This is just a starting point; more participation from everyone will make things even more lively. Haichuan becomes even better with you here; we welcome everyone to engage more in discussions on this forum. It’s hot in July, so be careful to prevent fires. ---------------------------------------------- Recently, the M701J type gas turbine developed by SINOMACH Heavy Equipment successfully passed the final inspection of its turbine cylinders, which were then sent to the customer’s site. With this, all 8 units manufactured by SINOMACH Heavy Equipment have been delivered. The company has thus become the first in China to master the manufacturing technology for high-end heavy-duty gas turbine castings of E, F, H/J grades and to achieve mass production, making significant contributions to the localization of world-class H/J grade gas turbines. Heavy-duty gas turbines are core equipment in the fields of power generation and propulsion; they reflect a country’s industrial level and are regarded as the \"pearl on the crown\" of the equipment manufacturing industry. They are widely used in power generation, aviation, shipbuilding, petrochemicals, and other sectors. The R&D team at Second Heavy Equipment, which is part of SINOMACH Heavy Equipment, made full use of numerical simulation techniques and lean management tools to carry out simulations of multi-field interactions related to filling, solidification, and stress, as well as value stream analyses for the entire manufacturing process. By doing so, they overcame key manufacturing challenges associated with producing high-quality thin-walled, complex cast steel components for heavy-duty gas turbines of H/J grades. This has provided important support for the localization of heavy-duty gas turbines in China and for ensuring the country’s energy security.
