Features:

1. Design flexibility, the greatest design choice for the shape and size of casting, especially the shape of complex and hollow section parts, casting steel parts can use the this unique process to manufacture;

2. Metallurgical manufacturing has strong adaptability and variability, can choose different chemical composition and organizational control, can adapt to a variety of different engineering requirements;

3. The isotropic and the overall structure of cast steel parts is strong, thus improving the engineering reliability;

4. The weight can vary over a wide range (1-20T).

Production:

1. Electric induction furnace melting process;

2. Molding sand and mold melting technology;

3. The advanced casting process overcomes the defects such as insufficient pouring, porosity, shrinkage, hot cracking, clay and deformation in casting engineering.

4. Annealing and normalizing heat treatment process is used to increase the plasticity of the product and not easy to crack.

Inspection and testing:

1. Using DC or half-wave rectification fixed, portable or mobile magnetic particle flaw detection machine, using contact method or yoke method, dry method continuous method or wet method continuous method, to detect local or regional castings;

2. Find defects in time to dig, turn, shovel measures to repair welding, while controlling delayed crack;

3. Inspection should be carried out with the naked eye, only in 001 and 01 level detection can use no more than 3 times the magnifying glass.
