What are the regulations for grinding tools in the processing of steel castings
With the continuous acceleration of modernization, the demand for mechanical equipment commodity market is becoming increasingly high, driving the development trend of steel castings. Steel castings are parts produced by processing and manufacturing steel castings, which are key applications in the production and manufacturing of mechanical equipment products. We know that certain production processes need to be mastered during processing. So, what are the regulations for grinding tools in the processing of steel castings?
1. Mold temperature. Steel casting grinding tools need to be heated to a certain temperature before production and manufacturing. Otherwise, when the high-temperature metal material is filled with liquid, it will cause rapid cooling, which will expand the temperature field on the inner surface of the steel casting grinding tool, generate welding stress, and cause the surface of the grinding tool to crack.
2. Filling. In the production and manufacturing of steel castings, it is concluded that metal material liquid filling at high pressure and high speed will inevitably cause violent impact and flushing on steel casting abrasives, thus causing crustal stress and welding stress of mechanical equipment. During the entire impact process of steel castings, the metal material liquid, residue, and vapor will continue to cause complex oxidation with the surface of the grinding tool, accelerating the formation of corrosion and cracks.
3. Mold out. In the whole process of core pulling and steel casting casting, when the steel casting is deformed, it will also cause crustal stress of mechanical equipment and endanger the processing quality of steel castings.
4. Processing process. During the processing of each steel casting, the heat exchanger between the steel casting grinding tool and the metal material liquid causes regular temperature changes on the surface of the steel casting grinding tool, resulting in regular thermal deformation and contraction, resulting in regular welding stress. When this kind of alternating crustal stress constantly circulates, the crustal stress accumulated in the steel casting abrasives becomes larger and larger, leading to cracks in steel castings.
The above are the grinding tool problems that should be paid attention to when producing steel castings. Foundries should pay attention to the hazards caused by the above factors to steel castings during the processing process, and follow appropriate production processes to prevent various difficulties in the production and processing of steel castings and improve the processing quality of steel castings.
