Electric furnace, heating chamber with electricity as the heat source for achieving very high temperatures to melt and alloy metals and refractories. The electricity has no electrochemical effect on the metal but simply heats it. Electric furnaces produce roughly two-fifths of the steel made in the united states. They are used by specialty steelmakers to produce almost all the stainless steels, electrical steels, tool steels, and special alloys required by the chemical, automotive, aircraft, machine-tool, transportation, and food-processing industries. Electric furnaces also are employed, exclusively, by mini-mills, small plants using scrap charges to produce reinforcing bars, merchant bars (e.G., angles and channels), and structural sections. The german-born british inventor sir william siemens first demonstrated the arc furnace in 1879 at the paris exposition by melting iron in crucibles. In this furnace, horizontally placed carbon electrodes produced an electric arc above the container of metal. The first commercial arc furnace in the united states was installed in 1906; it had a capacity of four tons and was equipped with two electrodes. Modern furnaces range in heat size from a few tons up to 400 tons, and the arcs strike directly into the metal bath from vertically positioned, graphite electrodes. Although the three-electrode, three-phase, alternating-current furnace is in general use, single-electrode, direct-current furnaces have been installed more recently.

TL-5 model Indirect burning furnace with 5 layers sleeves consists of 5 parts: a blower, flue gas induced draft fan, burner, five-layer sleeve body and control system. The flue gas in the furnace takes two rounds while the fresh air takes three rounds. Natural gas is burned through the burner to generate a high-temperature flame. Under the action of the flue gas fan, the heat is transferred to the heated air through the five-layer sleeve wall and dense fins, meanwhile the flue gas is discharging out the body after it´s temperature down to 150. The heated fresh air enter the sleeves through blower. After heat mix, the temperature rises to the setting number and sent out from the hot air outlet. 4ã??Advantages/features 1. Continuously provide pure air with constant temperature and constant pressure. 2. Temperature has a wide adjustable range: 40~300 3. Indirect heating, automatic operation, exhaust gas emissions meet the requirements 4. Reasonable design, compact structure, thermal efficiency up to 75% 5. Stainless steel high temperature resistant inner tank, durable
TL-4 model Direct burning furnace with 3 layers sleeve consists of 3 layers of cylinders. It uses fully burned natural gas to obtain high-temperature flame, and mixing this temperature with fresh air to achieve the required hot air device. Due to the use of fully automatic single-stage fire, two-stage fire or modulating burner, the output hot air is extremely clean by natural gas fully burned, , meeting the drying and dehydration needs for most stuffs. The external fresh air enter the furnace body under negative pressure, takes two strokes and sequentially cools the middle cylinder and the inner tank. After being fully mixed with the high-temperature flame in the mixing zone, it is extracted from the furnace body and enter the drying room. When the temperature reach the setting number, the main burner stops working and the auxiliary burner continues to burn to maintain the temperature. When the temperature drops to the set lower limit temperature, the main burner will be run again. 4ã??Advantages/features 1. Simple structure and easy installation 2. Small air volume, high temperature, adjustable from normal temperature to 500â?? 3. Stainless steel high temperature resistant inner tank, durable 4. Automatic gas burner, complete combustion, high efficiency. (After setting up, the system can control the ignition+cease fire+temperature adjust automatic), 5.

It is specially designed for supporting downflow drying room/heating rooms. After fully combusts the natural gas inside the inner tank, it�´s mixed with recycle or fresh air, under the action of the fan, it is discharged from the upper outlet into the drying room or heating space. Then cooled air pass through the lower air outlet for secondary heating and continuous circulation. And when the humidity of circulating air reaches the emission standard, the dehumidification fan and fresh air damper will start simultaneously. The exhausted moisture and fresh air implement sufficient heat exchange in the waste heat recovery device, so the moisture is discharged and the fresh air with recovered heat enter the circulation system. 4.

It is specially designed to support the left and right circulation drying room. For example, the 100,000 kcal model drying room, it is equipped with 6 fans, three on the left and three on the right. When the three fans on the left rotate clockwise, the three fans on the right rotate counterclockwise in a cyclic alternating manner, forming a relay, The left and right sides serve as air inlets and outlets alternately, taking out all the heat generated by full combustion of natural gas. It is equipped with an electric fresh air damper to supplement fresh air in coordination with the dehumidification system in the drying room/drying place. 4. Advantages/features 1.

Automatically replenish fresh air
TL-1 burning furnace is consists of 5 parts: natural gas burner + inner tank + insulation box + fan + control system. The burner forms a high-temperature flame after full combustion in the high-temperature resistant inner tank, these flame mixes with the cold or recirculated air to produce a new and high-temperature air. Under the action of the fan, it is discharged to provide heating for drying machines or places. Advantages/features 1. Simple structure and low cost 2.
