How to Prevent Problems in Casting Excellent Corn Milling Machine

A corn milling machine includes a benchtop millng machine, a maize corn milling machine and so on. An excellent corn milling machine needs excellent mechanical parameters such as proper match, higher tensible strength or good abrasion performance. What's more, the prevention of key faults in the casting is also very important for a corn milling machine manufacturer. The following passage will introduce the preventing measures of casting excellent machines.

For a corn milling machine manufacturer, the first key fault is the deformation in casting a corn milling machine. If the sub rail of a corn milling machine becomes deformed on the horizontal face or on the side face, here are two ways. The first measure is to apply prestrain method.The second is to do properly stretching at the part of casting with weak tensible strength according to its structure.

The second key fault is the core drift. What is the most important is to fix the rail core and upper core on the lower case with long bolt. If it is unable to realize the fixation, it is better to connect ever isolate sand lump by the outer force in order to counteract the crash of the buoyant force.

The third key fault is the loose tissue Usually, there are fine holes after processing the rail face of a CORN MILLING MACHINE. Because it is the low temperature in melt liquid of iron and not all lead sheets are completely melt. Besides, much more carbon is added into the liquid. Here are three effective measures in the following.

1. Confirm the reasonable carbon equivalent for obtaining metallurgical structure with fine-flake lead according to the thickness of the corn milling machine.

2. Add into the melted iron with a proper amount of alloying elements such as B or Mn.

3. Decrease the pouring temperature and fasten the cooling speed of the thick wall of the corn milling machine in order to increase its degrees of superheat.

The fourth key fault is hard spots and a bad quenching effect. There are two...
