Clay Castable Details

Features

1. Good high temperature performance.

2. High strength at room temperature.

3. Good spalling resistance.

4. Good plasticity.

Production process: material selection - ingredients - mixing - packing - storage

1, material selection is a very important process, is an important link to ensure its production, according to the formula and use of suitable refractory clay castable aggregate, powder, binder, additive.

2. The batching is to select the particle size of selected refractory raw materials according to their grades according to the formula, and strictly control the particle size of aggregate and powder.

3. When stirring, first stir the powder evenly and then stir the aggregate evenly. Add the stirred powder to the aggregate and then mix and stir. Control the stirring time. The time should not be too short, generally 8-10 minutes.

4. Put the stirred clay castable into the ton bale, and equip with additives and binder, and then package.

5. The packed castable shall be stored in the warehouse, and the date shall be marked and treated as moisture-proof and waterproof

Precautions for Use

1. Strictly control the water consumption when making mud on site.

2. Pay attention to vibration time and vibration mode during construction.

3. Control the baking process after pouring and forbid the heating too fast to prevent the construction body from cracking.

Application

Soaking pit and steel rolling furnace, lining of various heat treatment furnace, boiler, shaft kiln, rotary kiln pre-tropical furnace, blast furnace, electric furnace, converter and other industrial kilns.
