Abstract

The alloy phase diagram and thermophysical properties of the modified medium manganese steel were analyzed with the Jmatpro software to determine the initial pouring temperature.According to the material and shape of the liner

a inclined pouring withwaved chill casting process was designed.The mathematical

geometry and finite element temperature field models of the jaw crusher liner in the inclined gravity sand casting during solidification process were established.By finite element simulation software ProCAST

the temperature field of the casting process was simulated and calculated.Results show that

during the eutectic transition process

the released heat cannot be dissipated out smoothly

resulting in the flattened cooling temperature curve gradually.By comparing the speed of five key points on the cooling curve

it is found that with inclined casting with cold iron at the central location

the central position of component is solidified firstly

and then the both sides solidified

realizing sequential solidification

and shrinkage porosity（holes）are eliminated.
