链篦机——回转窑工艺
Grate kiln process
链篦机——回转窑工艺是目前国外生产铁矿球团的主要手段之一，国内许多冶金企业对这种工艺进行了引进和开发。用这种工艺生产球团的优点：
1、生产效率高，成本低。
2、与烧结机相比返回料极少，粉尘低，有利环保。
3、球团的抗压性能与品位较高，能满足大型高炉对炉料的要求。
本公司采用特殊稀土处理铸造工艺和机械加工方法，生产链篦机、回转窑、环冷机等设备中的关键耐热钢部件。如链节、篦板、链轮、铲料板、滑轨、侧板、小轴、定距管、流槽体、窑头窑尾卡口铁、筛体梁等。
As the main method to produce iron ore pellets, the grate kiln process owns many advantages:
1. High production efficiency and low cost.
2. Less returns and dusts.
3. Better compressive properties as the charging for large blast furnace demands.
The key heat-resisting alloy steel parts for chain grate machine, rotary kiln and annular cooler are made by the special rare earth treatment casting and machining process. The parts includes: link, comb board, chain wheel, spading plate, slide, side plate, axis, spacer tube, flow tank, bayonet iron for kiln head / kiln tail, sieve beam, etc.
