In the research, the quenching medium is water. The mass, momentum and energy equations of gas-liquid two-phase of quenching medium and the quenching heat conduction equation of stainless steel workpiece are solved by numerical simulation. Based on the principle of equal heat flux between quenching medium and workpiece, the temperature field of quenching medium and workpiece is solved by coupling. The comparison between the numerical simulation and experimental results of decorative stainless steel pipe shows that the numerical simulation results of workpiece temperature are in good agreement with the experimental data. The model can reliably simulate the quenching process of workpiece, and can be extended to the multiphase flow simulation in complex system to guide the actual production. The single pass thermal simulation compression experiment of Cr super martensitic stainless steel was carried out by Gleeble thermal simulation tester to study the thermal deformation behavior at ~ ℃ and strain rate of . ~ s-, and the microstructure evolution law of grains under different conditions was analyzed; Based on Sellars hyperbolic sinusoidal model, the flow stress constitutive equation of Cr super martensitic stainless steel was constructed. The results show that the peak stress decreases with the increase of deformation temperature and the decrease of strain rate; With the increase of deformation temperature, the grain grows and coarsens gradually. With the increase of strain rate, the dynamic recrystallized grains are obviously refined. The thermal deformation activation energy Q = . JMOL of decorative stainless steel pipe is calculated, and the expression of Zener Hollomon parameter is obtained. Different feedstocks were prepared by mixing crmnmon nickel free austenitic stainless steel powder prepared by aerosol and wax based binder. The effects of binder ratio and powder loading on the rheological properties of feed were studied by rh high pressure capillary rheometer. Non Newtonian index n, viscous flow activation energy E and comprehensive rheological factor alpha are calculated by second order model regression analysis; STV.

The binder system was composed of % microcrystalline wax (MW), % high density polyethylene (HDPE), % ethylene vinyl acetate copolymer (EVA) and % stearic acid (SA). The powder loading was vol%. The feed had good comprehensive rheological properties. In order to study the cementitious properties of stainless steel AOD slag, stainless steel AOD slag was used to replace some cement, and its effects on the working properties and mechanical properties of cement mortar were studied. The results show that using stainless steel AOD slag to replace cement from ~ %, with the increase of the content of stainless steel AOD slag, the water consumption of standard consistency of cement first decreases and then increases. When the content is %, the water reduction effect of stainless steel AOD slag is good; With the increase of the content of stainless steel AOD slag, the strength of cement mortar decreases in turn, indicating that the cementitious activity of stainless steel AOD slag is small.safety requirements ,For example,Otrokovice304dq stainless steel plate, the price of tons of goods = tons = the result example: the price excluding tax of ton of goods = a ton = ~ the total weight of the known coil weight and price = the coil weight price, the thickness of stainless steel plate & Chi; Width & Chi; Long & Chi; e.g. & Chi; Χ Χ = kg stainless steel plate weight per square meter (kg) calculation formula: specific gravity thickness (mm) width (mm) length (m) stainless steel weight per meter (kg) stainless steel pipe calculation formula: diameter (mm) diameter (mm) (correct calculation of the price difference between burr and trimming of nickel stainless steel . chromium stainless steel) in the market, the price difference between burr and trimming of stainless steel is usually set at a fixed price. For example, it is generally considered in the market that the price difference between burr and trimming of is yuan tons and that of is yuan tons. In fact, the price difference between burr and trimming of stainless steel is different The correct calculation should be like this.Adjust the ratio of austenite forming elements to ferrite forming elements in the steel to make it have austenite + ferrite dual phase structure, in which ferrite accounts for % - %. This dual phase structure is not easy to produce intergranular corrosion.Corrosion resistance of decorative stainless steel pipe the price of different series of stainless steel materials varies greatly. The corrosion resistance of more economical materials can not meet the higher application requirements, and the improvement of corrosion resistance of stainless steel materials by simple chemical passivation is limited. On the other hand, the traditional passivation treatment containing chromium salt has been gradually eliminated, and the passivation treatment of stainless steel has turned to the direction of environmental friendliness. Recently, citric acid passivation and silicon treatment on stainless steel surface have become a new research direction. The former has environmental protection characteristics because its passivation solution component does not contain chromium salt. The latter has found that silicon coupling agent is chemically adsorbed on the metal surface to form a protective silicon film with cross-linked network structure. The length of discoloration time of samples after different surface treatments was compared by blue dot method, the corrosion rate of samples after different surface treatments was distinguished by brine immersion test, and the salt spray resistance of samples after different surface treatments was distinguished by neutral salt spray test, The differences of pitting corrosion resistance and resistance to corrosive medium of samples after different surface treatment were compared by electrochemical test. The film thickness of silicon film was indirectly characterized by film weight test and scanning electron microscope, energy spectrometer, X-ray diffraction X-ray photoelectron spectroscopy and total reflection Fourier transform infrared spectroscopy characterized the surface films of different surface treated samples, and analyzed the structural composition and corrosion resistance mechanism of different films. Professional stainless steel plate, stainless steel coil, stainless steel belt, high price, service, honest management! At present, there are few studies on the combination of citric acid passivation and silicon treatment of stainless steel. Therefore, this paper studies the difference of corrosion resistance of martensitic stainless steel Cr chemical passivation, silicon treatment and the combination of citric acid passivation and acid silicon system treatment, and discusses the corrosion resistance mechanism of different films on its surface, which can provide reference for the new direction of stainless steel surface treatment, It has certain practical guiding significance. The corrosion resistance and mechanism of chemical passivation, silicon treatment and composite treatment of martensitic stainless steel were studied in this paper. The comprehensive comparison of the research results shows that the corrosion resistance of stainless steel treated with different surface treatments is different. The corrosion resistance of the sample treated with silicon alone is better than that treated with traditional dichromate passivation. The corrosion resistance of the composite treated sample treated with citric acid passivation and acid silicon system is further enhanced than that treated with acid silicon system alone. The composite treatment of citric acid passivation and acid silicon system treatment has excellent corrosion resistance and environmental protection characteristics, and is expected to replace the traditional dichromate passivation treatment. According to the film weight test results, the surface silicon film weight of the composite treated sample after citric acid passivation and acid silicon system treatment is lower than that of the sample after acid silicon system treatment alone, indicating that the excellent corrosion resistance of the composite film not only depends on the surface silicon film, but also benefits from its double-layer film structure.
