High alumina castable used in heating furnace(2)
In the metallurgical industry, the heating furnace is used to refer to the metal is heated to rolling into the industrial furnace temperature forging, including continuous heating furnace and furnace etc.. Metal heat treatment heating furnace and the other called heat treatment furnace. Before blooming heating ingot or the furnace internal temperature of ingot homogeneous called soaking pit. Broadly speaking, the heating furnace also comprises the soaking furnace and heat treatment furnace.
Continuous heating furnace comprises a pusher type furnace, walking beam furnace, rotary hearth furnace, furnace chamber type continuous heating furnace, but the habit is often referred to as the pusher type furnace. Continuous heating furnace for heating the metal most before rolling billet, a few for forging and heat treatment. The main features are: the continuous movement of the billet in the furnace in rolling rhythm, furnace gas is continuous flow in the furnace; the general situation, the section size, charge the variety and yield under the condition of invariable, metal material of each part of the furnace temperature and furnace temperature basically does not change with time and only along the length of the furnace change.
