Utility model works process:
The quick molten iron analyser in the utility model stokehold in the course of the work, when detecting cast iron composition, get molten iron when molten steel quality is carried out thermal analyses and pour into sample cup, under the specific radiating condition of sample cup, first thermal analyzer records the temperature of solidification curve of molten iron in sample cup, by the parsing to temperature of solidification curve, find out the various phase change characteristics parameters of molten steel solidification process, after bringing phase change characteristics parameter value into set up with solidified structure mathematical model, namely can calculate the important controling parameters determining molten steel solidification tissue.The corresponding relation being solidified as example explanation temperature of solidification curve and phasor with air chill molten iron: get base iron and pour into the sample cup being added with and forcing air chill composition, thermal analyzer have recorded the temperature of solidification curve of air chill molten iron in sample cup.First platform of temperature of solidification curve is molten iron when cooling to liquidus curve, the solid-phase release latent heat of generation, and maintain sample cup and to fall apart thermogenetic temperature platform, this platform temperature is called liquidus temperature (TL) by us.What molten iron carried out subsequently is selective freezing process, and the latent heat discharged in selective freezing is not enough to the heat radiation maintaining sample cup, and temperature curve is slow downward trend.When the remaining molten iron of selective freezing arrives eutectic composition, start eutectic freezing.Residue molten iron discharges a large amount of latent heats in eutectic freezing, until all molten iron solidifies completely, maintains a longer temperature platform.We claim this temperature platform to be eutectic temperature (TE).We are by measuring the temperature of solidification curve of molten iron, just can capture phase transition temperature eigenwert, active ingredient content in phase transition temperature value and molten iron or specific solidified structure are set up mathematical relation, the active ingredient content corresponding with phase transition temperature or specific solidified structure can be calculated.
Acticarbon equivalent is a very important parameter, and it decides molten iron and with what kind of organizational form starts to solidify.Thermal analyses can measure the acticarbon equivalent (in molten iron, the combined action result of all graphitizations, anti-graphitization composition and carbon, is different from the calculating carbon equivalent of CE=C+Si/3) of molten iron.
If CE is too low, liquidus temperature increases.The high overtemperature of molten iron that causes of liquidus temperature reduces, and the mobility of molten iron reduces, and the risk that cold shut defects occurs increases.Liquidus temperature is higher, and the speed of solidifying cooling is larger, and the risk producing spoken parts in traditional operas defect is larger.The results such as CE is too low also causes primary austenite too much, and the risk of shrinkage cavity increases, and makes the tensile strength of gray iron too high, and the graphite of magnesium iron and compacted iron is very few.
If CE is too high, can causes that primary austenite is very few, graphite is too much, the result that the tensile strength of gray iron reduces.When CE is higher than eutectic composition, solidify from graphitization is floating, the mobility of molten iron reduces, and also can cause the generation of cold shut defects.The floating meeting of graphitization causes carbon content during eutectic freezing to reduce, and graphitization expansion is few, so the shrinkage porosite risk of hypereutectic molten iron is larger.
Based on such steering logic, by input acquisition module 19, the information collected is sent to microprocessor 22, corresponding informance is sent to display module 23 and printer 24 by microprocessor 22, optimum configurations and the duty of microprocessor can be changed by keyboard 21, display module 23 can represent following content: the data such as date, time, liquidus temperature, eutectic temperature, CE value, C%, Si%, with the cooling curve of image display CE.Can arrange multiple calibration curve by keyboard 23, and mutually switch, set melting order according to multiple target materials, and be arranged respectively to a point parameter, the response time is short, and precision is high, good stability, and structure is simple, perfect in shape and function.
Above-described embodiment is to explanation of the present utility model, is not to restriction of the present utility model, anyly all belongs to protection domain of the present utility model to the scheme after the utility model simple transformation.
