A trolley heating (heat treatment) furnace 
 1, furnace structure and function introduction 
 Bogie hearth furnace is a gap-type temperature furnace, the furnace can be divided into the reheating furnace of the trolley and the trolley heat treatment furnace. Stove by the three parts of the mobile station car agencies, furnace, and lift door. 
 2, furnace operating conditions 
 Bogie-hearth furnace with trolley heat treatment furnace main difference between the temperature inside the furnace furnace temperature: 1250 ~ 1300 ℃, Heat Treatment Furnace :650-1150 ℃. Trolley furnace heating fuel is natural gas or coal gas. 
 Recommended wall lining materials and insulation thickness 
 A lining material to determine: 
 According to the temperature inside the furnace gas atmosphere, security, economic and other factors and years of practical experience, furnace lining materials are generally identified as; 
 The furnace roof, furnace wall, the use of containing zirconium fiber prefabricated components, backing fiber castables, high purity or high alumina fiber needle-punched carpet, door and door can be used below with. 
 Heat treatment furnace, roof, furnace walls the use of high purity or high alumina fiber components, the backing can be either standard or high purity fiber Blanket, below the door and the door to the use of fiber castables. 
 B, the thickness of insulation: 
 A variety of industrial furnace wall lining insulation thickness depends mainly on the requirements of the furnace wall outer surface temperature is generally subject to the thermal calculation to determine the minimum insulation thickness, then the security, economic and other factors, ultimately determine the insulation thickness, application experience, combined with many years Taiwan hearth furnace wall lining recommended insulation thickness: 
 Furnace: 280 ~ 350mm 
 Heat treatment furnace: 250 ~ 300mm 
 Recommended wall lining structure: 
 Bogie hearth furnace operating conditions, the recommended wall lining layer Shop, Bonding of composite structures 
 Lining the walls with anchoring structure type in the recommended 
 The fiber component type angle iron ceramic fiber folding block or hanging module can be used to anchor the structure shown in Figure (LYSJ-03 the, LYSJ-01). Material minimum selection 1Cr18Ni9Ti. 
 6, fiber liner installation arranged in the form of 
 The installation of fiber components arranged in the form of recommended along fiber folding Fangxiang Shun arranged in row and the row between the fiber blanket to compensate for the contraction of the folding block components at high temperatures.
