TWO-PACK-TYPE SEIZING INHIBITOR FOR HOT PLASTIC WORKING AND PROCESS FOR PRODUCING SEAMLESS TUBE WITH THE SAME

Title:

TWO-PACK-TYPE SEIZING INHIBITOR FOR HOT PLASTIC WORKING AND PROCESS FOR PRODUCING SEAMLESS TUBE WITH THE SAME

Document Type and Number:

WIPO Patent Application WO/2006/085599

Kind Code:

A1

Abstract:

A seizing inhibitor for hot plastic working which is a two-pack type inhibitor consisting of: a first aqueous solution containing sodium silicate in an amount of 10-30 mass% in terms of anhydride amount based on the whole first aqueous solution; and a second aqueous solution containing one or more members selected from the group consisting of organic acids and water-soluble amine salts thereof, inorganic acids and water-soluble amine salts thereof, water-soluble amines, water-soluble alcohols, and water-soluble metal chlorides. The seizing inhibitor, after having been supplied by application to a disk roll type guide shoe, is held on the periphery of the disk roll type guide shoe without being washed off by cooling water for the rolls. Consequently, the seizing inhibitor does not adhere to the rolls, whereby a tube material can be perforated/rolled without slipping on the rolls.
