QT600-3 Ductile Iron Castings Delivered to Russia

In June,2016,six types of QT600-3 Parts for Milling Machines were delivered to Russian Mill Steel Plants.This was the third repeated orders.The ductile iron castings were transported to Shanghai,then to Manzhouli via trucks ,finally to the inland destination,Russia.

The series of graphite iron castings are composed of six types,called intermediate plates, gate plates.The initial development for such kind of products was not easy.

 

We’d like to illustrate the following 6 points:

1.For the parts,the length is about 1000mm,width is just 200mm,the rib is only 8mm thick.We adopt resin sand cast process.Due to big section thickness difference from 8 to 20mm for long castings,the solidification speed was very different.We improved our riser and gating system of the parts many times,and finally the shrinkage and porosity issues were solved.

 

2.At the first order step,due to the assembly information and working condition were not known,we just did general size inspection.When the first batch castings arrived at the site,it was found that the assembly gap was big due to the variation of the arc face.We immediately adjusted the patterns and checked each piece with gauges.Meanwhile,we ground and machined some key faces to assure every piece can meet site assembly requirement.Please find the photos of finished parts as below:

3.We did annealing treatment for QT600-3 castings to relieve the stress of complicated castings to assure the safe and reliable service.

4.The hardness of the parts is about HB200 and the microstructure is mainly pearlitic.

5.After the whole process:Production-Inspection-Feedback from clients-Adjusting Production Process-Improving Inspection Method-Repeated orders,our production and inspection engineers deeply realized that:

5.1:Regard the castings as the artworks during each production and inspection process.

5.2:During inspection process,we have to not only check the parts piece by piece ,but also fully understand the working condition of workpieces,then find an effective inspection way to shorten the lead time,to be beyond the expectation of our customers.
