公司铸造厂自1994年在冲天炉熔炼设备能力不足的条件下,通过独到的工艺方法,克服大断面球墨铸铁件由于冷却缓慢产生的石墨漂浮、中心球化不良等致废铸造缺陷,研制成大型厚断面球铁机壳——重达5吨、大断面尺寸为280mm 的铸态铁素体球墨铸铁件——高压缸氧
The foundry foundry has been manufacturing large-sized (medium-sized) castings due to the slow cooling due to the lack of capacity of the cupola melting equipment under the conditions of the original technology, through the unique process to overcome the large-scale ductile iron castings due to slow cooling of graphite floating, Thick cross-section ductile iron chassis - Heavy cast iron ferrites weighing 5 tons and 280 mm in cross section - High pressure cylinder oxygen
