铸铁平台的铸件要一边挖一边进行清砂的工作，清砂形式有人工清砂及抛丸清砂。人工清砂费用低，有些局部处理的不是很干净。而抛丸清砂则相反，费用高，检验平板表面清理的非常干净。
焊接平台进行抛丸清理的理想温度最好是接近环境温度，但每家铸造厂的冷却时间不尽相同，因此铸铁平台铸件进入抛丸室的温度差别也很大。因此抛丸机在设计时，应考虑到用户生产可能的最高温度，假设客户需要对如此极端高温的铸件进行清理，设计的抛丸机就必须符合这样的要求，如此才能减少日后的维修，停机和其他包括操作安全隐患等问题。一般铸造厂用的抛丸机可处理表面温度高度100°C左右的铸件。在这样的温度下，就不适宜用橡胶履带输送式抛丸机，而要选择用钢履带式或锰钢履带输送式抛丸机。在高的温度，如高达175°C,时，就必须辅以特殊耐高温的密封，幕帘和提升机履带。
铸铁平台铸件在铸造出来以后在地坑中要呆上合适的时间，时间的控制要根据平台的吨位来定，吨位越大在地坑中呆的时间就应该越长，要不铸件没有放凉就挖出来轻微的是变形，比较重的损失就是铸件发生断裂。
Knowledge Points of Casting Sand Cleaning
for Cast Iron Platform
Castings of cast iron platforms should be
cleaned while excavating, in the form of manual and shot blasting. Artificial
cleaning costs are low, and some local treatment is not very clean. On the
contrary, shot blasting is expensive, and the surface of the test plate is
clean.
The ideal temperature for shot blasting
cleaning of welding platform is close to the ambient temperature, but the
cooling time of each foundry is different, so the temperature difference of
cast iron platform casting entering shot blasting chamber is also great.
Therefore, the design of shot blasting machine should take into account the
highest possible temperature of production, assuming that customers need to
clean up such extremely high temperature castings, the designed shot blasting
machine must meet such requirements, so as to reduce future maintenance,
shutdown and other problems including operational safety risks. The shot
blasting machine used in foundries can handle castings with surface temperature
of about 100 C. At this temperature, it is not suitable to use rubber
caterpillar conveyor shot blasting machine, but to choose steel caterpillar or
manganese steel caterpillar conveyor shot blasting machine. At high
temperatures, such as up to 175 degrees C, special heat-resistant seals,
curtains and elevator crawlers must be supplemented.
Cast iron platform castings in the pit
after casting to stay in the appropriate time, time control should be
determined according to the tonnage of the platform, the larger the tonnage in
the pit to stay in the longer time, or the castings did not cool out to dig out
a slight deformation, heavy losses is that the casting fracture.
