Title: Manufacture of urethane foam body
Inventor: SAKAMOTO SEISHICHI
IPC: B29C39/38
Filed: 1982-07-27
Abstract: PURPOSE:To expedite an increase in the strength of a skeleton, to shorten a time required until the removal from a die, and thereby to manufacture the title foam body with excellent productivity, by heating an urethane foam in an outer shell body after cooling the same for a prescribed time. CONSTITUTION:A molding die 6 consisting of a top force 7 and a bottom force 8 is heated to the temperature of 45+ or -5 deg.C by supplying hot water through a water pipe 10 of the die 6, and then foamable urethane resin is injected into the cavity 9 of the die 6 and foamed and inflated therein to form an urethane foam. About five seconds after a tack-free time passes, cold water of 10+ or -5 deg.C is supplied through the pipe 10 to cool down the foam, and thereby the internal pressure of the foam is lowered early (solid line A). Next, about ten-twenty seconds after a foaming time passes, hot water of 45+ or -5 deg.C is supplied to the pipe 10 to heat the molding die 6. Thereby curing reactions are expedited and thus the strength of the skeleton of the foam is increased early (solid line B).

Abstract: PURPOSE:To produce a high toughness steel having high toughness and low yield ratio without deteriorating weldability by subjecting a steel with specific composition to heating up to specific temp., to the rolling reduction at specific cumulative draft, and to the cooling at specific cooling velocity. CONSTITUTION:The steel has a composition consisting of, by weight, 0.01-0.20% C, <=1.0% Si, 0.6-2.0% Mn, 0.05-1.0% Mo, <=0.1% Sol.Al, and the balance Fe with inevitable impurities. The steel is heated up to a temp. in the region between 850-1050 deg.C and subjected to rolling reduction at least in a nonrecrystallized austenite region at >=30% cumulative draft. Subsequently, cooling is performed to <=550 deg.C at >=2 deg.C/sec cooling rate in the central part in a plate thickness direction. Further, the steel is subjected to primary heating at <=1250 deg.C to undergo rolling reduction. After cooling, the steel is heated, as secondary heating, up to 850-1050 deg.C to undergo rolling reduction. By this method, the steel can be applied to various fields in a wide range, such as steel material for line pipe and steel material for tank.
