Description
Technical Field
The invention relates to the technical field of metal material performance detection, in particular to a system and a method for preparing dendrite detection samples by sanding and grinding.
Background
In ferrous metallurgy and equipment manufacturing industry, enterprises need to perform low-power inspection on casting blanks and rolling and forging finished products according to national standards, smelting standards, national army standards or international general standards, and the like, and finally determine the flow direction of inspected products by grading defects such as detected cracks, shrinkage cavities, segregation and the like. Traditional low-power inspection modes widely used in the field comprise sulfur seal, hot acid, cold acid and electrolytic corrosion, and advanced enterprises aim at high-end steel inclined research and development in numerous subdivision fields along with the implementation of national high-quality development strategy. However, the quality characteristics of high-end steel products cannot be accurately reflected according to defect grading characterization such as cracks, shrinkage cavities, segregation and the like, and the quality characteristics such as marked homogeneity, fine crystals, compactness and the like need to be expressed through a plurality of morphological characteristics of solidification structures and residual as-cast solidification structures, including the types, distribution, refinement degree and the like of dendrites. While it can only present blurred as-cast coagulated tissue images with a small probability or not at all using conventional low-power inspection techniques.
Dendrite inspection is a new generation low-power inspection technology which appears in the beginning of the century, is mainly aimed at the difficult defect detection of common steel continuous casting blanks in the early stage, and has another advantage in recent years, namely, the dendrite inspection technology can clearly detect the details of solidification structures of the steel continuous casting blanks, so that the dendrite inspection technology becomes an indispensable means for high-end steel quality control and new product research and development. In the dendrite inspection system, a dendrite sanding grinder is one of key equipment, but the dendrite surface corrosion quality of a dendrite inspection sample prepared by the existing dendrite inspection sample preparation system is unstable, so that the clear imaging effect of dendrite is affected, and the quality of steel cannot be reflected stably by the detection result.
Disclosure of Invention

How to work with high quality of dendrite sanding grinding machines is a major concern, and the inventor finds that: the sanding and grinding water distribution control is a core process of the dendrite sanding and grinding machine, is an important factor that dendrite corrosion can be clearly imaged, and the dendrite surface corrosion quality can be affected due to improper water distribution pressure of the dendrite sanding and grinding machine, so that the dendrite can be clearly imaged. In the prior art, a manual water distribution control method is generally adopted in the dendrite sanding water distribution control method, an operator adjusts the grinding water distribution pressure through a hand valve and a mechanical scale pressure gauge in the conventional dendrite sanding grinding process, and the operator reads the pressure value of the mechanical scale pressure gauge first and then manually adjusts the hand valve according to the water pressure value required by the grinding process. The manual control method has simple control principle and simple operation, but the control method has obvious defects: the error of the mechanical scale pressure gauge is larger, the error of the pressure value read by different operators at different angles is larger, and the dendrite sanding grinding process is finally influenced; when an operator manually adjusts the hand valve, the water pressure is difficult to accurately adjust to the most suitable water pressure, and the manual adjustment error is large; when the pressure of the water inlet pressure is stable, the manual water distribution control method of the dendrite sander is relatively stable, but when the water inlet pressure is unstable or changes due to external reasons, the manual water distribution control method cannot be dynamically adjusted, and finally the quality of the grinding process is influenced due to the unstable water pressure of the sander, so that the imaging effect of dendrite corrosion is influenced.
