Large grinding ring3m forgingsIn order to ensure quality, quality inspection is required for metal forgings, and the inspection has shortcomings.Large grinding ring3m forgingsAccording to the use requirements, inspection standards and the degree of shortcomings to determine its qualified, scrapped, after repair to use. The shortcomings of forgings are distinguished by the process in which they are produced. Forging plant can be divided into: the shortcomings of the raw material production process, the shortcomings of the forging process and the shortcomings of the heat treatment process;Large grinding ring3m forgingsAccording to the order of the various processes in the forging process, the defects generated in the forging process can also be subdivided into the following categories: the defects generated by the blanking, the defects generated by the heating, the defects generated by the forging, the defects generated by the cooling and the defects generated by the cleaning, etc. Different processes can produce different forms of disadvantages. However, the shortcomings of the same form can also come from different processes, because the reasons for the shortcomings of forgings are often related to the raw material production process and the post-forging heat treatment process. The following is a simple introduction for everyoneLarge grinding ring3m forgingsCauses and methods of heat treatment.

Right.Large grinding ring3m forgingsHeat treatment processing, forging heat treatment and improve the mechanical properties of forgings, enhance the use of forgings. So...Large grinding ring3m forgingsThe methods of heat treatment are:

1The forgings shall be laid flat and stable during heat treatment to prevent deformation;

2When stacking, pay attention to the placing sequence to facilitate quenching and lifting of forgings;

3,Large grinding ring3m forgingsIn the heat treatment, can meet the requirements of the case of heating temperature as far as possible to take the lower limit, reduce the quenching intensity;

4On the basis of ensuring the performance of forgings, the medium with low quenching intensity shall be selected as much as possible;

5,Large grinding ring3m forgingsDuring quenching, the quenching medium shall be erected vertically;

62. Temper the forgings in time, and the tempering time shall be long enough for sufficient tempering;

7,Large grinding ring3m forgingsAfter tempering, the deformation reaches the technical requirements.
