Material Analysis Of Roller Surface For Briquette Press Machine

Material Analysis of  Roller Surface for Briquette Press Machine

For the Briquette Press Machine, the roller is one of the most critical parts, plays an important role, the life of the roller Briquette Press Machine to determine the use of time, while the roll is the only Briquette Press Machine wearing parts Therefore, at the time of purchase, it is important to check the pressure of the briquetting machine, which not only can guarantee the quality of the briquetting machine, but also can effectively reduce the equipment cost and improve the economic efficiency.

Briquetting machine roller material is divided into 65 manganese, 9 chromium 2 molybdenum, high chromium alloy. To suppress the different materials to use a different briquetting machine roller skin: 65 manganese material roll more popular, are cast steel, low cost, generally used for small briquetting machine, such as briquetting machine, Can be suppressed pulverized coal, coke powder charcoal powder and other materials; 9 chromium 2 molybdenum, high chromium alloy briquetting machine roller is forging pieces, mainly used in large and medium-sized high-quality coal briquette press machine, , Iron powder, magnesium oxide powder, red clay and so on.

65 manganese is a common spring steel, with high hardenability, the surface decarburization tendency is smaller than the silicon steel, the heat treatment after the comprehensive mechanical properties better than carbon steel, but there are overheating sensitivity and temper brittleness. Bearing steel with high hardness, uniform hardness, high elasticity limit, high contact fatigue strength, the necessary toughness, a certain hardenability, corrosion resistance in the atmosphere of the lubricant. From the above material analysis is not difficult to see bearing steel as a roller material will be more economical than 65Mn durable, longer life, pressure ball machine and other equipment, the best choice for roller material.

Forging 9 Chromium 2 molybdenum roller skin is quenched to complete, through the quenching and tempering roll to obtain good mechanical properties, improve the physical and chemical properties of steel. The process is to heat the roll to Ac3 or Acm above the appropriate temperature, the appropriate time after the insulation in the air to get pearlite-like heat treatment process. Purpose: to obtain a certain hardness, refine the grain, get a more uniform organization and performance. Role: to eliminate a processing defects, to provide the appropriate state of the organization or get the appropriate mechanical properties. After the quenching of the powder pressure ball machine roll skin are generally to be tempered to reduce or eliminate the quenching stress, improve toughness and plasticity, access to hardness, strength, plasticity and toughness with the appropriate to meet some of the performance requirements of the roll.

Roller is a briquetting machine is an essential component, the briquetting machine roller skin determines the pressure ball machine to suppress the shape of the pressure ball machine roll is included in the pressure ball machine roll core outside the surface layer digging A cylindrical member having a ball and socket. According to the different ways of assembly into one and split.


Roller quality is related to the briquetting machine quality and life problems, some of the raw materials to suppress relatively hard, often easy to wear roller, so the choice of briquetting machine must take into account the quality of roller quality problems, to use high-intensity Wear-resistant materials, can avoid the wear of the roll, greatly increasing the service life of pressure ball machine.
