace slag into resources.

Title: Nozzle drive control device in nozzle movable type burner
Inventor: TAKAHASHI KIYOSHI
IPC: F23N1/00
Filed: 1991-11-26
Abstract: PURPOSE:To protect the coils of a stepping motor from burning by extending calculation time up to the next proper combustion volume when the difference between the previous proper combustion volume and the current proper combustion volume is small. CONSTITUTION:A proper combustion volume difference arithmetic operation means 22 calculates the difference between the current proper combustion volume calculated by a proper combustion volume arithmetic operation means 18 and the previous proper combustion volume stored in a storage device. When the difference is small between the current combustion volume and the previous proper combustion volume, the calculation time up to the next proper combustion volume is extended. Therefore, when the change in the proper combustion volume is small, the calculation cycle of proper combustion volume is extended. As a result, the drive time ratio to the stop time of a stepping motor is minimized, which makes it possible to protect the coils of the stepping motor from burning by excessive heating.
