Abstract
The invention provides a steel billet grinding wheel as well as manufacturing and application thereof. The steel billet grinding wheel consists of a toughened aluminum oxide molten abrasive material or clinkered abrasive material, an adhesive and other auxiliary material, is manufactured by adopting a cold-press and hot-press manufacturing method, and can be used for grinding a steel billet safely and efficiently. The steel billet grinding wheel provided by the invention is high in strength, high in hardness, high in grinding force, relatively high in specificity, capable of realizing a steel billet grinding efficiency which is more than ten times of the grinding efficiency of a common grinding wheel, and capable of greatly improving the work efficiency and the grinding quality.
Description
Technical field
The present invention relates to abrasive tool industry, more particularly, to a kind of preparation method of steel blank regrinding emery wheel.
Background technology
The product made from steel that domestic iron and steel factory produces at present, will carry out reconditioning to billet surface used, remove surface
Impurity and defect, this is the necessary step that improve product quality and yield rate are taken.During plain wheel repairing mill
There is high labor intensive, security is low, the problems such as low production efficiency.It is thus desirable to using new material, new technology is produced replacement and is produced
Product.
Content of the invention
For deficiency in steel blank regrinding for the plain wheel, the invention discloses a kind of preparation side of steel blank regrinding emery wheel
Method, substitutes other conventional abrasive materials by toughness reinforcing aluminum oxide melting or clinkering abrasive material.
In order to realize the purpose of described invention, the present invention adopts the following technical scheme that：
A kind of preparation method of steel blank regrinding emery wheel, each component based on following weight portion for the steel blank regrinding emery wheel is made：

Further, carry out having configured raw material according to raw material, add the raw material in order in double pot batch mixers and mixed
Close；
Further, detect the molding mass mixing, and process is colded pressing and emery wheel blank is made in hot pressing；
Further, emery wheel blank is hardened；
Further, emery wheel is processed into finished product.
Sequential feeds make interiors of products material be evenly distributed, even tissue everywhere, and after solidification, binding ability is more preferable, maximally
Play the effect that between abrasive material, performance is had complementary advantages, give play to the maximum effect of abrasive material, durability.
The present invention melts abrasive material by increasing tougheness aluminum oxide or clinkering abrasive material substitutes other conventional abrasive materials；Made using hot pressing
Grinding wheel, there is high intensity, high rigidity, high grinding degree, the purpose that steel billet is carried out with efficient reconditioning, the present invention reached with this
There is extremely strong specificity, be the decades of times of plain wheel to the grinding efficiency of steel billet, greatly improve operating efficiency and grinding matter
Amount.
