Rotary kiln supporting wheel: 7~60 T, rotary kiln supporting wheel, cement rotary kiln supporting wheel, lime rotary kiln supporting wheel. Luo mine specializing in the production of citic heavy industry rotary kiln supporting wheel, luo mine rotary kiln supporting wheel. Including cement rotary kiln supporting wheel, lime rotary kiln supporting wheel, metallurgical rotary kiln supporting wheel, chemical rotary kiln supporting wheel and other rotary kiln supporting wheel. Rotary kiln supporting wheel is an important part of rotary kiln supporting device, which consists of supporting wheel bearing group and welding base. Large rotary kiln roller bearing group generally adopts the sliding bearing, the wheel, shaft, bearing, spherical and bearing roller is one of the key parts on the rotary kiln equipment, it equipment under rotating load, in a larger work under alternating stress state, so the internal quality of the wheel casting the demand is higher, are not allowed to exist obvious casting defects. In my company for a factory production of 6.4 m * 6.2 / phi phi 90 m rotary kiln roller as an example, the product net weight 44.1 t, material for ZG42CrMo, maximum diameter of 2800 mm, 1400 mm high, the maximum thickness of 830 mm, according to the level of GB7233 Ⅱ and Q/HMZ402-2002 ultrasonic NDT magnetic powder.

Selection of supporting wheel material of rotary kiln

In general, the rotary kiln supporting wheel is more than 20HB hardness than the outer circle surface of the belt. In the calcining operation of rotary kiln, the material selection of its supporting wheel is extremely important. Generally speaking, we will choose the tug of the right material to intervene in the production according to the actual operation of rotary kiln, and there is a reference scale in the process of external selection.

In the actual operation of rotary kiln supporting wheel, if the diameter of kiln used is less than 4 meters, the material used should be higher than JC/T401.2 and zg340-640 related criteria, and the castings involved in the production need to be normalized and tempered, after processing, the surface hardness of the outer circle is higher than 190HB.

After meeting all the above mentioned reference standards, the application of the supporting wheel in the calcining of rotary kiln materials will be more effortless, and it also provides a basis for the efficient production of rotary kiln. If the rotary kiln diameter is more than 4 m, the material should be higher than JB/T6402 and ZG42CrM0 related criteria.

cars only The difference between the thickness of rim and hub of rotary kiln after processing is generally maintained at about 5% of the dimension.

The coaxiality tolerance of the outer circular table in the rotary kiln facing the shaft holes should refer to the choice of GB/ t1184-1996 accuracy higher than grade 8 and the diameter of the outer circle. The tolerance of the outer cylindrical surface and the cylindricity of the supporting wheel should be 0.2 mm. The casting also needs to be normalised and tempered, and the external surface hardness after treatment is higher than 200HB.
