Title:
A METHOD FOR MAKING RING FORGING COMPONENT
Document Type and Number:
WIPO Patent Application WO/2008/095446
Kind Code:
A1
Abstract:
A method for making ring forging component. Keep the molten steel whose temperature
is between 1570 centigrade and 1700 centigrade in the heat preservation furnace
whose inner temperate is 1540 to 1600 centigrade to keep the heat. Weigh them by
the small casting bag with fixed weight and inject them into the eccentric molding
module after fixing their weights; deprive the module under the temperature
between 1150 and 1250 centigrade; get rid of the burr; and forge them to the needed
size under the temperature between 1100 and 1200 centigrade; and ring roll them
to the size of forging component under the temperature of 950 to 1050 centigrade;
at last , get rid of the burr occurred when ring rolling ; then the ring forging component
is made. The method takes use of the spare heat of molten steel, casting, forging,
rolling and quenching; it complements the whole product process by using the
decreasing stair of the temperature of molten steel; it saves the power and reduces
the cost; it reduces the environmental pollution and the let of exhaust gas; it
shortens the product period and increases the productivity; it reduces the product
cost and increase the economic benefit.
