Cast Iron Plate Made In China

By:


Cast iron plate is also called as cast iron flat. Cast iron plate is used for workpiece detection. It is indispensable basic tool in mechanical manufacturing.

In China, you could find many types of cast iron plates, such as inspection plate, crossed flat, measuring platform, assembly plate, welding plate, and basic plate etc.

Cast iron plates are usually made by grey iron ASTM A48 CL 30, CL 35, CL 45, ductile iron ASTM A536 60-40-18, 65-45-12, 70-50-05, 80-60-03. They have higher wear resistance, corrosion and pressure resistance.

Maintenance of cast iron plates

1. Cast iron plate should be installed in ventilated and dry environment, moreover, it must be far away from origin of heat, corrosive gas and liquid.
2. Fixed all support points to ensure stability of plates.
3. In order to prevent the deformation of cast iron plate, after used, remove the workpiece from the plate.
4. Clean working face, then paint with anti-rust oil to prevent the surface rust of cast iron plate.
5. The weight of the workpiece must not be more than the plates rated load.

Sand hole defects of cast iron plates

As for the resin sand molding, although the intensity of this molding is very high, but some iron casting defects such as sand holes and clip sands will still appear during making cast iron plates.

It is mainly because sand cleaning is not thorough. There is residual sand in the mould. Secondly, the washing of iron liquid to the mould wall could cause the sand holes either.

In order to improve the sand hole defects, the iron foundries should use the ceramic pipes for the cast gates. The ceramic pipes are easy to use, they have smooth flow and resistance to molten iron. It can improve the layout of gating system, casting quality and finished product ratio, and avoid sand holes and clip sand defects in iron castings.
