The journey of Egyptian customers and Huichengsheng

In the field of industrial heat treatment equipment, Huichengsheng has gradually become a trusted partner of global customers with its product concept of "good-looking, easy to use and durable", as well as continuous technological innovation and service upgrades. The cooperation process between a pond production company in Egypt and Huichengsheng is the livestock cry of this concept-from the first introduction of a continuous atmosphere protection stainless steel kitchen sink bright passivation furnace in 2018 to the purchase of a series furnace (HCS-70 model) in 2024, the cooperation between the two parties not only witnessed the leap in equipment performance, but also showed the global influence of China's manufacturing towards high-end and transformation.

1. First cooperation: Bright annealing furnace opens a new chapter of efficient production

In 2018, Egyptian customers urgently needed to upgrade the heat treatment production line of stainless steel kitchen sink due to business expansion needs. The traditional annealing process has problems such as surface oxidation, high energy consumption, and poor consistency, which makes it difficult to meet the requirements of the high-end market for product finish and performance stability. After several rounds of technical communication, the customer finally selected Huichengsheng's continuous atmosphere protection stainless steel kitchen sink bright annealing furnace. The equipment uses imported nickel alloy muffle furnace body and intelligent temperature control system, and forms a protective atmosphere through the nitrogen and hydrogen mixed gas (75%H₂+25%N₂) generated by the decomposition of liquid ammonia, achieving the following breakthroughs:

Zero surface oxidation: After annealing, the surface of the product is as bright as a mirror, and no subsequent polishing is required, saving more than 30% of labor costs;

Precise temperature control: The temperature control accuracy reaches ±1℃, ensuring the uniformity of material structure, and the product qualification rate is increased to 99.2%;

Continuous production: The steel belt conveyor system supports stepless speed regulation, and the daily production capacity of a single line reaches 12 tons.

2. Technology upgrade: Alliance decomposition furnace solves the cost dilemma of protective gas

As production capacity expands, customers find that liquid ammonia directly uses a quarter of the pain points: one is the high transportation cost, and the other is that the gas deviation fluctuation affects the quality of the amplifier. In 2024, Huichengsheng launched its self-developed HCS-70 ammonia cracker furnace, which converts liquid ammonia into high-purity nitrogen and hydrogen through catalytic hydrogen oxidation technology, providing customers with a more economical mixed gas solution

According to statistics, Huichengsheng equipment has been exported to 37 countries, of which continuous atmosphere furnace protection accounts for more than 60%, becoming a new benchmark for "China's smart manufacturing" going overseas.

Conclusion

From the Egyptian desert to the banks of the Nile, Huichengsheng's annealing furnace and ammonia decomposition furnace continue to operate, witnessing how a Chinese company wins the trust of global customers with technological innovation and service sincerity.
