Description
Technical field
The present invention relates to coal-pressing ball detection technique field, in particular to a kind of coal-pressing ball falling sphere intensity detection system.
Background technique
China Steel yield keeps rapid growth for years, becomes world steel big country.Incident environmental protection is asked
Topic also becomes increasingly conspicuous, and the pollution of trade waste produced by Iron and Steel Enterprises in China influences location periphery increasingly severely
Environment, and start restrict enterprise itself development.To steel-making dust resource recycling, dedusting ash etc. will be made steel and use nodulizer
It is prepared into after raw material ball and enters back into rotary kiln sintered, both reduce environmental pollution, reduce energy consumption, effectively recycled and removed
Iron in dust and slag, while slugging and cooling can also be played the role of.Therefore, pellet has become the main of steel industry
One of feed stock for blast furnace, pellet quality and pellet cost are also the main bottleneck that iron and steel enterprise reduces cost.
After iron ore concentrate or iron content powder, the additive pelletizing on pelletizer generate qualified green pellets, transhipment is fallen to automatically
On belt, and green pellets is transported to dry, roasting apparatus by belt conveyer, and during green pellets transhipment, green pellets is wanted
Occur repeatedly to fall and collide, if production standard is not achieved in green pellets drop strength, green pellets will be caused in drying, roast it
Preceding generation crackle or crushing.A large amount of powder are generated in a large amount of crackles or roasting process so that generating after green pellets roasting, not only
The technological operation for seriously endangering green pellets roasting apparatus, induces various accidents, makes the yield and quality index of operating rate, product
At seriously affecting, and endanger blast furnace operating and direct motion.
In existing pelletizing drop strength detection process, there is no special detection devices, and often producers are with master
The consciousness of sight is fallen from certain altitude, is repeated, until green-ball cracks, and is recorded drop number.Due to not special
The detection device of door, causes in green pellets drop strength detection process that there are following technical problems: green pellets detection process is subjective
Factor is excessive, causes pelletizing drop strength detection inaccuracy, it is difficult to provide the necessary technical support for actual production；In order to enable
Pelletizing drop strength detected value is representative, generally requires to choose multiple green pellets and be detected, and special is set due to no
It is standby, cause green pellets drop strength detection efficiency low, problem above urgent need to resolve.
Summary of the invention
In order to solve the above technical problems, the present invention provides a kind of coal-pressing ball falling sphere intensity detection system, existing to solve
In coal-pressing ball green pellets drop strength detection process, subjectivity is strong, result poor repeatability, drop strength accuracy be not high and
