The Catalan forge was invented in Catalonia , Spain, during the 8th century[ citation needed ]. Instead of using natural draught, air was pumped in by a trompe , resulting in better quality iron and an increased capacity.
This pumping of airstream in with bellows is known as cold blast, and it increases the fuel efficiency of the bloomery and improves yield.
The Catalan forges can also be built bigger than natural draught bloomeries. The iron from the Lapphyttan complex was used to produce balls of wrought iron known as osmonds , and these were traded internationally — a possible reference occurs in a treaty with Novgorod from and several certain references in accounts of English customs from the s and s.
Other furnaces of the 13th to 15th centuries have been identified in Westphalia. Al-Qazvini in the 13th century and other travellers subsequently noted an iron industry in the Alburz Mountains to the south of the Caspian Sea.
This is close to the silk route , so that the use of technology derived from China is conceivable. Much later descriptions record blast furnaces about three metres high. However, since blast furnace technology was independently invented in Africa by the Haya people , it is more likely that the process was invented independently in Scandinavia. Simply just building a bigger furnace and using bigger bellows to increase the volume of the blast and hence the amount of oxygen leads inevitably into higher temperatures, bloom melting into liquid iron and, cast iron flowing from the smelters.
Beyond the Blast Furnace
Already the Vikings are known to have used double bellows, which greatly increases the volumetric flow of the blast. In this, the molten iron was tapped twice a day into water thereby granulating it.
This may have included the blast furnace, as the Cistercians are known to have been skilled metallurgists. The Cistercians became the leading iron producers in Champagne , France, from the midth century to the 17th century,  also using the phosphate -rich slag from their furnaces as an agricultural fertilizer.
Origin and spread of early modern blast furnaces[ edit ] Period drawing of an 18th-century blast furnace Due to the casting of cannon, the blast furnace came into widespread use in France in the mid 15th century.
From there, they spread first to the Pays de Bray on the eastern boundary of Normandy and from there to the Weald of Sussex , where the first furnace called Queenstock in Buxted was built in about , followed by one at Newbridge in Ashdown Forest in They remained few in number until about but many were built in the following decades in the Weald, where the iron industry perhaps reached its peak about Most of the pig iron from these furnaces was taken to finery forges for the production of bar iron.
As a starting point, the blast furnace is seen as a simple iron ore smelter, while gradually the physical, chemical and metallurgical background of the blast furnace process is clarified.
The book focuses on the control of the blast furnace process with respect to thermal control, gas flow control and casthouse operation. In this book, all essential process details are described and a special focus is on optimization of coal injection.
In other words: This publication was and can be used as an introductory text for students of metallurgy as well as for blast furnace operators and management. The latter will benefit to solve operational problems and process optimization issues.
The authors have very extensive experience as operators as well as consultants to many steel plants worldwide. With Modern blast furnace ironmaking - An Introduction the reader has a compact compendium of the blast furnace process available: We gratefully acknowledge the contributions of Mr.
Cor van der Vliet and Mr.
Hisko Toxopeus, who co-authored the first two editions of the book and agreed to hand over future editions of the book to a next generation. The present global status of each process is examined, projections for the future are made, and processes are compared. Beyond the Blast Furnace is valuable reading for process developers, because it gives them a complete picture of various process options.
Conventional iron- and steelmakers as well as researchers and practitioners working in the area of alternative processes of ironmaking will also benefit from this ready reference. The book is an ideal text for undergraduate and postgraduate students in metallurgy.
