Processing and manufacturing strength 
We have several sets of hobbing machines with a diameter of 3m-10m; several sets of various submerged arc welding machines; we have processing equipment such as heat treatment electric furnaces and CNC vertical lathes and CNC lathes, with mechanical performance testing, impact testing machines, UT and MT flaw detection equipment Complete testing system
Production Process Introduction 
Making wooden molds, modeling, smelting and pouring, heat preservation, pit clearing, heat treatment, roughing, finishing,inspection, and delivery

Product quality inspection
1.  Before machining, control the dimensions according to the tolerance casting; ensure the precise control of the internal quality of the casting;
2.  During processing, the inspection of the bearing surface is carried out. The main inspection techniques are: ultrasonic inspection (UT), magnetic particle inspection (MT), and color inspection (PT). As a whole, it can reach level three flaw detection, and key parts can reach level two flaw detection; improve the stress capacity and wear resistance.
3.  After processing, strict inspection before leaving the factory to ensure the hardness and abrasion resistance of the vertical rollers, sand blasting equipment effectively assists and improves the surface quality.
