The mill liner damage mill lining board damage is the main form of fracture, wear, deformation and shedding of three categories.
The first one: fracture
Fracture is the most serious problem in the manufacture and application of mill liners. The reasons for this kind of problems are related to the use of the mill. Generally speaking, the 5 problems are as follows:
1, the chemical composition design is reasonable or not accurate control of chemical composition;
2, there are serious quality problems such as metallurgy, exceed the standard inclusion segregation;
3, there are serious casting defects, such as shrinkage, porosity, porosity, poor casting microstructure;
4, the heat treatment process design is unreasonable or the heat treatment process is not accurate;
5, stress control and eliminate unreasonable production process, such as unreasonable design of casting process, casting loose box, unreasonable opening time, grinding, welding and improper heat treatment quenching time after tempering.
Second: wear
Liner by grinding body and material on the impact of the work, sliding and rolling, and accompanied by the effect of temperature is affected by water. Medium and electrochemical corrosion dual role in wet in the mill.
The third kind: deformation and fall off
Because the liner low yield strength and high ductility. A liner will hit, to the edge of ductile deformation occurred. Liner deformation of arch serious will bolt snapped, lining plate off, causing stop grinding accident.
Hunan Fengwei Wear Parts Foundry is a professional production of high manganese steel products manufacturers, product selection of high quality raw materials, through scientific and reasonable proportion of elements (Mo, Mn, La etc.), forming a medium frequency melting furnace, after a series of heat treatment (heat treatment temperature reaches 1045 degrees) after produced products of toughness and wear resistance can reach 1.2 to 1.5 times that of similar products. The products in the long term used in mining, metallurgy, thermal power, cement, sand mining, gold and other industries by the majority of customers praise. Honesty is the life the quality is the life of enterprise development, and sincerely you are welcome to cooperate! Dear friends to map calls made.
