REINFORCED ROLL AND METHOD OF MAKING SAME

摘要

A method of making an article adapted for use as a wear resistant working surface of a roll includes positioning hard elements in predetermined positions on a bottom surface of a mold. The hard elements comprise a first end and an opposed second end. The second end of each hard element rests on the bottom surface, partially filling a void space and defining an unoccupied volume in the mold. Inorganic particles are added to the mold to at least partially fill the unoccupied volume and provide a remainder space. The hard elements and the inorganic particles are heated to an infiltrating temperature and infiltrated with a matrix material. The matrix material is cooled and solidified and binds the hard elements and the inorganic particles in the article.
