Ore dressing mill flange process improvements

2019 - dressing ball mill flange process improvement scheme 11 - 08 lyricist Zhang Jingtao ( West heavy) A casting plant for many years, product technology background often undertake processing used in casting, processing flange is the more common type of ball mill, the flange diameter of 3400 mm, 100 mm wide and 80 mm thick, belong to a kind of large castings. According to the original production technology, wood type samples can be divided into two and a half, the ground USES sample model, it will produce a lot of difficulties in modelling, and larger, so the production process of the cost consumption in order to solve this problem, put forward the following solutions. Second, the improvement program will be on the surface of the original sample shape is changed to core model, the new and old technology comparison is as follows: three, solve the problem of using cover core set of core technology can solve the problem of the following quality and process. 1, compared with the sample molding process, the process on the amount of sand dropped sharply, but also saves the use amount of resin and curing agent, provide a reliable basis for the efficiency of authors. 2, the craft production efficiency is high, the production efficiency is twice as much as the original sample molding, indirectly, reduces the labor intensity of workers. 3, the new process has greatly shortens the time of flange manufacturing for other castings production provides plenty of time.
