12 Essential Processes: Step 9- Atmospheric Conditions Can Get You Down

November 1, 2016

At Green Packaging Inc., we’re making it easier than ever to buy rust protection online. Foundries only have one chance to make their first impression on their clients, our products help make sure that those impressions are their best. More than just a retailer, we’re providing resources for those in the metalworking industry on how to stamp out corrosion and eliminate contaminants or practices that cause it.

 

This month we’re covering the ninth step in our twelve essential processes series, monitoring atmospheric conditions in foundries.

Pollutants can hang in the air of a foundry and strike metalwork at anytime, virtually anywhere metalwork is left unprotected. Vapor carries moisture which definitely causes corrosion and pollutants can weaken any resistance a piece may have, so not monitoring the atmospheric conditions can pose problems for any foundry.

 

Foundry pollutants are classified in three ways:

  1. Pollutants from dust-producing operations within the plant.
  2. Gaseous compounds and odors emanating from anything within the plant
  3. Pollutants caused by furnace operations.

 

Dust can be produced from a number of processes within the plant like casting shakeout or grinding of castings. Depending on the process, some dust may carry high amounts of water vapor, iron oxide, clay particles or other unwanted microscopic threats.

 

Discharge from inorganics can be particularly unfriendly to the human nose. Fly ash, metal dust, sand and other inorganic products of work can move slowly through air affecting both foundry workers olfactory senses and the pieces in their presence. Oils and resins can also give off gaseous compounds when subjected to immense heat, again posing problems.

 

Depending on the type of furnace, various emissions can occur. Electric melting furnaces significantly reduce emissions depending on the hood and ventilation in place.

 

Co2 monitors and other atmospheric detectors are a necessity to corrosion prevention in foundries. While virtually all modern foundries have excellent ventilation systems and dust catchers, the failure of one system can have a major impact on oxidation prevention within the working space. Foundry staff should consistently check all detectors and monitors to ensure that atmospheric conditions are at their best levels.
