The cross bar is one of the key components of the cross bar grate cooler. The cross bar is a key component of the grate cooler, which is used to push the clinker forward and play the role of conveying clinker. During the clinker conveying and cooling process, the cross bar is constantly in contact with the high-temperature clinker and bears the impact and friction of the clinker, so it needs to have high wear resistance.
The shape is cross-shaped. This shape design enables the cross bar to stir, shear and convey the clinker more effectively in the process of pushing the clinker, so that the clinker is fully exposed to the cooling air and improves the cooling efficiency. The cross bar usually has certain size specifications, and the specific size will vary according to the model and design requirements of the grate cooler. Its size design needs to take into account factors such as the clinker conveying volume, the internal space of the grate cooler, and the coordination with other components.
It is generally made of wear-resistant, high-temperature resistant and high-strength alloy materials. For example, some cross bar materials require a chromium (Cr) content of not less than 24%, a nickel (Ni) content of more than 20%, etc., and undergo a special heat treatment process to improve hardness and toughness. Some manufacturers will perform special treatment on the surface of the cross bar, such as surfacing a wear-resistant layer to further enhance its wear resistance. This can ensure that the cross bar has good performance and a long service life in a high-temperature, high-wear working environment. Ensure long-term stable operation in harsh working environments.
The cross bar is installed on the grate bed of the grate cooler through a specific connection method, and the firmness and accuracy of the installation must be ensured to ensure that the cross bar can work properly. Some cross bar connection shells are installed on the grate cooler through a detachable fixed connection method such as a top tightening structure, which is convenient for installation and disassembly.
