How nut coke is charged in blast furnace?
According to steel.nic.in; Coke Rate is measured in Kgs of BF Coke consumed per tonne of Hot Metal produced in the Blast Furnace(Kg/THM). By convention, this excludes coke (nut/pearl coke) mixed with sinter etc.
Introduction of high quality coke to a blast furnace will result in lower coke rate, higher productivity and lower hot metal cost. This principal is followed by many private chemical firms like Coke Oven Consultants and so on.
IEEE stands for Institute of Electrical and Electronics Engineers. It is an organization made up of engineers, scientists and students who develop standards for the computer and electronics industry.
What do you understand by regulation in a transformer?
Regulation of transformer means percentage reduction of transformer secondary voltage due to transformer loading as compared to its no load voltage.
Another AnswerA transformer's voltage regulation is defined as 'the change in its secondary voltage, from no-load to full-load, at a specified power factor, expressed as a percentage of its full-load voltage, with the primary supply voltage held constant'.What is the silver content of plumbing solder?
That would depend on the application just like tin and lead solder or tin and antimony.
There are so called silver solders which is a wrong term as solder normally pertains to a lead content .
It should be technically called a silver bearing alloy as per AWS specifications
Depending on the tensile strength that one would want such as brazing alloys where we have joints 87,000 or low temperature silver bearing which has an average tensile strength of 16,000
Open cast mining is mines that are dug on hilly areas. It is quick easy way of providing coal but it damages the wildlife and can be quite dangerous. The way open cast mining is carried out is that they stay on the same ground level when digging. This is done by moving the dug out soil along so slowly more area has been dug out. This will continue until all the coal has been removed and then the mine will be filled up again and left to grow naturally.
When was the Chrysler building built?
From 1928 to 1930.
Construction was started Sept. 19, 1928 and completed on May 28, 1930
An old method of reproducing drawings that wound up with the copies being blue background with the lines in white. The original drawing was fed through rollers with the blank paper that exposed it to light. Then the blank paper was devleoped by exposing it amonia---very smelly process. The paper would develope into a blue color and the exposed lines were white---usually.
What type of tools does an engineer use?
There are a wide variety of types of tools. These include drills, hammers, screw drivers, wrenches, saws, as well as axes.
How can you melt fused silica?
Fused silica has 2 meanings: previously fused silica and presently fused silica.
Previously fused silica is fused by heating it to its melting point. This can be done in crucible in a furnace.
Presently fused silica is already hot and fused.
Note: melted silica is probably a conductor, at least melted glass is a conductor.
Container used to transport molten metal in a foundry?
Ladle
While a ladle is used in the process, I believe the container being asking about is either the slag pot or the smelting pot.
I agree the call ladle because our customer from foundry plant also call ladle.we produce the ladle transfer car according to the customer demand.The ladle widely use in the steel industry.
How do you calculate actual power factor?
The power factor of a circuit is defined as the cosine of the phase angle -which is the angle by which the supply current lags or leads the supply voltage in AC circuits.
Power factor is always expressed as either a 'lagging power factor' or as a 'leading power factor'.
The terms 'lagging' or 'leading' describe the relationship of the supply current to the supply voltage. Since current lags voltage in an inductive circuit, 'lagging power factors' describe inductive circuits; since current leads voltage in capacitive circuits, 'leading power factors' describe capacitive circuits. In practice, lagging power factors are more common than leading power factors, because most practical loads are inductive (e.g. motors, etc.).
Power factors are normally expressed as a decimal (e.g. '0.8 lagging') although, in the past they were often expressed as a percentage (e.g. '80% lagging'). 'High' power factors tend towards unity, whereas 'low' power factors tend towards zero.
In terms of power, the cosine of a circuit's phase angle and, therefore, its power factor is the ratio of that circuit's true power (expressed in watts) and its apparent power (expressed in volt amperes).
Power factor has no effect whatsoever upon the energy consumed by a load, but it does effect the amount of current drawn from the supply. 'Low' power factors result in unnecessarily-large load currents for any given load, which mean that the supply utilities need to use larger than necessary conductor sizes (expensive!). For industrial or commercial (but not residential) loads, therefore, it is often desirable to 'improve' the load's power factor towards unity, which acts to reduce the load current. This is most-usually done by installing capacitors close to the load, and is termed 'power-factor correction' or 'power-factor improvement'. Capacitors used in this way are rated in reactive volt amperes, rather than in microfarads.

What is absolute expansion of steam turbine?
it's the thermal expansion in the casing of hp or ip turbine
can be noticed by journal or thrust bearing when moving <<
Write an example for thermosetting plastic and thermo plastic?
Thermoplastics can be repeatedly softened by heating and hardened by cooling. Thermosetting plastics, however, harden permanently after being heated once.
An example of thermoplastic is polypropylene (PP - recycling number 5).
An example of thermosetting plastic is polyurathane (PU).
Who was the second person to break the sound barrier?
The second person to break the sound barrier was Clarence "Chuck" Manning. He was my great-grandfather; he fought in three wars and played professional basketball for Alabama.
What is Difference between mild steel and high yield strength deformed steel?
Mild steel (grade A36) has a minimum yield of 36,000 psi. A572 grade 50 has a minimum yield of 50,000 psi.
What is the colour code of diesel pipe line as per NFPA standard?
As per Indian standard its Brown colour.
--------------------------------------------------------------------------------
There is no specific code for coding pipelines in the US, different industrial plants use different color schemes. Gray pipe with a dashed red stripe painted every 6 feet, yellow pipe with a solid red stripe every 6 feet, solid orange pipe (solid red pipe is always fire protection systems according to NFPA rules), brown pipe with red or black stripes every 6 feet....and so on.
What are instrumentation cables?
Instrumentation cables are not generic. Instrumentation cables are wires that allow for a signal to be put into one end and give the same signal at the other end without distortion. What that means is if the instrument has a resisitive sensing element the 'instrument cable' used would have a very low resistive value and protection from enviromential influence to the cable to not change the value. Instrumentation cable may also be used for powering a device - which once again if powered via regulated voltage you'll want to make sure the voltage given at one end is the same on the other end. Instrumentation cables are also used for high frequency measurements are made. These instrument cables will have a frequency limitation typically based on the length of cable used due to its capacitance.
What is the difference between intermittent and continuous production processes?
An intermittent process is something that goes on and off a bit any old how, w/o any obvious rhythm to it. A continuous process is something that just runs and runs.
How is the density of steel st 37?

How Caclulate ms chequered plate weight with chart?
Size of sheet is mentioned in length , width [either in millimeters(mm) or meters(m)]
and thickness in millimeters(mm)
Base Density of Aluminum - 2710 kg/cubic meter
For 6 mm thickness of sheet for dimensions length - 2438mm width -1219mm
Weight of sheet is calculated as follows -
-Convert length and width dimensions of mm into meters
2438/1000 = 2.438m and 1219/1000 = 1.219m and 6.3/1000 = .0063m
- Area per sheet - 2.438 x 1.219 = 2.97 sq.m
- Weight = Area x thickness x density = 2.97 x .0063 x 2710 = 50.7 kgs approx.
