Refractory ceramic fiber board used in metallurgical furnaces(2)

Furnace in the smelting process with the temperature difference between inside and outside will lead a waste of heat, refractory ceramic fiber board to maintain the efficient operation of metallurgical kilns. Last week we talked about applications of CCEWOOL refractory ceramic fiber board in Soaking furnace and pushing steel continuous heating furnace, and this week we will introduce the application of refractory ceramic fiber board in Walking beam reheating furnace, annular heating furnace and trolley type furnace.

1. Walking beam reheating furnace

Walking beam-reheating furnace is a mechanized furnace that relies on a special Walking beam machine to move the billet in the furnace, and its basic characteristic is the movement of the billet on the bottom of the walking beam. This movement is relying on the movable bottom-walking beam making the Rectangle track ‘s reciprocating motion. The billet placed on the fixed beam is sent from the entry side to the exit side. Refractory ceramic fiber board can generally be used for preheating section wall lining materials, heating, soaking segment wall lining insulation; flue system wall lining materials and hot air pipe bandage materials.

2. Annular-heating furnace

Annular heating furnace is also a type of continuous heating furnace, is composed by the chamber of annular furnace and the bottom of rotary furnace. Annular heating furnace is mainly used to heat the round billet and abnormity billet (such as wheel rim blank), can also heat square billet, generally used for steel forging and heating steel billet before rolling, can also be used as heat treatment. The inner wall of the annular heating furnace will expand in the direction of the inner shell after heating, and the masonry is easy to collapse, and reinforcement measures are necessary. As the refractory ceramic fiberboard has good thermal stability, so refractory ceramic fiber board will fit with ceramic fiber module corresponding to the temperature together to lay a all refractory fiber lining.

3. Trolley type furnace

The furnace type furnace is an intermittent warming furnace (furnace in operation, the temperature varies with time), the chamber of furnace is not divided into section, the furnace temperature is changed according to the provisions of the heating system with time program, for ingot (or billet) Heating or work piece heat treatment. Traditional dense refractory wall lining has the characteristics of high furnace Heat dissipation and heat storage loss, and low furnace thermal efficiency. The refractory ceramic fiberboard as the wall lining material and automatic control of trolley type heat treatment furnace, the thermal efficiency is up to 40%, significantly reducing the cost of equipment investment, and light and efficiency of the furnace structure.

CCEWOOL refractory ceramic fiber board is generally used for preheating section wall lining materials, heating, soaking segment wall lining insulation; flue system wall lining materials and hot air pipe bandage materials. Good compressive strength, smooth surface, accurate size, easy to install.
