摘要： A briquetting roll in which a steel roll body is provided with a peripheral groove having a radially outwardly facing bottom wall which is made up of planar chordal segments and having side walls at the side edges of the bottom wall with one side wall being in the form of an annular segment of a cone concentric with the axis of the roll. Bodies of hard wear resistant material are mounted in the groove, one on each chordal section of the bottom wall of the groove and have the one side inclined to fit the inclined wall with the other side spaced from and diverging from the radial side wall. Wedge bars between the radial side wall and the opposed sides of the segments are utilized for clamping the segments in place in the roll.

摘要： A hardfaced support member and a method of applying a hardfacing element thereto in which the support member to receive the hardfacing element and the hardfacing element have different coefficients of thermal expansion. The invention discloses a method of attaching the hardfacing element by brazing while reducing the area thereof that is subjected to thermal stress thereby eliminating breaking of the hardfacing element when it is attached to the support member.
摘要翻译： 表面硬化的支撑构件和施加表面硬化元件的方法，其中支撑构件接收表面硬化元件和表面硬化元件具有不同的热膨胀系数。 本发明公开了一种通过钎焊来连接表面硬化元件的方法，同时减少其受到热应力的面积，从而消除了表面硬化元件在附着到支撑构件上时的破裂。
