Analysis of metallic materials

The possibilities for chemical analysis include the characterization and identification of iron-based metal alloys (steels and low alloy resulfurized). This laboratory has all the necessary equipment, and the accreditations and certifications that guarantee traceability.

The main objectives of the Chemical Laboratory are:

  • Maintain and improve the quality of the trials of the chemical analysis of the final product and process samples steelmaking GSW.
  • Assist various industry sectors that somehow kept regarding processes, processing, manufacturing, or commissioning of equipment or components built with steel.
  • To support the technical needs of the various departments GSW.

Quality, independence and responsiveness

The Chemical Laboratory of Global Steel Wire is an independent department with its own autonomous Quality Management System to meet the requirements of ISO / IEC 17025 and meet the needs of both external and internal customers.

All testing services are backed by a System of Quality Management according to UNE-EN-ISO 9001:2008.

Optical Emission Spectrometer Arc / Spark

Team Name: ARL 4460 Manufacturer: THERMO FISHER SCIENTIFIC
Serial No. Manufacturer: 2013
Nº inventory: 033LQAC
Published: December 2013
Current Location: Chemical Laboratory. Analysis room

Foundation: The excitation-emission spectrometry with arc / spark is based on measuring the energy emitted by the excited to return to its ground state atom. Excitation was performed using a high voltage electrical discharge which produces an electric arc between the electrode and the metal sample. The emitted wavelengths are characteristic of each element and are detected by photomultipliers which convert the signal intensity being proportional to the concentration of the elements of the sample.

Sample Type: Metal. Require surface polishing. Reference materials are needed in the base iron.

Applications: Determination of elements in metallic materials. SPARK DAT-application analysis of inclusions.

34 analytical channels

  • Canal nitrogen with argon gas purifier.
  • Analytical Software OXSAS.
  • SPARK-DAT with 32 channels.

Spectrometer XRF

Team Name: ARL 9400 Manufacturer: THERMO FISHER SCIENTIFIC
Manufacturer Serial No: 200
Nº inventory: 026LQAC
Published: May 1999
Current Location: Chemical Laboratory. Analysis room

Foundation: Spectrometry X-ray fluorescence (XRF) spectroscopy is a technique in which the secondary emission of fluorescent radiation or X, generated by the excitation of the sample with a primary X-ray source is used. The energy of the emitted radiation is characteristic of each atomic species. Being the intensity of the emitted radiation according to the concentration of the sample emitting element. Thus it is possible to identify the elements present in the sample by the characteristic signals (qualitative analysis) and to correlate the intensity of emitted radiation and the concentration of the element studied.

Sample Type: All kind of samples:

  • Metal: sanding or polishing required as calibration standards.
  • No metal.
  • Pearls by fusion with lithium tetraborate sample for analysis of major elements.
  • Sample pressed pellets with microcrystalline cellulose for analysis of ferroalloys.

Applications: Determination of elements in metallic and nonmetallic materials in solid sample.

  • 26 analytic channels.
  • Analytic Software OXSAS.

Elemental carbon and sulfur analyzer

Team Name: CS 200 Manufacturer: LECO INSTRUMENTOS
Nº inventory: 006LQAC
Published: January 1999
Current Location: Chemical Laboratory. Analysis room

Foundation: Induction furnace combustion and IR absorption detection. The analytical procedure for determining the content of total sulfur and carbon in metallic samples, especially of iron base, and inorganic materials, by using an infrared absorption method after solid-state combustion of the sample in an oven induction.

The sample is introduced in a ceramic crucible, an accelerator is added and the material is placed in the charging stand. The conductive elements of the sample and the accelerator is inductively coupled with the high frequency field generated by the furnace, and combustion occurs in a stream of oxygen.

Carbon in the sample is mainly oxidised to CO2, small amounts of CO may occur, and sulfur is similarly SO2.

The flue gases generated to measure the S as SO2 in the first cell and infrared C as CO2 in the second cell of IR.

Sample Type: Metal, railroad signs, and non-ferrous (slag, etc..). Cylindrical shaped pins, rings, chips or powder, with nominal sample size of 1 g.

Applications: Determination of carbon and sulfur, metallic and inorganic materials.

Published: Febrero 2003
Current location: Chemical Laboratory. Analysis room

Foundation: Melting under an inert gas and O detection (IR absorption) and N (thermal conductivity).

Fusion under inert gas (helium) is used to determine quantitative content of gases, oxygen and nitrogen, ferrous base metal samples and non-ferrous.

Fusion under inert gas (helium) is used to determine quantitative content of gases, oxygen and nitrogen, based ferrous metal and non-ferrous samples.

The sample is placed in a graphite crucible of a single use, which is placed on the furnace bottom electrode. The door is closed and the melting of the sample occurs. Simultaneously, the total content of O and N of the sample is determined. Nitrogen and oxygen are extracted in the form of CO and N 2 (molecular nitrogen), respectively, which are transported to the detection system for helium gas. The CO is oxidized to CO2 and is selectively measured in a cell of IR. The N2 is measured by thermal conductivity.

Sample type: Metal, ferrous and non-ferrous samples. Cylindrical shaped pins, chip or dust.

Applications: Determination of oxygen and nitrogen, metal and non-metallic.
