Assembled coal-fired car type heat treatment furnace of "Lineng" brand is consisted of furnace top, control burning system, furnace, car furnace and etc. Its design is novelty and reasonable. The structure is simple, building or reforming is convenient. Furnace top is consisted of chain grate, coal feeding machine, combustion chamber, besides with computer control system, it will be independent intelligent environmental protection coal fired furnace unit. The electric control system may automatically control the furnace temperature, display and record according to preestablished heating, preserving and cooling temperature. The precision of temperature controlling is high, the quality of annealed workpiece is stable. The machine unit is specially suited to reform all kinds of coal fired furnaces. Only two days is for reforming.
The technical performance of reformed furnace is the same as a new furnace. The furnace type can be designed by technology requirement. To design a furnace top pulling one furnace will be for furnace temperature reaching 1000 ºC, a top pulling two furnaces for 800ºC~1000ºC, a top pulling four furnaces for 600ºC~800ºC, a top pulling six furnaces for 400ºC~600ºC. The application of the trolley heat treatment is as following: (1)annealing heat treatment of bearing steel wire; (2)can packing annealing heat treatment of low carbon steel wire; (3)can packing annealing heat treatment of steel belt for welding pipe; (4)annealing heat treatment of great and medium casting; (5)normalizing treatment of work pieces; (6)can packing annealing heat treatment of martensitic iron casting; (7)annealing heat treatment of copper workpiece; (8)annealing heat treatment of steel belt for cable using; (9)drying for sand mould or mud core; (10)drying for alloy or charging material of steel works iron-smelting; Otherwise, Xinke institute may take on design and reform of other type coal fired furnaces.
