large casting steel gear ring spur gear girth gear for mining machine
Spur gears are widely accepted as the most efficient type of gearing solution, when the application of transmitting power and uniform rotary motion from one parallel shaft to another is required. Determined by the center distance, spur gears create a steady functioning speed drive. This drive speed can be decreased or increased by the variable number of teeth that exist in the driving gear.

Mill Girth Gear
Several of our custom spur gears have been used in gear train applications - where multiple gears are required to have the same pressure angle and diameter pitch. They are available in plastic, non-metallic, brass, steel and cast iron. In addition ,these parts are manufactured many style types: plain, web, web with lightening holes, and web with spokes. Many are available with or without hubs.

Smelting casting |
1. Choose low S.P pig iron, select scrap steel, auxiliary materials and alloy of baking furnace according to process 2. According to special process smelting, make steel S.P hazardous elements meet internal control standards 3. The finished molten steel is treated with argon blowing in the ladle and R-H vacuum circulation degassing to make the molten steel composition uniform, harmful oxygen (H, O) reduction, uniform temperature, increase the fluidity of molten steel, so as to ensure good liquid replenishing of the casting and prevent the casting from porosity and other defects Strictly control casting temperature and casting speed according to the provisions |
50 t furnace R-h vacuum circulation degassing equipment for ladle argon blowing device
|
1. Furnace materials must meet the technological requirements 2. Control feeding temperature, feeding quantity, pure boiling time, steel temperature 3. The direct reading spectrometer is used to quickly detect the chemical composition in front of the furnace to ensure that the equipment is in the best state during melting and the chemical composition of the finished product meets the requirements during pouring 4. Check the parameters of argon blowing and R-H vacuum treatment 5. Check the starting temperature and Pouring time
