CONTINUOUS FURNACE FOR CARBURIZING, HARDENING AND TEMPERING

 

CONVEYOR FURNACES FOR FASTENERS


Application of heat treatment equipment

A conveyor furnace is an industrial furnace in which the product moves from the loading station to unloading on a conveyor. Continuous conveyor furnaces can perform a variety of heat treatment processes, such as cementation, carbonitriding, tempering screws, nuts, bicycle parts, hand tools, hardening of mechanical parts of automotive accessories, fasteners, chains, bearings, tools and other products and ending with a sharp cooling in oil or water, polymers and salts.

  • Carburizing and hardening of metal products: self-tapping screws, self-drilling screws, wood screws.
  • Hardening of fasteners (bolts, nuts).
  • Thermal processing of bicycle parts, motorcycles, cars.
  • Heat treatment of hand tools

 

GAS HEATING TYPE or ELECTRICAL HEATING TYPE ?

Before selecting a continuous furnace for heat treatment of metal products it is necessary to pre-determine for yourselves the type of heating furnace. Furnaces are of two types: electric and gas heating furnace. To calculate the cost of production is strongly recommended to study the table which shows the calculation of the cost of running the continuous furnace line (Taiwan).

ONE WHOLE-SET OF CONTINUOUS BRIGHT CARBURIZING (HARDENING) QUENCHING FURNACE (BY GAS BURNER SYSTEM)

One whole-set of continuous bright carburizing (hardening) quenching furnace (by gas burner system), model RG, for heat treatment (hardening + carburizing and high tempering) of fasteners (allpurpose screws, nuts and special products) in protective atmosphere.

One whole-set of continuous hardening quenching furnace for heat treatment of fasteners


Features of hardening and tempering furnaces with gas heating:

gas
  • Used in fasteners industries, automobile, motorcycle, bicycle parts industries, chains industries, concrete nails industries, hand-tools industries, hardware industries, stationery industries, forging parts industries, aerospace industries and commercial heat-treatment industries, ect.
  • The gas burner is made on the basis of US technology. Exhaust air is removed through the exhaust pipe. The special design of double pipe maintains a uniform temperature. 60% of the heat carried in the heat exchanger.
  • The radiation tube is made of heat-resistant centrifugal cast pipe according to Japanese production technology with small deformation, and increased service life.
  • Gas heating system saves energy costs.
  • The heating process is much faster than when heated by electricity. The oven is ideal for mass production.
