Description
Technical field
The utility model relates to iron ore performance index determinator, especially belongs to the determinator to the softening situation of iron ore performance.
Background technology
At present, the determinator of the softening situation of iron ore, its structure mostly is greatly: it is open that heating element adopts the lower end of Si-Mo rod, body of heater, like this bore pipe in body of heater be about penetration.So because unreasonable structure, have the following disadvantages: power consumption is big, the chimney effect heat waste is big, the measurement result precision is not high, big etc. for artificial supervision, heating gradient to the mensuration process of the softening situation of ore.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, provide that a kind of power consumption is little, high insulating effect, the measurement result precision is high and stable, the mensuration process of the softening situation of ore is realized robotization, the iron ore softening furnace determinator that heating gradient is little.
Realize the technical measures of above-mentioned purpose: iron ore softening furnace determinator, comprise stove, be contained in the bore pipe in the body of heater respectively, heat-insulation layer, crucible, thermocouple, the balancing weight that the depression bar upper end is provided with, displacement meter, connecting rod, it is that the lower surface of the body of heater of stainless steel is what seal, be wound with iron chrome molybdenum heating filament on the bore pipe, heat-insulation layer is the hollow aluminum ball, connecting rod is connected with depression bar by graphite bush, thermocouple is contained in depression bar and the connecting rod, sensor type is counted in displacement, and be connected with stop on being connected connecting rod, stop is connected on the support of fixing with body of heater, and computing machine is by lead and thermocouple, displacement meter connects respectively.
It is that connecting rod is rotating.
It is to be equipped with stove silk support member in body of heater.
Principle of work:
At first tested sample is crushed to 1～2mm, sample is put into crucible, work loading height to 20～25mm, crucible is enclosed within the bottom of depression bar, 90 ° of rotation depression bars make depression bar aim at the center of heating furnace burner hearth again, put down depression bar to burner hearth of the furnace body, cover the top cover plate of body of heater, loading is mixed.Open computing machine, input sample title and numbering.Heating furnace begins heating, and at this moment, computing machine is read the charge level height, and as zero point of displacement.Heating furnace carries out the sample heating according to fixed heating gradient.When displacement meter begins to rise and rises to temperature when the highest is expand beginning and finishing temperature of sample.When displacement meter rises to peak and the shift length that begins to descend is the sample expansion distance.When sample begins to expand and shrinks, computing machine can be taken into account thermocouple from displacement and read corresponding readings, and calculates softening properties automatically.
Advantage of the present utility model is that compact conformation, power consumption are little, high insulating effect, the measurement result precision is high and stable, the mensuration process of the softening situation of ore is realized robotization, make the softening furnace intensification realize the segmentation control of speed, and make whole softening process curve more clear, little, the long service life of heating gradient.
