Austrian refractories manufacturer Rath successfully developed the refractory lining of a test roller furnace for the ceramics industry

A DRI (direct reduced iron) smelting furnace has been launched to substitute blast fur-naces used in ironmaking and steelmaking. It is one of Metso Outotec’s solutions for decarbonization of the iron and steel industry.

In the U.S. manufacturing sector, the steam and a large percentage of electricity is produced by using fuels such as natural gas, coal or other types of byproduct fuels.

Can-Eng Furnaces International Ltd. has been contracted to engineer and commission a continuous quench-and-temper furnace system for a North American manufacturer of mining, construction and material-handling products. This equipment will be part of an automated manufacturing cell and will be fed automatically from upstream handling equipment. Special considerations have been made to precisely control the quench temperature to reduce hardness variations and improve overall part quality. The multi-zone belt-style temper furnace employs high-efficiency, natural-gas-fired heating and recirculation systems, which have been proven to provide superior temperature uniformity in demanding applications. Can-Eng’s engineered control system, which controls and monitors the equipment, utilizes an Allen Bradly PLC and HMI. 

Many demanding applications require plants to operate at higher temperatures to increase efficiency and/or burn lower-quality fuels. 

Simulation has nearly limitless applications and has revolutionized engineering developments in manufacturing.

If your furnace is a bottleneck in your operation, it may be time to consider adding a new one. This article reviews the basics of furnace structure and style, refractory selection and combustion design. It concludes with a recent case study.

A customized furnace from SECO/VACUUM, a SECO/WARWICK Group company, has been used to heat treat the seventh and final module of the world’s largest superconducting magnet ever made. General Atomics finished the five-week heat-treating sequence on the last of the seven modules: six to be stacked together to form the most powerful magnet ever built and one on standby for repairs. In order to convert the 3.7-mile-long (6-km-long) stainless-steel-jacketed coil of niobium-tin conductors into superconductors, each of the 13-foot x 6.5-foot (4-meter x 2-meter) 110-ton solenoid sections was heat treated for five weeks, exceeding 1202°F (650°C) at its peak. 

Industrial furnaces are used for various heating processes – from low to very high temperatures – in industries such as steel, ceramics, refractories, glass and many more.

This furnace has a vertically oriented, large cylindrical heated chamber.
