awkward spaces with castables. Large blocks tend to crack as a result of something called heat differences in material‚ or temperature differences in material in other words‚ which is a very powerful natural phenomena. But hey no worries Mate‚ we still have firebricks here luckily (firebricks those nice little fragments) for making the dome part properly (read more about heat differences in materials - basically it deals with shrinking of cooled down edges and also surfaces while middle’s still hot expanded)

GLIGORIJEVIĆ Jeremija JEVTIĆ Djuro BORAK Abstract. Materials and process selection are key issues in optimal design of industrial products. Substituting and selecting materials for different machining parts is relatively common and often. Material selection is a difficult and subtle task‚ due to the immense number of different available materials. From this point of view paper deal with a set of major gear design criteria which are used for gear material selection. The main gear design criteria are:

mechanical deformation process of different materials by three tests: tensile test‚ impact test‚ and fracture-toughness test. The materials evaluated in the tensile test were annealed 1045 steel‚ cold rolled 1045 steel‚ 2024-T4 aluminum and cast iron. 2024-T4 aluminum is concluded to be most ductile (25.7 % reduction in area) and cast iron the most brittle (123 MPa). Effects of cold rolling in 1045 steel are apparent‚ as it has the highest strength among the materials tested (402 MPa yield strength). Impact

MATERIAL REQUIREMENT PLANNING MRP is a computerized ordering and scheduling system for manufacturing industries. It was developed in the 1950’s but became popular only in the 1980’s.It stemmed from Enterprise Resource Planning (ERP). It essentially is a backward scheduling system. It utilizes the bills of material data‚ inventory data and also the master production schedule to project what material would be required along with the quantity in which it would be required.MRP facilitates in placing

Material & Immaterial Space The concept of space has massively changed since the evolution of mankind. Spaces that were defined by material‚ culture‚ context and climate have now been redefined by other factors such as technology and new invincible forces. Based on Jonathan Hill’s Immaterial Architecture‚ the book that traces the changing science of space and the forces that define it‚ i.e.-material aspect (presence of matter) and the immaterial aspect (absence of matter)‚ this paper also

Chapter 6 DIFFUSION IN SOLIDS • How does diffusion occur? • Why is it an important part of processing? • How can the rate of diffusion be predicted for some simple cases? • How does diffusion depend on structure and temperature? Driving force for movement In general‚ force is a position derivative of energy (F = - dE/dr). In other words‚ if there is any energy difference in space‚ there is a force which will act on matters - Force will move things. (ex1) Potential energy by gravity:
