During the production process of cast iron floor plates, there will be a part of the deviation of the theoretical weight. It should be noted that the deviation of the cast iron floor plates will affect its usage. The design of welding cast iron floor plates should take into account the casting error and machining error, which should generally not exceed 10%. When it exceeds 10%, we need to further appraise the quality of the cast iron plate. Determine whether this cast iron cast iron plate can be put into use.

There will be some product defects in the production process of cast iron plates. As long as the correct methods are used to make up for the riveted plates, the defects of the cast iron plates are important parts that cannot be ignored. The main defects of the cast iron plates include: pores and sand holes , Sand, shrinkage and so on. The defects of cast iron floor plates are dealt with in detail in the "People's Republic of China Machinery Industry Standard" JB/T 7974-2000. The service life of cast iron plates is closely related to defect repair. Therefore, when repairing the defects of the cast iron floor plate, it must be dealt with strictly according to the process requirements.



The basic production process of cast iron floor plate is as following:

1. Cast iron plate blank: Make drawings according to technical requirements, and make wood molds, batching, modeling, drying, casting, sand falling, cleaning and inspection of various parts of the blank according to the drawings.

2. Cast iron plate machining: appearance inspection and marking, processing and inspection;

3. Leveling, manual scraping and inspection of cast iron flat workpieces;

4. Appearance treatment, painting, packaging and storage of cast iron plates.
