It closes.
Embodiment one
Fig. 1 is a kind of stream for the method that ring formation of rotary kiln situation is predicted by green-ball surface quality in the embodiment of the present invention
Journey schematic diagram, as shown in Figure 1, which comprises
Step 110: obtaining Iron Ore Powder fineness number；
Step 120: obtaining the anti-wear index of pre- hot-bulb；
Step 130: according to the anti-wear index of the Iron Ore Powder fineness number and the pre- hot-bulb, obtaining green-ball surface matter
Volume index；
Step 140: according to the green-ball surface quality index, predicting ring formation of rotary kiln situation.
Specifically, keeping stable item in rotary kiln thermal regulation for grate-kiln pelletizing technique
Under part, the quality of green-ball surface quality directly affects the ring formation problem of rotary kiln.If green-ball surface quality is good, smoother, then
In transhipment, cloth and rotary kiln in rotation process, for the powder of generation with regard to less, such rotary kiln is just not easy ring formation, ball
Group's production can be carried out along steady；If green-ball quality control on the surface is bad, rough surface, then the powder generated may build up
Low melting point is formed in rotary kiln, causes a large amount of ring formation substances, to influence the normal production of pelletizing, therefore, the present invention is real
It applies example and predicts ring formation of rotary kiln situation by green-ball surface quality, wherein green-ball surface quality is by calculating green-ball surface
Performance figure determines, wherein the green-ball surface quality index is used to characterize green-ball surface roughness and wear-resistant degree
One composite index, what is measured is under grate kiln process flow, and green-ball is turning round after drying and preheating
Anti-friction ability in kiln Jing Guo phase mutual friction.The numberical range of the green-ball surface quality index is between 0~1, numerical value
Bigger, the green-ball surface quality is better, and the ring formation degree of rotary kiln is smaller, and the numerical value of the green-ball surface quality index is got over
Small, the green-ball surface quality is poorer, and the ring formation degree of rotary kiln is more serious.Since green-ball surface quality includes two fingers
Mark, is Static State Index and dynamic indicator respectively, wherein the Static State Index is obtained by Iron Ore Powder fineness number, described dynamic
State index uses the anti-wear index of pre- hot-bulb, therefore calculates the specific steps of the green-ball surface quality index are as follows: obtains first
Iron Ore Powder fineness number, wherein the average grain diameter of the Iron Ore Powder is bigger, then green-ball surface quality is poorer；Pre- hot-bulb is obtained again
Anti-wear index, wherein the anti-wear index of the pre- hot-bulb refers to through certain measurement method, measures green-ball by certain
Pre- hot-bulb anti-wear index after preheating temperature, what it is for characterization is that the green-ball enters revolution after drying grate drying, preheating
Kiln, due to mutual frictional impact generate powder the case where, the anti-wear index of the pre- hot-bulb is higher, then green-ball surface matter
Amount is better；Then it according to the anti-wear index of the Iron Ore Powder fineness number and the pre- hot-bulb, obtains green-ball surface quality and refers to
Number, since the green-ball surface quality index is used to characterize the quality of green-ball surface quality, further in rotary kiln thermal regulation
It keeps under conditions of stablizing, predicts the situation of ring formation of rotary kiln, by the calculating of the green-ball surface quality index to adopt
It takes measure to improve quality of green pellets, the ring formation degree of rotary kiln is effectively reduced, then push away by the way that the ring formation of rotary kiln state is counter, protect
Hindered going on smoothly for pelletizing production, realize it is simple from the angle of green-ball surface quality for the first time, directly, can be quantitatively to returning
The ring formation situation of rotary kiln is predicted.
In step 110, the Iron Ore Powder fineness number can calculate according to the following formula acquisition:
Wherein, D=∑ Xi×di,XiBe partial size be diIron Ore Powder mass percent, the average grain of the Iron Ore Powder
Diameter is bigger, then green-ball surface quality is poorer, and the average grain diameter of the Iron Ore Powder is smaller, then green-ball surface quality is better.
In the step 120, the anti-wear index for obtaining pre- hot-bulb, comprising: original dry bulb is put into anti-wear index measurement
In device, wherein the original dry bulb is the green-ball being completely dried by 100 DEG C, quality M0, then turned with certain speed
Dynamic 15~25min, the original dry bulb generates powder because of phase mutual friction in the anti-wear index measuring device, to obtain
Dry bulb after must rubbing, the dry bulb mass M after measuring the friction1；Calculate the mass M of dry bulb after the friction1With the original
The mass M of beginning dry bulb0Percentage, to obtain the anti-wear index of the pre- hot-bulb, specifically, the pre- hot-bulb it is wear-resistant
The calculation formula of index are as follows:
QD=10 (K-0.9),
Wherein, K=(M1/M0) * 100%, K be the dry bulb anti-wear index；
M1For the dry bulb quality after the friction；
M0For the original dry bulb quality.
In step 130, the anti-wear index according to the Iron Ore Powder fineness number and the pre- hot-bulb, is given birth to
Ball surface quality index, the calculation formula of the green-ball surface quality index are as follows:
Q=0.5QS+0.5QD
Wherein, QSFor Iron Ore Powder fineness number；QDFor the anti-wear index of pre- hot-bulb.
