On some problems of producing grinding media by cross

Balls for ball mills can be produced by die forging, rolling and casting methods. The rolling of balls can be realized as skew or cross rolling. This paper describes a new method for producing balls by cross wedge rolling combined with upsetting. Special emphasis is put on failure modes occurring in this process. Typical defects in balls produced by the new technique are

Furnaces: principles of design and use

01/01/1982To calculate the heating and cooling times of thin bodies or materials with high diffusivity (e.g. aluminium), the following equation 9, 10 can be used:. θ = {w ρ c p / 3.6 h}. ln {(T f − T 0) / (T f − T θ)} (θ time (h), w = weight of the body (kg/m 2 of exposed surface), ρc p = specific heat (kJ/kg K), and h = heat-transfer coefficient (W/m 2 K).)In the above equation the furnace

Ring Rolling

Ring rolling is a particular category of metal rolling, in which a ring of smaller diameter is rolled into a precise ring of larger diameter and a reduced cross section. This is accomplished by the use of two rollers, one driven and one idle, acting on either side of the ring's cross section. Edging rollers are typically used during industrial metal rolling manufacture, to ensure that the part
