No. Of practical new pattern patent: ZL99 2 30121.1

The assembled type coal-fired heat treatment furnace of "Lineng"brand is composed of furnace top, control burning system, furnace tank, car furnace and etc. Its design is novelty and reasonable. The structure is simple, building or reforming the furnace is conveniently. It furnace top is composed by chain grate, loading coal machine, furnace room and etc. Added set of electric control system, the furnace will be unattached intelligent coal burned machine unit of environmental protection. The electric control system may automatically control the furnace temperature, display and record it, according to preestablished temperature of heating, preserving and cooling. 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 burned stove. Only two days is for reforming. The technical performance of reformed furnace is the same as a new furnace. The design of furnace type may decided by technology requirement. To design a furnace top pulling one tank will be for furnace temperature reaching 1000 Degree. C, a top pulling two tanks for 800~1000Degree. C, a top pulling four tanks for 600~800Degree. C, a top pulling six tanks for 400~600Degree. C. The application of the trolley heat treatment is as following:
(1) annealing heat treatment of bearing steel wire;
(2) annealing heat treatment of low carbon steel wire canned;
(3) annealing heat treatment of welding metal strip canned;
(4) annealing heat treatment of great and medium casting;
(5) normalizing treatment of workpiece;
(6) annealing heat treatment of martensitic iron casting canned;
(7) annealing heat treatment of copper workpiece;
(8) annealing heat treatment of steel strip for cable using;
(9) drying for sand mould or loam 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 burned furnace.
