The degree of vacuum salt production process is a key process control indicator,which changing directly affects the total system temperature and heat transfer.The high vacuum degree can provide full production capacity for salt equipment,reducing overall energy consumption of production system and improving the thermal budget of salt process.Combined with 600,000 tons per year vacuum salt production line actual operation in Yulin Salt company,it was analyzed that the impact of vacuum degree on heat transfer process and the method for improving the vacuum degree.
