Casting description:

Sliding block large carbon steel casting is mainly used in forging and press machinery. The sliding block steel casting’s shape, size, dimensional tolerance and machining tolerance shall be in accordance with the drawing. The steel casting test method,chemical composition analysis adopt chemical analysis or spectral analysis.Test block for chemical analysis or spectroscopic analysis shall be made in the casting process.Casting surface inspection, shape and dimension inspection should be selected with accuracy testing tools, gauges, templates or lineation inspection. Nondestructive testing is divided into penetration testing, magnetic particle testing, ultrasonic testing, radiographic testing, pressure tight degree experiment,these testings are all decided by the customer requirements.

 

  Cast steel has a high melting point and a corresponding high pouring temperature. The interaction between molten steel and mould material at high temperature leads to sand sticking defects easily. Therefore, the artificial quartz sand with higher refractoriness should be used as the casting mold, and the coating made by quartz powder or zircon sand powder can be brushed on the surface of the casting. In order to reduce the gas source, improve the fluidity of molten steel and casting strength, most steel castings are cast by dry or quick drying type, such as CO2 hardened water glass sand. Steel castings shall be used after heat treatment.

 

In the long-term production of carbon steel castings,the defects mainly are sand hole, sand burning, shrinkage, sand inclusion,scab, swell, etc.. Strictly control the sand performance and improve the sand core surface’s strength and compactness, reduce burr,sharp angle, and sand cut.
