The shell-type coated sand casting is heated, and the phenolic resin coated on the outer surface of the sand begins to melt. The temperature at which the sand is bonded together is called the melting point of the coated sand casting.
Inspection method: (ZBG39005-89):
First, the temperature on the metal plate surface of the melting point analyzer is increased from 60 to 130 degrees Celsius in the axial direction, and is divided into a plurality of different temperature intervals, and the temperature of each interval should be kept constant.
During the inspection, a special strip of coated strips with a thickness of 1.5 mm and a width of 20 mm was evenly sprinkled on the above-mentioned metal test plate surface, and kept for 1 min to start melting, and then a stable 0.05 MPa air was used. Blow the nozzle and move it along the guide rod of the instrument at a constant speed to blow off the uncoated shell sand.
Finally, the melting point of the coated sand casting is determined by the temperature at which the amount of sand on the low temperature end plate is 50% or more.
Each sample was measured 3 times, and the average value was taken as the test result.
