Description

Comprehensive simulation experiment platform and method suitable for rapid treatment and zinc plating
Technical Field
The invention relates to a research and development technology of continuous heat treatment, in particular to a comprehensive simulation experiment platform suitable for rapid treatment and zinc plating and a method thereof.
Background
With the worsening of the environment and the increasing shortage of energy, the technology of saving energy and reducing emission by lightening the weight of automobiles becomes the trend of the current automobile industry, and the development of new materials with high performance becomes a hot point of research, so as to improve the efficiency of experiments, save energy and reduce cost, and the researches are more and more focused on.
In industrial production, the return of the strip steel is divided into cover annealing and continuous annealing, and compared with the cover annealing process, the continuous annealing process can greatly save the annealing time and reduce the energy consumption, thereby reducing the production cost and obtaining better mechanical property. However, the conventional continuous annealing process mainly adopts radiation and convection heat transfer, the maximum heating rate is only 100 ℃/s, the whole continuous annealing process still takes about ten minutes, and the types of samples subjected to heat treatment are limited. And the traditional continuous annealing process is relatively complex in equipment, long in production line, large in occupied space, and easy to cause a series of problems of nodulation, floating bending, high energy consumption, large thermal inertia and the like in the annealing process. In recent years, a transverse magnetic induction annealing method is proposed, the heating rate can be increased to 1000 ℃/s, the purposes of rapid heating, short-time heat preservation or no heat preservation and then rapid cooling can be achieved, the rapid annealing process can greatly shorten the continuous annealing time, reduce the energy consumption and finally reduce the production cost, a more compact production line is allowed to be used, the space is saved, and the microstructure and the performance of the material can be controlled better.
However, in industrial production, strip steel not only needs to be subjected to a heat treatment process, but also needs to be subjected to subsequent treatment such as hot-dip plating or alloying and the like to meet the use requirement, but simulation experiment equipment in the world is not enough to meet the requirement at present, a GLLEBLE thermal simulation experiment machine has the defects that the size of a sample capable of being subjected to an experiment is too small, the industrial reference value is not large, an IWATANI hot-dip galvanizing simulation experiment machine also has the defects that the size of the sample is too different from the actual industrial requirement, the heating and cooling rates are not enough to meet the requirement, and other simulation devices such as a bright annealing simulation device have too low cooling rate and do not have the hot-dip galvanizing. These devices also do not have the function of a reduction annealing atmosphere furnace and cannot meet the simulation requirements in industrial experiments.
In the existing patent application, for example, the chinese patent of application No. 200810010124.2 discloses a cold-rolled strip steel continuous annealing simulation experiment machine, which comprises an experiment machine body, a sample heating device, a sample cooling device, a tension mechanism, a gas discharge system and a vacuum system, and is characterized in that the experiment machine body consists of a machine base, a furnace cover, a furnace body, a trolley and a trolley driving mechanism, the trolley driving mechanism adopts a guide rail slide block kinematic pair, the sample cooling device is installed on the inner wall of the furnace body, a water diversion pipe and a gas diversion pipe of the sample cooling device are welded on a cooling nozzle mounting flange opening, the end part of the furnace body is provided with a vacuumizing opening, a nitrogen emergency purging opening and a protective atmosphere inlet, the furnace body is also provided with a pressure sensor interface and is provided with a pressure sensor, the tension oil cylinder and a rigid frame are both installed on a central installation base of the furnace cover, a cylinder rod of the tension oil cylinder is, the two heating electrodes and the clamping mechanism are respectively fixed on the right tripod and the sliding plate. The device has the characteristics of complete functions, simple structure, convenient and safe operation, low cost and the like, but does not have the simulation functions of galvanizing and alloying.
Also, as the chinese patent application No. 201010100939.7, a laboratory simulation apparatus and method for a galvanizing line alloying process is disclosed, the apparatus includes an air pressure system, an air pressure regulator, a cooler, a thermocouple, a sample, a driving device, an infrared heating furnace, an electromagnetic induction furnace, a two-color infrared thermometer, and a driving motor, the method adopts a temperature measurement and control mode combining the thermocouple temperature measurement and the two-color infrared thermometer, and simultaneously performs temperature measurement and control on the sample in the electromagnetic induction furnace, thereby avoiding the influence of an electromagnetic field on the temperature measurement precision. The method has the advantages that the technological parameters of the systems such as the electromagnetic induction heating furnace, the infrared heating furnace, the cooler, the driving device and the like are controlled to be consistent with the production line process, so that the Zn-Fe diffusion process of the alloying of the galvanizing production line is accurately simulated, the influence of different alloying technological parameters on eta, zeta, 1 and other coating tissues is accurately judged, the control is flexible, the experimental result is accurate, and the production debugging cost is reduced. However, the device of the invention adopts electromagnetic induction to alloy the coating, and can not realize the simulation experiment of rapid thermal treatment of the substrate.
