银川市场蒸呢机价格基本稳定，市场成交一般。从市场上了解到，近期酒钢、八钢资源到货不多，市场库存小幅下降。据不完全统计，现在银川市场蒸呢机库存 量在0.4万吨，比上周减少0.05万吨。由于蒸呢机厂家目前库存多是前期高价成本，即使目前市场需求一般，也无降价意愿，多是继续持稳销售。需求方面，虽然宁 夏地区今年以来有较多风电项目，但是这些项目多是直接对接钢厂，从市场提货较少。而一些小的桥梁以及其他项目开工较少，市场需求下降。面对目前低迷市场行 情，本地市场蒸呢机厂家多是减少订货，以较低库存来规避市场风险。预计短期内，银川市场蒸呢机价格多是继续以稳为主，蒸呢机厂家需谨慎。

Prices in the Yinchuan market are basically stable and market transactions are general. From the market, we know that Jiuquan Iron and Steel Co., Ltd. and Bagang have not received much resources recently, and the stock of the market has declined slightly. According to incomplete statistics, the square-managed inventory in Yinchuan market is now 0.4 million tons, 0.05 million tons less than last week. Due to the high cost in the early stage of inventory, even if the current market demand is general, there is no willingness to reduce prices, and most of them continue to maintain stable sales. In terms of demand, although there are more wind power projects in Ningxia since this year, most of these projects are directly connected with steel mills, and there are fewer pickups from the market.
