像2500吨纯水式锻造水压机机座这样的重型钢铸件,过去我们车间是依靠了炼钢厂的平炉,在炼钢厂造型浇注的(因当时我车间平炉熔量不够)。在本车间浇注这样60多吨的重型铸件还是第一次。平炉扩大炉膛以后,已解决了钢水问题,但车间吊车的能力不够,为解决解一问题,我们采用了活拆砂箱造型法,浇注以后就地拆箱和清理,终于圆满的解决了制造问题,并且又用这个方法铸造了1200迥旋破碎机底座。
Heavy-duty steel castings like the 2500-ton pure water forged hydraulic press stand used to be relied on open hearth in a steel mill and cast in a steel mill (because of the lack of melting capacity in the open hearth at my time). In the workshop pouring more than 60 tons of heavy-duty castings for the first time. After expanding the furnace hearth, has solved the problem of molten steel, but the workshop capacity of the crane is not enough, in order to solve a problem, we use the live demolition sand box molding method, after pouring and unpacking and cleaning, and finally satisfactorily solve the manufacturing problem , And in this way has also cast a 1200 rotary crusher base.
