Embodiment 1

[0046] The preparation method of the particle tracer of the present embodiment comprises the following steps:

[0047] (1) Weighing M 1 The known polystyrene plastic particles of g are placed in a water bath and heated to 100°C for 10 minutes. After the particles become larger and float to the water surface, they are collected and dried; the polystyrene plastic particles obtained after heating in a water bath The diameter is 1-2mm, the density ρ of the collected polystyrene plastic particles 1 =0.143g / cm 3 .

[0048] (2) Weighing M 2 g of red paraffin, heated and melted in a ceramic crucible for 1-2 minutes;

[0049] (3) Pour the treated polystyrene plastic particles into a crucible for storing paraffin, and stir until evenly mixed;

[0050] (4) Pour the mixture of polystyrene plastic particles and paraffin wax into warm water at 40-42°C, and stir for 1 minute. The mixture is evenly dispersed on the water surface, and the above mixture is directly kneaded into the same sh...

Embodiment 2

[0053] The production method of the particle tracer in this embodiment is basically the same as in Embodiment 1, the difference is that the density of the inclusion model to be simulated in this embodiment is 0.7g / cm 3 , then the mass of polystyrene plastic particles M 1 with paraffin mass M 2 Satisfy the following relationship: i.e. M 1 :M 2 = 0.05.

Abstract

The invention discloses a particle tracer for simulating inclusions in molten steel as well as a preparation method and application of the particle tracer, and belongs to the technical field of preparation of particle tracers. The invention discloses the particle tracer for simulating inclusions in molten steel. The tracer is prepared by mixing polystyrene plastic particles and red paraffin, and the ratio of the mass M1 of the polystyrene plastic particles to the mass M2 of the paraffin meets the following relational expression: the polystyrene plastic particles heated in a water bath and themolten paraffin are uniformly mixed and then put into warm water to be stirred, and then the mixture can be kneaded into the particle tracer with required shape, density and size. The tracer preparedby the method provided by the invention can more accurately simulate flow behaviors of inclusions, and the method can be used for preparing particle tracers with different densities, thereby meeting requirements of different physical model experiments.

Description

technical field [0001] The invention belongs to the technical field of particle tracer production, and more specifically relates to a particle tracer for simulating inclusions in molten steel and a production method thereof. Background technique [0002] With the advancement of modern technology and the development of modern industry, the quality requirements of steel are getting higher and higher. The existence of inclusions (mainly oxide inclusions) in steel will seriously affect the quality of steel. With the concept of clean steel and pure steel The proposal of the standard puts forward more stringent requirements for the control of inclusions in steel. The inclusions in the steel can reduce the plasticity, toughness and fatigue life of the steel, make the processing performance of the steel worse, and also have a direct impact on the surface finish and welding performance of the steel. Therefore, it is of great significance to study the behavior of inclusions in steel....
