Industrial enamel drying equipment and sintering equipment

  Dryers were used in the metal after chemical pretreatment and wet enamelling,although the two devices called dryer,but in the design and operation ,both have great difference: enamel dry machine is from enamel furnace in the electricity, and fuel or gas to heating, actual of heat is infra-red radiation convection; most chemical pretreatment dryer run at higher temperatures,to removed water residues,because drops are hard to evaporate,dry machine also be called dry zone.Enamel dryer removed water from a coated ceramic membrane-lined is carried out in lower temperatures, a very high temperature or a strong air flow may be prematurely drying enamel outer surface of the membrane,and it cause a small amount of water remaining in the inside and cause severe enamel defects.
The company can provide customers with the latest combustion technology in the world today, from Belgium ACOTECH company that creates advanced gas mixed with air by metal fibre combustion technology: efficiency, safety, energy saving, adjusting the heat load from the 100KW/M2-10000KW/M2 range.

  Enamel stove technology:Early furnace is made of refractory bricks, due to the sintering temperature must be between 800 ℃ ~ 850 ℃, but these bricks are very sensitive to thermal shock, and the heating and cooling are very slow; now enamel furnace by low material insulating material, like asbestos, vermiculite and ceramic fibers. Enamel stove using electricity, gas / oil heating, gas and oil are often burned in the radiant tube inside the furnace in order to avoid the enamel coating and internal combustion gases are influences (such as CO2 and H2O).
  Sintering furnace design has a very wide classification, it can be classified as: box-type, intermittent and continuous. Box-type sintering furnace is used in small batch production and small-size products; most of the enameled stove equipped with suspension transporter (intermittent or continuous), in some cases, intermittent hanging conveyor ceramic sintering furnace with automatic doors in order to avoid heat loss. In order to ensure a good and durable enamel coating quality, the smooth curve of the furnace (to avoid thermal shocks) is very important, and only allowed in between the top and bottom with small temperature differences (avoiding chromatic aberration).

Industrial enamel stove, how energy-efficient?
Ceramic sintering furnace is typical of high energy consumption of equipment, because the startup and operation of, they require large quantities of gas, oil, or electricity; enamel furnace the minimum energy consumption depends on: selects the most efficient furnace processes; set the correct stove size; regular preventive maintenance to keep your stove in good condition.
Enamelling stove's energy consumption rates determined by the following: when to enter and leave the stove, the product and the sintering temperature of the tool (heat) from thermal radiation loss in area to the warm heat leakage and the airflow throughout the oven; the conversion efficiency of the heating system; gas/oil furnace, combustion efficiency and exhaust gas temperatures.
Enamel stove environment: to a clean environment for stove is very important to get good results , in the melt phase, high concentrations of CO2 and H2O can slow down the gas through the enamel coating from the base metal emissions, poor and in some cases can cause enamel defects, such as pinhole and scales; therefore, periodic inspection and maintenance of the stove is very necessary.
