Abstract

Methods and systems for managing a heating process are disclosed. An example method can comprise removing a first portion of a material from a vessel and measuring a first parameter of a second portion of the material in the vessel. The second portion of the material can remain in the vessel after the removal of the first portion. The method can comprise, determining a volume of the second portion of the material based on the first parameter, updating a second parameter based on the volume, and performing a process based on the updated second parameter.

First claim

What is claimed is:

1 . A method comprising:
removing a first portion of a material from a vessel; measuring a first parameter of a second portion of the material in the vessel, wherein the second portion of the material remains in the vessel after the removal of the first portion; determining a volume of the second portion of the material based on the first parameter; updating a second parameter based on the volume; and performing a process based on the updated second parameter.

2 . The method of claim 1 , wherein the volume of the second portion of the material is determined based on an assumption that the volume is shaped as a partial sphere.

3 . The method of claim 1 , further comprising determining a mass of the second portion of the material based on the volume, wherein the second parameter is updated based on the mass of the second portion of the material.

4 . The method of claim 1 , wherein the second parameter comprises at least one of an amount of additional material to provide to the vessel, an amount of energy to provide in the vessel, a temperature to bring the material to in the vessel, an amount of additives to provide to the vessel, and an amount of time to perform a heating process in the vessel.

5 . The method of claim 4 , wherein performing the process comprises at least one of providing the additional material to the vessel, providing the energy to the vessel, bringing the material in the vessel to the temperature, providing the additives to the vessel, and performing a heating process.

6 . The method of claim 1 , wherein the second portion of the material comprises a steel hot heel and the vessel comprises a steel making vessel.

7 . The method of claim 1 , wherein the first parameter comprises at least one of a height of the second portion of the material, a size of the second portion of the material, and a shape of the second portion of the material.

8 . The method of claim 1 , wherein the vessel comprises a part of an Electric Arc Furnace.

9 . The method of claim 1 , wherein the process comprises a metal making process, and wherein performing the process comprises providing additional material to the vessel, and wherein the amount of the additional material is determined based on the second parameter.

10 . The method of claim 9 , wherein the metal making process comprises a steel making process.

11 . The method of claim 2 , further comprising determining a mass of the second portion of the material based on the volume, wherein the second parameter is updated based on the mass of the second portion of the material.

12 . The method of claim 2 , wherein the second parameter comprises at least one of an amount of additional material to provide to the vessel, an amount of energy to provide in the vessel, a temperature to bring the material to in the vessel, an amount of additives to provide to the vessel, and an amount of time to perform a heating process in the vessel.

13 . The method of claim 12 , wherein performing the process comprises at least one of providing the additional material to the vessel, providing the energy to the vessel, bringing the material in the vessel to the temperature, providing the additives to the vessel, and performing a heating process.

14 . The method of claim 2 , wherein the second portion of the material comprises a steel hot heel and the vessel comprises a steel making vessel.

15 . The method of claim 2 , wherein the second portion of the material comprises a steel hot heel and the vessel comprises a steel making vessel.

16 . The method of claim 2 , wherein the first parameter comprises at least one of a height of the second portion of the material, a size of the second portion of the material, and a shape of the second portion of the material.

17 . The method of claim 2 , wherein the vessel comprises a part of an Electric Arc Furnace.

18 . The method of claim 2 , wherein the process comprises a metal making process, and wherein performing the process comprises providing additional material to the vessel, and wherein the amount of the additional material is determined based on the second parameter.

19 . The method of claim 3 , wherein the second portion of the material comprises a steel hot heel and the vessel comprises a steel making vessel.

20 . The method of claim 3 , wherein the second portion of the material comprises a steel hot heel and the vessel comprises a steel making vessel.
