Bogie hearth tempering furnace

1. Introduction

Bogie hearth tempering furnace is mainly to temper the artifacts.

Of which, low temperature tempering is mainly used for various kinds of cutting tools, measuring tools, cold punching mould, bearings and carburized parts that are made of high carbon steel, after tempering the hardness is commonly HRC58-64.

Medium temperature tempering is mainly used for all kinds of springs and hot mould processing, after tempering hardness is commonly HRC35-50 .

Traditionally, we call the combination of high temperature quenching and tempering heat treatment as hardening and tempering treatment, its purpose is to obtain strength, hardness and plasticity, toughness and other better comprehensive mechanical function.

Therefore, it is widely used as the important structural components in automobiles, tractors, machine tools ,such as connecting rod, bolts, gears and shaft .After tempering hardness commonly can be HB200-330.

2. Structures

Consists of furnace shell, furnace lining, furnace door and furnace door lifting device, heating element, trolley and trolley driving device, sealing mechanism,hot air circulation system, electric control system and so on.

3. Features

1). Convenient maintenance

2). Good noise reduction function

3).Seismic resistance performance is good.

4). Trolley uses the sealing structure on both sides

5). Electricity and natural gas both can be the fuel .While, recently, natural gas is popular due to the economy of the operation, protection and energy saving, etc.

6). Hot air circulation system and guiding device is adopted to ensure the temperature uniformity in the furnace chamber.

Bogie hearth tempering furnace is mainly used in the termpering process of steel and special steel, can also be used in heat treatment of solid solution treatment of nonferrous metal, at present our products have already been used for armor plate tempering, special cutting tools tempering treatment etc.
