Founded in 1965, was born in Pittsburgh, Pennsylvania, an old industrial zone in the northeast of the United States. Pittsburgh, which is close to coal mines and iron mines and uses the water system of the GreatLakes to transport iron ore, later developed into the steel industry center of the United States, with a number of steel mills distributed intensively.

With the booming of the iron and steel industry, the safety of oxygen melting and burning in the steelmaking process has attracted industry attention. As a combustion supporting agent, oxygen produces strong redox reaction in the melting and burning process. The leakage of oxygen threatens the personal safety of users, and burns occur from time to time.

Smartmelter^®cooperates with American Steel Company and Clareton Steel Company to develop a new generation of oxygen burning lance. Smartmelter O₂-burning lance safety equipment uses the special high- pressure valve for hard sealed oxygen, and is equipped with the patented design of anti-tempering and anti-slag return integrated lance head.

The temperature that the oxygen delivery hose can withstand ranges from - 30 ° C (- 22 ° F) to + 70 ° C (158 ° F). The outer layer of the lance is made of high-strength synthetic wire and heat-resistant glass fiber fabric, which can withstand heat radiation up to + 530 ° C (+ 986 ° F). At the same time, it can prevent sparks from splashing, cutting and scraping. The integral drum of the lance has the characteristics of high strength, and the telescopic life can reach 300000 times.

The above components constitute a highly safe and durable Smartmelter O₂-burning lance safety equipment, ensuring that users can burn oxygen in a safe environment.

Smartmelter O₂-burning lance safety equipment has obtained UL certification (UnderwriterLaboratories Inc.) in the United States. The Safety Testing Institute is the most authoritative organization in the United States and a worldwide organization engaged in safety testing and identification. UL certification is a non mandatory certification in the U.S. that ensures testing and certification of product safety performance.

ETL certified electrical testing laboratories enjoys a high reputation in the United States and around the world.Like UL and CSA, ETL can test and issue ETL certification marks according to American national standards, or test and issue composite certification marks according to UL standards, American national standards, CSA standards or Canadian standards. Any electrical, mechanical or electromechanical product with the ETL mark indicates that the product has met the minimum requirements of the generally recognized product safety standards of the United States and Canada, and it has been tested to meet the relevant product safety standards. It also means that the production factory agrees to receive strict regular inspection to ensure the consistency of product quality and can be sold to the markets of the United States and Canada.

ETL also requires that its production site has been inspected, and the applicant agrees to conduct regular follow-up inspection of its factory thereafter to ensure that the products always meet this requirement.

After more than 50 years of development, Smartmelter O₂-burning lance safety equipment series products have been distributed in major steel mills all over the world, and are widely used in copper, aluminum, cement and other industries. Smartmelter O₂-burning lance safety equipment always takes leading the development of oxygen melting technology and delivers the safety of oxygen burning!
