HRK castable is a versatile castable refractory made by blending alumina cement with refined refractory aggregate. You can easily build a high-strength and jointless fireproof structure by adding an appropriate amount of water, kneading it at the time of construction, pouring it like concrete, and troweling.

Vibrex castable is a high-strength type low-cement castable refractory with excellent corrosion resistance. The amount of kneaded water is smaller and a precise construction body can be made available.

HRK light castable is a lightweight, and excellent heat-insulating castable refractory. It can also be used as a lining material depending on the temperature range in the back lining of furnaces and heating furnaces.

The HRK stamp is a refractory material to be tamped with an air rammer to form a precise construction body. Due to its dense and excellent heat resistance, it has excellent erosion resistance of molten metal.

HRK plast is a clay-like refractory material for placing, which is made by adding a binder and water with excellent plasticity to a high-grade refractory aggregate. No kneading work is required; it can be installed immediately by placing, hand-painting, or tapping.
