Principles for determining preparatory processing: Generally, structural steel parts are quenched and tempered. The high temperature tempering temperature should be 20~40 °C higher than the nitriding temperature, and the holding time should not be too long. For parts with low impact toughness ......
Read MoreCementation: The workpiece after cementation is quenched and tempered at low temperature, so that the surface has high hardness and wear resistance, while the core still maintains good plasticity and toughness, so as to meet the requirements of the workpiece to be hard on the outside and tough......
Read More1. Product introduction: Strong convection bell annealing furnaces are used for bright annealing of cold rolled strips. The strong convection hood type annealing furnace is composed of a solid annealing furnace table and the supply medium input/output pipes below it, a protective cover, an ele......
Read MoreDetermination of process specifications: 1. Nitriding temperature 1) Commonly used at 500~530℃, it can ensure that the nitride has a larger dispersion and the highest hardness 2) As the nitriding temperature increases, the depth of the nitriding layer increases, while the hardness decreases si......

Equipment application: This series of gas trolley heat treatment furnaces are periodic operation furnaces, which are suitable for heat treatment of materials such as tungsten and molybdenum products and various chemical products. 2. Equipment composition: The gas trolley heat treatment furn......
Read MoreIn the process of rolling (mostly cold rolling) of silicon steel sheet, its internal crystal arrangement is regular. For example, the crystal arrangement of the H-series non-oriented sheet is disordered, and the Z-series oriented sheet crystals are ordered in one direction. During the process ......
