Title: Method for decreasing seizure flaws of hot rolled material
Inventor: NAKANISHI TETSUYA
IPC: B21B45/02
Filed: 1992-11-26
Abstract: PURPOSE:To prevent the generation of the seizure flaws of a material to be rolled by applying and sticking a powdery noncombustible solid lubricant which is the principle material of the lubricant to the surface of the material to be rolled by using a liquid lubricant for which water glass is used as a binder, then reheating the surface of the material to be rolled to a temp. above the m. p. of the water glass. CONSTITUTION:The lubricant is prepd. by mixing the water glass with the principle material of the powdery solid lubricant consisting of metal oxides, such as alumina and silica, and inorg. compds., such as mica, to a liquid form. The water glass in the lubricant softens and melts of itself and improves the wettability with the material to be rolled when such lubricant is applied on the surface of the material to be rolled and its surface is reheated to the temp. above the m. p. of the water glass. The adhesion of the lubricant to the surface of the material to be rolled is thus stabilized. Then, the lubricant is securely stuck to the surface of the material to be rolled regardless of the material temp. at the time of the application, by which the generation of the seizure flaws on the material to be rolled is surely suppressed.
