Understanding end user valve approvals Part 11f: castings - visiting foundries

摘要

The molds/cores have been assembled and are now ready awaiting the pouring of the molten metal. Preparation of the ladles can be seen with attention to the pouring lips. Some are short and stubby whilst others declare a more gentle lip is best to pour. The end user should be raising questions on the thermocouple with visible evidence that a new tip is being used. Do check the instruments calibration is valid. Depending on the geographical location of the foundry there will be a diversity of personal protection equipment (PPE) from very good to very poor. Operators with scars can often be seen. What ever the situation make sure you as a visitor have been given the correct personnel protection and stand a suitable distance from the pouring.
