What is difference between Cupola furnace and blast furnace?
In essence nothing, a Cupola furnace is a type of blast furnace in that it is charged at the top and tapped at the bottom and air is blasted into the furnace via a wind belt and tuyres.
A blast furnace in a steel works is a huge structure operated for long periods of time, it is charged with iron ore, coke and limestone and reduces the iron ore into pure iron.
A Cupola furnace, as used in the foundry re melts pig iron, from the blast furnace, along with foundry scrap, steel scrap and scrap iron engine blocks and produced iron alloys of various specifications. A Cupola furnace is usually operated on a daily basis but some types can be continuously operated for several weeks
How are step up and step down transformers used in the transmission of elecricity?
Step up transformers are used to increase voltage.
Step down transformers are used to decrease voltage, these are the most common. The can on the power pole is a step down, a doorbell also uses a step down transformer.

How pass line is calculated in hot rolling mill?
Rolling schedule is the time sequence of passes of rolled piece through the mill respecting many constrains and limitations such as:
- * Limit separating force
- * Limit rolling torque
- * Bite angle
- * Flatness limits
- * Metallurgical limits
- * Specific limits(length of delay table, etc.)
If all constrains are fulfilled and rolling schedule gives maximum productivity (minimum production time) and the desired product and its specifications are obtained, we can speak about optimum rolling schedule.
What is the percentage of carbon in dead mild steel?
Carbon content in dead mild steel is betweet 0.05% & 0.15% .
Does mild steel resist corrosion?
The corrosion rate of a metal is a function of many factors like:
-fluid to which the metal is exposed (chemical composition, concentration..)
-temperature
-flow velocity
-time of exposure
so it's not possibile to give a simple answer
Difference between step up and step down transformers?
Actually an isolation transformer may be physically the same as a Step up/Step Down transformer. The main difference is in the way they are used.
Another difference is that in a normal transformer there will be capacitance between the 2 windings, between the windings and core, between the core and shell, etc. These capacitances bring in high frequency noise from outside, which will be transmitted in the secondary circuit. So [in an isolation transformer] wires are connected between each component, (not direct contact, but with insulation present). This permits a leakage current and eliminates unnecessary capacitance. I could make a start to answer this question. Isolation transformer: is a transformer with two separate windings, the primary and the secondary. There is an electrical isolation between the primary and the secondary. Nearly any type of transformer with two non-connected windings could be considered an "isolation" transformer, in that it electrically isolates the primary voltage from the secondary voltage. There are also transformers with one winding (called auto-transformers) and connections for input and output. If the input is low voltage and the output a higher, then you can say it is a STEP-UP transformer. If the input is high and the output is low, then you can say it is a STEP-DOWN. This type of transformer can not by used where safety is a large factor.

How did the internal combustion engine change America?
With the use of steam power, factories could be built near natural resources and where the work force was. Factories started to grow all over England and then spread to the rest of the world. Cities became more populated because the factories offered a lot of jobs. Work in the factory was more reliable than work in the fields due to the fact that farming was dependent on the weather and crops often failed. The steam engine could now make machines in the factories produce materials much faster. By the early 1800's there were hundreds of steampowered machines in the factories. Steam ran the machines in textile mills and other types offactories. In the 1820's lighter and simpler steam engines were made that could be used in small mills and stores and not just large factories.

What is the job of a groyne at the beach?
A groyne is a structure which is built at least partially underwater to inhibit water flow and control the movement of sediment. The purpose of a groin at the beach is either to create more beach or to prevent the erosion of an existing beach.
What is the color code for water lines?
Pipes containing potable (drinkable) water will be colored dark blue. Those carrying settled or clarified water will be colored Agua (lightish blue). Pipes containing raw water (not for drinking) will be colored olive green.
What is the difference between a weldolet and a sockolet?
Weldolet and Sockolet are basically self reinforced fittings. Weldolet is used for Butt weld branch connection where standard tee is not available due to size restrictions and the piping is of critical / high pressure service. Sockolet is used for socket welding branch connection, which require reinforcing pad.
What is interposing voltage transformer?
Interphase transformers are utilized as a part of frameworks that have two rectifier frameworks being utilized as a part of parallel. The requirement for the Interphase Transformer is available in light of the fact that when associating rectifiers in parallel, their immediate voltages vary.
Can step down transformer be used as a step up transformer?
If the transformer has two separate windings, then, YES a step-down can be used as a step-up, and vice-versa.
It is more correct to say you are reversing the high and low sides.
By definition Primary is the "IN" side and Secondary is the "OUT" side.
The Primary could be the high voltage side if it is a step-down,
or it could be the low voltage side, if it is a step-up.
Care must be taken when reversing the operation of a step-down transformer to insure that it does not exceed the ratings of the transformer. For example, let's say we have a 12 VA step-down transformer that takes 120Vac in and is rated to provide 12V at 1 amp at the secondary. If we were to reverse it and apply 12Vac to the new primary (the old secondary), we would have 120Vac at the new secondary, but to keep within the original ratings it could only be loaded to 0.1A @ 120Vac.
As long as you treat the output rating of the step-down transformer as the input rating as a step-up transformer, and don't try to draw current beyond what would normally have been applied to the high voltage primary, you should be fine. Potentially one could push up the voltage on such a transformer beyond what its stated application specified, while making sure not to exceed the power rating of the transformer and not exceeding the breakdown voltage of the transformer's insulation, for example driving the above transformer at 24V to get 0.05A @ 240Vac. It is important to realize though that the rated input voltage for a step-down transformer will likely not be a safe input voltage if you use it as a step-up transformer - for example, applying 120V to the above transformer with the windings reversed would generate 1.2KV!
One important point to remember when reversing a three-phase transformer to a step-up is what kind of windings it has. Most three-phase transformers use a "delta" configuration on the primary side. This means that there are three "hot wires" and a ground, but not a neutral. (The white wire in a circuit). On the secondary side, transformers are usually wired up in a "Wye" (sometimes called a "star" configuration. Doing this allows the transformer to create a Neutral connection. If a step-down transformer is reversed to make it a step-up, the high (output) side will not have a Neutral connection. If one is not needed, say for a three-phase welding machine, this would not be a probem. However, if a Neutral IS needed ,say for lighting, reversing this transformer would not work. In this case, a listed step-up transformer will be needed. One final thing, if a step-down transformer is used as a step-up, a Neutral wire is not required to be connected to the input side.
Pearlite is a layered steel product made from ferrite (iron) and cementite (iron carbide). Pearlite is stronger and lighter than regular steel, but is more prone to cracking.
What do you mean by turbine synchronization?
During a typical power plant startup, all components of the power plant are started slowly. The turbine is first rolled at a slow rpm. Then the rpm is increased gradually to a point where it can match the frequency of the grid. At this point, the turbine can be synchronized with the grid and start outputting electricity into the grid.
What are active and passive transducers?
An example of a passive transducer is differential transformers. The reason why is because passive transducers require an external power supply to operate.
