Optimum configuration of special corundum flexible slag-resistant bricks in zinc oxide rotary kilns

Optimum configuration of special corundum flexible slag-resistant bricks in zinc oxide rotary kilns
Optimum configuration of special corundum flexible slag-resistant bricks in zinc oxide rotary kilns

Current conventional configuration (producing ceramic-grade zinc oxide powder from iron-water slag)

  • Low-cement steel-fibre castable
  • Phosphate wear-resistant brick — service life ≥300 days
  • High-RUL phosphate brick — service life ≥75 days
  • Low-cement steel-fibre castable

Recommended optimised configuration

  • Low-cement steel-fibre castable
  • Anti-spalling wear-resistant brick + corundum flexible slag brick, rotary-laid — target service life ≥720 days
  • ① High-RUL phosphate brick — target ≥300 days ② High-RUL phosphate brick + low-conductivity corundum flexible slag-resistant brick, rotary-laid — target ≥300 days
  • ① JX low-conductivity corundum flexible slag-resistant brick — target ≥300 days ② Magnesia-alumina-chrome spinel brick — target ≥180 days
  • Low-cement steel-fibre castable

Note: the actual configuration is set separately according to the properties of the customer's raw materials; rotary masonry gives the best results.

Zinc oxide rotary kiln — conventional vs recommended configuration (service life, days)

Low-temperature reaction zone

High-temperature reaction zone

An alternative with magnesia-alumina-chrome spinel brick has a target service life of ≥180 days.
