Slewing ring Bearings are commonly used in modern industrial components, compact structure, convenient guide rotation, simple installation, easy maintenance, which is widely used in lifting the transport machinery, mining machine, construction machinery, port machinery, wind power generation, medical equipment, the radar and missile launcher and other large rotary device. FRB Bearings would briefly introduce, the several key problems affecting slewing ring manufacturing.
Slewing ring bearings manufacturing furnace temperature and heating speed
1. Carbon steel, alloy steel, normalizing furnace charging requirements bottoms in less than or equal to the processing temperature furnace, the furnace temperature, alloy structural steel, alloy tool steel annealing requirements under 550 ℃ furnace charging, along with the furnace heating up.
2. High speed steel and complex differential cross section larger easy low temperature furnace charging, and mean temperature between 550-700 ℃ with the furnace heating up after 1 to 2 hours.
