Product features This furnace is designed as special equipment for electric insulation of aluminum alloy machine edges . Imported non - stick aluminum castable is poured into a pool type , i . e . no crucible is needed . It has the advantages of long service life , strong heating capacity , low surface temperature , low energy consumption , convenient operation , etc . The design of this furnace is based on the concept of user - centered and practical operation . The internal structure of the furnace is made of imported castable as lining , impermeable layer , imported nano micropate and ceramic fiber board as thermal insulation materials . The minimum holding temperature is adopted as the standard in size design to meet the requirements of customers for aluminum soup , so as to ensure the service life of the furnace and effectively reduce the heat loss on the surface . It is a kind of high - performance aluminum alloy special electric heat preservation furnace with international advanced level and energy consumption pursuing energy conservation to the
limit .
Description of furnace body structure
The main body shell components :
1. The outer body and bottom plate are welded together with 8mmA3 steel plate , and the bottom frame welded
together with 10# national standard channel steel is basically of metal welding structure except for the internal thermal insulation layer and working layer .
2. The four supporting legs of the base are made of liftable threaded columns , which can reach the required height by adjusting nuts ( which can be made according to customer ' s requirements ). Lining structure in furnace body
The inner lining of the furnace body consists of an outer shel iron plate , a heat screen coating , a calcium silicate
plate , a ceramic fiber board + nano microplate plate , an aluminum liquid water - proof permeation prevention layer , a pouring layer and a pouring layer in sequence from the outside to the inside . The pouring layer is formed by pouring imported non - stick aluminum pouring materials in two parts , and the separated parts are connected in a C - shaped groove ype connection , so that expansion and contraction of each part of the furnace do not affect each other , unreasonable cracks caused by thermal expansion of the furnace are reduced , and the service life of the furnace is prolonged . In the aspect of heat preservation , the bricks are arranged in a certain sequence through heat conduction calculation , so that the surface temperature of the heat preservation furnace is kept below room temperature +30 DEG C , the high - temperature working environment of the workshop is improved , the energy consumption is further reduced , and the competitiveness of products is improved . Under normal use conditions , the service life is over 3years. Furnace cover structure
The furnace cover is lined with ceramic fiber board , nano microplate and castable , and ceramic protection tubes are embedded in the positions where the heating wires are instaled , thus preventing the possibility of damaging the insulation layer by replacing the heating wires . The long - term use temperature of 1100 degrees ensures the service life of the furnace cover .
