In the sand making machine production and processing in the heat treatment process are:
(1 ) Quenching: heating means or steel to Ac3 Ac1 ( the critical temperature of the steel ) above a certain temperature for a certain time , then an appropriate cooling rate , martensite ( or bainite ) tissue the heat treatment process. Common salt bath quenching process has hardened , martensitic quenching , Austempering , surface hardening and partial quenching. Quenching purpose: to make the steel needed to obtain martensite improve Crusher hardness, strength and wear resistance, heat treatment , after prepare for the organization and preparation .
( 2 ) Tempering: the workpiece is hardened and tempered heated to a temperature below the AC1 , holding a certain time and then cooled to room temperature in the heat treatment process . Common tempering process are: tempering , tempering , tempering and multiple tempering .
The purpose of tempering : steel mainly to eliminate stress produced during quenching , the steel having high hardness and wear resistance , but also has the required plasticity and toughness .
( 3 ) Annealing : refers to the metal material is heated to a suitable temperature , for a certain time , and then slowly cooling the heat treatment process . Common annealing process are: recrystallization annealing, stress relieving , ball annealing , fully annealed and so on. The purpose of annealing : mainly to reduce the hardness of the metal material , to improve the plasticity , or cutting processing to Liqie pressure processing , reduce the residual stress and improve the uniformity of microstructure and composition , heat treatment , after possible or tissue preparation.
( 4 ) normalizing : the workpiece is heated to above Ac3 or Accm 30 ~ 50 ℃, holding time after removal from the furnace in air or water , or hair spray cooled metal heat treatment process. The purpose of normalizing : mainly to improve the mechanical properties of low carbon steel to improve machinability , grain refinement , elimination of tissue defects, prepare for the heat treatment , after tissue preparation.
( 5 ) carburization : carburizing is instructed to process the carbon atoms into the steel surface layer. Also the low- carbon steel having a high carbon steel workpiece surface layer , and then after quenching and tempering , the surface layer of the workpiece having a high hardness and wear resistance, while the central portion of the workpiece remains in the low-carbon steel and ductile plasticity.
( 6 ) quenched : refers to the quenching and tempering of steel or composite steel heat treatment process .Crusher Used in quenching said steel quenched and tempered steel . It generally refers to the carbon structure of carbon steel and alloy steel .
