Introduction to Stepping bottom quenching furnace, heating furnace advantages, characteristics and principles

Stepping bottom quenching furnaceIt is an important heating equipment before metal forging. It uses natural gas as fuel to heat metal materials through high-temperature flame and smoke generated by combustion to meet the requirements of forging process.。The following is to introduce the Stepping bottom quenching furnace:

1、Brief introduction of Stepping bottom quenching furnace

Stepping bottom quenching furnaceIt is a forging heating device using gas as fuel.，at work,The high-temperature flame and flue gas generated when the fuel burns in the furnace are used as heat sources to heat the medium flowing in the tube to reach the specified process temperature. Fuel is ejected from the burner and burned, resulting in high-temperature flame and high-temperature flue gas. The high-temperature flame transfers heat to the furnace tube in the radiation chamber through radiation, and then to the medium in the furnace tube. The high-temperature flue gas enters the convection chamber of the heating furnace upward due to the suction force of the chimney or the action of the induced draft fan, and the heat is transferred to the furnace tube in the convection chamber by convection, and then to the medium in the furnace tube.，is a kind of high quality and low price Stepping bottom quenching furnace，Simple structure and reliable operation.，the main structure includes Radiation chamber, ventilation system, furnace chamber, ventilation system and furnace chamber，the advantage is Efficient combustion and waste heat recovery system can significantly reduce energy consumption, thus reducing operating costs.、It can improve the plasticity and fluidity of metal materials, reduce the difficulty and cost of forging, and improve product quality and production efficiency.、Uniform heating and precise control can be realized, so it is helpful to improve the product quality and yield of metal materials.、Adopting advanced combustion technology and materials, it has a long service life and low maintenance cost.、Natural gas is used as a heat source, resulting in less waste gas and smoke after combustion, and less pollution to the environment. This will help reduce industrial emissions and improve the atmospheric environment.。

2、Stepping bottom quenching furnace structure

The Stepping bottom quenching furnace structure is introduced as follows:

1. combustor

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

2. ventilation system

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

3. furnace chamber

A space for holding metallic materials for heating.

4. Radiation chamber

The heat load of the main place for Stepping bottom quenching 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.

5. 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.
