Title: Plug for hot rolling of metal tube
Inventor: YOSHIHARA SEISHIROU
IPC: C10N40/24
Filed: 1978-01-27
Abstract: PURPOSE:To upgrade the quality of tube as well as reduce the amount of lubricant used by the procedure in which rolling plug and guide plug are connected by a coupling bar, and then a lubricant-housing room is provided between the space for lubricating uniformly the whole inner face of tube. CONSTITUTION:A hot expansible lubricant is filled in the lubricant-housing room 8. When high temperature tube surrounds the lubricant-housing room 8 at the time of rolling, the lubricant expands due to the radiant heat of the tube and flows out of the overflow hole to fill up the space between the inner face of tube, rolling plug, and guide plug and then as the tube moves, pulled into the aperture between the accompanying tube 1 and the rolling pulg 3, whereby uniform lubrication is produced throughout between the inner face of tube and the rolling plug. The expansion and flowing time of the lubricant varies with position and other conductions such as the material, thickness, and shape of the outer wall 7, the overlapping number of the outer wall, and the kinds and amounts of lubricants. Thus, by selecting proper ones of these conditions, the expansion of lubricant can be continued unitl the end of rolling and also uniform supply of lubricant can be attained.

Title: Operation of blast furnace
Inventor: FUJITA ISAO
IPC: C21B5/00
Filed: 1979-01-24
Abstract: PURPOSE:To carry out stabilizing operation at a low coke ratio by balancing three factors of an oxygen amt. charged per min. per unit volume of a blast furnace, a charging ratio of ore to coke and a rate of the reduction of the ore by a method wherein crushed ores or deformed pellets are used when the condition of the blast furnace is controlled by the three factors. CONSTITUTION:An oxygen amt. X charged per min. per unit volume of a blast furnace, a charging ratio Y of ore to coke and an average JIS reduction rate of the ore are determined as the factors of furnace heat balance variation, the operation being influenced by the factors. The three factors are composed of three parallel axes, and X, Y and Z valued are scaled. Lines l1 and l2 are drawn between the corresponding values to the factors X, Y and between the corresponding values to the factors Y, Z to form angles theta1, theta2 to the horizontal line. There is a furnace heat stabilizing zone where theta is from 150-210 deg.C when theta=theta1+theta2+180 deg.. In order to stabilize the furnace heat by decreasing the O2-charging value X, increasing the low coke ratio Y and setting theta within the above range, the ores are crushed or deformed pellets are used to increase Z value. By controlling theta within the desired range, the condition of the furnace can be stabilized.
