Novelis composite ingot casting method:principle,process and application;

Utilizing stress calculating formula of thick-wall cylinder to which only inner pressure has been applied,allowable maximum size of metallic prefabricated piece enveloped location in liquid-solid composite casting has been calculated.

It was showed that The metallurgical connection was formed because of the diffusion reaction,interface reaction and formation of the new compounds during the composite casting.

Fabricating lining boards for ball mill by means of bimetal casting process;

By adopting a compound casting method,we have developed a kind of high wear resisting crushing bar,with low carbon steel interior,high chromium casting steel exterior.

In order to solve the mine scaleboard problems of the erosion, cavitation and abrasion, we excogitated a kind of the bimetal compound casting scaleboard though optimizing the chemical contents and casting technology, and adjusting the heat-treatment parameters, which improved the using life about 50% than the high manganese steel, and was higher 30% than the mid - carbon bai-nite steel.

Proposed at present grades the question which the breaker tooth meets,introduced a general solution way,as well as SSC trying another method,elaborated with emphasis SSC uses the compound casting craft type,the craft step,the advantage and the use effect,summarized the compound casting craft use significance.

Hydraulic simulated test of transitional zone of dipper teeth for bimetal composite cast;
