Abstract

PURPOSE: To heat high temp. steel materials and ordinary temp. steel materials efficienty and improve thermal efficiency for heating by segmenting a heating furnace for steel materials for rolling to a moving hearth type heating furnace and a stationary hearth type preheating furnace, and preheating the steel materials in the preheating furnace with the high-temp. waste gas of the heating furnace.
CONSTITUTION: The heating furnace for steel materials 3 for rolling is constituted of a moving hearth type heating furnace A for charging high temp. steel materials and a stationary hearth type preheating furnace B for charging ordinary temp. steel materials, and a freely vertically movable partition wall 1 is provided between both furnaces. The high temp. steel materials are charged through the charging port 7 provided in the side part of the heating furnace A into the furnace and while being conveyed in the furnace by a moving hearth 2 such as walking beam, they are heated to intended temps. by burners 8,8' and are taken out through an extraction port 4. The ordinary temp. steel materials are charged through the inlet 11 of the preheating furnace B, are moved on a stationary hearth 6 by a pusher 10 and are preheated by the high temp. waste gas from the heating furnace A entering from the boundary (a) of both furnaces A,B, after which they are entered into the heating furnace A by the moving hearth 2 of the heating furnace A, whereby they are heated.
