Description
Technical field:
The utility model relates to sintering checkout equipment technical field, particularly relates to the original material device for checking air permeability of a kind of sintering.
Background technology:
In the prior art, the gas penetration potential sintering original material is most important to sintering process.Current experimental provision used mostly is measuring cup or circular measuring tank, and owing to differing comparatively large with on-the-spot hopper shape, too small draught area, makes gas edge effect (as gas backstreaming, eddy flow etc.) cause measurement error larger; The change of environment temperature, pressure also causes error to detection of gas flow rate.The test figure that current various document provides is discrete and can not simulate and reproduce, and makes production scene cannot obtain the original material permeability index of reliable and stable sintering, directly affects the control of production technology.
Summary of the invention:
The purpose of this utility model overcomes the deficiency that prior art exists, provide a kind of sinter original material permeability measurement value and actual value error less, the one that measuring accuracy is higher sinters original material device for checking air permeability.
Technical solution of the present utility model is to provide the original material device for checking air permeability of a kind of sintering, comprises air machinery, reduction valve, variable valve a, variable valve b, pressure unit a, temperature transmitter, pressure unit b, air chamber, panel board; It is characterized in that: also comprise metal tube flowmeter, hopper; Air machinery is connected with reduction valve; Reduction valve is connected with variable valve a, b; The air chamber UNICOM of hopper and its underpart; The pipeline that air chamber is connected with air machinery is provided with metal tube flowmeter; Pressure unit a, pressure unit b and temperature transmitter is connected with between this pipeline and panel board.Be further characterized in that: hopper is the square tube shape of widening surface of contact, by the general hopper equal proportion design of steel mill.
Implementation result of the present utility model is: by the air flow rate of gas circuit modification stability by hopper, error effect factor is produced in effective elimination flow detection, and this flow is scaled mark condition flow through temperature and pressure compensation, measure hopper air inlet/outlet pressure reduction simultaneously, utilize internationally recognized computing formula to calculate permeability index, ensure holding water and obtaining the authentic and valid of data of the method for sampling; To obtain different material high for data by experiment, and empirical data value under the correlation parameter such as different flow, different operating modes, for application data base set up by different quality, dissimilar original material; And set up real time data modification method, thus obtain effective feedforward control in real time, eliminate the impact that system is delayed.Adopt the barrel-shaped hopper scheme in side of widening surface of contact, by the general hopper equal proportion design of steel mill, the edge effect occurred in can effectively avoiding lab setup to detect causes data misalignment.Thus provide accurate empirical data to support for practical application.The permeability measurement value and the actual value error that make to sinter original material are little, and measuring accuracy is higher.
