3-5 Ton Tilting Rottary Furnance Production Line

3-5 ton tilting rottary furnance

2.1,Energy-saving high-temperature heat recovery burner

Adopt a 260X104Kcal / h high-temperature heat recovery burner (burner with automatic ignition, automatic air supply gas, automatic fire size adjustment function), high temperature heat recovery LOT burner using German technology, the heat exchange area twice the normal storage hot burner, capable of cold combustion air blower blown rapidly heated to 850-1000 ℃, saving 30-40% energy saving effect compared to ordinary burner, compared to ordinary regenerative burners saving 10-15%; to achieve 4t / h melting rate (without addition) and energy , 60m3 / t.AL in the case of continuous production.

2.2,Steel shell

Smelting furnace steel with fully welded construction, rectangular furnace wall panels using 8mm thick high-quality Q235 steel plate (bottom with a 10mm thick high-quality Q235 steel plate) and 120-160 # channel steel welded together, the entire housing forms a mesh reinforcing steel, the steel structure with good strength and air tightness; sufficiently withstand the mechanical and thermal stresses furnace

2.3,Furnace door system

Setting an electric smelting furnace lift door in the side of the slag plus materials, smelting furnace space 2000x1400mm (straight inch opening can be adjusted according to user requirements); large door in addition to convenient truck or feeder feeding, but also no slag dead! Door surrounded by a heat-resistant cast iron block (RQTSi5) assembled into a whole, door plus lined with castable anchor hook made of cast, anti-thermal expansion and contraction capabilities. A heat-resistant cast iron stove door (RQTSi5) made the connection block on the stove and bolted steel structure, easy maintenance (also burned piece piece). All heat-resistant cast iron parts are machined toensure dimensional accuracy so that can form a good seal between the door and the oven door.

2.4,hoods smoke collection

To collect harmful gases generated during the refining side to shop outside (or into environmental protection equipment); to ensure the workshop working environment; hoods use δ5mm Q235 steel, lined with thick fiberboard δ15mm ensure that the door opens and more the surface of the refining process will not produce high temperature paint does not come off of the case

2.5, Temperature control system

A, smelting furnace turn on the water near the mouth of the furnace wall close to the work floor installed a thermocouple temperature measurement through the active layer as the reference value;

B, smelting furnace roof to install a stationary furnace thermocouple to detect the temperature of the furnace;

C, thermocouples are used silicon carbide outer protective sleeve material, thermal shock resistance and good! long life!

2.6,Furnace pressure control system

A, the top of the stove with a differential pressure transmitter, its output signal to the PLC, PID operation, then control the electric control valve opening size of the exhaust fan in front by controlling exhaust emissions to achieve slightly positive furnace control.

B, by adjusting the flame shape, flame exit velocity control, the amount of combustion air ratio of effective supply, a reasonable set of exhaust pipe of a number of measures to better our company to achieve effective control of furnace pressure, furnace pressure to solve the high, mouth sparkle problem, the actual furnace pressure control ensures that the range within ± 100Pa.

2.7,Automatic control and display

Full use of the stove and touch screen PLC automatic control, and a comprehensive fault alarm function, reduce labor intensity and randomness manually operated; 

2.8,Oven walls and roof

Melting furnace lining layer is made using high alumina brick work brickwork; flat-topped roof using prefabricated structures, combined with stainless steel anchor bricks and reinforced grab.
