[0002] Rotary kilns can be divided into cement kilns, metallurgical and chemical kilns and lime kilns according to the materials they process.

[0003] Cement kilns are mainly used to calcine cement clinker, which are divided into two categories: dry process cement kilns and wet process cement kilns; metallurgical and chemical kilns are mainly used in the metallurgical industry for magnetization roasting of lean iron ore in steel mills, oxidation roasting of chromium and nickel iron ore, roasting of high-alumina vanadium ore in refractory plants, roasting of clinker and aluminum hydroxide in aluminum plants, and roasting of chromium ore sand and chromium ore powder in chemical plants; lime kilns (i.e. active lime kilns) are used to roast active lime and light-burned dolomite for use in steel mills and ferroalloy plants.

[0004] The kiln head guard plate is installed at the kiln head of the rotary kiln body to seal and prevent leakage of the calcined material feed. At present, the traditional kiln head guard plate is damaged by the wear of the kiln mouth castable after installation (the calcined material feed wears the castable), which causes the castable to fall off in large pieces. This requires regular maintenance and frequent replacement, which increases economic costs. Frequent shutdowns for maintenance also reduce production efficiency. At the same time, there is also leakage at the kiln mouth, resulting in production safety and environmental protection problems.

[0005] Therefore, based on the above problems, the utility model provides a kiln head heat-resistant steel guard plate for a rotary kiln. Utility Model Content
