However, the computer simulation is also obviously insufficient. First of all, the correctness of the simulation depends on the established model, and the model must be corrected through experiments.
In addition, many casting defects can

Abstract
The invention relates to a visible molding technique more exactly a 'able to be seen' molding technique. The invention begins with adopting calculating the coagulating and mould filling process by numerical simulation techniques to forecast and reduce (or even eliminate) the normal abscess, rarefaction, heat cracking and other defects on the molding; and then real-time monitor the molding filling and coagulating process with three-dimensional X-rays to penetrate the metal liquor movements in mould cavity directly sighting the air pores, inclusion and other defects which is unforeseen by simulation; finally by integrating the simulating and observation, optimize the pouring system design so to produce the final fine moldings. The invention provides the china molding industry with a visible molding technique which achieves power and consumption saving, alleviating the pressure on environment and resource short, increasing the molding passing rate and technical product rate, lower the processing recess and being close to final product. It is adapted to molding processes of normal sand mould molding, accurate molding of different alloy and size.
Description
technical field [0001] The invention belongs to the field of casting, in particular to a visual casting method. It is suitable for the forming process of castings of various alloys and various sizes and specifications such as ordinary sand casting, precision casting and metal casting. Background technique [0002] The added value of China's manufacturing industry accounts for about 37% of the country's GDP and is the mainstay of the Chinese economy. Casting is an important link in the equipment manufacturing industry, providing parts for the machinery manufacturing industry. my country is gradually becoming the world's casting production base, and has become the world's largest casting production country since 2001, but my country is not a casting power. This situation is mainly due to the backward technology, most of the foundry production relies on experience, especially the gating system design has been using the old technology decades ago. Casting production has high ...
