On April 19, 1917 presented H.J.E. Wenckebach are plans for a blast furnace company in the Netherlands to set up consisting of three blast furnaces, a coking plant by-products plant and a cement plant for processing of blast furnace slag. The result was the creation on 31 May 1917 the Committee for establishment of a blast furnace and steel-rolling mill in the Netherlands “, with the aim of setting up an integrated steel company, steel mill and rolling mill.
First phase KNHS
If location was chosen because of the Rotterdam Ijmuiden above solid ground. Started with a building plan for the first phase consisted of two blast furnaces, a coke battery and the necessary infrastructure as an outer and inner harbor, rail yards, power plant and plant products for the cleaning of coke gas
Integrated steel plant
In 1931 a by Hoogovens Steel Engineering was established to conduct research to further expand the company. For the processing of the own pig iron was chosen for the production of cast-iron pipes according to a self-developed casting process. in 1935 following plans for the construction of a steel according to the Siemens-Martin process and a rolling mill for thick plate.
This second development achieves its original Hoogovens objective,
a integrated steel plant and Hoogovens is a national basic industry.
After the Second World War as a national broadband plan the revitalization started. The State of the Netherlands was, with Marshall, the Breedband NV founded.
Transporting hot metal in “mixers”
From the blast furnace, the liquid pig iron tapped and poured into mixers
No. 3 mixer pour the hot metal in the casting of the gutter pig iron casting machine,
Pig iron casting machine,
In the southern part of the Iron Park, west of the center, was on 25 november 1948 the pig iron casting machine, into use. In 1967, the trays replaced by a new model with deeper notch. End of 1969 brought an end to the selling sandwiches and the caster was decommissioned.
Van Leer’s Walsbedrijven NV > Walserij Oost
Van Leer’s Waltz Companies NV started in 1937 with the construction of a mill at Hoogovens site. June 1938 was rolling into production, followed by the profile and strip rolling mill in 1939. In 1941, Van Leer’s Waltz Companies acquired by Hoogovens and continued as a mill east. Eastern mill stopped its production activities in April 1953.
The steel ingots from the steelworks were in the slabbing mill in putovens to about 1300 ° C heat. The blocks were then rolled out to a duowalstuig thick plates of 10 to 30 cm thick.
The cement IJmuiden (CEMIJ) was founded in 1930 by Hoogovens in cooperation with the First Dutch Cement Industry (ENCI) NV The by-product of the blast furnace process, the blast furnace slag, in granulated form is supplied to the CEMIJ, where it is mixed with portland cement clinker, is used for the production of cement.
Blast furnace 4
Blast furnace 4 was on January 14, 1958 lit, as part of the steel plan 1,100,000.
Blast furnace 5
The 1.9 million steel plan included the construction of Blast Furnace 5. This went on 12 december 1961 company.
Rod and Wire Rolling Mill 1964 – 2000
With the commissioning of the Rod and Wire Rolling Mill (SDW) was 2.45 mln steel plan completed.
