Enhancement of hot forging die life using different methods
Forging dies at high temperatures are under contact pressure, variable mechanical loads and thermal shock, furthermore they should withstand wear and friction in a high level. So, in order to increase die life, the selection of die material, coating and hardness is essential. In this review, various methods used for die life enhancement such as carbide coating, using the super alloy stellite 6 ...
متن کاملEstimation of Spray Lubrication and Die Temperature for Die Wear Life Prediction in Hot Forging
We have been developing a process design CAE system to predict die wear life in the process design stage for the hot forging of steel. Our goal is to reduce production costs by shortening the development period, while maximizing the life of the die. In our system, we use an expression that defines the relationship between die wear, die strength, and friction factors, such as die pressure, slidi...
متن کاملSelection of Die Materials and Surface Treatments for Increasing Die Life in Hot and Warm Forging
In warm and hot forging, the dies are subjected to high contact pressures and temperatures. The selection of the die material, hardness and coating is critical for increasing die life. Recent studies indicate that ceramic dies and various surface treatment techniques represent, in certain applications, cost effective techniques for improving die life. This paper reviews the state of technology ...
متن کامل“the effect of risk aversion on the demand for life insurance: the case of iranian life insurance market”
abstract: about 60% of total premium of insurance industry is pertained?to life policies in the world; while the life insurance total premium in iran is less than 6% of total premium in insurance industry in 2008 (sigma, no 3/2009). among the reasons that discourage the life insurance industry is the problem of adverse selection. adverse selection theory describes a situation where the inf...
15 صفحه اولDetermination of Load and Strain-Stress Distributions in Hot Closed Die Forging Using the Plasticine Modeling Technique
An axisymmetric hot closed die-forging process has been studied by physical modeling technique using the plasticine. To observe the material flow pattern, layers of plasticine with different colors were used. The normal direction to the layers was considered a principal direction. The strain distribution was obtained by measuring the thickness of the plasticine layers. Based on the strain distr...
