Hearth rolls structure optimization and cost control (3)

3. Optimization of the structure of hearth rolls:                                 Link above (1). Diameter of outstretched shaft affect the mechanical properties of the hearth rolls. In Figure 3 shows the results below we can see, with the increase of the diameter, the value […]

Hearth roller structure optimization and cost control(2)

Link above -Hearth roller structure diagram  show Fig 1 2. Finite element analysis of a hearth roll 1) Establish finite element model of the size of the actual structure of the hearth roller. Using software ANSYS of finite element analysis to analysis. In the modeling process of hearth roller  finite element and even more simplify […]

Hearth roller structure optimization and cost control(1)

INTRODUCTION Hearth roller is a typical centrifugal casting pipe fittings. It is one of the important components in support of metallurgical equipment and transport slabs. As a result it has wide application in Continuous casting- rolling production line. In the rolling process first of all to heat the steel slab to 1050 ~ 1150 ℃ rolling […]

Sink roll bush structure improvements(3)

Link above -Sink roll bush structure improvements 3 c. Considering the material expansion coefficient of Sellite6 alloy and 00Cr17Ni14Mo2 is not the same. The proper clearance retained between part 2 and part 4. And to prevent zinc adhesion between part 2 and part 4 causes applied force to part 2. That is because sink roll […]

Sink roll bush structure improvements (2)

Link above The cracks were found on Stellite6 alloy block part after the structure put into use a period. After analysis the cause of cracks is the welded structure of Stellite6 alloy block and sink roll bush body. In the production the line is under high temperature environment of greater than 600 ℃.The state returns […]

Sink roll bush structure improvements (1)

The CGL unit annual output 250000 ton, produce width of 800 ~ 1 300 mm, thickness of 0. 3 5 ~ 2. 0 mm. The product varieties are full of hard grade, commercial-grade, high-strength steel. The application are mainly household appliances industry and the construction industry and other fields. Sink roll is located just above […]

Hearth roll of continuous annealing furnace

Hearth roll is one of the most important part of continuous annealing furnace. Its working condition is the decisive factor if annealing furnace can be normal production. Work and structural features of a hearth roll Structures and materials of hearth roll Working at over 800 ℃ in the furnace and rotation under load, meantime mechanical […]

Centrifugal casting stainless steel products

      Radiant tubes type: U-type, W-Type, 0-Type, P-type, L-Type, S-Type. Similarly straight-type and also electric radiant tubes. Application: One of centrifugal casting stainless steel products. The radiant tubes are working at high temperature environment on average: 800-1200° C. Therefore most of them are used for indirect heating to furnace like CAL (continuous annealing line). […]
