  • Brittle formed product and iron-based power material and method for manufacturing these materials
    Patent number: 7135053
    Abstract: Cotton-like aggregates (B) including grinding chips from an iron-based metal and a grinding fluid containing oil and water are compression molded for forming a brittle compact (C) having the fibrous grinding chips roughly sheared and excessive water and oil removed therefrom. The brittle compact (C) is crushed for further finely shearing the grinding chips and the resultant grinding chips are mixed with a solidification assistant (D) for producing an iron-based powder material (E) containing the solidification assistant (D).
    Type: Grant
    Filed: October 1, 2001
    Date of Patent: November 14, 2006
    Assignee: Koyo Seiko Co., Ltd.

  • Briquette as material for steel making and method for production thereof
    Publication number: 20020152843
    Abstract: Cotton-like aggregates (B) containing grinding chips from an iron-based metal and a grinding fluid containing oil and water are compression molded thereby forming a brittle compact (C) in which the fibrous grinding chips are roughly sheared and which is removed of excessive water and oil. The brittle compact (C) is crushed for further finely shearing the grinding chips and then, the resultant grinding chips are mixed with a solidification assistant (D) for obtaining powder (E) containing the solidification assistant (D). The powder (E) is solidified by compression molding, thereby forming a water-containing briquette (F). A briquette (A) for use as steelmaking material, which contains powdery pure iron and oil, is obtained by removing the water from the water-containing briquette (F). Without crushing the brittle compact (C), it is also possible to form the briquette (A) for use as steelmaking material by impregnating the brittle compact (C) with the solidification assistant (D) and then drying th compact.
