Insulation your Tundish with NRSTEEL Boards -lower cost and saving energy-easy to install- longlife span !
Our NRSTEEL boards protect the lining of Tundish and help you reduce your energy loss.
There are many different high temperature insulation material for steel ladle and tundish insulation to choose, such as refractory castable, vermiculite board, VIP board, CS-board, etc. we give you a full solution basing your needs.
The permanent insulating lining on the tundish is a basic prerequisite for preventing heat loss during
Heating (hot tundish practice) Pouring The casting process and also to prevent the tundish vessel from overheating
Experience has shown that the insulating calcium aluminate fibre mats, which are commonly used, already begin to breakdown during the bricklaying or casting of the permanent lining, as well as when they are drenched with mortar or poured concrete. As a result, the lining loses its insulating properties even before its initial use and also destabilises the ladle lining. High-strength and high-density calcium silicate boards are an excellent alternative to conventional fibre mats. This is based on the following attributes:
extremely high tensile strength (15 MPa) and the excellent insulating effect ( ג= 0,22 W/mK at 100°C) Easy to work with and install They do not lose their insulating properties while the ladle is transferred to the tundish
NRSTEEL 800 Insulating Boards can be purchased with dimensions measuring 1200 mm x600 mm and thicknesses ranging from 10 to 30 mm. Conventional tools are all you need to work with the boards, for example to make holes for anchors or cut the boards down to size.
NRSTEEL 800 Insulating Boards are not only suitable for insulating tundish vessels – they are also designed for use with pig iron ladles, torpedo ladles, electric arc furnaces and steel casting ladles.
