Satisfac- tory experimental results and good products were obtained by means of...

This paper discussed the casting technique of the winding barrel used on metallurgical crane of 140 ton capacity for lifting and transferring spout ladle or ingots etc. Qualitative problems encountered during casting of the winding barrel such as shrinkage hole, inferior in graphite spheroida- zation and non-metallic inclusions are similar to those emerged in casting process of other thick-walled spheroidal graphite iron castings. Satisfac- tory experimental results and good products were obtained by means of rigid form constructed with chilling materials.
