A Certain Amount Of Reducing Agent Is Added, And Carbon Is Generally Used As The Reducing Agent. The Reaction Between Carbon And SiO2 Is The Reaction Between Carbon And Impurities: SiO Discharged From The Solution Is Combined With Oxygen In The Air To Form SiO2 (silica Fume). Iron, Titanium Impurities And Silicon Form A Ferrosilicon Alloy Sinking At The Bottom Of The Furnace And Separated From The Zirconium-rich Liquid. Fused Cast Corundum Products Are Attractive For Desilicon Zirconium, Which Improves Product Performance.

At Higher Wheel Speeds, The Metal Removal Rate Can Be Increased, The Grinding Force Can Be Reduced, And The Power Consumption Can Be Reduced. Under The Same Surface Roughness Of The Workpiece, The Grinding Efficiency Can Be Improved. Increasing The Speed Of The CBN Grinding Wheel Will Improve The Surface Roughness Of The Workpiece. The Higher The Grinding Wheel Speed, The Better The Surface Roughness Of The Workpiece, Which Will Reduce The Tangential And Normal Grinding Forces. Grinding Wheel Wear Is Reduced And Grinding Heat Is Reduced.

The Superiority Of Corundum Refractories Is Becoming More And More Important. At The Same Time, Corundum Composite Refractories Have Attracted Attention And Have Developed Rapidly, And The Application Range Is Continuously Expanding. As We All Know, Corundum Has The Advantages Of High Temperature Resistance And Stable Chemical Properties. However, It Has A Large Linear Expansion Coefficient (8.1 × 10 / K), A Large Elastic Modulus, And Poor Thermal Shock Resistance. Therefore, ZrO2 Can Be Added To The Corundum Material Instead Of SiO2, Such As Steel Skateboards.

High Grinding Efficiency Is Required, And Coarse Abrasive Particles Are Used. The Finer The Abrasive Particle Size Is, The Larger The Specific Surface Area Is, The More Dosage Is Needed, And The Fine Abrasive With The Same Porosity Is Softer Than The Coarse Abrasive. In The Same Concentration Of Abrasives, The Hardness Of The Abrasives Increases With The Increase Of The Amount Of Binder. However, If The Combination Dosage Is Too Much, Not Only The Hardness Of The Grinding Tool Will Be Improved Little, But Also The Mixing And Forming Will Be More Difficult.

Lamination Is Mainly Due To The High Thickness (> 20 Mm) Of Solid Rubber. Lamination Method Can Be Divided Into Lamination With Mold And Lamination Without Mold. Then Increase The Roll Distance To Make The Forming Material Automatically Roll Off, Divide It Into Several Parts After Cooling, Press The Blocks Separately, Sprinkle The Talcum Powder, And Park It For Use. The Crosslinking Reaction Is In The Stage Of Thermal Vulcanization, And The Crosslinking Begins To Produce Network Structure. Thereby, The Desiliconization Error Is Obtained By The Enrichment Of ZrO2.

The Forming Pressure Of The Abrasive Formula Is Determined According To The Abrasive Particle Size, Hardness And Organization. Each Formula Has A Fixed Unit Pressure. Only By Pressing According To The Converted Gauge Pressure Can The Quality Of The Product Be Guaranteed. The Pressed Parts Can Achieve The Uniform Density Of The Upper And Lower Structures, Which Ensures The Quality Of The Products. This Can Not Only Overcome The Shortcomings Of Manual Unloading, But Also Ensure The Quality Of The Parts. When The Roughness Value Is Small, Fine Particles Are Used.

At Present, There Are Two Kinds Of Binders Used In Rubber Abrasives In China: Natural Rubber And Synthetic Rubber. The Raw Materials Used For Rubber Abrasive Tools Are Very Complex, And There Are Usually More Than Ten Kinds Of Them, Which Are Generally Divided Into Three Parts, Namely, Abrasive, Rubber And Admixture. The Abrasives Used In Rubber Abrasives Are The Same As Those Used In Ceramic Abrasives And Resin Abrasives, Usually Brown Corundum And White Corundum, With A Small Amount Of Microcrystalline Corundum, Green Silicon Carbide And Black Silicon Carbide.
