The gating system design is not reasonable. Machining allowance, casting the energy and raw material consumption is serious, long processing cycle, low production efficiency, has become a bottleneck restricting the development of the industry.Because of improper design, there is gas, inclusions and other defects, leading to the casting yield and low qualification rate.
Casting machining allowance. This situation is better, but in the purchase of forging simulation software in the enterprise, can play its role is rare, the urgent need forsoftware application training to employees. Large casting defect segregation and inclusions of severe. Because of the lack of scientific design means
The guide, process design staff with experience is difficult to control the deformation,machining allowance Forging General 1 - 3 times larger than that of the foreign.
Simulation software is not widely used. The simulation started earlier in China forging industry computer, although the core computing department development ability, but the overall software package ability is poor, resulting in commercial software development maturity far behind the developed countries, a considerable part of thecalculation of forging enterprises
Computer simulation technology in awe, a lack of trust. Common casting productioncapacity surplus, manufacture of high precision casting is still difficult, the core technology and key products still rely on an entrance. The forging process simulationis a necessary link, castings produced in foreign countries, if there is no computer simulation technology
Operation, not to take orders. Casting crack problems seriously. Large steel castingsand ingot in solidification after the end, in the riser, casting with thick section the macro segregation, coarse grain.
