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.
