Definition

| DC Furnace |
An EAF that has a single electrode and uses direct current. |
| Dead Freight |
This word was originally used in defining certain conditions in ocean freight. The term, however, has been carried over into rail car and truck freight lingo. Originally, it meant freight that was paid to guarantee certain storage space in a vessel but was not all used by the shipper. Inasmuch as the shipper had guaranteed to use the space but had not used it, he must pay for it anyway. In carload and truckload shipments dead freight refers to the difference between the actual weight shipped and the lowest minimum weight chargeable to obtain the lowest freight cost.

| Deadhead |
This term when used in truck transportation - refers to the condition in which a truck is moving without a load. This movement is usually a return to a point of origin where its intial load was made or back to "home terminal" where it will await instructions for its next haul of material. Trucking companies attempt to avoid deadhead situations because they increase their costs without resulting in any revenue. To counteract deadhead movements, trucking companies attempt to "backhaul" movements. Backhaul is not always back to the initial point of origin but may be a move in the general direction or into a geographic area where another load may be found. We should look upon "deadhead" as an empty truck moving on the highway. Deadhead, in railroad parlance, means a load moving without the assessment of freight charges (usually "company material"). |
| Debit |
A record of indebtedness on the part of ourselves or one of our customers. This as opposed to "credit" which is a record of the amount in favor of ourselves or one of our customers. Again the term debit should be carefully used and should be referenced that it is clear as to whom the indebtedness applies (See "Credit.")
|
| Delivered |
This term usually means the same as "at the destination" except when the term basing point is introduced in order to price material in the fashion so required. When the word delivered follows a certain number of dollars, it usually means that the seller will arrange for the means of transportation requested by the buyer and will also arrange to have the material delivered or taken to the destination at his cost. Negotiations that are not a "delivered" basis are on a "shipping point" basis. |
| Delivery Date |
In barge and railroad car shipments, it is almost impossible to predict or demand a given delivery date. In truck transportation, the matter is somewhat easier but still not without pitfalls. |
| Demurrage |
In domestic shipping demurrage is a penalty charged to shippers or receivers of freight by the carriers, usually at a stated amount per car, per truck, or per barge, per day for detention of the vehicle beyond the free time provided for loading or unloading. |
| Dendrites |
The acicular shape during the freezing of molten steel. Has the appearance of sharp fingers.
|
| Density |
This term carries with it the usual definition. It also, in a large number of cases when used referring to scrap shipments, refers to the relative density of the grade under consideration. Two shipments of the same grade of scrap may have different densities, the one being prepared in such a way that the material is more compact and would weigh more per cubic unit. Generally speaking, the higher the density the more disirable the material. |
| Deoxidization |
The removal of oxygen from the steel usually with aluminum or silicon. |
