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.

cold stuff
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.
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.
What will happen when a cold material interacts with a hot material?
The heat will transfer from the hot material to the cold material. Heat tends to go where it is not.
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.
How much the temperature of a material is changed by heat energy depends?
It depends on the amount of material (its mass), on how much heat energy is added, and on the material's heat capacity.
Effect of temperature on specific heat of material?
The effect of temperature on specific heat of material is referred to as specific heat capacity.
Would material absorb more heat?
If there was more heat to absorb than was already in the material.
Can you explain the transfer of heat within a material?
The transfer of heat within a material, I don't know about. But I can help you with the transfer of heat from one material to another. Heat always moves from the warmer material to the colder one. It does this until it reaches equilibrium. this means when both objects have the same amount of heat energy.
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.
Are BLAST searches able to provide unambiguous identifications?
No.
What is the Heat of vaporization turns a liquid to a gas?
The heat of vaporization is the amount of Thermal Energy (e.g., calories/gram) that must be added to make a material at its boiling point turn into vapor. This number of calories per gram is different for every material.
