What is a foundry ladle made of?
Foundry ladles usually comprise of a mild steel shell with a refractory lining material. Effectively it is the refractory lining material that allows the foundry ladle to be used with molten metal whilst the steel shell provides support for the refractory. Traditionally the refractory material used to be firebrick, fireclay or even rammed sand. However it is more common for foundries to now use special refractory concretes that have high insulation values and last longer. Examples can be seen at www.acetarc.co.uk Where small amounts of metal are to be cast foundries will sometimes use ceramic crucibles to hold the metal.
Differences between afbc and cfbc boilers?
(fbc) boiler to heat the Water that is mixed with a refractory material. With warming water temperatures will produce refractory materials that will ignite the oil in the water. The granular refractory materials are mixed with water. Refractory materials are heated in water to take it. c) boiler column. The steam comes out vertically. A) horizontal boiler. The steam comes out horizontally.
How does the threshold voltage change during the relative refractory period?
The threshold may increase until a certain point in which the refractory period is so short that it will not allow for stimulus. Toby G Attending EMT-P school.
Who invented insulation?
The person that invented insulation was John Player. This was the standard type of insulation, and it was invented by him in 1893.
What is difference between insulation resistance test and polarization index?
Insulation resistance test: This test is used to find the insulation resistance of motor for 1 min or 10 min through high voltage insulation tester. By this we can find the insulation level. Polarization index: This is the ratio between insulation resistance for 10 min to insulation resistance for 1 min.
What do you mean by refractory concrete?
refractory Concrete means refractory castable == ==
Why did Yilong Refractory change their name into Changxing Refractory?
Because of Changxing Refractory's largest investment, Yilong Refractory was renamed as Changxing Refractrory.

How is the mineral xonotlite used?
Xonotlite is used as a component in high-temperature insulation materials, especially in applications that require resistance to heat, chemicals, and high pressure. It is also utilized in the manufacturing of refractory products, such as furnace linings and insulation boards, due to its thermal properties.
How do you use refractory in a sentence?
1) The virus was refractory to the medication. 2) The refractory class was unable to get anything done.
Where you can get refractory concrete?

What is mag-dolo refractory?
magnesium-dolomite based refractory
Will the refractory product quality and services also change as the name of Yilong Refractory changed into Changxing Refractory?
The only change of Yilong Refractory is its name which has changed into Changxing Refractory. Its product quality, pre-sale and after-sale services remain unchanged.
What is the relationship between the relative refractory period and the absolute refractory period in terms of neuronal excitability?
The relative refractory period is the time when a neuron can respond to a stronger stimulus, while the absolute refractory period is when a neuron cannot respond at all. The relative refractory period follows the absolute refractory period and allows for increased neuronal excitability.
What is the difference between the refractory period and the absolute refractory period in terms of neuronal signaling?
The refractory period is the time after a neuron fires when it cannot fire again, while the absolute refractory period is the specific part of the refractory period when the neuron is completely unable to fire, regardless of the stimulus.
What are the best materials for stove insulation to ensure safety and efficiency?
The best materials for stove insulation to ensure safety and efficiency are ceramic fiber, vermiculite, and refractory cement. These materials can withstand high temperatures and help retain heat, making the stove more efficient and reducing the risk of fire hazards.
2 Define refractory period and differentiate between absolute and relative refractory periods?
refractory period is the interval between action potential , the absolute refractory period is the period in which second action potential can not be initiated but in relative refractory period the second action potential can be initiated by the more strong stimulus.
