Nitrogen roller hearth furnace
It is used for heat treatment process of lithium iron phosphate lithium positive electrode material.
1、Index parameter
Rated temperature: 700-1200 degrees centigrade
Maximum temperature: 1200 degrees centigrade
Sintering atmosphere: nitrogen gas
Heating element: heating wire / silicon carbide rod
Heating element layout: up and down heating
Effective height: 150mm/200mm/250mm/300mm
The total height of the equipment: < 2100mm
2、Progressiveness
1. High accuracy: the temperature difference in effective section is less than 10 C (+ 5 C), and the material consistency is high.
2, large capacity: six single tier, annual output of a single unit can reach more than 1300 tons (different processes will be different).
3. High sealing property: the heating chamber and the transmission bin are sealed independently, and the structure of the import and export sealed gate ensures the oxygen content less than 10ppm.
4, the atmosphere system: the left middle and right preheating intake, can adjust the intake volume independently, reduce the influence on the temperature field; closed loop control exhaust system, effectively ensure the exhaust effect, maintain the furnace pressure stable, effectively ensure the stability of the product.
5, the transmission is stable and reliable: the specially designed roll rod coupling, combined with the roll bar installation technology, effectively ensures the steady operation of the casket, and eliminates the phenomenon of running deviation and card furnace.
6. German import control system: distributed embedded control system based on Ethernet communication, with powerful function and high precision temperature control module, realizing intelligent control and building large database, including all process parameters, energy consumption, equipment state, fully digitized display and recording, for the establishment of intelligent chemical plant Full control system remainder;
7, the unique cooling water jacket design, effectively guarantee the cooling efficiency, and ensure the discharging temperature is less than 60 degrees.
(Ps expert's message: about 20% of the heat energy is dissipated by the end of the roller. To this end, the atmosphere roller hearth furnace on both sides of the heating rod sealing cavity and transmission seal cavity, all installed with air inlet nozzle, direct air blowing cooling roll rod ends, and the air of the seal cavity pressure from the installation hole pressure into the furnace, on the one hand the atmosphere is preheated, on the other hand, due to positive pressure, effectively prevent the rod hole heat dissipation! At the bottom of the heating section and the constant temperature section, a number of small holes are opened in the bottom of the insulation layer. The atmosphere is divided into the middle and right of the furnace at the bottom of the furnace, and the air volume is adjustable in the direction of the width of the 3 way. )
