砂轮片生产用棕刚玉马克砂F46#Brown aluminum oxide

倾倒炉棕刚玉砂是由倾倒法生产的棕刚玉为原料，经巴马克制砂线破碎筛分而来的棕刚玉砂。不同于熔块法生产的棕刚玉，倾倒炉棕刚玉的氧化铝纯度高，杂质少，韧性和自锐性优异，颜色比固定炉棕刚玉颜色深。倾倒炉棕刚玉通常不采用对辊和球磨制砂，而是为了满足磨具制品对堆积密度的要求，采用巴马克制砂机进行生产，得到堆积密度高、粒型相对圆整的棕刚玉磨料。因此，巴马克倾倒炉棕刚玉适用于陶瓷砂轮、重负荷砂轮、打磨片等固结磨具的生产，生产的磨具制品具有发热量低、减少砂轮对金属的烧伤、提高砂轮锋利度、裂纹废品率低的特点。

Brown fused alumina grit is a basic abrasive grain for making abrasive tools and abrasive blasting. It is produced from natural bauxite mine by a fusing process. After fusing and melting at about 2000 centigrade, it turns to a kind of artificial brown fused alumina. The main chemical of brown fused alumina is Al2O3. So it also be called brown aluminum oxide.

With different milling technology, there are several types of brown fused alumina. They are available for different applications such as sandblasting, resin bonded abrasives, vitrified bonded abrasives,anti-skid materials,etc.

砂轮片生产用棕刚玉马克砂F46#Brown aluminum oxide的特点：

1.氧化铝含量高，硅、铁等杂质含量低，磁性物含量低，钛含量适中。

2.冶炼更充分，致密性高，晶体尺寸比固定炉小，因而自锐性更好。

3. 磨料颗粒尖角少，圆整度高，单位体积的堆积密度高，同等尺寸的砂轮中参与磨削的磨料多，可提高砂轮的使用时间。

4. 特殊的制砂工艺，使棕刚玉磨粒中的裂纹数量控制在一定范围内，经过高温烧制做成砂轮不易产生哑声、裂纹等缺陷。

Features of brown fused aluminum oxide:

1.High hardness around Mohs 9.0.

2.High toughness which is a little higher than white fused alumina.

3.Good grinding ability.

4.A quality level with high Al2O3 purity and low TiO2 impurity.

5.Low Fe2O3 content with magnetic removal treatment.

6.Good grain shape with higher bulk density.
