Medium Thick Steel Plate

We are the biggest manufacturing base of rolling element blanks for bearings in China, with a market share over 70% for 10 years.

We use near net shape forging technology, the product has high contact fatigue life, stable process and reliable quality.

We produce a full range of bearing steel ball blanks with specifications ranging from φ19.844 mm to 90 mm. We have strong supply guarantee capabilities with complete varieties, and thousands of tons of inventory.

Heavy-duty forging presses (140MN and 66MN) can meet the product process design requirements and ensure the result of the product's internal structure, surface flatness and dimensional accuracy.

With more than 40 industrial furnaces of various types, we are able to control product process temperature accuracy and ensure the delivery period.

Common thickness ranges from 6 to 400 mm, with the maximum thickness of 800 mm, meeting the full range of customer needs.

The matching intermediate billet water-penetrating device can effectively handle rolling under differential temperature. Resulting the design of no niobium ship plate, this design can reduce alloy costs significantly.

The maximum opening of the four-roll main rolling mill is 1100mm, with the 9000 tons maximum rolling force, 1210kn.m torque, and the maximum reduction of a single pass is 60mm. The rolling capacity matches the conventional 5000 mm rolling mill, and it is equipped with a separate vertical rolling mill with the industry's largest rolling force of 800 tons. The core deformation capacity and grain refinement of the steel plate are significantly better than other manufacturers.

The water volume/hour of the DQ+ACC cooling system reaches 9,000+9,000 cubic meters, which is the largest volume in the industry, and the cooling system is running with online temperature compensation technology.

The entire production line is intelligently controlled and fully automatic. The ACC entrance is equipped with an advanced pre-straightening machine, and the hydraulic system adopts full servo drive.
