subject”, persisting in taking the researching principle of “never
copy, attaching great importance to innovate and stride”,
adopting the researching method of “researching production
process must be combined with researching equipment”,
persisting in taking the aim of “international advanced
level and innovating China’s national brand” are our some
realisation for successfully researching and developing new
roll replaced forging by casting under the pressure of heated
market competition day by day of late twenty years.
