Technical principle:
When some oxides are heated and have gas phase conditions, oxygen atoms will combine with hydrogen atoms to cause redox reactions,and the oxides will be deoxvgenated to generate elemental materials; some salt substances are heated at different heatinq temperatures Decomposition reaction occurs under calcination to generate oxides or multi-phase materials; the steel strip loaded materials reciprocate in a heating device filled with air or other gases to produce these materials in large quantities.
Equipment overview:
The main mechanism is composed of feeding section, heatin section,slow Cooling section,Cooling section and disCharge section, protective atmosphere control system,water cooling system, electrical control system, etc. The charging section includes the charging table, the inlet muffle tube, and the charging table is equipped with a small loading car that can move left and right with the steel belt to ensure that the materials are evenly arranged on the steel belt. The muffle tube in the heating section is made into a corruaated shape. WwnICn inCreases the strenath of the mutle,(ompared with the ordinarv muffle tube the serYice lite Is extended by more than 1.5 times.I he inlet and outlet of the materlal adopt roller seal or adoptf 0as Clirtain + tiber curtain seal which has aood sealing performance and low air consumption.The material conveving svstem consists of driving steel belts,It consists of a transmission device and a multi-stage tensioning device. The running speed of the steel belt is steplessly adjusted by a frequency converter, and it can be equipped with an automatic correction device for the steel belt. The temperature control system is composed of thermocouple,imported digital display intelligent PID requlator and thyristor, forming a closed loop control system to realize automatic and precise temperature control.
Mainly used for oxide deoxidation and reduction in the powder industry to produce iron powder, copper powder, cobalt powder, nickel powder, molybdenum powder, tungsten powder and other metal powders;drying and Calcination of Cobalt oxalate,APT, and carbonates to generate corresponding oxides.
