In a stone crushing plant, other than jaw breaker and feeder machine, there is still a crucial machine that is needed, which is VSI sand maker, short for sand maker. To perfectly crush stone materials into sand particles, sand making machinery cannot go without the technology for heating processing.
The technologies for heating processing of sand maker include tempering, hardening and tempering, anneal, normalizing and quenching. When seeing these words, every customer will feel strange and do not their meanings. Here Henan Fote Heavy Machinery Co., Ltd. will give a detailed introduction.
Tempering refers to the thermal treatment of heating the steel materials which are hardened to a certain temperature and cooling them to indoor temperature after keeping warm for a period of time. Hardening and tempering refers to the multiplex heat treatment of carrying out quenching and high-temperature tempering on the steel materials. Anneal refers to the thermal treatment of heating the metal materials to a proper temperature and slowly cooling them down after keeping warm for a period of time. Normalizing refers to the thermal treatment of heating the steel materials to over upper critical point of steel and cooling them in steel air after keeping a certain normal temperature. Quenching refers to the thermal treatment of heating the steel materials to a certain temperature of over Ac3 or Ac1 and gaining martensitic structure with proper cooling speed after keeping it for a period of time in a certain temperature.
These are the knowledge points about the technologies for heating processing of sand maker.
