Cast iron products is to meet the requirements as terms of delivery with mechanical propertys such as its tensile strength.Tensile strength be material by the critical value of uniform plastic deformation to concentration of local plastic yield transition, also be the maximum load-carrying capacity of material under quiet stretching condition.The tensile strength of cast iron materials experiment at present is that coupon is unpacked, just accomplished on the testing machine in the laboratory after the ball blast sand removal, cut through supercooling.By the time when issuing the tensile strength laboratory report, cast iron products casts already.If therefore can in melting, foresee the tensile strength of cast iron materials, so just can before cast, molten steel quality be adjusted to the state that tensile strength meets terms of delivery, this point is the detection means that manufacturer presses for grasp.
The device of on-line prediction cast iron materials tensile strength all is to use molten steel quality thermal analyzer or spectrometer separately at present.Because the molten steel quality thermal analyzer only uses the phase change characteristics parameter of solidified molten pig iron to predict the precision of Tensile strength, so precision of prediction is low, and this precision related coefficient of comparing with the data that coupon is surveyed on testing machine is merely 0.6-0.7.Though some molten steel quality thermal analyzer has adopted the method for input alloy content in detection; But the data comparison related coefficient of surveying on tensile strength precision that dopes and the testing machine also fails to surpass 0.8; This is to comprise three big key elements such as chemical analysis, cooling velocity, core amounts because of the factor that influences cast iron materials tensile strength, and the chemical constitution of using when the phase change characteristics parameter that adopts when therefore using the molten steel quality thermal analyzer is merely perhaps used spectrometer merely comes the tensile strength of on-line prediction cast iron materials all to exist certain defective and deficiency.
Summary of the invention
In order to address the above problem, the purpose of the utility model is the cast iron tensile strength on-line prediction system that provides a kind of precision of prediction high.
In order to achieve the above object, the cast iron tensile strength on-line prediction system that provides of the utility model comprises molten steel quality thermal analyzer, spectrometer and radio transmission system; Wherein: the molten steel quality thermal analyzer links to each other with sample cup for thermal analysis through compensating wire, the phase change characteristics parameter when being used to measure tested molten steel solidification in the sample cup for thermal analysis; Spectrometer is used to analyze the component content of the air chill test piece of being processed by tested molten iron; Radio transmission system comprises radio transmitting module and radio reception module, and wherein radio transmitting module is connected on the USB or com port of PC on the spectrometer through connecting line, is used for the detected component content measurement result of spectrometer is outwards sent; The radio reception module is connected on the com port of principal computer on the molten steel quality thermal analyzer through connecting line; Be used to receive the component content measurement result that the radio transmitting module is sent; Carry out data processing then; And give the radio transmitting module sending the return signal of receiving data after the assay was approved, it is said that simultaneously passing number is given the principal computer of molten steel quality thermal analyzer.
Described radio transmitting module is installed on the spectrometer, and the radio reception module is installed on the molten steel quality thermal analyzer.
The cast iron tensile strength on-line prediction system that the utility model provides is that to utilize radio transmission system that molten steel quality thermal analyzer and spectrometer are organically combined be a system; It can combine the measurement result of molten steel quality thermal analyzer and spectrometer; Because its testing result has comprised the three big key elements that influence cast iron materials tensile strength; So the precision of the cast iron materials tensile strength that on-line prediction goes out all is higher than molten steel quality thermal analyzer or spectrometer predicting the outcome separately, and with testing machine on the data of surveying relatively related coefficient can be up to more than 0.95.In addition; Use native system manufacturer can before molten iron pouring, can obtain the tensile strength of cast iron materials; Therefore can fundamentally eliminate the generation of casting wasted product, thus can be energy-conservation, reduce discharging and improve the utilization factor of resource, thereby have huge economic and social benefit.
