Development of Casting Technique on the Roll Housing Casting Producing Wide-thick Steel Plate
In this paper,the main stress part of the 5-meter wide-thick plate rolling mill,the roll housing casting with 490 tons was introduced,and According to its structural and technical requirements,a casting technology with reasonable parameters and convenient operation was developed by analysis of its technological characteristics,design of its technology,application of Magma solidification simulation software and verification and optimization of the process.The result is that the roll housing casting by ultrasonic test and magnetic test according to the standards after rough machining completely satisfied for the quality requirement of the casting.
