Checking method for discharging hopper scale of blast furnace chute

Abstract

The invention discloses a checking method for a discharging hopper scale of a blast furnace chute. The checking method comprises the following steps: checking precision and accuracy of a first intermediate hopper balance by using a chain code; finishing checking of a weighing hopper balance by taking the intermediate hopper balance as a standard hopper balance; finishing checking of other intermediate hopper balances by taking the checked weighing hopper balance as the standard hopper balance. According to the method, except that the checking of the first intermediate hopper balance needs to be performed in a batching operation gap, checking of other hopper balances can be performed in a batching operation process, production requirements on synchronization of discharging, batching and checking of the blast furnace chute are met, the effective operation efficiency of a blast furnace is improved, and the checking speed of the hopper balances is also improved. Besides, the chain code canmeet load standards of the checking and occupancy of the chain code can be adjusted. Therefore, the first intermediate hopper balance checked by adopting the chain code has higher precision and accuracy. Correspondingly, other hopper balances taking the first intermediate hopper balance as the standard hopper balance also have higher precision and accuracy.

Description

technical field [0001] The present application relates to the technical field of blast furnace production, in particular to a checking method for a hopper scale under a blast furnace tank. Background technique [0002] figure 1 It is a schematic diagram of the structure of the batching system under the tank, such as figure 1 As shown, in blast furnace production, the batching system under the trough mainly includes silo 1, feeder 2, vibrating screen 3, weighing hopper 4, belt conveyor 5, intermediate hopper 6 and feed truck 7. When batching, each bunker 1 places a kind of raw material required for the blast furnace, such as sintered ore, coke, pellets, solvent, etc. A weighing hopper 4 is arranged under each silo 1. After being weighed by the weighing hopper 4, the raw materials entering the furnace in the silo 1 enter the middle hopper 6 through the conveyor belt of the belt conveyor 5 and are mixed in the middle hopper 6. , After weighing, enter the feeder car 7, and fi...
