Mass - spectrometer system FTIAN-5

System FTIAN-5 is intended for the continuous control of structure of departing gases over various conditions of metallurgical manufacture (converter and domain processes: pumping out or autogenously smelting, manufacture of especially pure metals, etc.). Thus with the help of system it is supervised not only structure of a gas phase, but in some cases temperature of melt and the contents of the basic component in melt.
Structure of system comprises:
  • Mass – spectrometer of time of flight type;
  • The device for sampling and preparation of samples;
  • Independent system of water cooling.
CHARACTERISTICS
Resolution 500
Quantity of determined components of a mix of gases up to 16
Time of the analysis, sec 0,04-2
Range of measured concentration, % (about). 10-7 -100
Registered value of nitrogen in oxygen of blasting, % (about). 0,01
Full error of the analysis of departing gases (the converter, a blast furnace, the vacuum gauge), including Н2, CO, CO2, N2, O2, Ag (for one second of the analysis), % 0,1
Error of the analysis of an impurity in technical oxygen of blasting (N2, Аg) at concentration N2 and Аg less than 0,1 % volumetric, % (about). 0,002
Error of definition of temperature of steel on a course of process, not more, oС 10
Presence of the device for sampling and preparation of samples there is
Presence of independent system of water cooling there is

The resulted parameters of purpose are achieved by the new structural organization of the analyzer and all device as a whole which is characterized by the following features:
  • Presence of separate evacuation of electron gun,
  • Presence of the channel for ion counting.
  • Application in the channel of an analog signal broadband current amplifier of spectral pulses.
Essential difference of the analyzer of new mass - spectrometer system is application in it of the device of selective suppression of intensive peaks. It allows to receive the big dynamic range of measurement of the device and considerably to increase service life of the receiver of ions. The resource of work of an electron gun essentially increases due to its separate evacuation.
Operational reliability of new mass - spectrometer system is raised due to application of the independent device of water cooling and two thermoelectric traps of a new design.

APPLICATION OF FTIAN SYSTEMS IN METALLURGY

Systems FTIAN are intended for the decision is industrial - the analytical problems arising by manufacture of steel, pig-iron and nonferrous metals.
It is essential, that the information can be received without a stop of technological process.
The primary goals solved with the help of systems of series FTIAN:
  • The current control of temperature of steel (nonferrous metals) over time swimming trunks without a stop of process, including the continuous control over a required range of temperatures (for steel: 1550-1750 oС).
  • Error of definition of temperature ±10 oC.
  • Definition of the current contents of carbon in steel without a stop of melting. An error of definition + -0,015 % at the contents of carbon in melt not more than 0,2 %.
  • Definition of the current contents of sulfur on a course of melting in manufacturing of nonferrous metals and steel.
  • Definition of cleanness of the gases used in manufacture. For example, among such problems it is possible to specify exact continuous definition of impurity in oxygen of blasting, argon of blasting, methane.
  • The analysis of structure of the gas environment and departing gases in various metallurgical manufactures (including: converter process, domain process, pumping out). Controllable components: Н2, N2, O2, CO, CO2, SO2, H2 S, Н2 O, СН4, NO, NO2, Аr and other inert gases, other gas components.
