What is a Step by step roasting furnace? Introduction to the advantages and characteristics of heating furnace functions

Step by step roasting 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 Step by step roasting furnace

Step by step roasting 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.，is a kind of high quality and low price Step by step roasting furnace。

2、Structural characteristics of Step by step roasting furnace

The Step by step roasting furnace has the following structure

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. furnace chamber

A space for holding metallic materials for heating.

3. combustor

The device that mixes natural gas with combustion-supporting air and ejects it is the core component of the heating furnace.

4. 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.

5. 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.

3、Step by step roasting furnace function

Step by step roasting furnaceit has the functions of temper, hardening and tempering, normalizing, anneal and heat treatment，the principle is simple.Heat of combustion based on fuel. Natural gas is sprayed from the burner, mixed with combustion-supporting air and burned to produce high-temperature flame and smoke. These high-temperature flames and smoke transfer heat to the metal materials in the furnace by radiation and convection, so that they gradually heat up to the temperature required for forging.，is a common Step by step roasting furnace，energy-efficient,Easy to control,Easy to maintain,energy saving and environmental protection,Stable and reliable，has been favored by more and more customers.。
