The furnace is then tilted forward so that the lance is above the charge, and the charge is melted using an oil or natural gas burner that is inserted near the top of the furnace. [6] Once the charge has been melted, the furnace is tilted back into the blowing position and oxygen is blown into the bath. [6]
The slide room concept had been around in the RV industry since the 1970s and power slide outs since 1990, [21] but this was Sunline's first application of them. 50,000th Sunline, a 2000 T-2370. 8/26/99. The Saturn travel trailer line was launched in 1996. [22]
By 1970, half of the world's and 80% of Japan's steel output was produced in oxygen converters. [3] In the last quarter of the 20th century, use of basic oxygen converters for steel production was gradually, partially replaced by the electric arc furnace using scrap steel and iron. In Japan the share of LD process decreased from 80% in 1970 to ...
In market there are many special converters [1] [2] [3] that solves the problem of connecting a car with European wiring to a trailer with North American wiring. What most of these converters do is to bring together the turn signals and stop lamp signal from a three-wire solution using 54, L and R into a two-wire solution using L54 and R54 ...
Wiring schematic for a simplified bipolar-field Gramme-ring single-phase–to–direct-current rotary converter. (In actual use, the converter is drum-wound and uses a multipolar field.) [2] Wiring schematic for a simplified two-phase–to–direct-current rotary converter, with the second phase connected at right angles to the first [3] Wiring schematic for a simplified three-phase–to ...
Open-collector output enables one active device to drive the shared line without interference from the other inactive devices. If push–pull output was mistakenly used instead, the active device attempting to set the line voltage low would be in competition with the other devices attempting to set the line voltage high, which would result in ...
One of the two switches must be active (e.g., a transistor), while the other can be a diode. Sometimes, the topology can be changed simply by re-labeling the connections. A 12 V input, 5 V output buck converter can be converted to a 7 V input, −5 V output buck–boost by grounding the output and taking the output from the ground pin.
An electric arc furnace (EAF) is a furnace that heats material by means of an electric arc. Industrial arc furnaces range in size from small units of approximately one-tonne capacity (used in foundries for producing cast iron products) up to about 400-tonne units used for secondary steelmaking.
