Cooling mechanism
In general, the cooling state (organization tumover happens in cooling procedure) of steel
wire in water can be described as 3 states:
- Nuclear boiling: water direct contacts with metal surface and furious boiling occurs, a large
number of bubbles are generated, intense liquid convection cooling accompanies in the meantime.
- Film boiling: all water surrounding metal gasifies, and forms a steam membrane to cover
whole steel wire, metal heat emits via heat conduction and heat radiation inside the membrane, as
well as flow of fluid surrounding steam membrane. Because metal and water is insulated by steam
membrane, metal cooling speed drops rapidly. The more stable steam membrane is, the thicker
the membrane is, and the slower the cooling speed is. Along with thickening of steam membrane,
small and homogeneous bubbles are generated by surface tension escape from water.
- Convective heat transfer: because temperature of metal surface is lower than temperature
of water boiling, so natural convective heat dissipation happens by temperature difference. Steel
wire dips into water at Ac3 or Acm temperature and starts cooling from nuclear boiling state, and
soon enters into film boiling state, then returns to nuclear boiling state along with temperature
drops (because steam pressure inside membrane cannot maintain stabilization of membrane), and
finally enters into Convective heat transfer state;
Natural Gas Furnace
Material: Carbon Wire. DV: 50-120 mm.m/min. Wire diameter: Ø0.8-13.0 mm. Wire number: Based on design
The N.G. furnace is about 27 meters, and each heating section is relatively
independent and influenced each other. According to the requirements of heat treatment
process, the furnace temperature and atmosphere can be set up in order to meet the process
requirements.
The furnace body is divided into five heating sections, and each section separately
controls the temperature and regulates the atmosphere. The pre-mixed gas heating
technology of Belgium FIB company was selected, and several FIB type premix burners
were installed in each heating section.
Each heating section is calculated and adjusted by the temperature regulator
according to the actual measurement and setting. Combustion control system by the Belgian FIB
company introduction of digestion and absorption of technology, when gas stable quality
can to control the temperature difference between + 3°C or less.
The system
has the function of constant air-fuel ratio, which can accurately control the atmosphere
in each section of the furnace. At the same time, the combination of a variety of control
means makes the pressure in the furnace controlled in the normal range, eliminating the
oxidation of steel wire caused by the air inhaled in the furnace.
