Product category: Refractory bricks
Fireclay brick
Fireclay bricks TRISAM are produced on the base of the top quality calcinated fireclay, refractory clays and kaolins.
Two different technological processes – dry and semi-dry pressing are applied for the manufacturing.
This is carried out on computer controlled production lines.
These are intended above all for the consumption in the metallurgical industry. There they are used for the linings of hot-blast stoves, blast furnaces, ladles, stopper rods, hollow-ware, ceramic recuperators, heating furnaces etc. Furthermore these products are used in the ceramic and chemical industries and other branches where application of refractory materials is needed.

Product category: Insulating materials and products
Insulating products
Insulating products marked TRIZOL HBU and HB are effective insulating materials for service temperatures exceeding 1300°C. They are manufactured on the base of high-quality kaolins, refractory clays, aluminium oxides, expanded polystyrene and special additives.
Materials marked TRIZOL RI are insulating products that are used for applications where service temperatures do not exceed 950°C. They are made of expanded perlite, refractory clays and additives.
The whole range of insulating products can be manufactured in almost any shape according to customer´s wish. There is a huge number of applications in variety of industrial branches, where insulating products are used as insulating linings to save heat losses or protect steel castings.

About us
Company portrait
The beginning of refractory materials production in Třinec reaches back to the first half of the 19th century when the Czech Chamber started to produce raw and cast iron by the river Olza. The first refractory materials were used for the blast furnace castings in aggregates working in iron foundry and enamel plants. Gradually production expanded and products for coking plant steelworks and rolling-mills were made. In 1889 from the original small workshop a refractory plant which satisfied the whole need of iron factories came to existence. Approximately 20.000 tons of shamotte and silica materials were produced in the factory. Owing to the increased steel production and change of requirements on assortment and quality of delivered refractory materials a new company was put into operation in 1961 and enabled the production of 75.000 tons of shamotte, high/alumina, siliceous and magnesite products.
In 1994 in the course of the privatisation of TŽ (Třinec ironworks), linking to the long-time tradition of Třinec ceramic and refractory production, an independent private company REFRASIL, Ltd was founded and in a relatively short period of its existence it earned a prominent position in the temporary Czech metallurgical ceramics industry.
