Besides the combination of automatic watering eggs cooling system for hatching process can significantly reduce the required manpower for watering eggs cooling and biosecurity control risk, the average hatching ratio is 82.06% that can satisfy the requirement of general professional goose breeding eggs incubator.
In order to reduce the demand for manpower, the specification of watering system is 1/2” PVC water supply pipes, and four longitudinal pipe designed for the combination of twelve separate ways nozzle totally, the power of belt-type water supply machine is 1HP.
Start from the twelfth day, the automatic eggs cooling system will conduct regular daily automatic cooling and watering.
The fact shows that the automatic watering eggs cooling system is good enough to bear the working requirement.
Automatic watering eggs cooling process start on the twelfth hatching day and conducted at a fixed time every day.

Therefore, this kind of corrosion liquid dangerous goods must be encapsulated in container shipping isolated from the water and inflammable goods.
We should develop standardization of liquid dangerous goods transport ships and series of large tonnage and environmental- friendly ship in inland water.

M593 shell ‘s main fault is machinery adhering sand, it’s caused by casting wall thick(compared with other parts), takes much longer for molding sand at high temperature(Also, the environment temperature is very high in summer, large water loss in casting mold, the stability on surface of sand mold is lower).Except raise content of FS powder, lower pouring temperature proper can be used to reduce M593 shell’s adhering sand fault.
Conclusion （1）When water content is 3.0％，compactability can be controlled into 36～45％； （2）The influence of green compression strength, followed by is：5FS powder>（4.5coal dust+0.5αstarch）>5coal dust； （3）The influence of shatter index, followed by is：5FS powder>（4.5coal dust+0.5αstarch）>5coal dust； （4）Adding FS powder can add molding sand ‘s strength and tenacity;compare with adding single coal dust, adding little αstarch also can add molding sand ‘s strength and tenacity on the basis of add coal dust
