High-temperature Bonding Agent

The high-temperature bonding agent manufactured by our company is divided into two categories, that is, air hardening and thermal hardening, and the every material has light and heavy quality. Based on requirements of masonry product materials, it is required to select and use the high-temperature binder with corresponding material quality. This binder is characterized by high binding strength, good erosion resistance, small masonry mortar joint, good massive structure of masonry and convenient construction.

Recycling of Refractory Materials

     In a word: Recycle the refractory materials by decomposing them.

    The type of refractory materials used in a furnace differs by the position. All kinds of used refractories mixed together make it hard to keep good quality, so it is necessary to classify refractories before reusing them. They can be classified by magnesia, alumina, carbon-based, non-carbon-based.

In addition, for the dissimilar materials  or iron mixed in, we can use some ways to pick them out, such as the method of magnetic separation. First, the used refractory materials should be crushed to 200mm~ 400mm, and then reduce to smaller than 20mm after impacting, compression or snipping, so as to be easy used.

For the refractories mixed with iron, we can use the way of electromagnetic separation, on the effect of magnetic strength higher than 12000 GS, making the content of iron in the used refractories with the size of 5~10mm less than 2%. While reusing the slit after crushing and after removal of iron powder as raw materials, we should classify them by particle size. The classification is generally done by using some metal mesh sieves, put the large mesh screen in the above and the small mesh screen under the large ones, keep continuously screening. In the process of crushing, grinding and classification, we should notice that not let the dust spread, sealing the device and recycling refractories in duster. The left dust also can be added to raw materials of landscape bricks.

Ladle Nozzle

Introduction

Ladle Nozzle are made from corundum, bauxite, flake graphite, antioxidant and phenolic resin formed on heavy duty presses in harden steel or carbide die by using white fused alumina. To obtain maximum packing density, nozzles are fired at extremely high temperature in order to increase corrosion resistance to metal and slag the fired nozzles are further processed.

Advantages

They show the features of excellent thermal shock resistance, good excellent corrosion and erosion resistance, strong cracking resistance, long service life etc.

Application

These products have been widely used in steel plant.
