Protective atmosphere mesh belt furnace is a kind of continuous operation furnace, which can complete automatic feeding, pre cleaning, carburizing (quenching), post cleaning, tempering other processes. It is suitable for standard parts industry (wrench, screw driver, pliers, sleeve, Jack, etc.); automobile, motorcycle, bicycle industry; hardware parts industry (pliers, knife, nail, shoe core, nail knife, chain, lock), hook, etc.; thin layer carburizing, carbonitriding, tempering other continuous heat treatment in textile machinery industry.
Structural features of protective atmosphere mesh belt furnace 1. The conveyor belt is made of heat resistant alloy wire. Under the action of stepping transmission mechanism, the furnace bottom supports guide movement to ensure that the mesh belt is in a relaxed state at the main temperature can be improved. The service life smoothness of mesh belt.
The heating of protective atmosphere mesh belt furnace is divided into 9 temperature sections, 9-point temperature control is adopted. The length of the front rear transition zone is 500 mm, the length of 9 zone is 5400 mm, the length of each temperature zone is 600 mm. The set temperature can be adjusted according to the needs. The all fiber energy-saving adopts the furnace lining structure, the heating adopts the ceramic fiber heating plate of 1400 ℃. It has the characteristics of good heat preservation performance, small heat capacity, good uniformity of furnace temperature, fast heating up, energy saving small temperature control lag.
The 1400mm transition zone in front of the furnace is made of 3mm SUS310 heat-resistant steel. An exhaust chimney is designed at 1300 mm in front of the furnace, a regulating valve is designed at the top to regulate the exhaust volume.
The furnace tube in the heating zone is made of 5mm SUS310 heat-resistant stainless steel by folding welding. SUS310 stainless steel has the advantage of high temperature resistance.
The total length of cooling zone is 3200 mm, in which the water cooling section is 1800 mm the natural air cooling length is 1400 mm. The water cooling uses red copper tube wrapped on stainless steel cooling pipe, equipped with water temperature measurement indicator automatic switch for water temperature detection side. Automatic water supply to ensure constant outlet temperature. The cooling furnace tube is made of 3mm SUS310 stainless steel. There is an exhaust chimney at 1300mm between the outlet the inlet, a regulating valve at the upper end to regulate the exhaust volume.
The inlet outlet of the furnace tube are designed to enter the nitrogen curtain up down. The flow rate is adjusted separately. The length of air inlet outlet is 450mm. Control flow. All intake pipes are connected with copper pipes.
