Title: Innovations of Lixin Zhou in Steel Manufacturing

Introduction

Lixin Zhou is a notable inventor based in Hubei, China, recognized for his contributions to the field of steel manufacturing. He holds 2 patents that focus on enhancing the quality and reliability of steel products. His work is particularly significant in the context of low-carbon nitrogen-containing austenitic stainless steel and steel for wind power gears.

Latest Patents

One of Lixin Zhou's latest patents is a method for manufacturing a low-carbon nitrogen-containing austenitic stainless steel bar. This innovative method involves a sequence of processes including smelting, electroslag remelting, and forging. During the electroslag remelting phase, the steel ingot from the smelting process is utilized as an electrode bar, which is remelted with a specific slag composition. The slag comprises CaF (65-70%), AlO (15-20%), CaO (5-10%), and MgO (2-5%) by weight. The forging methods employed include upsetting-and-drawing and radial forging, which ensure the production of high-strength steel with a uniformly distributed chemical composition.

Another significant patent by Zhou is related to steel for wind power gears, which emphasizes improved purity and reliability. The chemical composition of this steel includes specific percentages of carbon, silicon, manganese, phosphorus, sulfur, chromium, molybdenum, nickel, and aluminum, with iron as the primary component. The smelting method involves primary melting in a converter, refining in a furnace, and continuous casting followed by electroslag remelting. This process enhances the purity of the steel, significantly reducing large-particle inclusions and improving the flaw detection pass rate.
