The heat number is an identifying number assigned to the product of one melting in an electric arc furnace. Usually, but not universally: * the first digit indicates the furnace number * the second digit indicates the year in which the heat was melted * the last three (and sometimes four) indicates the melt number. So for example, a heat number 199202 indicates that the product is from the 202nd heat melted in furnance 1 in 1999.

Laser heat treatment in industries?
Lasers can heat ares of a material the same as a flame or an electrical heater. A laser just does it more accurately and more localized with more control. The heat is used to transform "treat" a material. In metals heat can be applied to transform the crystal structure of the material changing its properties. (ie hardness, flexibility) A laser is able to heat a specific area to more tightly controlled temperature for a more tightly controlled time then other means. There for a more known and predictable change in the material can be made. Look up annealing or heat treating on Wikipedia for more information on heat treatment.
Why is plastic foam good at reducing heat loss through walls?
I think it´s becaus the foam is in, principle, a solid with a great quantity of minuscule boubles of air. The heat reducing effect happens thanks to the iar inside the boubles. The material that forms the boubles absorbs a certain amount of heat, and when you apply heat to the exterior, it has to heat the material first then the heat transfer from the material to the air in the bouble. So that effect stacks up subsequently with the next layer of boubles, and the next and so on. Hope I helped you! :-)
Is sheetrock a non-combustible material?
No, it will burn, but needs very high heat to do it.
Can same material with have 2 different heat number?
No, each batch of material should have a unique heat number assigned to it. The heat number is used to trace the specific manufacturing conditions and properties of the material, so having two different heat numbers for the same material would create confusion and potential quality control issues.
What did nazi camp administrators do to identify people from different groups in concentration camps?
One of the identifications was tattooed identifications.
Where are the choke identifications on a 16 gauge cz ringneck?
The choke identifications are on the underside of the barrel. You can see them if you take off the forearm.
Another word for labels?
Identifications
What is heat number?
Heat Number or Cast Number, when refering to metallic component certification, is the identifying number issued to the original cast of a metal from which a component is manufactured. It is normally accompanied by a certificate containing the chemical analysis of the cast material.
What happens to the specific heat of a material if mass is doubled?
There is no change; specific heat is an intensive property of a material, independent of the amount.
Can I buy a number plate identification online?
Well, I would recommend going to your local car insurance company yourself, personally to inquire about the topic of number plate identifications for vehicles.
A measure of the amount of heat in a material?
The measure of the amount of heat in a material is its temperature. Temperature indicates the average kinetic energy of the molecules in a material. The higher the temperature, the more heat energy the material contains.
Are BLAST searches able to provide unambiguous identifications?
No.
How much the temperature of a material is changed by heat energy depends?
The change in temperature of a material due to heat energy depends on the specific heat capacity of the material. Different materials have different specific heat capacities, which determine how much heat energy is needed to raise their temperature by a certain amount.
Would material absorb more heat?
If there was more heat to absorb than was already in the material.
What will happen when a cold material interacts with a hot material?
When a cold material interacts with a hot material, heat will transfer from the hot material to the cold material until they reach thermal equilibrium. This will result in the hot material cooling down and the cold material heating up. The rate of heat transfer will depend on the temperature difference between the two materials and their thermal properties.
