Abstract: A method for making a roller for hot and cold rolling by placing at least the radial inner portion of a hard metal ring in a mold cavity, heating the mold cavity and the hard metal ring and casting therearound, at least at the inner part of the radial sides of the inner ring, an annular hub of ferrous alloy. After casting, the hub and the hard metal ring are cooled, the hub shrinking more than the hard metal ring so as to exert compression forces thereagainst to hold the same in place.
Abstract translation: 一种用于通过将至少硬质金属环的径向内部部分放置在模腔中来制造用于冷热轧辊的方法，加热模腔和硬金属环并至少在其内部进行铸造 内圈的径向侧面，铁合金的环形轮毂。 铸造后，轮毂和硬质金属环被冷却，轮毂收缩多于硬质金属环，以便施加压力以将其固定在适当位置。

Abstract: A roller for hot and cold rolling is made by taking a hard metal ring, the cross-section of which decreases radially outwardly, and casting around the inside and at least the inner part of the radial sides thereof an annular hub of ferro alloy. After casting, the hub and the hard metal ring are cooled, the hub shrinking more than the hard metal ring so as to exert compressive forces thereagainst to hold the same in place.
Abstract translation: 用于冷热轧的辊是通过取下硬质金属环，其横截面径向向外减少，并且在其内部和至少其径向侧的内部的内部铸造有铁合金的环形毂。 铸造后，轮毂和硬质金属环被冷却，轮毂比硬金属环收缩，以便在其上施加压力以将其保持在适当位置。
