If the previous 6 articles respectively progressed from identifying wear types, the effects of temperature, material sticking and flow blockage, to wear-location mapping and the chain of operational consequences, this section addresses the corrective roadmap based on the actual condition of each location<\/strong>.<\/p>\n

The general sequence consists of three steps: identify the mechanism \u2192 measure the actual conditions \u2192 select the material group<\/strong>. Correctly identifying the mechanism indicates what needs to be checked; field measurements indicate the severity of the action; only then is there sufficient basis to evaluate material options.<\/p>\n

1. The next step depends on the condition of the location<\/span><\/h2>\n

Not every case needs to begin with a full survey. The first step is to determine where the plant currently stands in the diagnostic process.<\/p>\n

1.1. When there is a clearly damaged location<\/span><\/h3>\n

If the equipment currently has a deteriorating location, the starting point is to observe directly at the damaged area<\/strong>, not the name of the existing material or the material being considered as a replacement.<\/p>\n

The sequence can be carried out as follows:<\/p>\n\n\n\n\n\n\n\n\n
Step<\/strong><\/th>\nActivity to be performed<\/strong><\/th>\nArticle to review<\/strong><\/th>\n<\/tr>\n<\/thead>\n
1<\/strong><\/td>\nIdentify the area deteriorating most rapidly<\/td>\nPart 1: 4 types of wear and their identifying signs on the surface<\/strong><\/span><\/a><\/td>\n<\/tr>\n
2<\/strong><\/td>\nInterpret the shape and orientation of the damage marks and compare them with the material-flow direction<\/td>\nPart 1: 4 types of wear and their identifying signs on the surface<\/strong><\/span><\/a><\/td>\n<\/tr>\n
3<\/strong><\/td>\nRecord operating temperature, peak temperature, and temperature-fluctuation conditions<\/td>\nPart 2: Effects of temperature on the operating limits of materials<\/strong><\/span><\/a><\/td>\n<\/tr>\n
4<\/strong><\/td>\nDistinguish whether the damage lies in the surface, material build-up layer, or fastening location<\/td>\nPart 1<\/strong> <\/span><\/a>and Part 3: Material sticking and flow blockage: formation mechanisms and identifying signs<\/strong><\/span><\/a><\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

The final step is particularly important. If the actual cause lies in the fastening point or material-flow geometry, replacing the lining with a new one may still result in repeated failure even if the material itself is suitable for the wear conditions.<\/p>\n

1.2. When the material has already been replaced but the location continues to fail repeatedly<\/span><\/h3>\n

A lack of service-life improvement after replacing the lining is not sufficient to conclude that the new material is still \u201cnot good enough.\u201d<\/p>\n

Before changing to another option, two possibilities need to be rechecked:<\/p>\n\n\n\n\n\n\n
Possibility to be checked<\/strong><\/th>\nIndication<\/strong><\/th>\nFurther reading direction<\/strong><\/th>\n<\/tr>\n<\/thead>\n
Incorrect identification of the wear mechanism<\/strong><\/td>\nThe actual damage patterns do not match the assumed mechanism<\/td>\nPart 1: 4 types of wear and their identifying signs on the surface<\/span><\/strong><\/a><\/td>\n<\/tr>\n
The cause is not wear-related<\/strong><\/td>\nMaterial builds up on the surface, the flow becomes blocked, or damage is concentrated at the fastening location<\/td>\nPart 3: Material sticking and flow blockage: formation mechanisms and identifying signs<\/strong><\/a><\/span> or recheck the fastening point<\/td>\n<\/tr>\n<\/tbody>\n<\/table>\n

If material is building up on the wall, the problem shifts to material flow and sticking<\/strong>.<\/p>\n

If cracking or detachment is concentrated around welds, bolts, or fastening locations, the fastening conditions, temperature, and vibration need to be checked before concluding that the cause lies in the lining.<\/p>\n

1.3. When the economic impact of a location needs to be evaluated<\/span><\/h3>\n

If the objective is not only technical identification but also determining the level of impact on operations, at least four data points need to be collected:<\/p>\n
