Titanium alloy, known as "space metal," is a key material in cutting-edge fields such as aerospace, marine engineering, and high-end medical applications. However, the production of titanium from sponge titanium to finished products requires dozens of processes, including vacuum arc melting, multiple rounds of forging, rolling, extrusion, and pickling. Among these, heat treatment, as one of the core processes in rolling, plays a decisive role in shaping product performance. Recently, MCC Southern Thermal Engineering achieved a major breakthrough in the field of non-ferrous metal heat treatment equipment—pioneering the technology for vertical bright annealing furnaces for wide titanium strips, building the world's first bright annealing furnace for wide titanium strips, and globally achieving the first continuous production of 1400mm wide titanium strips.

Long-Standing Reliance on Foreign Technology for Wide Titanium Strip Heat Treatment

Titanium and its alloys possess high strength, low density, excellent corrosion resistance, non-magnetic properties, as well as good thermal strength and low-temperature performance, making them core materials in high-end fields such as aerospace, marine engineering, and petrochemicals. However, the performance of non-ferrous metals is not "peak at the factory gate."

In the titanium production process, the precision of heat treatment directly determines the mechanical properties and service life of the final product. Each heat treatment step—annealing, solution treatment, aging—requires precise control: furnace temperature uniformity, atmosphere protection, cooling rate... Every parameter reflects the capability of heat treatment equipment and technology.

Bright annealing of wide titanium strips (up to 1400mm in width) has long been recognized as a "tough nut" in the global heat treatment equipment field. Titanium is highly prone to oxidation at high temperatures, so the annealing process must be carried out in a protective atmosphere or vacuum environment. Additionally, wide titanium strips demand extremely high furnace temperature uniformity; even slight deviations can lead to uneven performance and degraded surface quality across the entire coil. Previously, this core technology was long held by a few foreign equipment manufacturers, becoming a key bottleneck restricting the development of China's high-end titanium industry.

Breakthroughs in Four Core Equipment Types

MCC Southern Thermal Engineering has focused on the metallurgical industrial furnace field for 70 years, establishing a technical equipment system covering multiple furnace types. In the field of heat treatment for non-ferrous metals and their alloys, the company has achieved independent innovation in several core equipment types:

World's First Vertical Bright Annealing Furnace for Wide Titanium Strips: Globally Achieves First Continuous Production of 1400mm

MCC Southern Thermal Engineering pioneered the technology for vertical bright annealing furnaces for wide titanium strips, building the world's first such furnace and globally achieving the first continuous production of 1400mm wide titanium strips, filling an industry gap.

This breakthrough signifies that China's high-end titanium heat treatment equipment has moved from "catching up" to "leading." Compared to traditional horizontal furnaces, the vertical annealing furnace design offers significant advantages in strip running stability, atmosphere uniformity, and thermal efficiency, making it particularly suitable for continuous bright annealing of wide, thin-gauge titanium strips.

Pure Electric Heating Roller Hearth Heat Treatment Furnace: Simultaneously Processes Titanium Plates and Strips

To meet diverse plate and strip heat treatment needs, MCC Southern Thermal Engineering developed a pure electric heating roller hearth heat treatment furnace capable of processing both titanium plates and strips. The pure electric heating solution eliminates traditional gas heating, achieving zero combustion emissions during heat treatment, while offering higher temperature control precision and faster response, providing a green solution for high-quality titanium heat treatment.

China's First Pure Resistance Strip Heating Roller Hearth Furnace with Automatic Quenching Function: Three Functions in One Furnace

More critically, MCC Southern Thermal Engineering built China's first pure resistance strip heating roller hearth heat treatment furnace with automatic quenching function. This furnace achieves three functions in one unit—titanium plate annealing, semi-finished product solution treatment, and finished product solution treatment—with furnace temperature uniformity meeting the requirements of the aerospace standard AMS2750H.

AMS2750H is one of the most stringent high-temperature measurement standards in the international aerospace field. Meeting this standard marks that the heat treatment equipment has reached international aerospace-grade quality levels, suitable for applications with extremely high material performance requirements, such as aircraft engines and airframe structural components.

Autonomous Core Equipment for Pre-Processes: Porous Media Combustion, Electromagnetic Induction Heating, Air Cushion Furnace

In the pre-processes of non-ferrous metal production, MCC Southern Thermal Engineering independently developed core equipment including porous media combustion equipment, high-power electromagnetic induction heating equipment, air cushion furnaces, and resistance strip heating systems, constructing copper bar heating furnaces, titanium/nickel/zirconium and their alloy coil (plate) heating furnaces, and supporting alkali furnaces.

Among these, porous media combustion technology is a revolutionary technology in the international combustion field, significantly improving combustion efficiency and reducing nitrogen oxide emissions. High-power electromagnetic induction heating equipment achieves efficient and clean metal heating, with products widely used in high-end fields such as aerospace, shipbuilding, and nuclear power.

The industrial furnace itself also achieves the goals of reducing overall furnace energy consumption and pollutant emissions, aligning with the green transformation requirements of the manufacturing industry under the "dual carbon" goals.
