加速隧道窑海绵铁技术改造

SPEED UP MODIFICATION OF TUNNEL KILN DR PROCESS

隧道窑法作为一种传统的直接还的工艺，其工艺简单，但生产规模小、产品质量不稳定，因而缺乏市场竞争力。要使其能够继续生存和发展，必须适应市场需要，充分发挥自身的优势，加快技术改造，强化生产管理，稳定产品质量，提高单机生产能力，降低成本，形成规模经济。

As a traditional DR process, althuogh the process art is comparatively simple, but due to its smaller production scale and instability of its products,so the process is less competitive in the market.In order to maintain its present and developement,it must speed up the modification, enhance production management, stabilize product quality,increase single machine productivity,lower operation cost, and formed large scal economical.
