摘要： PURPOSE:To manufacture the titled ore with a low cost by using a large quantity of coarse grain ore, by compacting materials such as iron ore, cement, cokes, lime stone, water, immediately bringing the green compact into contact with gaseous carbonic acid, then drying and curing it to a prescribed hardness. CONSTITUTION:A material 2 composed of mixture of iron ore fines, cement, cokes fines, lime store fines and water, etc. is supplied to a compacting roll 3 from a hopper 1 to compact it. In this case, water saturation ratio is adjusted desirably, to 0.15-0.9. A green compact 4 obtd. thereby is exposed to gas contg. >=5vol% CO2 at a gaseous CO2 curing part 5 immediately after compacting, to cover the surface with CaCO3 and harden it. Thereafter, the compact 4 is carried to a yard 7 by a conveyer 6, and uncalcined briquetted ore having strength required for charging into blast furnace is obtd. by drying and curing, etc. for 10 day. As the other aging method, gaseous carbonic acid treatment by waste gas contg. it and drying treatment, or blasting treatment, etc., of vapor or hot wind of the compact, by packed tower, etc., are effective.

摘要： PURPOSE: To produce uncalcined lump ore at a high molding yield with good efficiency by pelletizing preliminarily a mixture composed of powder ore and cement then subjecting the pellets to roll molding thereby forming lump ore.
CONSTITUTION: The above-mentioned mixture is preliminarily pelletized prior to rolling molding of said mixture in the stage of subjecting the mixture to roll molding to form the lump ore. The density of the molding is made higher than the density of the untreated mixture by the preliminary pelletization, by which the bite to rolls in the subsequent roll molding and the interaction among the particles as well as the strength and molding yield of the molding are improved. The above-mentioned preliminary pelletization is executed by pseudopelletization in which the molding is simply pelletized by a mixer, etc. or minipelletization in which the molding is made into small pellets sized about 5mm by a pelletizer. The raw material having poor moldability is efficiently lumped by the above-mentioned method.

摘要翻译：目的：通过预先制备由粉矿和混凝土组成的混合物，以高效率生产未煅烧的块矿，然后对其进行辊压成型，从而形成块状矿石。构成：在将混合物进行辊压成型以形成块状矿石的阶段之前，将上述混合物预先造粒，然后在对所述混合物进行轧制成型之前进行造粒。通过初步造粒使成型体的密度高于未处理的混合物的密度，通过该成型，随后的辊成型中的咬合和颗粒之间的相互作用以及模制品的强度和模制成品得到改善。上述初步造粒是通过伪造粒进行的，其中模制品通过混合器等简单造粒或小型化，其中成型制成尺寸为约5mm的小粒料。通过造粒机。成型性差的原料通过上述方法有效地集中。

摘要： PURPOSE:To manufacture the titled ore for blast furnace having large reposing angle, by compacting a mixture of iron ore powder, cement, coke powder, lime stone powder, water, etc., regulating water saturation ratio to a specified value, and curing said body in gaseous carbonic acid having a specified concn. CONSTITUTION:Said mixture is press compacted by roll. The green compact is regulated to >=0.15- =5vol% gaseous carbonic acid. Mixture of one or >=2 kinds among cement clinker powder, gamma-2CaO.SiO2 powder, beta-2CaO.SiO2 powder, wollastonite powder, blast furnace slag powder, steel making slag powder, slaked lime powder can be used for substitution of cement. By this way, the titled ore having large reposing angle and preventing segregation phenomenon during feeding it into blast furnace, is manufactured.
