1. Full fiber large trolley furnace Purpose:

 

The RT3-180-9 full fiber cotton trolley type resistance furnace is a periodic operation furnace mainly used for heat treatment (normalizing, annealing) of general large and medium-sized metal or alloy parts at temperatures below the rated temperature. This electric furnace is specially designed for users to match the heating treatment of ring components.

 

2. Technical parameters of full fiber large trolley furnace;

 

(1) Rated power: 180kw ± 10%; 240kw±10%

 

(2) Rated voltage: 380v

 

(3) Number of phases: 3 phases

 

(4) Frequency: 50Hz

 

(5) Rated temperature: 950 ℃

 

(6) Number of temperature control zones: Zone 2

 

(7) Furnace temperature uniformity: ≤ ± 10 ℃

 

(8) Empty furnace heating time: ≤ 2h (full fiber type)

 

≤ 3.5h (brick type)

 

(9) Effective workspace size (length × wide × High: 4200 × nine hundred × 7500mm

 

three thousand and four hundred × one thousand three hundred and fifty × 950㎜

 

(10) Temperature control accuracy: ≤ 2 ℃

 

(11) Temperature control method: thyristor pid adjustment, Shanghai Dahua multi-point recorder

 

3. Introduction to the structure of a large all fiber trolley furnace:

 

(1) This trolley furnace consists of a furnace body and a movable trolley.

 

(2) The furnace shell and trolley are welded with high-quality steel plates and profiles.

 

(3) The heating element is arranged on the furnace side using the high resistance alloy cr25al5 resistance strip produced by Shougang, and the cr25al5 resistance wire is arranged on the trolley.

 

(4) The furnace lining is made of pure fiber cotton, and the load-bearing part is built with heavy refractory bricks to enhance the structural strength of the furnace lining. The insulation layer of the trolley adopts a composite structure of aluminum silicate refractory fiber and diatomaceous earth insulation brick to improve the insulation performance of the furnace body.
