Fiber trolley furnace

Fiber trolley furnace uses:
Fiber trolley furnace is mainly used for high temperature annealing and normalizing of the metal member, can also be used a variety of heating of the metal or metalloid in the 1000 ° C or less.
All-fiber trolley heating furnace body structure:
Fiber trolley furnace furnace is mainly composed of steel plate and steel welded steel plate thickness of 5 mm, using the steel skeleton to strengthen, with sufficient strength and stiffness, installed on the roof two temperature thermocouple seat to ensure thermoelectric even inserted inside the furnace temperature. In front of the furnace furnace panel and door are heat-resistant cast iron, has a heat distortion characteristics of a small, consider workpiece normalizing, trolleys pull out the workpiece, the workpiece with a high temperature, the choice of door and the furnace panel of heat-resistant castings to prevent the deformation of the door and the furnace panel in the hot state.
Fiber trolley furnace heating elements:
Fiber trolley furnace heating element used Shougang Gitane alloy produced resistance band, made 0Cr25AL5A heating element is divided into two areas, located in the side wall of the furnace and the trolley, the heating element is wound into a zigzag , Y connection, after the trolley heating element wiring using plug knife wiring structure, the heating element 2-zone temperature control, power arrangement give full consideration to the door of the heat loss characteristics, in both sides of the wall and station car The front area design appropriate to increase the power to reduce the heat loss of the door. The heating element is hung on both sides of the furnace, the heating element and the furnace bottom of the trolley to leave a certain distance, to prevent the heating element and the furnace bottom short.
All-fiber trolley furnace lining structure
The all-fiber trolley furnace lining all-fiber structure. Selection of high-alumina fiber folding block full fiber structure is mainly distributed in the side wall of the furnace, the front wall, back wall, roof and door hanging fiber roof, made of fire-resistant fiber folding block module buried anchors hanging out the folding module on the top of the expansion of the left between each line module to prevent thermal expansion and contraction of the module. The roof structure of the flat-topped, energy saving, reduce wasted space, and compact structure. On both sides of the furnace wall, front wall, back wall and door are made of fire-resistant fiber folding block, folded pieces of buried anchors. The side wall of the furnace back wall and door folding block in addition to buried anchors, buried pieces of porcelain and support staff fixed heating element to fall hanging heating element. This structure in Shandong bright steel forging factory, Dalian Locomotive Works cast steel branch, Datong Locomotive Works heat treatment branch in Dalian Locomotive Works heat treatment factory large trolley furnace use, very good results have been used in the past two years without any quality problems. Trolley lining material mainly consider the carrying capacity of the refractory layer selection of heavy high alumina bricks, insulation choice of thermal conductivity of 0.6 kcal / m. Degrees lightweight insulation tiles.
