Abstract
Slab reheating furnace with waste gas jet preheating equipment is purposed for reductin of energy consumption and the improvement of productivity. This paper describes the utilization of this equipment with special reference to the reduction of energy consumption.
The high heat transfer coefficient is obtained by gas jet. The Waste gas of furnace is blown on the charged slabs at a high speed to preheat slabs. As a result, the heat of waste gas is utilized more by the new equipment than by the conventional furnace. Kawasaki Heavy Industries Ltd. has studied the heat transfer of gas jet under the conditions of a actual furnace and the application method of gas jet.
This equipment has been applied to No. 1 reheating furnace of new plate mill of Oita Works. Since January, 1977, the reheating furnace has been operated well without any equipment trouble and has improved energy consumption.
