“…In the present work molten wax mixed with given proportion of denser sand and lighter wood particles, is considered as the simulation medium for the study of particle distribution in a melt solidifying in a rotating mould. Use of the simulation mediums to study the behaviour of real metallic alloys through laboratory experiments is already in place [34]. In particular, the present work draws a parallel from the work reported by Gao et al [35].…”

The paper undertakes to demonstrate dispersal of particles with varied densities in a melt solidifying in a rotating mould, through laboratory experiment. Molten wax, wood and sand particles were considered for the purpose. Mixture of the three, in pre decided proportions, was poured into a refractory lined, split mould, rotating about its vertical axis at different speeds and the melt was allowed to solidify under the influence of the resulting centrifugal force. Slices of the casting so obtained, were examined using an optical microscope. Also, temperature and viscosity profiles of the melt, as well as the velocity and position of the particles in the melt at any instant of time, were analyzed, with the aid of relevant mathematical equations. The solidified wax was seen to have heavy sand-particles at the outer most surface and the thickness of the particle-rich-zone decreased with the increase of mould-rotational-speed. The analytical and experimental findings were in good agreement. The investigation, also, established significant contributions of combinations of 'speed of rotation' and 'mould size' towards graded distribution of particles in the solidified melt leading to gradation of properties in the resultant casting.

“…As in the previous work on the barrel-roll piercing, Assel elongation, and tube extrusion, carried out by Blazynski et al [l-31, the estimate of the effects of redundancy is made by studying the patterns of deformation developing in specially marked model (wax) material billets [4], and the associated with them variations in loads and torques are assessed by measuring these parameters when piercing lead billets [5]. The effect of pass geometry on the incidence of axial wall shearing, cavitation in front of the plug point, and general distortion of structure are examined by varying plug profiles in accordance with the precepts of the CRHSconcept of constancy of the ratios of homogeneous strains along the pass, developed by Blazynski in the "sixties", and described in detail in Ref.…”

The relationship between redundant macroshearing and force parameters, related to a rational pass design, in a rotary 2-cone roll seamless tube piercing process was investigated. Wax and lead billets were pierced in a range of working conditions involving decelerated, uniform and accelerated rates of flow, different plug advances, and four values of feed angles. The likely optimal piercing conditions are indicated.

Tubular wax and lead specimens were elongated in an Assel, 3‐roll oblique system to estimate the incidence of unnecessary macroshear strain, on the one hand, and the correlation between force and torque parameters and the redundancy of the system on the other. The effect of pass geometry on the material response was tested against the conditions created by the “theoretical” roll profiles – designed in accordance with the CRHS concept – and those produced by the standard, industrial passes.
