Blank when the cold deformation and work hardening, so die withstand high loads automobile block material, therefore, requires the use of high strength die and prevent wear and bonded using hard lubricating film treatment. In addition, in order to prevent the blank crack, intermediate annealing to ensure that the needs of deformation when needed. In order to maintain good lubrication of the cylinder, the blank may be phosphate treatment. When working with a continuous bar and wire rod, the current section can not be lubricated finished aluminum cylinder engine, is studying the possibility of using phosphate lubrication method. Forging Co., Ltd. Luoyang Super League tells you press forging billet temperature during processing can be divided into cold and hot forging. Cold forging is generally processed at room temperature, forging is machined on the blank metal above the recrystallization temperature. Sometimes also in a heated state, but forging temperature does not exceed the recrystallization temperature is called warm forging. However, this division is not entirely unified in production. Automotive engine cylinder block production _ Super League forging quality assurance (certification) _ Tongling cylinder by the Luoyang Super League Forging Limited. Luoyang Super League Forging Co., Ltd. (www.lysmzg.com) (www.lysmzg.cn) is Luoyang, forging leaders, over the years, the company is implementing the scientific management, innovation and development, the principle of honesty and trustworthiness, and satisfy customers needs. Super League leaders in forging the staff warmly welcome all inquiries negotiations to create the Super League forging a better future.
