Description
Technical field
The present invention relates to a kind of expansion force checking device more particularly to a kind of single-side heating type coal coking expansive force detection dresses
It sets and detection method.
Background technique
With being widely used for TAMPING COKING PROCESS, the bulbs of pressure generated in process of coking are increasingly by the weight of people
Depending on coking expansive force appropriate can guarantee coke quality, while expansive force again cannot be excessive, otherwise can generate destruction to furnace wall
Effect.
The prior art mainly adopts the small test coke oven of movable furnace wall structure, structure type is different.As notification number is
The Chinese patent of CN202881174U discloses " testing coke oven that a kind of 40kg can measure the coking coal bulbs of pressure ", including fixation
Furnace wall, mobile furnace wall, frame, sealing system, raw coke oven gas processing system, coke oven heating system, bulbs of pressure acquisition system, briquette
Longitudinal dilatation and degree of shrinkage measuring system.Fixed wall is fixed on base of frame, and mobile wall is mounted on sliding machine, sliding
Dynamic trolley is slidably connected with base of frame, and fixed wall is connect with mobile wall by sealing system.Raw coke oven gas processing unit is mounted on
Frame roof.Its major defect is that coal consumption is big, it usually needs 40kg or more, and since movable wall quality is big, generation rubs
