Can-Eng Furnaces International Ltd. received the final acceptance certificate from Indian steelmaker SAIL for a roller-hearth plate quench-and-temper system. It is designed to heat treat a wide range of plates from 0.25-4.0 inches (6-100 mm) thick x 118 inches (3,000 mm) wide up to 42.5 feet (13 meters) long in a variety of grades for commercial and non-commercial applications. With an overall line length of 400 feet (122 meters) and a restrained roller spray quench at the heart of the system, the heat-treatment process results in true flat plates with metallurgical properties that exceed contractual requirements. The auto-recuperative radiant-tube-fired atmosphere roller-hearth hardening furnace and direct-fired temper furnace run off coke-oven gas (COG), a byproduct of the steelmaking process.

Bodycote will open a new heat-treatment facility in Elgin, Ill. The purpose-built facility, which is scheduled to be operational in June 2020, has been designed as a replacement for Bodycote’s aging plant in Melrose Park, Ill. It will support manufacturing supply chains in the Midwest region. The Melrose Park facility will be closed once the transfer of customers’ work has been completed. According to Bodycote, the investment allows it to expand capacity and improve its ability to deliver high-quality heat-treatment capabilities.

Tempering occurs by heating the steel to below its critical temperature in order to transform the metastable body-centered tetragonal martensite structure that is formed during quenching into a more stable structure of fine carbide particles.

Dependable Metal Treating is observing a milestone anniversary in 2020. It should be quite a celebration because the company has come a long way in a relatively short period of time.

Rapid phase transformation and high thermal gradients that occur during quenching can cause distortion, which can lead to costly hard machining and rejection.

If combustion and its related efficiencies were not challenging for us, we and others would not dedicate so many new resources to the topic. This article will point out some of these available resources, including the pages of Industrial Heating.
