产品介绍

主要生产的特种合金粉末有压制不锈钢粉、MIM用不锈钢粉、预合金胎体粉、金刚石触媒粉、磁粉芯及电感用软磁粉及其他合金粉。

The main production of special alloy powders include pressed stainless steel powder, stainless steel powder for MIM, pre-alloyed carcass powder, diamond catalyst powder, magnetic powder core and soft magnetic powder for inductors and other alloy powders.

还原铁粉以钢铁厂轧钢剥落的废弃物氧化铁鳞为主要原料，焦末为还原剂，石灰或石屑为脱硫剂，按一定比例搭配，氧化铁磷经过烘干、筛分、磁选、球磨、筛分、磁选一系列工序后制得装罐铁鳞，然后装罐装车在隧道窑中,使用炼钢、炼铁和焦化过程中产生的混合煤气加热，在1150℃的条件下进行一次还原得到海绵铁，再经过清刷、粗破、细破、磁选、筛分制得80目以下的一次粉，在钢带式还原炉纯氢气氛下进行二次还原，完成脱碳、脱氧和加工硬化的消除，二次还原后的粉饼经破碎、筛分、合批、包装得到最终不同品种的还原铁粉。

The sponge iron powder is mainly made of iron scale, coke powder and the lime, the mixture of the raw material after drying, sieving, magnetic separation, ball milling, sieving and magnetic separation. Then is heated in the tunnel kiln by gas at 1150 °C, then get the sponge iron bloks, then breaking, magnetic separation and screening get the 80 mesh first reduced powder.

Then the first reduced powder is reduced in the reduction furnace for decarbonization, dexidation and elimination of hardening. The powder cake after breaking,sieving, then finally get the reduced iron powder.

雾化铁粉采用优质废钢为主要原料，在电弧炉中进行冶炼，在冶炼过程中加入不同的合金，在精炼炉中得到成分合格的钢水，经过高压水雾化、湿式磁选、脱水、烘干、冷却、筛分得到雾化生粉，在钢带式还原炉纯氢气氛下进行精还原，还原后的粉饼经破碎、筛分、合批、包装得到水雾化纯铁粉或水雾化合金钢粉。

The atomized iron powder is made of scrap steel, and different alloys are added in the smelting process then get refined in the refining furnace. Then the steel liquid after high-pressure water atomization, wet magnetic separation, dehydration, drying, cooling, screening then get the atomized raw powder.

无偏析预混合粉是为了提高铁基产品的力学性能，在铁粉中加入的C、Ni、Cu、Mo等合金元素，从而改善粉末流动性能、提高制品尺寸精度及力学性能，其主要方法有：粘结混合法与直接混合法。粘结混合法制备原理是以铁粉为基粉与合金元素粉末预混合后，喷入粘结液进行粘结，同时继续混合并烘干使溶剂挥发，之后再加入润滑剂混合均匀并筛分合批得到成品。直接混合法直接将基粉与辅料、润滑剂进行混合并筛分包装得到成品。在生产实际中这两种混合方式都得到广泛应用。

The non-segregated premix powder is to improve the mechanical properties of products. The auxiliary such as C, Ni, Cu and Mo are added to the powder to improve the flow properties of the powder, and to improve the dimensional accuracy and mechanical properties of the products, the main methods are Bonding Mixing Method and Direct Mixing Method. The principle of the bonding method is to spray the bonding liquid onto the mixture of powder and auxiliary materials. The direct mixing method directly mixes the base powder with the auxiliary materials. Both mixing methods are widely used in production practice.
