On August 1st, the double-flow straight curved slab continuous casting machine with world advanced level was successfully tested at the heat load test of Angang Iron and Steel Co., Ltd.
The continuous casting machine can produce slabs with a width of 2150 mm and a thickness of 250 mm. It adopts internationally advanced technology and has an annual output of 1.6 million tons. The main product positioning covers dozens of medium and high-end products such as high-grade pipeline steel, high-strength ship plate, container steel, engineering machinery steel, high-strength structural steel, etc., which can provide high quality for the Angang headquarters and the stock Bayuquan branch thick plate production line. Slab raw materials.
The completion and commissioning of the unit will play an important role in promoting the level of process equipment for the Angang Steelmaking System, producing high value-added, high-tech products and enhancing core competitiveness.
Naipu SP metal Vertical Slurry Pumps are vertical, centrifugal slurry pumps submerged in sump to work.They are designed for delivering abrasive,large particle and high density slurries.These pumps have no need of any shaft seal and sealing water. They can also be operated normally for insufficient suction duties.Wet parts of type NP-SP pump are made of abrasion-resistant metal. All parts of type NP-SP(R) pump immersed in liquid are lined with rubber outer liner.They are suited to transport non-edge angle abrasive slurry.
Typical Applications---
Sump drainage washdown
Floor drainage
Mill sumps
Carbon transfer
Monitoring
Magnetite mixing
