What is a Stepping bottom annular heating furnace? Introduction to the Working Principle of heating furnace

Stepping bottom annular heating furnaceIt is a kind of equipment that uses natural gas as fuel to heat metal materials and make them reach forging temperature.。

1、Brief introduction of Stepping bottom annular heating furnace

Stepping bottom annular heating furnaceIt is a kind of heating equipment using natural gas as fuel, which is mainly used to heat metal materials to the required forging temperature in a short time.，multifunctional, with functions such as heat treatment, normalizing, anneal, hardening and tempering and Forging heating，it is an ideal choice for customers to buy Stepping bottom annular heating furnace。

2、Stepping bottom annular heating furnace structure

The Stepping bottom annular heating furnace structure is introduced as follows:

1. Waste heat recovery system

Used to recover the exhaust heat of the heating furnace. There are two kinds of recovery methods, one is to recover by preheating combustion air, so that the recovered heat can return to the furnace again; The other is to use another recovery system to recover heat. The former is called air preheating mode, and the latter is usually called waste heat boiler mode.

2. convection chamber

The material is heated by convection heat transfer of high temperature flue gas discharged from the radiation chamber. Flue gas washes the tube wall of the furnace tube at a high speed to carry out effective convection heat transfer, and its heat load accounts for about 20%-30% of the whole furnace. The convection chamber is generally arranged above the radiation chamber, and some are placed on the ground alone. In order to improve the heat transfer effect, nail head tubes or finned tubes are often used in furnace tubes.

3. Radiation chamber

The heat load of the main place for Stepping bottom annular heating furnace heat exchange accounts for about 70%-80% of the whole furnace. The furnace tube in the radiation room conducts heat through flame or high-temperature flue gas, which is mainly radiant heat, so it is called radiation tube.

4. ventilation system

Ensure the gas flow in the furnace and maintain the stability of the atmosphere and temperature in the furnace.

5. furnace chamber

A space for holding metallic materials for heating.
