Custom Ladles Designed By Foundrymen For Foundrymen
\n<\/strong>Nearly all of the ladles manufactured by D&E Foundry Ladles, a division of TeeMark Corporation, are custom made, from design and engineering right down to production. Our custom ladles are either built to customer specifications or are a standard design that is modified to meet specific needs.<\/p>\n

Our custom and modified ladles make the most practical sense for companies in the foundry industry. This is in part to special features working best when they are “built-in” rather than “added-on.” Ladle balance, for instance, can be affected by modifications occurring at the end-use foundry; balance issues are best handled at the original factory. TeeMark, as the parent company, and D&E, as the manufacturing division, take ladle customization and development extremely serious. One of the numerous reasons only the best designers, engineers and foundrymen are retained as part of the TeeMark\/D&E team.<\/p>\n

As all facets of the foundry industry change, you can rely on TeeMark and D&E to stay ahead of the curve, developing sound solutions for advanced problems. So if you do not find the correct ladle configuration to meet your needs, contact us, we would be pleased to work with you.<\/p>\n

Process Ladles Designed By Foundrymen For Foundrymen<\/strong>
\n Tight Cover Mark IV Ductile Iron Treatment Ladles<\/strong><\/p>\n

Reduced Alloy Costs<\/span>
\nIn an open ladle, up to 70% of the magnesium present in the alloy is lost into the atmosphere in a great cloud of magnesium oxide vapor. Because the Tight Cover ladle is a closed vessel, very little oxygen is present during the reaction. The Mg vapor remains in the ladle environment instead of being lost as MgO. As the ladle fills, this Mg is stirred back into the bath.<\/p>\n

Alternative to Emission Control<\/span>
\nUnder good process controls, the magnesium oxide emissions from our Tight Cover ladles is less than 5% of that of an open ladle. The ladle has been accepted in a number of states as an alternative to dust collection in the treatment of ductile iron. The savings of the initial cost and upkeep of a dust collection system are quite substantial.<\/p>\n

Elimination of Cover Material<\/span>
\nD&E’s Tight Cover ladle is a designed to coordinate the fill time wit the reaction time for optimum Mg recovery. Cover steal used in open ladles to delay the Mg reaction is not recommended because it throws off this critical time and reduces the ladle’s efficiency.<\/p>\n

Savings include not only the material and handling costs of the cover material, but also the energy costs to melt and superheat it.<\/p>\n

Controlled Venting<\/span>
\nDuring the reaction the Mg boils, generating a pressure of over 200 psi. The Mark IV ladle has a controlled venting system to assure safety and excellent recoveries.<\/p>\n

Energy Savings<\/span>
\nBecause the Tight Cover ladle is covered and insulated its head loss is about half that of an open ladle. Tap temperatures can be reduced by as much as 100\u00b0F. In many cases these lower tap temperatures mean an increase in the number of tons that can be melted.<\/p>\n

Removable Bottom<\/span>
\nThe Tight Ladle has a removable bottom allowing refractory in the reaction zone to be repaired without removing the good refractory in the upper part of the ladle. Order a spare bottom to have lined and ready for hot or cold changes whenever needed.<\/p>\n

No Slag Build-Up<\/span>
\nThe large pour-out spout lets you remove slag each time the ladle is emptied without having to turn the ladle upside down.<\/p>\n

Longer Fade Time<\/span>
\nThe limited amount of oxygen in the closed vessel increases fade time. Because of reduced heat loss and increased Mg fade time, iron can be held longer in the D&E TIGHT COVER\u2122 ladle, avoiding pigging and pour packs that delay production.<\/p>\n

\n

Improved Product Quality<\/span>
\nThe simple fact that the operator cannot see the metal level inside the covered ladle, means that the iron must be measured (usually weighed) as it is poured into the ladle. The iron is metered into the ladle through a critically sized orifice to optimize the magnesium reaction. These factors, along with the increased Mg fade time, greatly increase control over the treatment process and result in improved quality, a more consistent produce, and reduced scrap.<\/p>\n

Size Range<\/span>
\nStandard sizes range from 600 to 20,000 pounds iron capacity. Larger and special sizes are available.<\/p>\n
