Natural gas aluminum melting furnace

The key structure characters of round fast energy conservation melting aluminum furnace are as follows: 1.Applying round bottom stove and rational burning equipment:strong stove gas circulation ,stove temperature well-distributed ,no partial over-heated phenomenon,improving product quality ,prolong the stove’s life-span.Meanwhile the flame is far away from melting materials ,burning damage is low(and melting materials is more),and the lowest burning damage is below 1.0 percent. 2.applying vertical stove:melting materials are fully absorbed the smoke and left heat,making the draining smoke temperature of the stove above drops to 150°C below,and it improves heat efficiency largely.The hightest melting apeed can get to 1.5h/stove,and the lowest consume reaches to 36×10 4kcal/t.While most melting materials enter into aluminum liquid then smelt ,it reduces the touching area of aluminum liquid and stove gas ,lowering burning damage . 3.applying air preheating equipment and stove shell intercalary wind pipe,when entering temperature rising and keeping process,rthere is no melting materials in vertical stove.Then air preheating equipment can absorb the smoke and left heat.the air after preheated enters the stove shell intercalary wind pipe,the pipe which is in the heat preservation layer of whose temperature relatively ,and lessens the dispersing,flame temperature and speed .It strongthens the circulation of gas and temperature 's rising speed. 4.The structure of the stove door is reasonable :stove door needs ni materials adding,so the door is small and sealed up tensely,opening time less,heat diepering little,no pushing aside leaving’s corner ,convenient operate and good operating envitonment. Adding materials above the stove:convenient adding,low labour strengh,temperature changing little,stove age old,no taking up the melting time while adding materials. 5.Using high efficiency spare burning machine as the heating resource; 6. It has characters of easy firing,fast rising temperature ,high erupting speed,fully burning and the coefficient of over air is little.
