Today, the boiler accessories manufacturer will share with you the reasons for the failure of Anti Oxidation Scaly Chain Boiler Grates, and the material requirements are not high. In order to reduce the cost, HT200 is mostly used for the sealing iron on the grate side, and its low heat-resisting temperature will easily cause high-temperature burning and deformation of the chain. Due to the high temperature in the furnace of Anti Oxidation Scaly Chain Boiler Grates, it is suitable to use heat-resistant cast iron. Such as RQTA122, the heat-resistant temperature can reach 1100 ℃ in the air furnace gas. The main chain of the grate should also be made of heat-resistant cast iron to ensure long-term good mechanical properties.
Anti Oxidation Scaly Chain Boiler Grates do not require high manufacturing precision and have large errors. As a quick-loading boiler, the flatness of the front and rear shafts of the grate affects the resistance of the grate and the average degree of stress, which is easy to cause the grate to deviate and break. When the Anti Oxidation Scaly Chain Boiler Grates is deviated, there is no reference mark for adjusting the bolts on both sides. Based on experience alone, it will cause inconvenience to users. The tooling error of the grate's active sprockets is large, causing the sprockets to wear and tear, and the grate is torn due to uneven force. , Arching, grate shaft bending.
Anti Oxidation Scaly Chain Boiler Grates throttle air volume control is rough. Due to the baking of the grate, the temperature at the air door is generally around 100°C. Affected by expansion and contraction, the parts are easily deformed, resulting in failures such as lax closing and inconsistency with the actual opening.
