ASPECTS REGARDING THE QUALITY OF CAST IRON PRODUCED IN S.C.FONTUR S.A. SUCEAVA
Journal Title: TEHNOMUS - Year 2011, Vol 18, Issue 1
Abstract
The authors analyze the quality of produced cast iron and molded forms from SC FONTUR SA Suceava. For this purpose samples were cast from different batches of samples, from which were made tensile specimens, samples for chemical and metallographic analysis and hardness control. Based on analysis conducted authors show corrections that have to be made to the chemical composition and of cast iron structure to obtain high mechanical strength. Also they give recommendations on improving technology development.

EXPERIMENTAL RESEARCH ABOUT INFLUENCE OF INCLINATION ANGLE DIRECTION UPON THE SURFACE ROUGHNESS IN BALL END MILLING OF OLC45 (C45) MATERIAL
Machining with ball end mills become a very usefull process to obtain pieces with complex surfaces. Possibilities of machining with ball nose end mills represent a adequate process to achieve surfaces with a good quality...
SUPERIOR WASTE RECOVERY IN THE METALLURGICAL INDUSTRY
On the global scale the generating rhythm of the scraps exceeds the natural assimilating capacity of the most regional ecosystems. The numerous studies mode about the good “practices” spotlighted the succe of the ecolog...
MAGNETO-ABRASIVE MATERIALS AND METHODS FOR OBTAINING THEM
Magnetic abrasive particles (MAPs) are crucial to ensure finishing quality and accuracy in magnetic abrasive finishing (MAF) processing. Conventional MAPs consist of ferrous particles and abrasive, such as Al2O3 , SiC,...
OPTIMAL PERTURBATION FOR MIXED CONVECTION HEAT TRANSFER IN RECTANGULAR CHANNEL
We studied the growth velocity perturbation at the entrance of a rectangular channel for mixed convection heat transfer. The flow is bidimensionnel and the fluid is newtonian, incompressible obeying to Boussinesq approxi...
SURFACE ROUGHNESS VARIATION IN BALL END MILLING OF C45 MATERIAL. PART I: INCLINATION OF TOOL AXIS IN FEED POSITIVE DIRECTION
This paper primarily presents important experimental results, about surface roughness variation in ball end milling, for the case of tool axis inclination in feed positive direction. Secondary, using experimental results...
