Recently, the Ministry of Industry and Information Technology and the China Federation of Industrial Economics jointly announced the second batch of individual champion manufacturing enterprises and individual champion product lists. KOCEL’s heavy cast steel gas turbine recommended by Yinchuan Economic and Technological Development Zone has won the national individual champion product award, which marks that Ningxia has achieved a breakthrough in this field.
It is reported that the steel casting product applied by KOCEL Group includes turbine cylinder, exhaust vane retaining ring and other castings, which are supporting steel castings for heavy gas turbine thermal generator set. The product uses resin sand molding technology: in order to optimize the casting process and shorten the development cycle, the casting process design adopts virtual simulation technology (MAGMA application), the casting filling and solidification process simulation has been completed in advance; modeling uses wood-like real sample method, mold making employs five-axis CNC machining technology; melting process uses computer-controlled liquid steel refining technology and rapid detection and analysis; heat treatment uses large natural gas furnace, temperature difference controlled at ± 10 oC; applying high-precision spectral analysis, gas analyzer and non-destructive testing technology. To this end, KOCEL relies on state-level enterprise technology center to set up the Institute of Steel Technology with production technology leading in China and even in the world.
