Forged Back Up Rolls

The forged back up roll is a roll that supports the work roll and is the largest and heaviest roll used in rolling mills. The roll can support intermediate roll for the purpose of avoiding deflection of the work roll and affect on the yield and quality of the plate and strip rolling mill. The quality characteristics of the backup roll are high surface hardness, good hardness uniformity and the deep hardened layer of roll body, good strength and toughness of roll neck and roll body. The backup roll has high wear resistance and peeling resistance, strong anti-accidents.

Large Diameter Ring Gear

Introduction

Gear wheel, gear ring and segment ring gear are often used in mechanical transmission, which are often forged or cast structure high quality and strength alloy steel with surface carburizing or hardening treatment.The gear have the high bearing capacity and durable.In practical application, which is widely used in high speed and heavy load machinery, because of its stable transmission, low impact, vibration and noise.

Application

The large ring gear is the main component of the rotary kiln and ball mill, which needs to drive the entire barrel for a long time. Therefore, in actual production, the enterprise has very high quality requirements for the large ring gear.

Custom Support Roller Assembly

Rotary kiln’s support roller is an important module, and it has the character of large bearing load, poor working environment, constant running, and complex maintenance.

Rotary kiln support roller device can be divided into sliding bearing supporting roller group, rolling bearing supporting roller group and sliding-rolling bearing supporting roller group (radial sliding bearing, axial rolling bearing) according to the bearing used. Rolling bearing rollers can be divided into shaft type and mandrel type according to shaft rotation and non-rotation. Rolling bearing roller sets have the advantages of simple structure, convenient maintenance, low frictional resistance, reduced power consumption, and simple manufacturing. However, because the load of the roller can reach hundreds of tons, the size of the rolling bearing required is large and is limited by the supply conditions. However, with the improvement of industrial technology, rolling bearings will be used more and more in the supporting roller device.
