This non-blast process for the production of pig iron, cast iron, steel melt and nearly pure iron is carried out in a single furnace based on a tank-type design. Said types of iron melt can be produced in such single furnace individually or simultaneously in different combinations. The furnace interior is divided into immediately adjacent side-by-side chambers, at least one being an ore reduction chamber and at least one being a secondary chamber. Ore introduced into the top of the ore reduction chamber moves downward to the bottom of this chamber and is at first converted into sponge iron, which, absorbing carbon, is then converted into iron-carbon alloy in the form of a flowable layer at temperatures close to its melting point at about 1150 degrees C. while said flowable layer is collected on the bottom. In the melting zone of the secondary chamber such flowable semifinished product is completely melted, producing pig iron.

This furnace for melting inorganic materials comprises a plurality of spaced-apart inner walls dividing the furnace interior into a plurality of chambers, at least one being a liquefying chamber and at least one being a secondary chamber. Each liquefying chamber is provided with a crown and charge ports adjacent the edges of the crown through which batch material is fed into the liquefying chamber. Batch material entering through one of the charge ports moves down an inclined surface of one of the inner walls where it is heated and part of it liquefied by a flame present in the associated liquefying chamber. This liquefying chamber collects liquefied batch at its bottom and hot gases above the liquefied batch. Between the liquefying chamber and an adjacent secondary chamber, there are one or more passages through which: (i) liquefied batch from the liquefying chamber can flow into the secondary chamber and collect on its bottom and (ii) hot gases from the liquefying chamber can flow into the secondary chamber and pass over the liquefied batch in the secondary chamber.
