Based on historical documents and field survey, the wood bellow of No.3 iron smelting furnace in Liao Dynasty was reconstructed at Shuiquangou, Yanqing in Beijing. Its ultimate wind pressure and the speed were estimated. The ventilate ability for its portion was calculated respectively. Furthermore, the flow field in the furnace blasted with the wood bellow was simulated with software FLUENT. The effect on the iron smelting techniques for single-tuyere blast furnace with this blast ability of the bellow was discussed.

To use effectively internal raw material base, JSC “Ural Steel” accomplished I category major overhaul of the blast furnace No. 2. The main purpose of the overhaul was to design a rational profile which could ensure an ability to operate with a charge containing 95 % of Mikhailovskii GOK (mining and concentrating plant) pellets having basicity of 0.5 by CaO/SiO2. The blast furnace No. 2 having useful volume of 1232 m3, was constructed by design of Danieli Corus, the Netherlands, and was blown in on December 30, 2020. In the process of guarantee tests, step-by-step increase of Mikhailovskii GOK pellets (Fetotal = 60.5 %, CaO/SiO2 = 0.5) content in the charge iron ore part was being accomplished from 55 to 95.1%. Charging of the blend containing pellets in the amount of 55% of iron ore part, was done by charging system 4OOCC + 1COOCC (Ore - Coke) with filling level 1.5 m. Under conditions of pellets part increase in the blend, the charging system was changed to decrease their content at the periphery, to increase it in the ore ridge zone and make it intermediate between periphery and the ore ridge. At the pellets share in the iron ore raw materials 0.75 the charging system was used as the following: 3OOCC + 1COOC + 1COOCC, while at the content 95.1% the following charging system was used: 2COOC + 2COOC + 1COOCC. It was noted that in the period of guarantee tests the furnace running was smooth. The average silicon content in the hot metal was 0.70% at the standard deviation 0.666. Sulfur content in the hot metal did not exceed 0.024%, the blowing and natural gas consumption figures were 2100 m3/min and 11000 m3/min correspondently, oxygen content in the blowing 26.5%, hot blowing and top smoke pressure figures were 226.5 and 109.8 KPa correspondently. The productivity of the furnace was reached as high as 2358 t/day at the specific coke rate 433 kg/t of hot metal. After guarantee tests completion, the pellets content in the iron ore part was decreased gradually from 95 down to 50%. The decreasing was made by 5% in every 6 hours of operation. Application of the mastered technology of the blast furnace No. 2 with the increased share of pellets will enable to stably supply the blast furnaces No. 1, 3 and 4 by iron ore raw materials in the proportion of 30-35% of pellets and 65-70% of sinter.

Mr. V. E. Nash-Williams reports discoveries on three sites. (1) At Llantwit Major, Glamorganshire, where a house was partially excavated in 1888, trial cuttings showed that the structural remains covered an area of about 2 acres, enclosing roughly a square of about 300 ft., on the N, S, and W sides of which were the main buildings with detached outbuildings on the E side. In its final stage the plan was of winged-corridor type with main range on the W and others to the N and S, the latter possibly additional; it was fronted by an internal colonnade of imported freestone and faced on to a cobbled courtyard. A subsidiary range had been tacked on at right angles to the N wing. The walls of local limestone and sandstone remained up to 6 ft. and were decorated with coloured plaster; the floors were mostly of opus signinum. A hypocaust or furnace-chamber in the western or main range, after long use, had been filled in with refuse and a small iron-smelting furnace had been built over it. Two rooms in the N wing, opened in 1888, were cleared ; much of the geometric pavement survived. Three or four more skeletons were found ; they had been buried in rough cists sunk into the pavement or cut through the walls, and therefore at a period when the house was no longer in use. A massively constructed outbuilding, measuring 80 by 26 ft., stood just within the remains of a ditch system. (2) At Caerleon a trench was cut on the SW side of White Hart Lane in the praetentura of Isca abutting on the SE defences. It revealed the primary clay rampart, 15 ft. wide and 6 ft. high, with the inner face of the latest stone rampart outside it ; inside the rampart, and between it and the rampart roadway, a stone building had been inserted (cf. JRS xix, 182). The roadway was 20 ft. wide and heavily metalled and was bordered by the stone culvert of the main drainage-system. On the inner side of the roadway the walls and floor of a stone building, probably a barrack-block, were found.

Abstract. Technological knowledge of the use of metals is inseparable from human knowledge in the processing pyrotechnics of fire as a power in high temperature processes for producing objects. The fire is used for smelting and casting in melting furnaces. Metal smelting furnace is a heat production device, which is used to purify the metal, in this case iron. This paper aims to determine the development of ferrous metal smelting furnace technology in Indonesia with the library research method from the results of previous studies. Based on the results of the analysis, there are four technologies for smelting iron, namely pit kiln, bloomery furnace, blast furnace, and induction furnace. Of the four technologies, three are in use in Indonesia, namely bloomery furnace, blast furnace, and induction furnace.
