实际生产中有时热芯盒温控箱的显示温度过高，即使将温控箱温度调到工艺要求范围内，砂芯固化温度仍低，砂芯强度不足。通过热电偶法对比试验发现，针对热芯盒宽度为320 mm的481热芯盒，热电偶的深度必须要达到芯盒整体宽度的1/3，温控箱的测量值才能与实际温度相接近。

In the actual production, sometimes hot core box temperature control box to display the temperature is too high, even the temperature control box temperature to process the required range, sand core curing temperature is still low, lack of strength of sand core. The thermocouple method through contrast test, according to the hot core box width of 481 hot core box 320 mm, the depth of the thermocouple must reach the core box the whole width of 1/3, the measurement of temperature control box temperature is close to the actual value and.
