Description
Technical field
The present invention relates to abrading-ball fields, and in particular to is a kind of method of the development abrading-ball intelligent level with controller.
Background technique
Chinese wear-resistant material industrial market scale rapid growth, whole manufacture level are continuously improved.As national economy is steady
Step development, the fields such as China's thermal power generation, metallurgical mine, building material cement also keep steady growth to the demand of wear-resistant ball section
Situation, only domestic wear-resistant ball section reaches 208.74 ten thousand tons in demand 2015, and following table lists 2010-2015, such is produced
The growth pattern of product domestic demand amount:
The country 2010-2015 abrasion-resistant cast abrading-ball section market demand (ten thousand tons)
According to incompletely statistics, in recent years, the export volume of all kinds of wear-resistant ball sections in China year is 1,000,000 ton -150 ten thousand tons.It can
See, though the market demand total amount is larger.
Ball mills quantized level can be divided into four-stage by its development level with the scientific research methods of technology:
1. the trial and error stage；
2. orthogonal experiment method (experimental period, higher cost, and large sample can not be handled)；
3. the exact test method of visual information processing；
4. using Intelligentized Control Model.
Grope the section of third step and the 4th step at abroad, having begun in recent years in abrading-ball manufacture and use field
It grinds method and is formulated with related art method and tool, replenishment of process, manufacture, use and monitor and embody technique " marrow " content
Exquisite device, however it is very different, make slow progress.
At home, it remains in now in the second stage for carrying out scientific research and production application using orthogonal experiment method,
Cause a large amount of dynamic change factors effectively cannot control and predict, product manufacturing and product use long-standing waste
Greatly, low efficiency, problem at high cost cannot solve always；Cannot efficiently use high speed development information technology, automation with
Intellectualized technology accelerates the technological progress in the field, and the pressure for playing scientific and technological effect of taking the lead in race is increasing.And for a long time just
Because domestic abrading-ball manufacturing technology, process equipment fall behind, production technology many decades are constant, think little of refining, and cause steel liquid pure
Cleanliness is poor, and modification effect is unstable, and process of setting has a large amount of segregations, variation and unstable tissue, causes interior tissue will not
Close and surface quality is poor；And mechanical property, the service performance on abrading-ball center portion to surface are inconsistent, directly affect the use of abrading-ball
Service life.Due to by multifactor restriction and interactive effects such as grinding ball material, ball milling equipment, material characteristic, working environments, state so far
Inside and outside research abrading-ball problem is all stuck in the qualitative research stage, energy-saving and reduction production cost to using abrading-ball to generate
Effect is not significant, unstable, in addition excessively relying on experience, causes " awkward situation " that can not be promoted and applied.
In thermal power generation, metallurgical mine, the big industrial circle of building material cement three, numerous ball mills need to be used various for crushing
Mineral aggregate.For a long time, people are to extend the service life of abrading-ball, respectively abrading-ball manufacture and ball mill using abrading-ball the two
The improvement for the experience that the improvement of manufacture experience is carried out in field each independently and abrading-ball uses, though effective, effect is not
Obviously, so that causing great energy consumption, environmental pollution and higher cost greatly lack the competitiveness of product.
The purpose that most economical and performance is able to satisfy the abrading-ball of requirement is produced in order to be supplied to user, inventor is long-pending right for many years
The design and manufacturing experience of abrading-ball have been proposed to State Patent Office entitled " a kind of for ball-grinding machine abrading-ball amount before
Change the method for visualizing of gradation technology ", application No. is the patent applications of " 201610161104X ", a kind of " high abrasion cast grinding ball
The method for visualizing of ingredient design and heat treating regime ", application No. is the patent applications of " 2016101611533 " and a kind of " base
In the cast grinding ball gradation Mathematical Modeling Methods of Visualization Platform ", application No. is the bases of the patent application of " 2016101794163 "
To using abrading-ball, person proposes that a kind of method that development abrading-ball intelligent level matches controller makes the operator of each table grinder on plinth
Science can be reached with controller by using abrading-ball intelligent level, abrading-ball is made to reach best in the ball mill to the greatest extent
Using so that energy-saving to the greatest extent and save the cost indices are realized, thus to solve the above problems.
