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.
