Henan Xintengfei Casting Steel Co., Ltd.: Large-scale steel castings and large gear rings, forging reliable quality with solid strength

In heavy equipment sectors such as mining, cement and metallurgy, large steel castings including large gear wheels serve as core transmission components. Their quality directly determines the stable operation and safety of the entire production line.Faced with uneven casting quality in the market, how to find a large steel casting manufacturer with strong technology and reliable reputation? Henan Xintengfei Casting Steel Co., Ltd. has provided the answer through numerous successful cases.

Technology: Successfully cast an 80-ton extra-large gear.

The core strength of Henan Xintengfei Casting Steel is first reflected in its capability to produce large tonnage steel castings.The company has successfully customized and manufactured a large mill gear with a diameter of φ8221 for Metso Corporation.

The gear blank has a single weight of nearly 80 tons and is made of high‑grade ZG45CrMo steel.In addition to its large weight, it must simultaneously meet the Level 1 inspection standards for both UT (ultrasonic testing) and MT (magnetic particle testing), which are common domestic requirements.To ensure success, the technical team of Xintengfei Casting Steel used digital simulation pouring technology for repeated deductions and pre‑assessed potential risks in production, achieving one‑step successful pouring with a total molten steel volume of 140 tons.This demonstrates its advanced technical level in the production of large cast steel gears.

One-Stop Service: Seamless Connection from Blank to Finished Product.

In addition to its strong casting capacity, Henan Xintengfei Casting Steel also provides comprehensive one stop supporting services.The company has its own independent machining base equipped with large CNC processing equipment such as a 10 meter gear hobbing machine, 8 meter heavy duty vertical lathe, boring and milling machine, and others.This means customers can complete the entire process from blank casting and heat treatment to precision machining without outsourcing to external factories.It not only saves the trouble of coordinating intermediate links but also guarantees the tooth profile accuracy and delivery schedule of finished gears from the source.
