heating furnace

◆ is mainly used for heating the blank before rolling;
◆ adopt patent multi-strand jet structure, flame dispersion combustion technology;
◆ heating quality is good, the temperature difference between section and length direction of billet is small.
◆ only upper heating, generally used for the thickness of 150 mm below the blank heating;
The ◆ adopts P-HTAC control technology, adopts the PLC HMI distributed control system, the temperature control is accurate, the combustion is more sufficient, and effectively reduces the oxidation burning loss;
◆ high efficiency heat storage honeycomb structure design, small size, simple and compact structure, more than double the efficiency of conventional heat storage;
◆ furnace bottom is made of refractory material, no water cooling, energy saving, safety, longevity;
The unit consumption of ◆ natural gas <40 m³/t, adopts double heat storage of air and gas to realize ultimate preheating recovery;
◆ can use blast furnace gas, hot dirty gas, mixed gas, natural gas, liquefied gas, generator gas and other gas fuels;
◆ use pulse combustion instead of proportional combustion, especially in low yield or heat preservation can maintain a stable flame length, so that the furnace cross-section temperature to maintain uniform;
◆ high efficiency heat storage honeycomb structure design, small size, simple and compact structure, more than double the efficiency of conventional heat storage;
◆ multi-strand jet structure, no flue gas high-speed erosion, no local high temperature, honeycomb life up to 18 months;
◆ medium preheating temperature and inlet flue gas temperature difference less than 100℃, limit recovery of flue gas waste heat;
◆ low oxygen volume dispersion combustion, low NOx combustion, furnace temperature more uniform;
◆ comply with the Industrial Furnace and Kiln Air Pollutant Emission Standards (GB9078-1996);
◆ pneumatic reversing valve, simple structure, stable and reliable operation, life up to 1.5 million times;
◆ adopt castable whole furnace top and compound layer furnace wall structure to reduce heat loss of furnace body;
◆ oxidation loss is controlled below 1.0%, the calorific value of gas is measured by on-line calorimeter, and the air-fuel ratio is controlled;

 ◆ all automatic controls are equipped with advanced, reliable and perfect three-electric integrated automatic control system, the heating furnace can realize manual, semi-automatic, automatic operation and material tracking
