Iron-based sintering furnace
First, the main parameters of iron-based sintering furnace:
1, rated temperature: 1150 ℃
2, net width: 270mm
3, heating power: 85KW
4, with the network speed: 30-150mm / min
5, temperature control accuracy: ± 5 ℃
6, gas consumption protection: ≤ 12m3 / h (3H2 + N2 flow meter)
7, product through the height: ≤ 100mm
Second, the main structure of iron-based sintering furnace and other requirements:
1, The equipment is mainly composed of feeding section, preheating section, sintering section, water cooling section, mesh belt and driving device, electric control device for several parts.
2, the top of the furnace is arched, the material is 310S, 8mm, the total length of the furnace is 16790mm; the effective size of the cross section of the furnace tube of the sintering section is 270 × 100mm; the length of the body tube is 5180mm; the material of the furnace tube is SUS310S / δ = 8mm.
3, the net string wire material SUS314S / Φ4mm, wire material SUS314S / Φ3mm, welding edge.
4, Belt drive with multiple corrective devices, the use of frequency control, and with a digital network with speed measuring device.
5, water-cooled tube material for the SUS304S / δ = 4mm, water jacket material is 304 / δ = 4mm. Water-cooled section is divided into three sections of independent, about 6000mm long, open water jacket structure, low cooling water, water pipe diameter 4 points, water pipe diameter 6 points.
6, the discharge furnace tube curtain to prevent the infiltration of external gas furnace tube.
7, heating elements arranged in the upper and lower furnace tube, left or right sides of the structure, easy maintenance and replacement.
8, the heating element is made of orc27AIMO2
9, the bricks are high quality aluminum refractory material contact.
10,2 preheating zone, high temperature sintering zone for the four heating zones, each zone is equipped with a set of thermocouple, digital display intelligent regulator and silicon PID closed-loop temperature control system.
11, the furnace shell adopts the upper part of the easy-detachable mechanism to facilitate the repair and replacement of the furnace tube, the device looks nice, the paint colors of each part are:
Furnace: bright silver white
Electric control cabinet: light green
12, set two air inlet in the sintering furnace tube out of the material end, the air inlet at the baffle, two air inlet at the same time to protect the atmosphere, but also through a protective atmosphere, a pass of nitrogen. One end of the water-cooled section near the outlet is provided with a protective gas inlet (for example, an atmosphere). The inlet and outlet are respectively protected by N2 and H2, and the needle-shaped regulating valve and the glass rotor flowmeter are arranged at the inlet end of the protective gas. Four flow meters and control valve installed in the same place, for easy operation.
13, at the same time with a network speed, cooling water temperature alarm and other functions.
14, the lining of high-quality custom-made high-alumina refractory brick, high-quality fire-resistant insulation and aluminum silicate fiber mat and fiber composition.
